Replacing the spark plug
1. Remove the ignition cable shoe and clean around
the spark plug.
2. Remove the spark plug with a 13/16" (21 mm)
spark plug socket wrench.
3. Check the spark plug.
Replace the spark plug if the electrodes are burnt
or if the insulation is cracked or damaged.
Clean the spark plug with a wire brush if it is to be
reused.
4. Measure the electrode gap with a gapping tool.
The gap should be 0.7 - 0.8 mm / 0.030". Adjust
as necessary by bending the side electrode.
5. Reinsert 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.
6. Tighten 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 1/8-1/4 of
a turn from the seated position. A new spark
plug should be turned 1/2 a turn from the seated
position.
7. Replace the ignition cable shoe.

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.
The fuse for the power outlet is placed under the
ignition switch, behind the side plate on the control
panel.
Type: Flat pin, 7.5 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.
