Maintenance

6If the paper filter is still dirty it should be replaced with a new one.

Always replace the paper filter every 200 hours.

7Put the pre-filter and paper filter back into the air filter unit.

8Put back the air filter unit by first aligning the hooks on the bottom of the unit, then press it until the catches lock into position.

Checking the fuel pump’s air filter

Check regularly that the fuel pump’s air filter is free from dirt.

The filter can when necessary be cleaned with a brush.

Remove the screws and open the pump, no hoses need be removed.

Replace the pump on the console.

Ignition system

The engine is equipped with an electronic ignition system. Only the spark plug requires maintenance.

For recommended spark plug, see Technical data.

IMPORTANT INFORMATION

Fitting the wrong spark plug type can damage the engine.

Replacing the spark plug

1Remove the ignition cable shoe and clean around the spark plug.

2Remove the spark plug with a 3/4” (19 mm) spark plug socket wrench.

3Check the spark plug. Replace the spark plug if the electrodes are burned or if the insulation is cracked or damaged. Clean the spark plug with a steel brush if it is to be reused.

4Measure the electrode gap with a gapping tool. The gap should be 0.75 mm/0.030”. Adjust as necessary by bending the side electrode.

5Reinsert the spark plug, turning by hand to avoid damaging the threads.

6Tighten the spark plug, once it touches the seating, with the spark plug spanner. Tighten the spark plug so that the washer is compressed. A used spark plug should be turned 1/8 of a turn from the seated position. A new spark plug should be turned a 1/4 turn from the seated position.

7Replace the ignition cable shoe.

IMPORTANT INFORMATION

Inadequately tightened spark plugs can cause overheating and damage the engine. Tightening the spark plug too much can damage the threads in the cylinder head.
