Carburettor adjustment
When carburettor adjustment is completed, attachment should not move at idle, otherwise serious personal injury may
result.
When starting, idle speed adjuster (T) should be adjusted not to rotate the attachment.
When there is some trouble with the carburettor, contact your dealer.

Cooling system maintenance
IMPORTANT
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,
or
Dust and grass build up on the out side 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.

Maintenance and care
Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start en-
gine and run several minutes to bring it to operating temperature.
To adjust the carburettor proceed as follow:
Turn "idle" speed adjustment screw (T) clockwise until atttach-
ment begins to turn, then turn screw(T) out anticlockwise until
attachment stops turning. Turn screw (T) out, anticlockwise,
and additional 1 turn.
Remove dust and dirt from between fins.
Before each use, remove accumulated debris from bottom en-
gine intake grille located between the fuel tank and starter.
