2. Blades
To ensure good cutting results
it is important that the contact
pressure between the blades is
correct.
The contact pressure between
the blades is adjusted by
tightening the screws on the
underside of the bar as far as
they will go, then backing
them off 1/4 turn. Lock the
screws using the locking nuts
on the top face of the bar. The
washers should still slide freely
under the screw heads after the
screws have been tightened.
When the blades are correctly
adjusted the play between the
blades should be 0.2–0.4 mm,
measured at the screws.
The edges of the blade are too
hard to be filed. Dull blades
should be sharpened using a
grinder.
Replace the blades if they are
bent or damaged.

MAINTENANCE
Carburettor
Your Husqvarna product has been designed and manufactured
to specifications that reduce harmful emissions.
After your unit has been run 8-10 tanks of fuel the engine has
broken in. To ensure that your unit is at peak performance and
producing the least amount of harmful emissions after break
in, have your authorized servicing dealer, who has a revolution
counter at his disposal, to adjust your carburettor for optimum
operating conditions.
WARNING!
!
Operation
• The carburettor governs
the engine’s speed via the
throttle. Air/fuel is mixed
in the carburettor. The
air/fuel mixture is
adjustable. To take
advantage of the engine’s
optimal output the
adjustment must be
correct.
• The setting of the
carburettor means that
the engine is adapted to
local conditions, for
example, the climate,
altitude, petrol and the
type of 2-stroke oil.
• The carburettor is equipped with three adjustment possibilities:
H = High speed needle
L = Low speed needle
T = Idle speed adjuster screw
• The fuel quantity in relation to the air flow permitted by
the throttle opening is adjusted using the L and H-needles.
Turning the needles clockwise gives a leaner fuel mixture
(less fuel) and turning them anti-clockwise gives a richer
fuel mixture (more fuel). A leaner mixture gives high revs
while a richer mixture give less revs.
• The T-screw regulates the position of the throttle while the
engine is idling. Turning the screw clockwise gives a higher
idling speed while turning it anti-clockwise gives a lower
idling speed.
The complete clutch cover and gear must
be fitted before the machine is started,
otherwise the clutch may come loose and
cause injury.
Basic setting
• The carburettor is set to its basic setting when test run at
the factory. The basic setting is richer than the optimal
setting and should be kept during the machine’s first
working hours. Thereafter the carburettor should be finely
adjusted. Fine adjustment should be carried out by a skilled
technician.
NOTE! If the cutting attachment rotates/moves while the
engine is idling the T-screw should be turned anti-clockwise
until the cutting attachment stops.
Recommended idling speed is 2 700 rpm.
Recommended max. speed: See “technical data”.
WARNING!
If the idling speed cannot be adjusted so
!
that the cutting attachment stops, contact
your service workshop. Do not use the
machine until it has been correctly
adjusted or repaired.
Fine adjustment
• When the machine has been ”run-in” the carburettor should
be finely adjusted. The fine adjustment should be carried
out by qualified person. First adjust the L-jet, then the
idling screw T and then the H-jet.
Conditions
• Before any adjustments are made the airfilter should be clean
and the airfilter cover fitted. Adjusting the carburettor while
a dirty airfilter is in use will result in a leaner mixture when
the filter is finally cleaned. This can give rise to serious
engine damage.
• Carefully turn the L and H needle to the mid point between
fully turned in and fully turned out.
• Do not attempt to adjust the needles beyond the stops as
damage can occur.
• Now start the machine according to the starting instructions
and run it warm for 10 minutes.
NOTE! If the cutting attachment rotates/moves the T screw
should be turned anti-clockwise until the cutting attachment
stops.
Low speed needle L
Try to find the highest idling
speed, turning the low speed
needle L clockwise respectively
counter-clockwise.
When the highest speed has
been found, turn the low
speed needle L 1/4 turn
counter-clockwise.
NOTE! If the blades move
when the engine is idling,
turn the idling speed screw
T counter-clockwise until
the blades stop.

MAINTENANCE
Adjusting the idle 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
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.
+ 1/4
L
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.
Gearbox
There are three grease
nipples (A) on the gearbox.
Use a grease gun to top up
with grease. This should be
carried out after approximately every 20 working
hours. Use Husqvarna special
grease, No. 503 98 96-01.
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
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.
H
Note that the gearbox must
not be filled completely
with grease. The grease
expands as the machine
heats up during operation.
If the gearbox was completely filled with grease it
could damage the seals and
lead to leakage.
The lubricant in the gearbox
does not normally need to be
replaced other than with
repair.
Cleaning and
lubrication
After you have used the
machine clean any resin and
plant residue from the blades
using cleaning agent 531 00
60-75 (UL22).
Always lubricate the blade
runners with special grease
531 00 60-74 (UL 21)
before use.
NOTE! For optimum setting of the carburettor, contact a
qualified servicing dealer who has a revolution counter at his
disposal.
