Maintenance and care

Replacing fuel filter

Carburettor adjustment

When the carburettor is being adjusted, the cutting attachment may move. Be careful not to get injured.
When starting, idle speed adjustment screw (T) should be adjusted not to rotate the cutting attachment.
When there is some trouble with the carburettor, contact your dealer.
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.
1. Use a piece of metal wire or the like to pick up fuel filter (A)
through fuel tank opening.
2. Pull old filter from fuel line (B).
3. Install new fuel filter.
If filter is excessive dirty or no longer fits properly, replace it.
WARNING
CAUTION
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:
Start engine and turn "idle" speed adjustment screw clock-
wise until the cutting attachment begins to turn, then turn
the screw anticlockwise until the cutting attachment stops
turning. Turn screw anticlockwise an additional 1/4 turn.
Accelerate to full throttle for 2 to 3 seconds to clear excess
fuel from engine then return to idle. Accelerate to full throt-
tle to check for smooth transition from idle to full throttle.
