d. Remove filler caps.
WARNING
CAUSTIC CHEMICALS IN BATTERIES
Severe bums or blindness may result if battery electrolyte comes in contact with skin or eyes.
Rinse skin and eyes thoroughly with cold water if in contact with electrolyte.
BATTERIES GENERATE FLAMMABLE GAS
· Leave battery vent plugs installed while battery is being charged.
· Charge battery in a well-ventilated area.
· Do not smoke or use open flame or spark-producing equipment in the vicinity of charging
battery.
NOTE
Use an electrolyte with a specific gravity of 1.280. Do not use a tropical electrolyte which will lower the
batter reserve capacity.
e. If batteries are dry add electrolyte to each cell. Fill until level is above battery plates and reaches split ring in
filler neck.
f. Install filler caps.
g. Charge batteries fully.
h. Check that interior of battery box is clean. Be sure drain holes are open and not painted closed.
i. Place batteries into battery box. Orient terminals as shown.
j. Clean terminal clamps of cables.
CAUTION
Be sure that during installation the batteries are installed and connected in parallel. If batteries are not
connected in parallel, damage to starter and controls may occur.
k. Connect positive battery cable assembly to positive (+) battery terminals. Position grommet in cutout of battery
box. Tighten terminals securely.
l. Connect ground battery cable assembly to negative (-) battery terminals. Position grommet in cutout of battery
box. Tighten terminals securely.
m. Lightly coat both terminals and clamps with M1L-G-10924 grease.
