See Figure 1.2 for the location of the air cleaner. Use
the following procedure (Figure 4.7):
1. Lift the roof and remove the door.
2. Turn the worm gear clamp screw counterclock-
wise to loosen.
3. Pull the old filter off the divider panel hub.
4. Wipe away dust or debris from the panel hub.
5. Install the new air cleaner onto the hub.
6. Turn the worm gear clamp screw clockwise to
tighten.
7. Replace door and roof.

4.5 SPARK PLUG(S)
Reset the spark plug(s) gap or replace the spark
plug(s) as necessary. See the Service Schedule section
for maintenance requirements.
1. Clean the area around the base of the spark
plug(s) to keep dirt and debris out of the engine.
2. Remove the spark plug(s) and check the condi-
tion. Replace the spark plug(s) if worn or if reuse
is questionable. See the Service Schedule section
for recommended inspection. Clean by scraping
or washing using a wire brush and commercial
solvent. Do not blast the spark plug(s) to clean.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.76 mm (0.030 inch)
for 7 and 10kW; and 1.02 mm (0.040 inch) for
13, 16 and 18kW by carefully bending the ground
electrode (Figure 4.9).

4.6 BATTERY MAINTENANCE
The battery should be inspected per the "Service
Schedule" section. The following procedure should be
followed for inspection:
1. Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
3. Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding.
A battery presents a risk of electrical shock
and high short circuit current. The following pre-
cautions are to be observed when working on
batteries:
