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 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.

 

Apply full throttle and turn

 

the high speed needle H

 

slowly anticlockwise until

 

the engine runs unevenly.

 

The high speed needle H is

 

then turned slowly clockwise

 

a little until the engine runs

 

smoothly. Note the engine

 

should be run unloaded

 

when adjusting the high

H

speed needle. Therefore

 

dismantle the cutting

 

equipment, nut, support

 

flange and disc drive 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 carburettor, contact a qualified servicing dealer who has a revolution counter at his disposal.

Correctly adjusted carburettor

A correctly adjusted carburettor 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.
