Maintenance

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.

Controlling the acid level in a dry- charged battery

Check that the level of the battery acid lies between the markings. When refilling, only distilled water may be used to fill the cells.

WARNING! Procedures on contact with acid

!

External: Rinse well with plenty of water.

Internal: Drink large quantities of water or milk. Contact a doctor as soon as possible.

Eyes: Rinse well with plenty of water.

Contact a doctor as soon as possible.

Batteries emit explosive gas. Sparks, flames and cigarettes must absolutely not be brought into the vicinity of the battery.

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.

Do not turn over the engine if the spark plug or ignition cable has been removed.
