QUARTERLY MAINTENANCE

(Every 250 Hours of Operation)
Check drive, vacuum and brush motors for carbon
brush wear, replace brushes if worn to a length of
10mm (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 or battery cables. Avoid contact
with battery acid.
1. Always follow proper charging instructions
(see CHARGING BATTERIES).
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 44).
FIG. 44
3. After charging batteries, measure the specific
gravity in each battery cell using a hydrometer
(Figure 45). 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.
