Cooling system maintenance
 To maintain proper engine operating temperature, cooling air must pass freely through the cylinder fin area. This
flow of air carries combustion heat away from the engine. Overheating and engine seizure can occur when:
 Air intakes are blocked, preventing cooling air from reaching the cylinder.
 Dust and grass build up on the outside of the cylinder. This build-up insulates the engine and prevents the heat
from leaving.
Removal of cooling passage blockages or cleaning of cylinder fins is considered "Normal Maintenance". Any resultant failure
attributed to lack of maintenance is not warranted.
Cleaning silencer
Check fuel system
Check spark plug
IMPORTANT
Air intake
Maintenance and care
 Remove dust and dirt from between fins (A).
 Before each use, remove accumulated debris from bottom en-
gine intake grille located between the fuel tank and starter.
 Carbon deposits in silencer (A) will cause a drop in engine out-
put and overheating. Spark arrestor screen must be checked
periodically. Clean deposits from silencer.
IMPORTANT
Do not remove the silencer cover. If necessary, Please consult
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.
When remove the spark plug cap, pry it with using the socket
wrench.
