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 5/8” (16 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.
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.
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
Do not turn over the engine if the spark plug or ignition cable has been removed.
Fuses
The main fuse is placed in a detachable holder under the battery case’s cover, in front of the battery.
Type: Flat pin, 15 A.
Do not use any other type of fuse when replacing.
A blown fuse is indicated by a burnt connector. Pull the fuse from the holder when replacing.
The fuse is there to protect the electrical system. If it blows again shortly after replacement, it is due to a short circuit, which must be fixed before the machine can be put into operation again.
