NOT USE .10W40 OIL. Refill capacity is 3 pints. NOTE:
DO
NOT OVERFILL.
FREQUENTLY
1. CHECK BATTERY
a. Electrolyte solution leve l in each Battery Cell should be
even with bottoms of tubes in cells (Fig. 19). Add dis-
tilled water if necessary. NOTE: DO NOT OVERFILL.
b. Keep Battery and Terminals clean. Refer to page 12,
step 6.
c. Keep Battery Bolts tight.
d. Keep
