NOTE! Do not attempt to adjust the needlesbeyondthe stops as damagecan occur.

Low speed needle L

Try to find the highest idling speed by turning the low speed needle L within the limits of the limiter cap. When the highest speed has been found, turn the low speed needle L 1/16 turn counter-clockwise or to the limiter cap stop.

NOTE! If the chain rotates in the idling position, turn the idling speed screw counter-clockwise until the chain stops.

High speed needle H

Th= high speed needle H influences the power of the saw. A too lean adjusted high speed needle H (high speed needle H closed too much) gives overrevs and damages the engine. let the saw run at full speed for about 10 seconds. Thereafter, turn the high speed needle H 1/16 turn counter-clockwise. Let the saw run again at full speed for about 10 seconds and note the difference in the engines sound. The high speed needle H is correctly set when the saw “4-cycles”a little. If the saw “whistles”the setting is too lean. If there is too much exhaust gas at the same time as the saw “4cycles” much, the setting is too rich, Turn the high speed needle H until the setting sounds correct.

If the engine does not operate properly within the limiter cap range, do not use the unit. Take it to your Authorized Service Dealer

MOTE!For optimum setting of the carburetor, contact a qualified servicing dealer who has a revolution counter at his ~isposal. The maximum speed recommended, 13000 rpm, nust not be exceeded.

Adjust the idling speed with the screw T, If it is necessary to readjust, first turn the idle speed adjusting screw T clockwise, until the chain starts to rotate.

Then turn, counter-clockwise until the chain stops. A correctly adjusted idle speed setting (approx. 3000 rpm) occurs when the engine runs smoothly in every position.

It should also be good margin to the rpm when the chain starts to rotate.

CAUTION! contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops. Do not use the saw until it has been properly adjusted or repaired.

CARBURETORMIXTURE

NEEDLESWITHLIMITERCAPS

Correctly adjusted carburetor

Acorrectly adjusted carburetor means that the saw accelerate without hesitation and the saw 4-cycles a little at max speed. Furthermore, the chain must not rotate at idling. A too lean adjusted low speed needle L may cause starting difficulties and bad acceleration.

A too lean adjusted high speed needle H gives lower powerless capacity, bad acceleration and/or damage to the engine.

A too rich adjustment of the two speed needlea L and H gives acceleration problems or too low working speed.
