put and overheating. Spark arrestor screen must be checked
periodically. Clean deposits from silencer.

your dealer.
 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.
1. Check plug gap. Correct gap is 0.6 mm to 0.7 mm.

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