Maintenance and care
 Keep dirt away from engine and air intake grid.
Cleaning silencer
 Carbon deposits in silencer (A) will cause a drop in engine out-
put and overheating. Clean deposits from silencer.
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.

in the ceramics, replace them with new parts. (see Specifi-
cationspage 28)
