MAINTENANCE

CLEANING THE SEDIMENT CUP

Close the fuel valve. Remove the cup [1] and the O-
ring [2] and wash them in a non-flammable solvent.
Dry them thoroughly and refit them. Open the fuel
valve and check that there is no fuel leakage.

SERVICING THE SPARK PLUG

Recommended sparking plugs:
BPR-6ES (NGK), W20EPR-U (NIPPONDENSO Co., Ltd.).
CAUTION :
• Only use the recommended type of spark plug.
• The use of plugs with an incorrect rating can cause damage to the engine.
If the engine has been running, do not touch the muffler or the spark plug as you risk
burning yourself.
1. Remove the cap and unscrew the spark plug using a spark plug spanner.
2. Examine the spark plug carefully, and replace it if there are thick deposits on the
electrodes or if the insulator is cracked or broken. Clean the spark plug with a wire brush.
3. Measure the gap between the electrodes with a set of feeler gauges: it
must be between 0.7 and 0.8 mm. If the gap has to be adjusted, bend
the side electrode carefully.
4. Check the state of the sealing washer, then thread the plug back in by
hand until it is hand-tight and seated properly.
5. Using a spark plug spanner, screw the plug in an extra 1/2 turn for a
new spark plug, to compress its washer, or between 1/8 and 1/4 turn in
the case of a plug being reused. Put the spark plug cap back on.
CAUTION :
• The spark plug must be properly tightened or else it is likely to overheat
considerably, causing damage to the engine.
