CARBURETTOR ADJUSTMENT
WARNING DANGER
WHEN CARBURETTOR ADJUSTMENT IS COMPLETED, CUTTING ATTACHMENT SHOULD NOT MOVE AT IDLE, OTHERWISE SERIOUS PERSONAL INJURY MAY RESULT.
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 engine and run several minutes to bring it to operating temperature.
To adjust the carburettor proceed as follow:
1.Trun the low speed mixture adjuster (L) and high speed mixture adjuster (H) anticlockwise to stop.
2.Start engine and turn “idle” speed adjustment screw
(T)clockwise until the cutting attachment begins to turn, then turn the screw (T) anticlockwise until the cutting attachment stops turning. Turn screw (T) anticlockwise an additional 1/4 turn.
3.Accelerate to full throttle for 2 to 3 seconds to clear excess fuel from engine then return to idle. Accelerate to full throttle to check for smooth transition from idle to full throttle.
CAUTION
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.
REPLACING FUEL FILTER
•Use a piece of steel 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.

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
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.
•Remove dust and dirt from between fins.
•Before each use, remove accumulated debris from bottom engine intake grille located between the fuel tank and starter.
