Maintenance and care
Replacing fuel filter
1. Fuel filter
Carburettor adjustment
When carburettor adjustment is completed, cutting attachment should not move at idle, otherwise serious personal in-
jury may result.
When starting, idle speed adjuster (T) should be adjusted not to rotate the cutting attachment.
When there is some trouble with the carburettor, contact your dealer.
T: Idle speed adjustment screw
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.
2. Fuel line
WARNING
CAUTION
Use a piece of metal wire or the like to pick up fuel filter
through fuel tank opening.
Pull old filter from fuel line.
Install new fuel filter.
NOTE
If filter is excessive dirty or no longer fits properly, replace it.
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 cutting
atttachment begins to turn, then turn screw(T) out anticlock-
wise until cutting attachment stops turning. Turn screw (T)
out, anticlockwise, and additional 1 turn.
