ADJUSTING THE CARBURETOR
See Figure 63 - 64.
WARNING:
The chain will move around the guide bar when
adjusting the idle speed. Wear all protective cloth-
ing and keep all bystanders, children, and pets at
least 50 ft. away. Make adjustments with the unit
supported on a stable surface so that the chain/
guide bar does not contact the ground or any
object. Keep all parts of your body away from the
chain/guide bar and muffler. Failure to follow these
instructions could result in serious personal injury.
Before adjusting the carburetor:
 Use a brush or compressed air to clean the starter
cover vents.
 Clean the air filter. Refer to Cleaning the Air Filter
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 carbu-
retion. 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.
WARNING:
THE SAW CHAIN SHOULD NEVER TURN AT
IDLE. Serious personal injury may result from the
saw chain turning at idle.
