3.Wipe away dust or debris from inside of the air box and around edges.

4.Install the new air cleaner into the air box.

5.Install the cover. Turn the two cover screws clock- wise to tighten.

See the “Service Schedule,” Section 4.13 for air cleaner maintenance. See Section 1.5.1 for air filter replacement part number.

2.Remove the spark plug(s) and check the condi- tion. Replace the spark plug(s) if worn or if reuse is questionable. See Section 4.13 for recommend- ed inspection.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.76 mm (0.030 inch) for 7 kW and 0.50 mm (0.020 inch) for 12/15 kW by carefully bending the ground electrode (Figure 4.8).

4.7BATTERY MAINTENANCE

The battery should be inspected per the “Service Schedule,” Section 4.13. 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 BATTER- IES.

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:

•Remove watches, rings or other metal objects;

•Use tools with insulated handles;
