MAINTENANCE

Carburetor

Your Husqvarna 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

S

The carburetor governs the engine’s

speed via the throttle control. Air and fuel

are mixed in the carburetor.

S

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

S

The basic carburetor settings are ad-

justed during testing at the factory. Fine

adjustment should be carried out by a

skilled technician.

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.

WARNING:

The cutting attach-

ment may be spinning during carbu-

retor adjustments. Wear your protec-

tive equipment and observe all safe-

ty instructions. Be sure the cutting

attachment stops turning when the

engine idles. When the unit is turned

off, make sure the cutting attach-

ments has stopped before the unit is

set down.

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 counterc-

lockwise 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 at-

tachment starts to rotate.
