1.0 INTRODUCTION 1.1 General Description

The Allegro™ 6800 Mobile Imaging Table is designed to safely hold a patient in the proper position undergoing radiographic or surgical procedures. It is a stand-alone, single-pedestal AC power or battery-operated table designed to position a patient in a prone, lateral or supine position during radiographic or surgical procedures. The table has a 2” (5 cm) MIZUHO OSI® Tempur-Pedic® pad. The TEMPUR® used in the manufacture of MIZUHO OSI® pads has viscoelastic properties and is a temperature sensitive material, becoming softer where the patient’s body is making the most contact with the surface and remaining firm in areas where less body contact is being made. Pressure is distributed evenly over the entire surface area. The pad is radiolucent, MR safe and latex free. The benefits of using MIZUHO OSI® Tempur-Pedic® are improved pressure management, reduced shear forces and enhanced patient comfort. The table has four primary electrically powered functions; up/down, left/right lateral roll (tilt), trendelenburg/reverse trendelenburg and X-Y translation. These motions are performed by electromechanical actuators and electric stepper motors. The table is controlled by means of a low voltage hand pendant which has the functions clearly labeled. In addition to the hand pendant, a joystick controls the X-Y translations of the table top. Positive floor locks are employed to stabilize the table in the operating location.

2.0 GLOSSARY OF TERMS

NOTE: The following terms are used throughout this owners manual. A thorough understanding of these terms is necessary to properly operate this table. 2.1 Basic Assumptions Of Patient Orientation On The Tabletop Our glossary of terms and technical procedures assume the patient is oriented with their head at the front of table and their feet at the rear of table as described below. The hand control functions are oriented for this position only. PEDESTAL END, or rear of table, indicates the power cord end of the table, where the control panel is located. CANTILEVER END, or front of table indicates the opposite end of the rear of the table or, the column pedestal. PEDESTAL, refers to the main column structure that supports the tabletop. Left side, of the table refers to the left side of the table as you stand by the pedestal end and look down the table. This also corresponds to the hand pendent button labeled LEFT LATERAL ROLL. Right side, of the table refers to the right side of the table as you stand by the pedestal end and look down the table. This also corresponds to the hand pendant button labeled RIGHT LATERAL ROLL. Raise the table, refers to raising the height of the table. This also corresponds to the hand pendant button labeled HEIGHT UP. Lower the table, refers to lowering the height of the table down toward the floor. This also corresponds to the hand pendant button labeled HEIGHT DOWN. Reverse trendelenburg, refers to moving the cantilever end of the table up. The corresponding hand pendant button is labeled REV. TREN. Trendelenburg, refers to moving the cantilever end of the table down. The corresponding hand pendant button is labeled TREN. Return to level, or level the table, refers to returning the tabletop to a state level regardless of height. The corresponding hand pendant button is labeled return to level. Holding the RETURN TO LEVEL button longer than approximately three seconds will lower the tabletop to its lowest position. Top home, refers to returning the table top to its home position after longitudinal or lateral travel. The corresponding hand pendant button is labeled TOP HOME. The tabletop in the home position is centered over the pedestal pads in its side to side travel and to its extent of travel toward the pedestal end in its longitudinal travel Unlock the floor locks, raise the floor locks, turn off the floor locks, refers to allowing the table to freely roll on its wheels once the floor lock feet next to the wheels, raise off the


floor. The floor locks, when down, prevent the table from moving on its wheels. The corresponding hand pendant buttons labeled FLOOR LOCK. Control panel, is a panel of buttons and lights located on the pedestal end of the table. Floor locks and tabletop home can be controlled by depressing the corresponding button labeled UP TO UNLOCK, DOWN TO LOCK or TABLE TOP HOME. Hospital grade outlet, refers to a 120VAC outlet properly wired with earth ground. Generally this is: neutral to common = 120VAC; neutral to ground = 120VAC; common to ground less than zero point five (0.5)VAC, and will be marked with a green dot.

4.3 Hand Pendant

WARNING: A hand pendant can be plugged in at the pedestal end (back) or the cantilever end (front) of the base, or both locations with two hand pendants. If a hand pendant is removed or added while the table is operational, the table must be shut down for 30 seconds. When turned on, the floor locks must be reengaged. It is best only to plug or unplug hand pendants when power is turned off.

The table is controlled by means of a low voltage hand pendant which has the functions clearly labeled (see figure 6). The hand pendant should be plugged into the receptacle labeled “hand pendant” on either the back or the front of pedestal. The hand pendant is intended to be hung on the side rail independently, placed either with the swivel mount or without. The swivel mount allows the hand pendant to be mounted horizontally on the table. The hand pendant clip slides in the top of the swivel mount and the swivel mount slides on the side rail or auxiliary clamp.


Height: To adjust the height of the table press and hold the appropriate HEIGHT UP or HEIGHT DOWN button until the desired height is achieved. Lateral roll: To adjust the lateral roll press and hold the appropriate LATERAL ROLL button. Note that when lateral roll is within +/- 2° of level the green level indicator will illuminate. Trendelenburg / reverse trendelenburg: To adjust the trendelenburg position of the table, press and hold the appropriate TREN or REV.TREN button. Note that when trendelenburg tilt is within +/- 2° of level the green level indicator will illuminate. Table top translation: The hand pendant is equipped with TOP FORWARD, TOP AFT, TOP LEFT and TOP RIGHT translation button. When one of the translation buttons is depressed the table top will translate in the given direction at constant speed. NOTE: The table can also be translated at variable speeds using the joystick (see section 4.4).

WARNING: Battery status: The hand pendant is equipped with a two color battery status LED. If the indicator is green, the battery is charged and the table is ready for use. If the indicator is red, the battery must be charged for a minimum of 3 hours (see section 7.0 for complete Battery Charging instructions). NOTE: The table can be used on line power if the battery is not fully charged.


The hand pendant is equipped with a TOP HOME button and a RETURN TO LEVEL button. The TOP HOME button is used to return the table top to it’s X-Y home position. The RETURN TO LEVEL button returns all functions to a preset level position. The top home and the return to level buttons must be depressed and held continuously until the function is complete.

Return to level: Press and hold the RETURN TO LEVEL button, this will 1) level lateral roll, 2) level the trendelenburg and 3) bring the table to its lowest height position.

The controller considers the table to be level if it is within +/- 2° of 0° level. If the RETURN TO LEVEL button is pressed while the table is within this range, it will not move. If it is required to adjust the table to a position closer to 0°, simply press the appropriate function button on the hand pendant until the desired position is achieved.

Top home: The X-Y home position of the table top can be achieved by pressing the TABLE TOP HOME button located on the control panel of the pedestal or the TOP HOME button on the hand pendant. This position is defined as the table top being centered in its side to side travel and to its extent of travel toward the pedestal end in its longitudinal travel. 4.4 Joystick Control – Interactive Proportional Speed Control™ (IPSC) The lateral and longitudinal translation movement of the table is controlled by a joystick control mounted on the side rail or auxiliary clamp on either side of the table top. The Allegro™ 6800 has 2 speed ranges of operation for longitudinal travel. Lateral travel is always performed at the normal speed setting. An illuminated green light on the top of the joystick control indicates which speed is engaged. A speed button on the top of the joystick control can be pressed once to switch between speeds. It should be noted that the joystick provides Interactive Proportional Speed Control™ (IPSC). This means that the Allegro™ 6800 travel speed will increase from stop to full speed within the selected range in proportion to how far the joystick is pushed.

Figure 7: Joystick control

To use the joystick control slide it onto the side rail or auxiliary clamp and plug it into the receptacle labeled joystick on either end of the pedestal of the Allegro™ 6800. The locking lever of the joystick control must always be rotated toward the pedestal end of the table to lock it to the side rail or auxiliary clamp. Correct orientation of this lever insures that the direction of travel of the Allegro™ 6800 will be consistent with the direction of the joystick movement.

WARNING: Failure to engage the joystick locking lever in the proper direction will result in travel in the direction opposite of the joystick motion.

The joystick control includes an activation button (red button) that must be depressed to activate the joystick. This feature prevents unintended motion of the Allegro™ 6800 if the joystick is inadvertently pushed. To translate the Allegro™ 6800, press and hold down the JOYSTICK ACTIVATION button and then push the joystick in the intended direction of travel. Release the joystick when the desired position is achieved. The table will move at a speed that is proportional to the position of the joystick from the starting center position. Pushing the joystick further from center moves the table faster in that direction. Releasing the joystick activation button stops the table in any position.

NOTE: Although the Allegro™ 6800 is designed to travel laterally and longitudinally at any tilt or trendelenburg angle, it is recommended not to translate the table at high speed under full load (i.e. 450 lb. patient) when it is at extreme tilt or trendelenburg angles. NOTE: If the joystick is moved off center before the joystick activation button is pressed the table will start moving at that speed proportional to the position of the joystick. This can result in sudden jerky or rapid movement of the table top. Therefore, do not move the joystick off of center before pressing the joystick activation button.

7.0 THE ELECTRICAL SYSTEM

7.1 Description The electrical system provides control of all the table functions and is comprised of a power cord, an on/off circuit breaker switch, wire harnesses, a power supply, a controller circuit, a hand pendant, a joystick control, floor lock jackscrews, various electromechanical actuators, two stepper motors and two batteries. The electric motor driven leadscrew-type actuators manipulating the height, lateral roll and trendelenburg functions are controlled by the hand pendant. The floor lock buttons raise and lower the table floor lock feet to the floor. The translation motion of the table top is controlled by the joystick control and the hand pendant and driven by the stepper motors. Drawing number 6800-1003 is the Electrical Wiring Diagram for the Allegro™ 6800 Imaging Table. The input power requirement for this table is 120 VAC 60Hz, 5 Amp or 230 VAC 50Hz 2.5 Amps as indicated on the serial number label. Drawing number 6800-1004 is the Electrical Wiring Diagram for the 230 volt model 6800 Imaging Table. 7.2 On/Off Circuit Breaker Switch

An illuminated on/off circuit breaker main switch is located on the back of the pedestal end of the base of the table (see figure 4). When illuminated, it indicates that the table is plugged into a live electrical outlet and the power is on, (when the table is turned on using battery power, this switch will not illuminate). This switch also serves as a circuit breaker. In the event of an overload condition this switch will trip off. To reset, push to the off position and then the on position. NOTE: Determine the source of the overload prior to resetting this switch. 7.3 Component Circuit Breakers The electrical system includes three individual component circuit breakers that provide protection for the major components of the system. These circuit breakers are located in the base at the pedestal end of the table (see figure 4). If a short circuit occurs, the affected circuit breaker will trip as evidenced by a button protruding from the circuit breaker access hole. To reset, press the button in and release.

NOTE: Determine the source of the overload prior to resetting this button. 7.4 Power Cord The table is equipped with a standard IEC power cord with the appropriate hospital grade connector. The power cord is connected to the table at the IEC power entry socket located on the base of the pedestal near the on/off switch. 7.5 Floor Lock System The Allegro™ 6800 Mobile Imaging Table floor lock secures the table by powering 4 jackscrews to lower four legs onto the floor and unloading the swivel casters. It is operated by depressing the DOWN TO LOCK button located on the control panel or the FLOOR LOCK button on the hand pendant. The lock button is pressed and held until the floor lock is completely engaged as evidenced by the illumination of the floor lock


indicator light on the control panel or the hand pendant. This button applies electrical current to each of the four jackscrew motors. Each leg is monitored by the controller for contact with the floor. In the case of an uneven floor, it is possible that one or more legs will continue to extend until firm contact is made with the floor. Complete locking is evidenced by the illumination of the green LOCKED WHEN LIT indicator located on the control panel and the FLOOR LOCK ON LED located on the hand pendant. The table should not move on its wheels when floor locks are engaged. NOTE: The table controller requires that the floor lock system be completely engaged before any other function can be operated. If the hand pendant or the joystick will not operate the table, verify that the floor locks are completely deployed, such that the table does not move. To unlock the floor lock, press and hold the UP TO UNLOCK button until the amber STOWED WHEN LIT indicator on the control panel and the FLOOR LOCK STOWED LED located on the hand pendant are illuminated indicating that the legs are completely retracted.

WARNING: Press and hold DOWN TO LOCK button until green LOCK WHEN LIT light is illuminated on the control panel, and that the FLOOR LOCK ON LED on the hand pendant is illuminated. Table is locked if it cannot move on its wheels. Ensure each floor lock is fully engaged before use. 7.6 Battery Charging The Allegro™ 6800 Table is designed to use two 12 volt batteries in series to provide 24 volts. When battery status LED on the hand pendant is red, batteries need to be charged. To charge the batteries, simply plug the power cord into an appropriate hospital grade outlet and turn the power switch on. While in storage, it is desirable that the table be plugged in and the power switch turned on so that the batteries remained charged. If this is not possible, the batteries must be charged for at least three hours a week. This can be accomplished when using the table under line power. To ensure proper battery function, it is recommended that the batteries be charged for at least 3 hours within the previous 48 hours prior to use. The battery status LED on the hand pendant must be illuminated green when the table is on. The batteries should be replaced every 5 years or when they fail to hold a charge. 7.7 Power Supply - AC & DC Operation

The system power supply converts AC power, 120-volt, 60Hz or 230-volt, 50Hz into 24VDC (nominal) operational power. There are four 24VDC output ports, each with a circuit breaker for thermal and short-circuit protection. Two are unregulated at 10-Amps with voltage between 36VDC and 22VDC depending on load and one at 15-Amps with voltage between 36VDC and 22VDC depending on load. The fourth DC output port is regulated at 24VDC +/- .25 ,and has no circuit protection within the power supply tray. When powered from an AC source, the batteries in series are constantly being charged at a variable rate depending on the charged state. Battery charge status is monitored by


the 10-Amp motor controller PCB via a data port on the power supply PCB. A current-sensing circuit switches to DC battery power when it senses no AC power source is available. The 24VDC battery circuit can power and operate all of the on-board systems, motors and actuators. When running on DC battery power the power switch will not illuminate green but LED’s on the hand pendant will illuminate, indicating the battery circuit powers the table. 7.8 Battery System The 6800 Allegro™ Table uses two 12-volt batteries in series to provide 24-volts. When the battery status LED on the hand pendant is red, the batteries require charging. To charge, plug power cord into an appropriate hospital grade AC outlet and turn the power switch to on.

WARNING: While in storage, the batteries should remain charged for a minimum of three (3) hours a week. Using the table while on AC power will also charge the batteries.

• Normal battery operation is approximately 5 hours at 10% duty cycle. • If recharge is required, charge a minimum of three hours. A full charge should be

available after 18 hours. • If battery fails to hold a charge it should be replaced. Replace only with identical type

and size battery (see Replacement / Spare Parts List). • Replace both batteries at the same time. Also replace foam battery blocks on top of

battery. • Batteries should be replaced once every five (5) years. • Whenever the battery cover is opened, check battery for signs of corrosion. Battery

terminals should be clean and free from corrosion, oil, grease, dirt, or other contaminants.

• Battery ordering number: NV0801; failure to use an approved Mizuho OSI battery, voids warranty and can cause harm to equipment.

1. Turn power switch off, wait 30 seconds for discharge, unplug power cord from wall

outlet. 2. Remove pedestal-end base cover by removing the six screws using 1/8 in hex key.

WARNING: Disconnect batteries only with power cord unplugged and power switch off.

This symbol indicates the external stud that is at the same potential as the equipment chassis. If the AC power cable is not connected to an outlet with a protective earth ground, this external stud should be connected to a protective earth ground.


3. Connect battery terminals as follows (see figure below): a. Red wire: Battery A positive terminal to power supply terminal E16. b. Yellow wire: Battery A negative terminal to battery B positive terminal. c. Black wire: Battery B negative terminal to power supply terminal E17.

Perform the following test to confirm proper battery connection: 1. Verify power cord is unplugged from AC wall outlet. 2. Turn power switch on (utilizing battery power) and verify all hand pendant LED’s

illuminate on and off in sequence. 3. With properly connected batteries, the hand pendant battery status light illuminates

green or red.

• A green battery-status light indicates batteries are charged and installed correctly.

• A red battery-status light indicates batteries are connected correctly but are in need of charging. If a charge is required, plug power cord into wall receptacle; turn power switch on, verify it illuminates green (AC is provided to the charger). Charge for at least three (3) hours.

NOTE: If this does not happen, immediately turn power switch off; verify proper battery connections, verify hand pendant is fully connected to table receptacle. Repeat test again. If problem continues, contact Mizuho OSI Customer Resource Group at 800-777-4674 for further assistance.

8.0 CLEANING 8.1 Cleaning And Disinfecting

NOTE: Never pour any liquid directly onto the table. Never subject the Allegro™ 6800 Mobile Imaging Table to any cart or equipment washer.

1. Table exterior

• Exterior surface should be regularly wiped clean with a mild detergent solution and wiped dry with a soft lint-free cloth.

NOTE: Do not wipe the support rails for the translating table top. These should remain with a light coat of oil at all times.

• Care should be taken to avoid exposing the table to excessive moisture. Flooding, fogging or steam cleaning is not recommended.

• Blood or other fluids, etc., if allowed to remain on the table for a long period of time, will require special cleaning to remove. A 5% acetic acid solution or white vinegar and water solution is especially good for this purpose.

• Staining and discoloration of plated or stainless steel surfaces can be corrected by cleaning with a good commercial cleaning compound, such as Stainless Steel Magic or Acme White Finish, and then buffing the surface by hand.

• To disinfect exterior surface use a quaternary ammonium or similar type disinfectant compound according to manufacturer's directions for use. Wipe dry with a soft lint-free cloth.

USE OF IODOPHORS WILL CAUSE STAINING

NOTE: Failure to thoroughly dry surface after cleaning and disinfecting may result in rust.

2. Casters

• Casters should be cleaned and disinfected in the same manner as table exterior. Access to the casters is achieved by removing the sheet metal enclosures at each end of the table base.

NOTE: Before removing any sheet metal covers the table must be turned off and unplugged. Dangerous high voltage may be present in the circuitry under the covers. This task should be performed by trained technicians only.

3. Table Pad MIZUHO OSI® Tempur-med® Pad IMPORTANT: The MIZUHO OSI® Tempur-Pedic® pad should always be stored in a

flat position. It can actually get stiff in cold temperatures and can crack and break if in a rolled position. It is important that you allow the pad to warm to room temperature before attempting to utilize or handle it.

• When handling always grasp by the entire thickness of the pad.


• Do not lift, slide or carry MIZUHO OSI® Tempur-med® pads by grabbing the fabric. The cover may tear or rip.

• The pad is intended to be cleaned in place. It does not need to be rotated or flipped.

• Clean with standard hospital disinfectants labeled for use on table pads. Always dilute and rinse per manufacturer’s label instructions. Wipe dry with a lint free cloth. Do not soak or autoclave pads. The continued use of bleach or highly concentrated chemicals will void the warranty on the cover.

• When cleaning the bottom of the pad or the table top, simply lift one end of the pad, and fold it over onto the other end. Clean the pad or the table top then return the pad to flat on the table top.

4. Table tops

• Disinfect surfaces of table tops according to standard hospital procedure. 8.2 Lubrication 1. Table exterior

No lubrication is necessary. 2. Table interior

The translation and height adjustment sliding mechanisms of the 6800 Imaging Table require periodic lubrication. There are ten sliders in all and each should be lubricated with Thomson Linear Lube grease (or equivalent) once a year. Four sliders are on the lateral translation rails, four are on the longitudinal translation rails and two are on the main table column. Apply the grease through the zerk fittings located on each slide bearing housing. Do not over lubricate. All other components are lubricated for life at the factory and no other lubrication on the table is necessary. 8.3 Table Storage

When not in use the table should be stored in a clean dry environment with temperature between 32 °F & 120 °F (0 °C & 49 °C).


9.0 TROUBLESHOOTING

9.1 Electrical System In the advent of a table malfunction, the first item to investigate is the input power. Be certain that the power cord is plugged into a live electrical outlet and the power switch is on. This is evidenced by an illuminated on/off switch. If none of the functions are operating, the floor lock may not be completely deployed. Press the FLOOR LOCK button until the green LOCKED WHEN LIT indicator is illuminated.

Figure 10: Floor lock override button

WARNING: If the floor lock is deployed as evidenced by visual inspection, all four floor lock feet should be in contact with the floor. Table should not move whether or not the green indicator is illuminated, and the up/down, lateral roll or trendelenburg functions do not operate. The floor lock override button can be used to temporarily bypass the interlock on the floor lock system. This button is located on the underside of the sheet metal housing at the FLOOR LOCK buttons (see figure 10). Press and hold this button while simultaneously operating the desired function on the hand pendant. Once released, no functions will be operable and this button must be pressed again if subsequent table movement is required. This override button only powers the height, trendelenburg and lateral roll functions on the hand pendant and is intended for emergency situations only. If it becomes necessary to use this feature, call Mizuho OSI Customer Resource Group immediately to arrange for table service.

two screws with 5/32 hex key. 6. Move tabletop to maximum right lateral roll using hand pendant. 7. Move tabletop to maximum right-translation position using joystick. 8. Remove right Y-stop bracket (opposite left Y-stop bracket) by removing two screws

with 5/32 hex key. 9. Remove X-Y stage cover by removing four screws, two on each side, using 1/8 hex

key. 10. Turn power off and unplug table. 11. Slide X-Y stage cover off end of tabletop. Left Tilt Cover Removal (The Bell Shaped Housing):

WARNING:

The following procedure requires removing components with the table on, use extreme caution. NOTE: On some older tables, front X-Y stage cover must be removed to access one 4-40 mounting screw. Do not replace this screw during reassembly. 1. Remove seven flat-head screws, using 1/16 inch hex key. 2. Remove three screws located on top surface of left tilt cover using 1/8 inch hex key. 3. Plug table in and turn power on. 4. Move tabletop with joystick to maximum left transitional position. Move tabletop, to

place casting recess (viewed best from below) for best screw clearance and easiest access.

5. Turn power switch off. Wait 30 seconds for discharge, then unplug power cord from wall outlet.

6. Disconnect red wire from battery A positive terminal. 7. Remove left tilt cover.

WARNING: To prevent damage to the sensors use care removing or replacing this cover. Replacement procedure: 1. Cut any cable ties holding the existing tilt sensor wire harness to the tilt sensor

bracket. 2. Gently pull the two sets of wires from the tilt sensor. NOTE: The color coding: White-marked connector goes to white-marked tilt adjust socket. Black-marked connector goes into black-marked trend adjust socket. 3. Remove the tilt sensor by removing two, 1/4-20x1/2 in. cap-head screws using 3/16

hex key.


4. Replace in reverse order. Attach harness to sensor bracket, as needed, with small nylon cable tie. Use care to prevent possible damage by moving parts.

Tilt sensor calibration: NOTE: Use a bubble level resting on the tabletop as a level gauge. The level sensor adjustment screws are accessed from the top of the unit. A two degree maximum dead-band exists for each axis. For return to level to function, the tabletop must be outside of this dead-band. 1. Turn power switch on. The green light illuminates. 2. Press and hold DOWN TO LOCK button until green LOCKED WHEN LIT indicator

illuminates. 3. Raise the tabletop to a comfortable level. 4. Push the LEFT LATERAL ROLL or RIGHT LATERAL ROLL buttons to level

tabletop. 5. Push the LEFT LATERAL ROLL button to tilt the tabletop more than five degrees. 6. Push the RETURN TO LEVEL button to level the tabletop; note the degree of level. 7. Push the RIGHT LATERAL ROLL button to tilt the tabletop more than five degrees. 8. Push and hold the RETURN TO LEVEL button to level the tabletop; note the degree

of level. 9. Turn the tilt adjust screw a partial turn. NOTE: Clockwise will stop the tabletop more to the right, counter-clockwise will stop the tabletop more to the left. The tabletop will overshoot each stopping point, requiring "splitting the difference" to adjust for proper balance.

10. Test the adjustment by:

a. Push the LEFT LATERAL ROLL button to tilt the tabletop to maximum. b. Push the RETURN TO LEVEL button to level the tabletop; note the degree of

level. c. Push the RIGHT LATERAL ROLL button to tilt the tabletop to maximum. d. Push the RETURN TO LEVEL button to level the tabletop; note the degree of

level. 11. Continue adjustments until the tabletop stops from either maximum lateral roll at the

same offset from zero. 12. Trendelenburg / reverse-trendelenburg calibration (TREN/REV.TREN).

a. Repeat steps of left and right lateral roll calibration using TREN/REV.TREN buttons on the hand pendant.

13. Turn power switch off. Wait 30 seconds for discharge, then unplug power cord from wall outlet.

14. Disconnect red wire from battery A positive terminal. 15. Attach left tilt cover.

WARNING:

Use care replacing this cover to prevent damage to the sensors.

16. Place the left tilt cover in its original position. a. Install the three screws attaching left tilt cover, located on top surface, using 1/8

hex key.


b. Move the tabletop with the joystick to maximum left position for best screw clearance and easiest access.

c. Install the seven screws attaching the left and right tilt covers using a 1/16 inch hex key.

17. Attach X-Y stage cover. a. Place the X-Y stage cover onto the tabletop. b. Install the four screws attaching the X-Y stage cover using a 1/8 inch hex key. c. Install the two flat-head screws attaching the left Y-stop bracket using 5/32 inch

hex key. d. Install the two flat-head screws attaching the right Y-stop bracket using 5/32 inch

hex key.
