CARBURETTOR ADJUSTMENT
WARNING
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
•

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 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.
•
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.
