3. 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. 29).
3. Slowly pour distilled water into each battery cell until
the level is up to the lower part of the tube (Fig. 29).
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 27.
2. Remove the filler caps from the battery and connect a
3 to 4 amp battery charger to the battery posts. Charge
the battery at a rate of 4 amperes or less for 4 hours
(12 volts). Do not overcharge the battery.

Warning
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks
and flames away from battery.
3. Install the filler caps after the battery is fully charged.
4. Replace the battery cover.
Servicing the Hydraulic
System
Replacing the Hydraulic Filter
Change the hydraulic filter:
After the first 8 operating hours.
After every 400 operating hours.
1. Position traction unit on a level surface.
2. Raise the loader arms and install the cylinder locks;
refer to Using the Cylinder Locks,
page 20.
3. Stop the engine and remove the key.
4. Remove the front access cover, refer to Removing the
Front Access Cover, page 24.
Important Do not substitute an automotive oil filter or
severe hydraulic system damage may result.
5. Place a drain pan under the filter.
6. Remove the old filter and wipe the filter adapter,
gasket surface clean.
7. Apply a thin coat hydraulic fluid to the rubber gasket
on the replacement filter (Fig. 30).
8. Install the replacement hydraulic filter onto the filter
adapter. Tighten it clockwise until the rubber gasket
contacts the filter adapter, then tighten the filter an
additional 1/2 turn (Fig. 30).
9. Clean up any spilled fluid.
10. Start the engine and let it run for about two minutes to
purge air from the system.
11. Stop the engine and check for leaks.
