ADJUSTING THE CARBURETOR
See Figures 62 - 64.
Before adjusting the carburetor:

Use a brush or compressed air to clean the starter cover
vents.
 Clean the air cleaner. Refer to Cleaning the Air Cleaner
in the Maintenance section of this manual.
 Allow the engine to warm up prior to adjustment of engine
idle speed.
WARNING:
Weather conditions and altitude may affect carburetion.
Do not allow bystanders close to the chain saw while
adjusting the carburetor.
Idle Speed Adjustment —The idle speed adjustment controls
how much the throttle valve stays open when the throttle
trigger is released. To adjust:

Turn idle speed screw “T” clockwise to increase idle
speed.
 Turn idle speed screw “T” counterclockwise to decrease
idle speed.
 Make a test cut, then adjust the H needle for best cutting
power, not for maximum speed. The H needle is restricted
to 1/4 turn.
WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT IDLE.
Serious personal injury may result from the saw chain
turning at idle.
CLEANING THE STARTER UNIT
See Figure 63.
Use a brush or compressed air to keep the cooling vents of
the starter assembly free and clean of debris.
