To adjust the high speed needle (H)
The engine is adjusted at the factory to operate at sea
level. At higher altitudes, in different weather or different
temperatures it can be necessary to adjust the high
speed needle.
• Turn the high speed needle to make adjustments.
CAUTION: Do not turn the high speed
needle screw across the adjustment
limitation stop. This can cause damage
to the piston and the cylinder.
To examine if the carburetor is correctly
adjusted
• Make sure that the product has the correct
acceleration capacity.
• Make sure that the product 4-cycles a little at full
throttle.
• Make sure that the saw chain does not rotate at idle
speed.
• If the product is not easy to start or has less
acceleration capacity, adjust the low and high speed
needles.
CAUTION: Incorrect adjustments can
cause damage to the engine.
