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: 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 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).

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.
NOTE: Do not take reading immediately after adding
distilled water. The water and acid must be thoroughly
mixed in order for accurate reading.

NOTE: Add or subtract 0.004 gravity reading for each
6_C (10_F) above or below 27_C (80_F).
4. Keep battery tops and terminals clean and dry.
a. Mix a strong solution of baking soda and water
(Figure 41).
