Maintenance and care
Check fuel system
Check before every use.
After refuelling, make sure fuel does not leak or exude from
around fuel pipe (A), fuel grommet (B) or fuel tank cap (C).
In case of fuel leakage or exudation, there is a danger of fire.
Stop using the machine immediately and request your dealer
to inspect or replace.
Check spark plug
1. Check plug gap. Correct gap is 0.6 mm to 0.7 mm.
2. Inspect electrode for wear.
3. Inspect insulator for oil or other deposits.
4. If the electrodes or terminals are worn, or if there are cracks
in the ceramics, replace them with new parts.
5. Tighten to 15 N·m - 17 N·m (150 kgf·cm to 170 kgf·cm).
The spark test (for checking whether the spark plug is spark-
ing) must be carried out by your dealer.
