2. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery,
below.
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.
1. Clean the top of the battery with a paper towel.
2. Lift off the filler caps (Fig. 49).
3. Slowly pour distilled water into each battery cell until
the level is up to the lower part of the tube (Fig. 49).
Important Do not overfill the battery because
electrolyte (sulfuric acid) can cause severe corrosion and
damage to the chassis.
4. Press the filler caps onto the battery.
Charging the Battery
Important
Always keep the battery fully charged
(1.260 specific gravity). This is especially important to
prevent battery damage when the temperature is below
32°F (0°C).
1. Check the electrolyte level; refer to Checking
Electrolyte Level, page 36.
2. Remove the filler caps from the battery and connect a
battery charger to the battery posts (Fig. 1). Charge the
battery at a rate of 6 to 10 amperes for a minimum of
1 hour (12 volts).
3. Install the filler caps after the battery is fully charged.

Charging the battery produces gases that can
explode.
Never smoke near the battery and keep sparks
and flames away from battery.

Cleaning the Chassis

Over time, the chassis under the engine collects dirt and
debris that must be removed. Using a flashlight, open the
hood and inspect the area under the engine on a regular
basis. When the debris is 1 to 2 inches deep, complete the
following procedure (refer to Figure 50 throughout this
procedure):

the two side weights, removing the weights (Fig. 50).
5. Open the rear access cover; refer to Opening the Rear
Access Cover, page 24.
6. Remove the three carriage bolts and washers from the
battery base and the fuel tank bracket, removing the
bracket (Fig. 50).
7. Remove the six nuts and bolts securing the rear panel,
removing the panel (Fig. 50).
