Servicing the Battery

Service Interval: Every 100 hours—Check the battery
electrolyte level (replacement battery
only).
Every 100 hours—Check the battery
cable connections.
Warning
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Important: The following procedures apply when
servicing a (dry) battery that has replaced the
original battery. The original (wet) battery does not
require service.
Always keep the battery clean and fully charged. Use
a paper towel to clean the battery case. If the battery
terminals are corroded, clean them with a solution of
four parts water and one part baking soda. Apply a light
coating of grease to the battery terminals to reduce
corrosion.
Voltage: 12 v, 585 Cold Cranking Amps
Checking the Electrolyte Level
1. Stop the engine and remove the key.
2. Remove the 4 bolts securing the battery cover and
remove it from over the battery.
3. Look at the side of the battery. The electrolyte must
be up to the Upper line (Figure 37). Do not allow the
electrolyte to fall below the Lower line (Figure 37).

4. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery.
Adding Water to the Battery
The best time to add distilled water to the battery is just
before you operate the traction unit. This lets the water
mix thoroughly with the electrolyte solution.
Battery electrolyte contains sulfuric acid which
is a deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact
with skin, eyes or clothing. Wear safety
glasses to shield your eyes and rubber gloves
to protect your hands.
• Fill the battery where clean water is always
available for flushing the skin.
1. Remove the battery from the traction unit.
Important: Never fill the battery with distilled
water while the battery is installed in the traction
unit. Electrolyte could be spilled on other parts
and cause corrosion.
2. Clean the top of the battery with a paper towel.
3. Remove the filler caps from the battery (Figure 37).
4. Slowly pour distilled water into each battery cell
until the electrolyte level is up to the Upper line
(Figure 37) on the battery case.
Important: Do not overfill the battery because
electrolyte (sulfuric acid) can cause severe
corrosion and damage to the chassis.
5. Wait five to ten minutes after filling the battery cells.
Add distilled water, if necessary, until the electrolyte
