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.

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.

MAINTENANCE

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 speed

needle. Therefore dismantle

the cutting equipment, nut,

support flange and disc drive

H

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.

Adjusting the start throttle speed

The correct start throttle

speed is set by means of an

adjuster on the rear of the

handle next to the cable. Use

this screw (4 mm Allen

screw) to increase or

decrease the start throttle

speed.

Proceed as follows:

1. Run the machine at

idle.

2. Press the start throttle

lock as described under

the heading ”Starting

and stopping”.

3. If the start throttle speed is too low (below 4000 rpm),

turn the adjuster screw A clockwise until the cutting

attachment starts to rotate. Then turn A clockwise a

further 1/2 turn.

4. If the start throttle speed is too high, turn the adjuster

screw A anticlockwise until the cutting attachment stops.

Then turn adjuster screw A clockwise a further 1/2 turn.
