SERVICE AND ADJUSTMENTS
ADJUSTING PROCEDURE
IDLE SPEED ADJUSTMENT "T"
• Allow the warm engine to idle.
o Adjust the Idle Speed until the engine continues to run
without stalling and without the chain moving.
- Turn clockwise to increase engine speed ff engine
stalls or dies.
- Turn counterclockwise to slow engine down and/or to
keep the chain from turning.
• No further adjustments are necessary if chain does not
move at idle speed and if performance is satisfactory.
i_- LOW SPEED MIXTURE ADJUSTMENT"L"
° Allow engine to idle.
• Turn the Low Speed Mixture Adjustment slowly clock-
wise until the RPM starts to drop. Note the position.
° Turn the Low Speed Mixture Adjustment slowly counter-
clockwise unt_thb' RPM speeds up and starts to drop
again. Note th_ position.
• Set the Low Speed Mixture at the midpoint between the
two positions_-
HIGH SPEED MIXTURE ADJUSTMENT "H"
IMPORTANT: DO NOT OPERATEoENGINE AT FULL
THROTTLE FOR PROLONGED PERIODS WHILE MAK-
ING HIGH SPEED ADJUSTMENTS AS DAMAGE TO THE
ENGINE CAN OCCUR.
• Make a test cut.
• Based on performance of the saw while cutting, adjust
the high speed mixture in 1/16 turn increments as fol-
lows:
- Clockwise if saw loses power in the cut. Do not adjust
for best power by sound or speed, but judge by how
well the saw performs in the cut.
- Counterclockwise if the saw has speed while out of the
cut, but dies in the cut-o[ Jackspower while cutting.
• Repeat the test cut.
° Continue with 1t16 turn adjustments until the saw perfor-
mance is acceptable while cutting.
• Aftercompleting adjustments; check for acceleration.
ACCELERATION CHECK
* If the engine dies or hesitates instead of accelerating,
turn the Low Speed Mixture Adjustment 1/16 of a turn at
a time counterclockwise until you have smooth accelera-
tion.
• Check the idle speed for stability and no chain move-
ment: Adjust as necessary.
• Recheck for smooth acceleration and stable idle. RePeat
process as necessary for acceptable performance.
