Adding Water to the Battery
Under normal operating conditions the battery fluid lev-
els may become lower. To bring the fluid up to the
required level, add distilled water.
1. Clean the top of the battery and remove the filler
caps.
2. Inspect each cell to determine the fluid level. The
level should be even with the bottom of the fill
tubes.
3. Add distilled water to each cell as needed.
4. Replace the filler caps. Clean up spills with water
and paper towels.
Measuring Specific Gravity
Using a hydrometer, measure the specific gravity of the
electrolyte in each cell. When the reading is below
1.2 at 68
o
F (20
o
C), recharge the battery.
4.24 CHARGE BATTERY
IMPORTANT: Always keep the battery charged
(1.26 specific gravity) to prevent battery damage when
the temperature is below 32
o
F (0
o
C).
1. Before charging, check the electrolyte level, refer to
Checking Electrolyte Level.
2. Follow the charger manufacturer’s instructions for
safe procedures. It is advisable that the battery be
charged as slowly as possible since quick charging
will shorten the battery service life. When the
battery has to be charged quickly, the charging
current should be held to 2.0A maximum.
3. Connect the battery charger to the battery posts.
Do not overcharge the battery.
4. After charging, flush the outside of the battery with
water.
4.25 REPLACING FUEL FILTER- GASOLINE
Replace the fuel filter once each year or after every 200
operating hours whichever occurs first. Never install a
dirty filter.
1. Lower the lift arms and stop the engine.
2. Clamp the fuel line to block fuel flow to filter.
3. Remove the hose clamps and slide them away
from the filter.
4. Place a drain pan under the fuel filter to catch any
drips and remove the filter.
5. Install a new filter and reattach the hoses. Move
the hose clamps close to the filter.
6. Un-clamp the fuel line.
4.26 CLEAN FUEL FILTER-DIESEL
Check and completely clean the fuel filter with clean
fuel oil if it is contaminated with deposits, water, etc.
The filter element should be replaced every 500 ser-
vice hours, or sooner if it is stained or broken. If the fuel
appears to be contaminated, check the filter carefully
and replace it even if the maximum number of service
hours has not been reached.
1. Close the fuel filter.
2. Remove the top cap and rinse the inside with
diesel fuel.
3. Remove the element and rinse it with diesel fuel.
4. After cleaning, reinstall the fuel filter.
5. The filter is equipped with an automatic vent. any
air in the fuel system will be pumped out through a
check valve in the top of the fuel filter.
WARNING: FROZEN BATTERIES CAN
EXPLODE and result in death or serious
injury.
DO NOT charge a frozen battery. Let the
battery thaw out before putting on a charger.
Clean inside filter Every 300 hours
100 hours (First
time)
Replace filter
