The battery emits explosive gases. Sparks,
flames, and cigarettes must not be present in
the vicinity of the battery.
Checking the Acid Level in the Battery
Check that the acid level in the battery lies between
the markings. When refilling, only distilled water
may be used to fill the cells.
Ignition System
The engine is equipped with an electronic ignition
system. Only the spark plugs require maintenance.
For the recommended spark plug, see Technical
data.
IMPORTANT INFORMATION
Fitting the wrong spark plug type can
damage the engine.
Replacing the Spark Plug
1. Remove the ignition cable shoe and clean
around the spark plug.
2. Remove the spark plug with a 3/4" (19 mm)
spark plug socket wrench.
3. Check 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 wire brush if it is to be reused.
4. Measure the electrode gap with a gapping tool.
The gap should be 0.75 mm / 0.030". Adjust as
necessary by bending the side electrode.
5. Reinsert the spark plug, turning by hand to
avoid damaging the threads.
6. After the spark plug is seated, tighten it using a
spark plug wrench 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 1/4 a turn from
the seated position.
7. Replace 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.
