The owner is responsible for the perfor-
mance of all required maintenance as
defined in the operator's manual.
WARNING:
Improper mainte-
nance could result in serious engine
damage or in serious injury.
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.
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.
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.
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.
Rec. idle speed:

MAINTENANCE
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.
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 adjuster screw (A) clock-
wise until the cutting attachment starts to
rotate. Then turn adjuster screw (A)
clockwise an additional 1/2 turn.
4. If the start throttle speed is too high, turn
adjuster screw (A) counterclockwise
until the cutting attachment stops. Then
turn adjuster screw (A) clockwise an
additional 1/2 turn.
WARNING:
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.
