MOTOR MAINTENANCE

Quarterly (Every 250 Hours) -- Check the drive
transaxle motor and vacuum motors for carbon brush
wear. Replace carbon brushes when worn to a length
of 10 mm or less.
Annually (Every 1000 Hours) -- Check the brush
motors for carbon brush wear. Replace carbon
brushes when worn to a length of 10 mm or less.
Contact an Authorized Service Center for
machine repairs.
FOR SAFETY: When servicing machine, all repairs
must be performed by a qualified service person.
WARNING: Electrical Shock Hazard.
Disconnect Battery Cables Before Servicing
Machine.

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 41). 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.

NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_C (80_F),
the reading must be temperature corrected. Add or
subtract to the specific gravity reading 0.004, 4 points,
for each 6_C (43_F)above or below 27_C (80_F).
2. Always follow proper charging instructions
(See CHARGING BATTERIES).
3. Check the electrolyte level (A) in each battery cell
after charging batteries. The level should be
approximately 1 cm (3/8") from the bottom of the
fill--port (B). Add distilled water if needed
(Figure 42). DO NOT OVERFILL.
