Maintenance and care

Replacing fuel filter
Carburettor adjustment
YOU MAY ADJUST THE IDLE SPEED ONLY by turning the idle speed adjustment screw (T).
During carburettor adjustment, the cutting attachment may move. Pay utmost attention and care to the cutting at-
tachment so as not to get injured by the moving cutter.
When carburettor adjustment is completed, the cutting attachment should not move at idle speed, otherwise serious
personal injury may result.
You must NOT carry out any Carburettor adjustment, other than the idle speed. All other adjustments MUST be per-
formed by an authorized service dealer, or serious personal injury may result due to malfunction of the engine.
When there is trouble with the carburettor, contact an authorized service 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:
Turn "idle" speed adjustment screw (T) clockwise until cutting
attachment begins to turn, then turn screw(T) out anticlock-
wise until cutting attachment stops turning. Turn screw (T) out,
anticlockwise, and additional 1 turn.
NOTE
When the carburettor cannot be adjusted properly with the idle
speed adjustment screw (T), you must contact an authorized
service dealer.
