HOW IT WORKS

The Model 510E is a rider scrubber. The machineis propelled by a electric motor via the front wheel.The machine is steered with the steering wheeland is very responsive.

The main scrubbing components include asolution tank, two disc-type brushes, rear and sidesqueegees, a vacuum fan, and a recovery tank.

Water and detergent solution flows from thesolution tank through the water control valve tothe scrub brushes. The rotating scrub brushesscrub the floor. As the machine moves forward,the squeegees collect the dirty solution andchannel it into the vacuum of the squeegeepick-up hose. The pick-up hose deposits the dirtysolution in the recovery tank.

Machines with the ESt option filter the dirtysolution in the recovery tank and return it to thesolution tank.

RECOVERY TANK FULL INDICATOR

The recovery tank full indicator lights whenthe recovery tank is full.

HOUR METER

The hour meter records the number of hoursthe machine has operated. This information isuseful in determining when to service themachine.

BRUSH PRESSURE INDICATOR AND SWITCH

The brush pressure indicator shows thebrush pressure selection. The brush pressureswitch controls how aggressive the brushesare scrubbing the floor.

The brush pressure switch has four positions.Under normal conditions, the brush pressureshould be set in the light zone. Under heavy grimeconditions, the brush pressure should be set inthe heavy zones. Travel speed and floorconditions will affect the scrubbing performance.

ELECTRICAL SYSTEM

BATTERIES

The batteries provide all of the energy used by themachine. The standard batteries are rated at380 A/h at a 6-hour rate. The heavy duty batteriesare available as an option. They are rated at 570A/h at a 6-hour rate. The batteries require regularmaintenance to keep them operating their best.

Periodically clean the top surface and theterminals and check for loose connections. Use astrong solution of baking soda and water. Brushthe solution sparingly over the battery top,terminals, and cable clamps. Do not allow anybaking soda solution to enter the battery. Use awire brush to clean the terminal posts and thecable connectors. After cleaning, apply a coatingof clear petroleum jelly to the terminals and thecable connectors, Keep the tops of the batteriesclean and dry.

Check the electrolyte level in each battery cellbefore and after charging the batteries. Never addacid to the batteries, only distilled water. Do notoverfill. Keep vent plugs firmly in place at alltimes, except when adding water or takinghydrometer readings.

FOR SAFETY: When Servicing Machine, AvoidContact With Battery Acid.

Do not operate the machine if the batteries are inpoor condition or have a charge level below 25%,specific gravity below 1.177. Do not allow thebatteries to remain in discharged condition for anylength of time.

Keep all metallic objects off the top of thebatteries, as they may cause a short circuit.Replace worn or damaged wires.

The machine batteries are unique in that they holdtheir power of long periods of time, but they canonly be recharged a certain number of times. Toget the most life from the batteries, charge themwhen their charge level is below 25%. Todetermine the charge level, check the batteriesspecific gravity with a hydrometer.

CHECKING BATTERY SPECIFIC GRAVITY

A. HydrometerB. Battery

If one or more battery cells tests lower than theother battery cells, (0.050 or more) the cell isdamaged, shorted, or is about to fail.

NOTE: Do not take readings immediately afteradding water -- if the water and acid are notthoroughly mixed, the readings may not beaccurate. Check the hydrometer readings againstthe following chart:

Specific Gravity Batteryat 80_ F (27_ C) Condition

1.290 100% charged1.252 75% charged1.215 50% charged1.177 25% charged1.110 Discharged

NOTE: If the readings are taken when the batteryelectrolyte is any temperature other than 80_ F(27_ C), the reading must be temperaturecorrected.

MAINTENANCE

510E MM239 (3--91)3-8

To determine the corrected specific gravityreading when the temperature of the batteryelectrolyte is other than 80_ F (27_ C):

Add to the specific gravity reading 0.004(4 points) for each 10_ F (6_ C) above80_ F (27_ C).

Subtract from the specific gravity reading0.004 (4 points) for each 10_ F (6_ C) below80_ F (27_ C).

Eight to twelve hours is generally enough time tocharge a discharged set of batteries. If thebatteries are not fully discharged, charge for aperiod of time that is proportionally less than whatis required for a fully discharged set of batteries,ie; half discharged batteries need four to six hoursof charging time.

Do not expose the battery charger to water. Donot touch uninsulated battery terminals orunnecessarily expose any portion of your body tothe batteries when making electrical connections.

TO CHARGE BATTERIES

1. Stop the machine on a flat, dry surface nextto the charger and set the machine parkingbrake.


2. Turn the key-operated on-off switchcounter-clockwise to turn off the machine.

3. Lift open the machine cover.

WARNING: Batteries Emit HydrogenGas. Explosion Or Fire Can Result.

Keep Sparks And Open Flame Away. KeepCovers Open When Charging.

4. Remove the seat support.

5. Check the electrolyte level in the batteries.

Before charging, add just enough distilledwater to cover the plates. Then, aftercharging is completed, add enough water tobring the level up to the indicator ring. If thewater level is topped off before charging,normal expansion of the electrolyte maycause an overflow, resulting in loss of acidbalance and damage to the machine.

6. Replace the battery caps and leave them inplace while charging.

SCRUB HEAD

SCRUB HEAD

The scrub head houses the two disc type scrubbrushes, and their drive and lift mechanisms. Thescrub head is factory adjusted and themeasurement should not be changed unlessscrub head parts are damaged or are replaced.The scrub head has three adjustments --side-to-side centering, edge scrub switch, anddown pressure.

TO CENTER SCRUB HEAD

NOTE: The scrub head is factory adjusted andthe measurement should not be changed unlessscrub head parts are damaged or are replaced.

1. Stop the machine on a smooth, level floor.



3. Place a straight edge up against the mainframe and the edge of the scrub head onboth sides of the machine to measure forcentering from side to side. Side-to-sidecentering should measure equal on bothsides of the machine within 0.25 in (6 mm).

4. To adjust the centering, loosen the edgescrub actuator bracket mounting hardware.

SCRUB BRUSHES

Two disc-type scrub brushes scrub the floor. Eachscrub brush is driven by its own electric motorthrough a gearbox to a drive hub. A spring lockclip holds the scrub brush onto the drive hub.

There are many variations of brushes andcleaning pads to choose from. There is a brush orcleaning pad available for almost any application.Scrub brushes are ready for use when they areequipped with a brush drive plate and a springclip.

The scrub brushes should be checked daily fortangled wire or string wear damage. The scrubbrushes should be replaced if large portions of thebrush bristles are missing or if the remainingbrush bristle measure 0.25 in (6 mm) or less inlength.

NOTE: Be sure to replace the scrub brushes insets. Otherwise one scrub brush will be moreaggressive than the other.

TO REPLACE SCRUB BRUSHES
