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 Use)
Inspect motors for carbon brush wear. Replace
brushes when worn to a length of 10mm (0.38 in ) or
less. Contact an Authorized Service Center for carbon
brush inspection.
ATTENTION: Contact an Authorized Service
Center for machine repairs. Machine repairs
performed by other than an authorized person will
void the warranty.
BATTERY MAINTENANCE
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing machine, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
1. Check the specific gravity using a hydrometer to
determine the charge level and the condition of the
batteries (Figure 25). If one or more of the battery
cells read lower than the other battery cells (0.050
or more), the cell is damaged, shorted, or is about
to fail. Check the hydrometer readings against the
following chart to determine the remaining battery
charge level.
NOTE: Do not take readings immediately after adding
distilled water. If the water and acid are not thoroughly
mixed, the readings may not be accurate.
