MAINTENANCE
Checking of 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.
Check the level of the battery acid
Check that the level of the battery acid lies between
the markings. Top up the cells with only distilled
water.
IMPORTANT INFORMATION
Do not turn over the engine if the spark
plug or ignition cable has been removed.
WARNING!

External: Rinse well with plenty of water.
Internal: Drink large quantities of water or
milk. Contact a doctor as soon as
possible.

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 chapter
”Technical data”.
IMPORTANT INFORMATION
Fitting the wrong spark plug type can damage
the engine.
1. Remove the ignition cable shoe and clean
around the spark plug.
2. Remove the spark plug with a 5/8" (16 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 steel 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.
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. 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 1/8–1/4 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.
