MAINTENANCE

Final setting of the idling speed T

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 cutting attachment starts to rotate/ move.

Then turn, counter- clockwise until the cutting attachment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the cutting attachment starts to rotate/move.

CAUTION! Contact your servicing dealer, if the idle speed

Correctly adjusted carburetor

A correctly adjusted carburetor means that the machine accelerates without hesitation and the machine 4-cycles a little at max speed. Furthermore, the cutting attachment must not rotate/move 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 power = less capacity, bad acceleration and/or damage to the engine. A too rich adjustment of the two speed needles L and H gives acceleration problems or too low working speed.

Adjusting the throttle wire

setting cannot be adjusted so that the cutting attachment stops. Do not use the machine until it has been properly adjusted or repaired.

High speed needle

H

The high speed needle affects

the machine’s power, speed,

temperature and fuel

consumption. A too lean

adjustment on the high

speed needle H (the high

speed needle H is screwed in

too much) gives a too high

speed resulting in engine

damage. Do not allow the

engine to run at full speed

for more than 10 seconds.

If you cannot obtain full throttle you can adjust the throttle wire. Turning the screw (A) clockwise pushes out the throttle wire casing so that full throttle can be obtained. If the engine runs too fast at idle the throttle wire casing can be shortened by turning screw (A) anticlockwise. CAUTION! Check that the idle screw T is correctly adjusted first (see instructions under the heading Fine adjustment of the idle speed T).

before adjusting the high speed needle. The high speed needle is adjusted correctly when the machine ‘splatters’ a little . If the machine smokes heavily at the same time as it ‘splatters’ heavily the adjustment is too rich.

NOTE! For optimum setting of the carburetor, contact a qualified servicing dealer who has a revolution counter at his disposal.

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