MAINTENANCE

Carburetor

Your Jonsered product has been designed

and manufactured to specifications that re-

duce harmful emissions. After the engine

has used 8--10 tanks of fuel, the engine will

be run--in. To ensure that it continues to run

at peak performance and to minimize harm-

ful exhaust emissions after the run--in peri-

od, ask your servicing dealer to adjust your

carburetor.

The owner is responsible for the perfor-

mance of all required maintenance as

defined in the operator’s manual.

WARNING:

The complete clutch,

clutch cover, and shaft must be

fitted before the machine is started,

otherwise parts could come loose

and cause personal injury.

Function

The carburetor governs the engine’s

speed via the throttle control. Air and fuel

are mixed in the carburetor.

The T--screw regulates the throttle setting

at idle speed. If the T--screw is turned

clockwise this gives a higher idle speed;

turning it counterclockwise gives a lower

idle speed.

Basic setting

The basic carburetor settings are ad-

justed during testing at the factory. Fine

adjustment should be carried out by a

skilled technician.

Rec. idle speed:

See “Technical data” section.

Recommended max. speed:

See “Technical data” section.

Fine adjustment of the idle speed--T

Adjust the idle speed using the idle adjust-

ment screw--T if it is necessary to readjust.

First, turn the idle adjustment screw--T

clockwise until the cutting attachment starts

to rotate. Then, turn the screw counter-

clockwise until the cutting attachment stops.

The idle speed is correctly adjusted when

the engine will run smoothly in every posi-

tion. The idle speed should also be well

below the speed at which the cutting attach-

ment starts to rotate.

CAUTION!

If the cutting attachment rotates

when the engine is idling the idle adjustment

screw T should be turned counterclockwise

until the cutting attachment stops.

Idle Speed

Screw--T

WARNING:

If the idle speed can-

not be adjusted so that the cutting

attachment stops, contact your ser-

vicing dealer. Do not use the ma-

chine until it has been correctly ad-

justed or repaired.

Unit/Maintenance Safety

Disconnect the spark plug before perform-

ing maintenance, except carburetor adjust-

ments.

Muffler

The muffler is designed to reduce the noise

level and to direct the exhaust gases away

from the operator. The exhaust gases are

hot and can contain sparks, which may

cause fire if directed against dry and com-

bustible material.

Mufflers are equipped with a special spark

arrestor mesh. You should clean the mesh

at least once a month. This is best done

with a wire brush.

If the mesh is damaged

it should be replaced.

A blocked mesh

will cause the machine to overheat and re-

sult in damage to the cylinder and piston.

Muffler bolts

CAUTION!

Never use a machine that has

a faulty or loose muffler. Ensure the muffler

bolts are tight.
