6. Connect battery charger to machine as shown
(Fig. 34).
FOR DEEP CYCLE BATTERY CHARGING
NOTE: For optimum machine operation, keep
batteries charged at all times. Never leave batteries
discharged for lengthy periods.
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and
open flame away.
FOR SAFETY: When servicing machine, wear
hand and eye protection when handling batteries
and battery cables. Avoid contact with battery
acid.
1. Drive machine to a well–ventilated area for
charging.
Figure 34
2. Park machine on a level surface, turn key to the
off position and set parking brake.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, set parking brake,
turn off machine and remove key.
3. Hinge seat away from machine to access battery
compartment.
4. Check fluid level (A) in each battery cell before
charging. If battery plates (B) are exposed, add
just enough distilled water to cover plates by
approximately 3 mm (0.13 in). DO NOT
OVERFILL. Overfilled batteries will overflow
during charging due to fluid expansion. Replace
cell caps before charging (Fig. 32).
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and
open flame away.
NOTE: The machine becomes inoperable once
charger is connected.
7. Charger will automatically begin charging and shut
off when fully charged.
8. When disconnecting charger, always unplug
charger from wall outlet first.
9. After charging, check battery fluid level. Fluid level
should be within 3 mm (0.13 in) of full level
indicator. Add distilled water if needed. DO NOT
OVERFILL.

is located behind scrub head under machine.
Make sure solution tank is empty before removing
filter (Fig. 36).
DAILY MAINTENANCE
(Every 4 Hours of Use)
1. Drain and flush out tanks with clean water (See
DRAINING TANKS).
2. Remove and rinse float shut-off screen located in
recovery tank (Fig. 35).
Figure 36
2. Check fluid level in battery cells (See BATTERY
MAINTENANCE).
3. Clean battery tops to prevent corrosion (See
BATTERY MAINTENANCE).
4. Check for loose or corroded battery cables.
MONTHLY MAINTENANCE
(Every 80 Hours of Use)
Figure 35
3. Check brushes for entangled debris.
4. Change pads or brushes, replace if worn or
damaged (See REMOVING BRUSHES/PAD
DRIVERS).
5. Check scrub head skirt(s) for wear and adjustment.
6. Raise squeegee and wipe it down with a dry cloth.
Store squeegee in the up position to prevent
squeegee damage.
7. Check machine for water leaks and loose nuts and
bolts.
8. Clean machine housing with an all purpose

OPERATION
b. Brush solution sparingly over battery tops,
terminal and cable connectors.
QUARTERLY MAINTENANCE
(Every 250 Hours of Use)
1. Check drive transaxle, vacuum and brush motors
for carbon brush wear, replace brushes when worn
to a length of 10 mm (0.38 in) or less.
Contact an Authorized Service Center for motor
maintenance.
NOTE: Do not allow baking soda solution to enter
battery cells.
c. Use wire brush to clean terminal post and
cable connections.
d. After cleaning, apply a coating of clear battery
post protectant to terminals and cable
connections.
2. Check steering chain tension (See STEERING
CHAIN MAINTENANCE).
4. Check for loose or worn cables. Replace if worn.
BATTERY MAINTENANCE
STEERING CHAIN MAINTENANCE
The steering chain tension should be checked after
the first 50 hours of operation and every 250 hours
thereafter.
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and
open flame away.
FOR SAFETY: When servicing machine,
disconnect battery connections before working on
machine.
FOR SAFETY: When servicing machine, wear
hand and eye protection when handling batteries
and battery cables. Avoid contact with battery
acid.
1. To access steering chain, remove five floor panels,
13 mm wrench and Phillips head screwdriver
required (Fig. 39).
1. Always follow proper charging instructions (See
CHARGING BATTERIES).
2. After charging, check fluid level (A). Fluid level
should be within 3 mm (0.13 in) of full level
indicator. Add distilled water if needed. DO NOT
OVERFILL. Overfilled batteries will overflow
during charging due to fluid expansion (Fig. 37).
A
Figure 39
Figure 37
3. Keep battery tops and terminals clean and dry.
To clean batteries:
a. Mix a strong solution of baking soda and water
(Fig. 38).
2. Measure amount of chain deflection at location
shown below. Proper chain deflection should be
approximately 25 mm (1.00 in) total (Fig. 40).

OPERATION
3. To adjust chain tension, loosen jam nut on the idler
sprocket adjustment screw and turn screw
clockwise to increase tension. Retighten jam nut
after adjusting (Fig. 40).
4. Lubricate chain with a water resistant oil.
BRAKE ADJUSTMENT
If machine pulls in either direction while braking or if
machine does not stop immediately, brake adjustment
may by required.
FOR SAFETY: When servicing machine,
disconnect battery connections before working on
machine.
3. To adjust brakes, loosen jam nut and turn hex link
adjuster as described below:
RIGHT SIDE – Turn hex link adjuster clockwise to
increase or counter-clockwise to reduce brake
pressure.
LEFT SIDE – Turn hex link adjuster counter–
clockwise to increase or clockwise to reduce brake
pressure.
NOTE: Brake adjustment should be made so that
brake pads are loose; not rubbing disc. A .045” shim
should be used for proper adjustment between pad
and disc. Adjusting the brakes too tightly will create an
extra load on the drive system and cause overloading
problems.
1. Hinge open skirts to access brakes (Fig. 41).
JACKING MACHINE
Empty tanks prior to jacking. Stop machine on a flat
level surface and block machine tires before jacking
up machine.
Use designated location for jacking up machine. Use a
piece of wood to distribute machine weight (Fig. 43).
Figure 41
2. Locate hex link brake adjusters in front of each
drive wheel (Fig. 42).
Figure 43
FOR SAFETY: When servicing machine, block
machine tires before jacking machine up.
FOR SAFETY: When servicing machine, jack
machine up at designated locations only. Block
machine up with jack stands.
