3. Lubricate the caster grease fittings with a water
resistant grease (Figure 35).

4. Lubricate all pivot points and rollers with silicone
spray then coat with a water resistant grease to
maintain smooth operation.
5. Check the machine for water leaks and loose nuts
and bolts.

QUARTERLY MAINTENANCE

(Every 250 Hours of Use)
Check the 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 carbon
brush inspection.
FOR SAFETY: When servicing machine, all repairs
must be performed by a qualified service person.

BATTERY MAINTENANCE

The lifetime of the batteries is limited by the number of
charges the batteries receive. To get the most life from
the batteries, maintain the proper level of electrolyte
and only recharge when discharged more than 15% of
battery capacity.
WARNING: Keep Sparks And Open Flame
Away. Keep Battery Hood Open When Charging.
FOR SAFETY: When servicing machine, wear
protective gloves and safety glasses when
handling batteries and battery cables. Avoid
contact with battery acid.
1. Always follow proper charging instructions (See
CHARGING BATTERIES).

2. Check the electrolyte level (A) in each battery cell.
The level should be 1 cm (3/8 in) from the bottom
of sight tubes after charging. Add distilled water if
needed. DO NOT OVERFILL. Overfilled batteries
can overflow during charging due to fluid
expansion (Figure 36).

3. After charging batteries, measure the specific
gravity in each battery cell using a hydrometer
(Figure 37). This will determine the charge level
and condition of the batteries. If one or more of
the battery cells test lower than the other battery
cell (0.050 or more), the cell is damaged,
shortened, or is about to fail.
NOTE: Do not take reading immediately after adding
distilled water. The water and acid must be thoroughly
mixed in order for accurate reading.
