MONTHLY MAINTENANCE
(Every 80 Hours of Operation)
1. Lubricate wheel grease fittings with a water
resistant grease.
2. Lubricate all linkage pivot points with silicone
spray then coat with a water resistant grease to
maintain a smooth operation.
3. Check machine for water leaks and loose nuts and
bolts.
QUARTERLY MAINTENANCE
(Every 250 Hours of Operation)
Check motor(s) for carbon brush wear, replace
brushes if worn to a length of 10mm (0.38 in) or less.
Contact your Authorized Service Center for carbon
brush inspection.
FOR SAFETY: When servicing machine all repairs
must be performed by a qualified service person.
BATTERY MAINTENANCE
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 or battery cables. Avoid contact
with battery acid.
1. Always follow proper charging instructions (See
BATTERY CHARGING).
2. Check fluid level (A) in each battery cell. The fluid
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 39).
FIG. 39
3. After charging batteries, measure the specific
gravity in each battery cell using a hydrometer
(Figure 40). 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.

4. Keep battery tops and terminals clean and dry.
a. Mix a strong solution of baking soda and water
(Figure 41).

b. Brush solution sparingly over battery tops,
terminal and cable connectors.
NOTE: Do not allow baking soda solution to enter
