1. INTRODUCTION The equipment supplied comprises: 1 off Electrically operated hydraulic power pack 1 off Electrical Control Panel c/w Inverter Control Unit The equipment provides the means to move the kiln axially, up and down, in a cyclic manner. There are 2 off thruster roller stations. Each station has 2 off hydraulic cylinders attached to each thrust roller on the kiln. The cylinders are powered by a hydraulic power pack which incorporates the necessary hydraulic valves to control the speed of movement and maximum system pressure. An accumulator is included in the hydraulic circuit at each thruster station. The function of the accumulator is to dampen pressure fluctuations that occur whilst the kiln is running. The kiln is moved uphill, by the flow produced by the pump. Duty and standby pumps are available for use. The pump to operate in duty is selected on the electrical control panel. The uphill speed is controlled by the flow produced. This is varied by adjusting the speed of the electric motor. Further adjustment of the uphill speed is achieved by adjustment of the uphill flow control valve. The kiln moves downhill, with the electric motor stopped. The force exerted by the kiln causes the cylinders to retract. The speed of downhill movement is controlled by a flow control valve on the power pack. The switching points between uphill and downhill movement is controlled by proximity switches. Alarm proximity switches are provided which operate if the kiln’s direction of movement fails to reverse. A solenoid operated valve is fitted into the system to release the pressure within the thruster cylinders if the kiln moves too far uphill. The solenoid is energised by the operation of a proximity switch To reduce the load of the thruster at “B” station a Pressure Reducing Valve 25 is fitted into the cylinder supply line. It is selected by the operation of a 3 port valve 24.

ELECTRICAL EQUIPMENT The electrical equipment is housed in a 600 x 600 Sheet steel enclosure, RAL 7032, sealed to IP55, with local isolation provided by a door interlocked isolator.

The enclosure door of the control panel is fitted with the following: -

a) A Potentiometer which is connected to an inverter which is used to control the speed of the electric motors.

b) Pump Selector Switch to operate which pump is to be used in duty.

c) Local/Remote Selector Switch. This enables the system to be operated from the control panel or from a remote location.

8

d) Manual/Auto Selector switch. This enable the system to be controlled locally in either manual control (via the uphill and downhill push buttons) or automatically where the system is controlled by the proximity switches.

e) Manual operation push buttons. It should be noted that the operation of the thruster system only occurs when the appropriate button is operated.

f) Emergency Stop button. This stops the motor and de-energises the solenoids on valves 17.1 & 17.2

3. OPERATION OF THE EQUIPMENT

Start up / Shut down

On Start-up for the first time the following checks should be made: -

• The overload setting should be checked and adjusted to match the Electric motors.

• The speed of the electric motor, controlled by the setting of the potentiometer and inverter, should be set to minimum.

• The Power Pack Isolation valve (20.1) and the Cylinder Isolation Valves (20.3) must be in the open position

• The hydraulic lines and cylinders should be bled If it is necessary to completely shut down the system the following steps should be undertaken: -

• Ensure that the power pack is not operating • The Local/Off/Remote switch should be selected to OFF • The Control Panel should be ISOLATED

The Power Pack Isolation Valve (20.1) and the Cylinder Isolation Valves (20.3) should be closed. This will ensure that the kiln remains in position and will prevent it from moving. If necessary a hydraulic pump can be connected to the manifold block (13) via the quick release coupling (24). This will enable the kiln to be moved up and down independently of the power pack. The Auxiliary Supply Isolation Valve (20.2) must be open during this time.

METHOD OF OPERATION

(TO BE READ INCONJUNCTION WITH DRAWING No GE-14116H-01)

The operation of the Kiln Thruster Power Pack is via the existing control system and was not part of our scope of supply. MOVING KILN UPHILL When the kiln reaches the limit of downhill travel proximity switch (LS1) is operated. This initiates the “uphill travel mode” and the following occurs: - The electric motor (8) starts. The speed of the electric motor (8) determines the flow produced by the pump and hence the speed of the uphill movement of the kiln. The speed of the electric motor is controlled by the potentiometer on the control panel enclosure door. The hydraulic pump (8) draws oil from the reservoir passing it through the pressure filter (11) and the non-return valves (12). Oil enters the valve block (13) passing over a pump inlet check valve (14). It passes over the uphill flow control valve (16.1) which further controls the speed of the kiln. The solenoid on the Downhill valve (17.1) is de-energised. Oil passes directly to the kiln thruster cylinders via the Power Pack Isolation Valve (20.1), causing the kiln to move uphill. Pump pressure is regulated by Pressure Relief Valve (15.1). Cylinder pressure is regulated by Pressure Relief Valve (15.2). Pressure Gauge (18.1) registers Pump Pressure Pressure Gauge (18.2) registers Cylinder Pressure Oil from the power pack enters the cylinders via the cylinder isolation valves (20.3). Accumulators (21) are provided to dampen the pressure fluctuations that occur when the kiln is rotating.

12

The kiln continues to move uphill until the uphill proximity switch (LS2) is operated. In the event of the operation of proximity switch (LS3) the solenoid on valve (17.2) is energised. This releases the pressure in the cylinders to allow the kiln to start moving downhill. If proximity switch (LS2) fails to initiate the “downhill travel mode” of the system and proximity switch (LS4) is operated an alarm is raised in the control room to indicate the kiln is still moving uphill. REDUCING THE FORCE APPLIED AT STATION “B” If is required necessary to reduce the force applied at Station “B” this is achieved by operating the 3 Port Isolation Valve (25). This exposes “B” station thruster system to the Pressure Reducing Valve (24). This limits the pressure that can be applied by the cylinders at “B” station. MOVING KILN DOWNHILL When the kiln reaches the limit of Uphill travel proximity switch (LS2) is operated. This initiates the “downhill travel mode” and the following occurs: - The Electric motor (8) stops The solenoid on the Downhill valve (17.1) is energised. The kiln forces oil from the Thruster Cylinders through the Cylinder Isolation Valves (20.3) and back to the valve block (13). It passes through the Downhill Valve (17.1), through the Downhill Flow Control Valve (16.2) (which controls the downhill speed of the kiln) and back to the reservoir. The maximum cylinder pressure is regulated by Pressure Relief Valve (15.2). Pressure Gauge (18.2) registers Cylinder Pressure Accumulators (21) are provided to dampen the pressure fluctuations that occur when the kiln is rotating. The kiln continues to move downhill until the downhill proximity switch (LS1) is operated.

13

If proximity switch (LS1) fails to initiate the “uphill travel mode” of the system and proximity switch (LS5) is operated an alarm is raised in the control room to indicate the kiln is still moving downhill. If a Cylinder Isolation Valve (20.3) is closed this would prevent the affected cylinders from assisting the movement of the kiln uphill. However the Non-Return Valves (12.2) enable the kiln to force oil out of the cylinders when it is moving downhill. When the cylinders have been retracted and the kiln starts to move uphill the cylinder(s) can easily be removed. MOVING KILN UPHILL FAST In the event of the kiln being required to move uphill at full speed:- The electric motor (8) speed should be adjusted to maximum of the potentiometer. The uphill flow control valve (16.1) should be wound fully out. If kiln movement has to be increased further the operation of one of the Cylinder Isolation valves (20.3) would enable the flow produced by the pump to pass to only one set of thrust cylinders. During this period the operating pressure developed in the system will increase. MOVING KILN DOWNHILL FAST In the event of the kiln being required to move downhill at full speed:- The downhill flow control valve (16.3) should be wound fully out. If kiln movement has to be increased further the operation of proximity switch (LS3) energises the solenoid on the Emergency Pressure Release Valve (17.2). This enables the release of pressure from the system to enable the kiln to move downhill without any resistance.

4. INSTALLATION & COMMISSIONING

1. Fit the electrical control panel housing the Inverter and Potentiometer.

2. Connect the power cables to the control panel and run cabling from the control panel to the power pack electric motor.

3. Connect the existing solenoid cable to the solenoid on the Downhill Direction

Cylinder Pressure Relief Valve (13.2) fully in. 12. Start the Electric Motor (5). 13. Adjust the Pump Pressure relief Valve (13.1) until a pressure of 350 Bar is

showing on the Pressure Gauge (12.1). Lock off the adjustment screw. 14. Adjust the Pump Pressure relief Valve (13.) until the pressure on the Pressure

Gauge (12.2) drops just below 350 Bar. Lock off the adjustment screw. 15. Open the HP Ball Valves (17) 16. Set the pump to maximum speed and open fully the Uphill Flow Control Valve

(14.1).

15

17. Crack open the hose/pipe work connections at the hydraulic cylinders ensuring

that means are provided to contain the ensuing spillage. 18. Start the Electric Motor (5).

19. After a short while, when the pipe work is filled, a mixture of oil and air will appear through the semi-open joints at the hydraulic cylinders. During this procedure the reservoir oil level should be checked and topped up as required.

20. When only oil appears through the semi-open joints at the hydraulic cylinders

the joints should be re-tightened. 21. The reservoir oil level should be checked and topped up as required. 22. The Electric Motor (5) is started and the system pressures checked. 23. With pressure registered on the Pump and Cylinder Pressure Gauges (12.1 &

12.2) the kiln should start to move uphill. 24. The uphill speed of the kiln should then be adjusted by adjusting the speed of

the electric motor and/or the Uphill Flow Control Valve (14.1). Further adjustment may be required to ensure an uphill travel time of 8 hours.

25. When the kiln reaches its extent of uphill travel the uphill limit switch should

operate. This switches off the electric motor. 26. The Downhill Flow Control Valve (14.2) should be adjusted to ensure a

downhill travel time of 4 hours is achieved.

6. GENERAL HYDRAULIC SYSTEM MAINTENANCE

The following instructions are to provide a General Guide to an oil hydraulic system. It should be noted that many common-sense precautions have not been covered and occasionally faults may occur as the result of a series of events, which could not have been foreseen. Nevertheless, the equipment will function satisfactorily for many years under normal operating conditions, if the following points are observed and carried out. In the case of any doubt or difficulty, do not hesitate to contact G. Elliott Engineering Services Ltd.

A. OIL

The care of oil in the system is of the utmost importance since the oil lubricates in addition to actually transmitting power. Failure to heed the points set out below will usually lead to a stoppage.

1. Use oil of the correct viscosity. The correct type and grade of oil will be found stamped on the nameplate on the machine, if oil of a lower viscosity is used, leaks will occur and the system become inefficient. High viscosity oil will cause sluggish operation.

2. Do not let the oil in the system overheat. Overheating not only breaks down

the oil and causes damage to seals, but, lowers the viscosity thus reducing efficiency. In general, oil temperatures up to 140°F (60°C) are acceptable for the standard mineral oils.

3. Check the reservoir oil level indicator at regular intervals. In the event of a

rapid lowering of the oil level, check all seals in the equipment and all pipe joints for leakage. Keep the oil level as near to `Full' as possible and under no circumstances run the system with the oil level below 20% full. If this is done, air may be introduced into the system with disastrous results.

4. Unless otherwise recommended, a complete oil change must be carried out

every 12 months. Use the correct grade of oil when refilling. The gauze filter fitted to the air filter/filler cap unit may restrict fast filling but it is there to protect the reservoir and should not be removed or damaged to affect its function.

5. Do not top up the reservoir with a different brand of oil to that already

in use. Although the new oil may be quite suitable on its own, the inhibitors it contains may not mix with those in the oil in use.

23

6. Store all new oil in sealed containers away from extreme temperatures. Open containers will quickly collect dirt and dust and oil. Contaminated oil will rapidly choke the filter.

7. Do not use dirty oil the system. Filters will choke rapidly and oil will not

circulate satisfactorily. 8. Do not run the system with the air cleaner off the oil reservoir. 9. Do not attempt to clean out the reservoir using cotton waste or any similar

material. Lint material will inevitably cause sticking valves.

10. When operating in steamy or humid atmospheres, pipe the breather through partitions or walls to a clean dry place. This will help considerably to keep moisture from the oil.

B. OIL FILTER

However carefully the oil is stored and handled, there is still the possibility that contamination may find their way into the hydraulic system. The oil filter is therefore a most important part of the installation as it is the sole protection against contamination reaching finely adjusted precision equipment. A badly choked filter will cause noisy running and possible a seizure. Therefore the following maintenance should be observed.

The circuit diagram (GE-14116H-01) should be read to ascertain if an `in line' micro filter is fitted. This filter should be checked at intervals not exceeding three months. The paper element types should have a new element fitted.

C. PIPES

Minor troubles sometimes encountered in hydraulic systems may be easily avoided by careful attention to the fitting of the intermediate pipe work.

D. HOSE MAINTENANCE

Maintenance of the pipe system is extremely simple. The following points should be noted.

1. Make regular inspections of all hoses to ensure that no leaks are present. 2. Examine flexible hoses for signs of damage and deterioration. After

prolonged use, especially in hot atmospheres, leaks may occur around the ends of the pipes.

24

E. GENERAL MAINTENANCE AND OPERATION

1. Examine all external oil seals periodically. Remove and replace defective seals, as necessary.

2. Adjustment of the pump pressure is carried out by alteration of the setting

on the relief valve. Instructions for this are given on the appropriate data sheet. However, once the operating pump pressure has been set on initial commissioning, further adjustment is unnecessary.

3. Check the mountings of all units at regular intervals. All units must be secure,

especially those in high pressure systems. Check valve end caps. 4. Do not operate units at pressures greater than those recommended. 5. In the event of a breakdown, attempt to trace the fault, starting from the pump

and working outwards. Do not dismantle the system indiscriminately. 6. Do not use cotton waste or similar material to clean any part of a system.

Once cotton waste has been introduced into a system, numerous troubles will occur.

7. Handle all hydraulic equipment with care. Many parts are precision

manufactured to very fine limits and rough handling will cause damage. 8. Protect the piston rods of cylinders whilst maintenance is in progress.

Damage to piston rods will mean damage to wiper and internal seals causing leakage and loss of efficiency.

F. AIR IN THE SYSTEM Smooth action within a hydraulic system is ensured to a large degree by the incompressibility of the oil. This incompressibility is severely impaired when air or nitrogen from accumulators enters the system and irregular action of valves and cylinders accompanied by chattering and vibration will result. Air in the system may also seriously affect the performance and durability of the oil. Even though the general temperature of the oil does not show an excessive rise, local oxidisation may take place. This usually occurs as air enters the pump. Here it is compressed from normal atmospheric pressure to the outlet pressure of the pump and particularly when present as large bubbles, undergoes rapid increase in temperature. Oil surrounding each air bubble may be subjected to a temperature peak of up to 1110°C and becomes badly scorched and oxidised even though the size of the bubbles are such that a rise in temperature of the total oil content is not obvious. Oxidisation of this type is cumulative and eventually will affect the whole system.

25

To rid the system of air, trace the point at which the air is entering. It is no use ridding the system of air before this is done. On a new or recently dismantled system this precaution is usually unnecessary since air will have entered at the point where the units were removed. When air is entering a system inadvertently, it is usually through small holes in suction lines or packing glands. However, there are other ways by which air may enter as follows: -

a) Too low oil level in the reservoir permits air to be drawn into the pump section.

b) Low oil level in the reservoir, permitting returning oil to cascade into

reservoir. Air may mix in the falling oil and be drawn back into the system particularly if a rapid flow is used with a fairly small tank.

c) Loose joint connections on pump suction pipe d) By pouring oil into the tank too quickly when topping up. Slow

pouring will prevent an oil / air mix. e) If an accumulator is fitted, check for nitrogen leaks (as covered in

accumulator section). Change seals as required and proceed as above to rid the system of nitrogen.

In general, a good air-tight system, correct oil level and submerged oil lines will prevent the ingress of air. Bleeding need then only take place when a complete oil change is carried out or when units are installed, replaced or partially dismantled in-situ as part of general maintenance. G. BLEEDING THE SYSTEM (SEE SECTION 4 INSTALLATION & COMMISSIONING)

It is not possible in general terms to give instructions regarding the bleeding of the system as this must differ according to the type of circuit involved, the accessibility of equipment and numerous other factors. Detailed instructions regarding the bleeding at the time of installation complete with any other special recommendations for that equipment.

As a general guide, the main bleed points are at the highest point in the circuit BLEEDING AIR FROM CYLINDERS

If a hydraulic cylinder has been replaced after the cylinder is connected in the circuit, it should be bled of air. With the pipe connection tight, reciprocate three of four times by operating its reversing valve in separate air and oil. Slacken flexible pipe connection,

26

actuate cylinder until bubbling ceases and only oil is emitted, then with piston rod fully extended, re-tighten pipe connection.

BLEEDING AIR FROM PUMPS

If any of the following actions have been undertaken the pumps must be bled of air:-

a) A pump has been replaced

b) Oil has been total drained from the reservoir

c) The pump suction pipe has been removed or replaced

Follow the procedure in numerical order

1. ENSURE THE PUMP SUCTION VALVES ARE OPEN

3. WHEN AIR HAS BEEN RELEASED AND A CONSTANT FLOW OF FLUID EXISTS TIGHTEN THE BLEED SCREW

2. SLACKEN THE BLEED SCREW ON PUMP 7 TO ALLOW AIR TO BE

RELEASED

27

H. IN THE EVENT OF A BREAKDOWN

Check the circuit systematically, starting from the pump. Do not remove valves haphazardly. Do not attempt to remove units, etc. with the pump running or oil is either fully discharged from or isolated in, the accumulator. Pumps and Motors 1. Cut off oil supply, disconnect all pipe connections and catch fluid. 2. Disconnect drive, take out all mounting bolts and remove unit from circuit.

Cylinders 1. Cut off the oil supply, disconnect the pipe connection and catch fluid. 2. Uncouple the piston rod, remove the mounting bolts, and withdraw the

cylinder from the circuit.

3. Drain the oil through the ports.

Valves 1. Ensure that the pump drive is switched off and where possible, turn off oil

supply. 2. Disconnect all pipes and catch escaping oil. 3. Plug open pipes to prevent ingress of dirt. Do not use fluffy materials. 4. Take out mounting bolts and remove from circuit.

Reverse this procedure when replacing valve.

28

Servicing 1. Examine all seal rings for hardness, cracks or chipping and renew as

necessary. 2. Blow out all ports and drilling with compressed air. 3. Check all threaded parts for stripped threads. 4. Soak all metal parts in an approved solvent. 5. All traces of solvent must be removed prior to re-assembly,

preferably using clean, dry compressed air.

Re-Installation Careful re-installation of all units removed for servicing is of utmost importance. All parts must be clean and free from foreign matter. Other points to watch are: -

Bolt all units firmly in position before testing system. This applies specially to hydraulic cylinders. I. SUMMARY

It must be emphasised that this Section is only a General Guide to the maintenance of Hydraulic Systems. There are obviously many common-sense precautions that have not been covered and occasionally faults may arise as the result of a series of events that could not be foreseen.

29

7, FAULT LOCATION AND RECTIFICATION

CAUSES REMEDIES (a) NOISY PUMP AND/OR VALVES

1 The suction of the pump is restricted and causes cavitation in the pump.

Remove restrictions

2 The suction line is too small or the oil has too high a viscosity at the actual temperature. The friction losses in the suction line cause too high vacuum in the pump and cavitation.

The suction line should be changed to a larger size. Change the Oil. Cold oil is heated to normal temperature.

The oil is mixed with air. Air can be introduced into the system due to:- Leakage in the suction line. Too low oil in the oil reservoir. Return lines not submerged under the oil level and is spraying in a free jet into the tank. Leaking seals, etc. in the pressure line to components which are sometimes under vacuum due to location high above the oil tank

The piping and connections are inspected & tightened. Adding more oil to the reservoir The return lines are extended under the oil level. Check for air leakage, sometimes it might be necessary to place the oil reservoir higher than all components in the system in order to have the complete system under over-pressure.

4 Mechanical errors due to: - Faulty alignment of the pump in relation to the driving shaft (electric motor) Damaged shaft couplings or worn coupling belts or carriers. Worn pump. Vibrating pipes

Improve the alignment Replace damaged components Fasten the pipes

5 The pump and/or the driving motor is not as noiseless as necessary or the speed is not correctly chosen.

Replace pump or motor or change the speed

6 Oil is mixed with nitrogen that has entered the circuit due to faulty seals in the accumulator

Check seals on the accumulator. Replace if necessary

7 Worn cone or cone seat on the pressure control valve. This can cause the valve to be noisy or erratic.

Check cone and cone seat, replace where necessary

30

CAUSES REMEDIES (b) NO PRESSURE OR PRESSURE TOO LOW IN SYSTEM

1 The pump will not prime. See (a) para. 1 & 2 2 The relief valve is opening at too low

pressure due to wrong setting, too weak spring.

Adjust the setting of the valve. If possible check the pressure gauge at the same time or change the relief valve spring

3 The oil can pass from the pressure side to return line through some open passage, for instance, in an incorrect directional valve etc. The error can be caused by faulty valve impurities prohibiting the movement of the Piston in the valve, incorrect assembling of valves etc

Study the circuit diagram and follow all possible passages of oil. Check the type of valves which are assembled and position of the pistons. Run one section after the other in order to locate the error.

4 Damaged piston packing causing internal leakage of the cylinder.

Check by opening the connection at the return side of the cylinder. Replace packing if signs of leakage.

5 Worn pump which will not give sufficient capacity especially at low viscosity, eg. at high temperature of the oil

Repair or replace pump

6 Electric motor will not give full torque due to under-rating or incorrect connection (Star Connection instead of Delta)

Check the power of the electric motor and examine the electric connection.

(c) FLUCTUATING PRESSURE, FLOW, AND VIBRATION 1 The oil is mixed with air causing

fluctuating delivery from the pump or vibrating bypass valve

See (a) para 3. The oil in the reservoir must be clear without bubbles or foam.

2 The relief valve has no vibration damping devices.

Replace the valve with another type where constant pressure is essential

3 The design of the pump will cause variation in delivery

The pump is replaced against another type when smooth movements are essential

4 Speed control valves or throttles clogged by dirt, etc. causing uneven flow.

Clean and adjust valves

5 Air pockets in cylinder pipes, etc. causing pistons to bounce or jerk in operation

Remove air from system

6 Cones and cone seats damaged on pressure control valves

See (a) para 7.

31

CAUSES REMEDIES (d) PUMP DELIVERS NO FLUID

1 Low fluid level in reservoir Add more oil after examining causes of the loss of oil

2 The suction line is closed. See (a) para 1. 3 The pump is not running due to incorrect

assembly of the coupling Adjust coupling

4 The pump is running in a reversed direction or at incorrect speed

Check direction of rotation and speed

5 The viscosity of the oil is too high for the pump type that is used

See (a) para 2.

(e) EXCESSIVE HEATING OF OIL 1 The pressure setting of the relief/bypass

valve is too high. The valve is adjusted to a pressure just above that required

2 Bypassing at high pressure is occurring unnecessarily, for instance when the piston and the pump should be unloaded it is producing useful work. The cause can be that the directional valve has not got the correct neutral position or is wrongly situated.

Check that the pump is unloaded when no pressure is wanted. Adjust valves and instruct personnel how to run the system.

3 The unloading valve in an accumulator system is blocked. The pump is working continuously against the bypass valve when no oil is wanted in the system.

Adjust the unloading valve

4 Internal leakage. Main flow is passing from pressure side to reverse without doing any useful mechanical work

Examine the cause of the leakage and remedy this by replacing worn parts in pumps, valves or seals. Check cylinder hoses for uneven heat distribution – showing faulty piston head seals.

(f) FAILURE OF SOLENOID VALVE OR VALVE FUNCTIONS INCORRECTLY 1 Burnt out solenoid Replace coil. Check electrically:

a) Correct coil for voltage supply b) check that only one solenoid is energised at any time with spring centred, double solenoid valves Ensure strike pin & spool are free in both directions. Check for excess back pressure in tank port, correct circuit piping or valve mounted incorrectly on sub-plate.

2 Sticking piston Clean valve, paying particular attention

32

to spool, striker, & pins. Check solenoid is not tight on location pins.

3 Electrical failure Test by operating valve manually. Check as in 1(a) and (b) above

4 Valve will not operate manually Check circuit for correct piping. Check valve porting relative to base plate. Check if pipe restriction or fault causes high back pressure in return line.

8. SPECIFIC MAINTENANCE INSTRUCTIONS Maintenance Checks

Check Fluid level - weekly Visual inspection – 3 monthly • Check for leakage from the power pack and connections.

• Check the electrical connections.

• Visually inspect the cylinders and piston rods for damage.

• Check and replace as required pressure and return line filter elements

• Change over the duty pump. I.E. If pump 1 is the duty pump stop it and

start pump 2. This shares the work load on the pumps Functionality Check - 12 monthly or after not operating for 3 months • Check operation of all devices in line with operational instructions. • Check system pressures as detailed in Section 2.

• Drain hydraulic fluid from the reservoir.

• Clean out the reservoir internally

• Clean or replace pump suction strainer

• Re-fill with clean oil

• Replace Pressure Filter elements in Filters (11)

• Check the pre-charge pressure in the Accumulators (21)

(See Section 5 Settings and Adjustments for details of the procedure) Maintenance Before working on any actuator ensure that the Control Panel is isolated and that it is not operating

After 12 months, unless otherwise specified, the oil should be changed. We also recommend that at the same time, the dynamic seals and `O' rings are replaced.
