FUEL HANDLING
Fuel mixture
NOTE!
The machine is fitted with a two-stroke engine and
must always be run on a mixture of gasoline and
two-stroke oil. It is important to measure the quantity
of oil accurately, to ensure the correct mixture ratio.
Small discrepancies in the amount of oil have a
great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.
WARNING!
!
Allow adequate ventilation while
handling fuel.
Gasoline
NOTE!
Always use an oil-mixed quality gasoline (at least 87
octane). If your machine is equipped with a catalytic
converter,
mixed quality gasoline should always be used. A
leaded gasoline will destroy the catalytic converter.
(see “technical data”)
an unleaded, oil
• This engine is certified to operate on
unleaded gasoline.
• The lowest recommended octane rating is 87. If
you run the engine on lower octane rating than
87 so-called “knocking“ can occur. This leads to
an increased engine temperature, which can
result in a serious engine breakdown.
• When working at continuous high revs a higher
octane rating is recommended.
Two-stroke oil
• For the best performance, use HUSQVARNA
two-stroke oil, which has been specially
developed for Husqvarna two-stroke engines.
Mixing ratio: 1:50 (2%).
• If HUSQVARNA two-stroke oil is not available,
you may use another two-stroke oil of good
quality that is intended for air-cooled engines.
Contact your dealer when selecting an oil.
• Never use two-stroke oil intended for watercooled marine outboard motors, so-called
outboard oil.
• Never use oil intended for four-stroke engines.
12 – English
Page 13
O
FUEL HANDLING
Mixture
• Always mix gasoline and oil in a clean container
intended for fuel.
• Always start by filling half the quantity of gasoline
required. Then add the entire oil quantity. Mix
(shake) the fuel mixture. Fill the remaining quantity
of gasoline.
• Mix (shake) the fuel mixture carefully before filling
in the machine‘s fuel tank.
• Do not mix more than max. one month’s supply of
fuel.
• If the machine is not used for a long period of
time, the fuel tank should be emptied and cleaned.
• This engine is certified to operate on unleaded
gasoline.

MAINTENANCE
Carburetor
The carburetor has been carefully preset at the factory . However, additional adjustment may be required
due to climate, altitude, gasoline and type of twostroke engine oil used. The instructions below
describe how carburetor adjustment should be
carried out.
The carburetor governs the engine speed via the
throttle. Air and fuel are mixed in the carburetor. The
air/fuel mixture is adjustable. To utilize the blower’s
maximum output, the settings must be correct.
The carburetor has three means of adjustment:
H = High speed jet
L = Low speed jet
T = Adjustment screw for idling
H L T
Basic (factory) settings
The carburetor is preset to the basic settings when
the blower is tested at the factory. These basic
settings are the following:
The H screw has been turned counterclockwise
to its end position against the stop.
The L screw has been turned counterclockwise
to its end position against the stop.
The recommended idling speed is 3000 rpm.
Adjustment
NOTE!
Do not remove the stops in the H and L
jets. If these stops are removed, the
blower will no longer satisfy the
environmental requirements established
by the California Air Resources Board.
Low speed jet, L
1. Check that the blower tube (15) and the nozzle
(14) are mounted on the blower.
Function
The fuel quantity required in relation to the air flow,
provided by the opening in the throttle, is adjusted
by the L and H jets. If they are screwed clockwise,
the air/fuel mixture becomes leaner (less fuel) and if
they are screwed counterclockwise, the mixture
becomes richer (more fuel). A leaner mixture gives
rise to a higher engine speed and a richer mixture
gives rise to a lower engine speed.
The T screw regulates the idling speed. Turning the
T screw clockwise will increase the idling speed;
turning it counterclockwise will lower the idling
speed.
2. Turn the H and L adjustment screws fully counterclockwise so that they rest against the stop.
3. Start the blower engine, see page 13, and
alternate letting it run at idling speed and at half
throttle for 1-2 minutes to warm up. If the engine
will not run at idling speed, turn the T screw
clockwise until it does.
4. Set the T screw to the setting, at which the engine
runs precisely at idling speed, but not faster.
5. Make a fine adjustment, turning the L screw so
that the engine will run at max. idling speed. Then
turn the L screw max 1/4 of a turn
counterclockwise.
6. Then turn the T screw to increase the engine
speed, if necessary.
NOTE!
When setting the H jet, the max.
permissible full-throttle interval is 10
seconds, after which the engine must run
at idling speed for at least 10 seconds.
High speed jet, H
1. Start the blower as described on page 13 and
alternate letting it run at idling speed and at half
throttle for 1-2 minutes to warm up.
2. Give the engine full throttle and adjust the H
screw until the engine runs at maximum speed.
3. Turn the H screw 1/8 of a turn counterclockwise
(less than 1/8 of a turn if the stop restricts this
adjustment).

“Technical data”
saw is fitted with a catalytic converter.
The muffler is designed to dampen the noise level
and to direct the exhaust fumes away from the user.
The exhaust fumes are hot and can contain sparks,
which can result in fire if the exhaust fumes are
directed towards a dry and inflammable material.
Some mufflers are equipped with a special spark
arrest screen. If your machine is fitted with this type
of screen it should be cleaned regularly. This is done
using a wire brush. On mufflers without a catalytic
converter the screen should be cleaned weekly, or
replaced if necessary. On mufflers fitted with a
catalytic converter the screen should be checked
and cleaned monthly. If the screen is damaged it
should be replaced. If the screen is frequently
blocked, this can be a sign that the function of the
catalytic converter is impaired. Contact your dealer
to inspect the muffler. A blocked screen will cause
the engine to overheat resulting in damage to the
cylinder and piston. Also see under
to see whether you clearing
“Maintenance”
.
NOTE!
Never use a machine with a defective muffler.
Cooling system
The engine is equipped with a cooling system for
maintaining the right operating temperature.
The cooling system consists of the following
components:
1. Air intake on the starter device.
2. Fan blades on the flywheel.
3. Cooling fins on the cylinder.
4. Cylinder cowling (guides cooling air flow against
cylinder surfaces).
Clean the cooling system by brushing once a week,
or more often, if necessary.
A dirty or blocked cooling system will cause the
blower to overheat and this will damage the cylinder
and piston.

The air filter (A) must be cleaned regularly to
remove dust and dirt. This will prevent:
• Carburetor malfunctions
• Starting problems
• Reduced performance
• Unnecessary wear on engine parts
• Abnormal fuel consumption
• Elevated content of harmful exhaust fumes
Clean the filter after 25 hours of operation or more
often if the air is exceptionally dusty in the work
area.
To clean the air filter
Dismantle the air filter cover (B) and remove the
filter medium. Wash it clean in a solution of soap
and warm water. Make sure that the filter is dry
before reassembling.
An air filter, which has been used for some time, cannot be cleaned completely. Therefore,the filter must
be replaced by a new one at regular intervals. A
faulty filter must always be replaced.
B A
Spark plug
The condition of the spark plug is influenced by:
• An incorrectly adjusted carburetor.
• Wrong fuel mixture (too much oil in the
gasoline).
• Poor quality gasoline and/or oil.
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
difficulty starting the blower.
If the engine is low on power, difficult to start or
runs poorly at idling speed, always check the
spark plug first.
The spark plug is accessible under the cylinder
shrouding, which can be removed by unscrewing
four screws.
If the spark plug is clogged, clean it and check the
electrode gap. Re-adjust if necessary. The correct
gap is 0.5 mm (0.020”). The spark plug should be
replaced after about one month of operation or
earlier if the electrodes are badly eroded.
0,5 mm
NOTE! Always use the recommended type of spark
plug! See under ”Technical data”. An incorrect spark
plug can severely damage the piston/cylinder.
