FUEL HANDLING
S Always start by filling half the amount of
Fuel mixture
the gasoline to be used. Then add the
entire amount of oil. Mix (shake) the fuel
mixture. Add the remaining amount of
gasoline.
CAUTION! The machine is equipped with
a two--stroke engine and must always be
run using a mixture of petrol and two--
stroke engine oil. It is important to accu-
rately measure the amount of oil to be
mixed to ensure that the correct mixture is
obtained. When mixing small amounts of
fuel, even small inaccuracies can drastical-
ly affect the ratio of the mixture.
S Mix (shake) the fuel mixture thoroughly
before filling the machine’s fuel tank.
WARNING: Always ensure
there is adequate ventilation when
handling fuel.
Petrol
S Do not mix more than one month’s sup-
ply of fuel at a time.
S If the machine is not used for some time,
the fuel tank should be emptied and
cleaned.
CAUTION! Always use a good quality
petrol/oil mixture (at least 90 octane).
Use low--emission petrol, also known as
alkylate petrol, if it is available.
WARNING: The catalytic con-
verter muffler gets very hot during
and after use. This also applies
during idling. Be aware of the fire
hazard, especially when working
near flammable substances and/or
vapors.
S The lowest octane recommended is 90.
If you run the engine on a lower octane
than 90, it can result in knocking. This
gives rise to a high engine temperature,
which can result in serious engine damage.
S When working at continuous high revs, a
higher octane rating is recommended.
Fueling
WARNING: Taking the following
precautions, will lessen the risk of
fire:
Do not smoke or place hot objects
near fuel.
Always shut off the engine before
refueling.
Always stop the engine and let it
cool for a few minutes before
refueling.
When refueling, open the fuel cap
slowly so that any excess pressure
is released gently.
Tighten the fuel cap carefully after
refueling.
Always move the machine away
from the refueling area before
starting.
Two--stroke oil
S For best results and performance, use
HUSQVARNA two--stroke oil, which is
specially formulated for our two--stroke
engines. Mixture 1:50 (2%).
S If HUSQVARNA two--stroke oil is not avail-
able, you may use another two-stroke oil of
good quality that is intended for air cooled
engines. Contact your dealer when select-
ing an oil. Mixing ratio 1:33 (3%).
S Never use two--stroke oil intended for
water--cooled outboard engines,
sometimes referred to as outboard oil.
S Never use oil intended for four--stroke
engines.

MAINTENANCE
Maintenance Safety
The owner is responsible for the perfor-
mance of all required maintenance as
defined in the operator’s manual.
Disconnect the spark plug before perform-
ing maintenance, except carburetor adjust-
ments.
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.
Muffler
Some mufflers are fitted with catalytic con-
verters. See the Technical data section to
find out if your machine is equipped with a
catalytic converter.
Function
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 flammable
material.
S The carburetor governs the engine’s
speed via the throttle control. Air and fuel
are mixed in the carburetor.
S The T--screw (X) 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.
Some mufflers are equipped with a special
spark arresting screen (Y). If your machine
is fitted with this type of screen, it should
be cleaned regularly. To access the
screen, remove the outlet cover on the
front of the muffler. Use a wire brush to
clean the screen. 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 fre-
quently blocked, this can be a sign that the
function of the catalytic converter is im-
paired. Contact your dealer to inspect the
muffler. A blocked screen will cause the
engine to overheat resulting in damage to
the cylinder and piston.
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.

Fine adjustment of the idle speed--T
Adjust the idle speed using the idle adjust-
ment T--screw if it is necessary to readjust.
The idle speed is correctly adjusted when
the engine will run smoothly in every posi-
tion.
CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.

MAINTENANCE
Y
Z
BB
AA
WARNING: Mufflers fitted with
catalytic converters get very hot
during use and remain so for some
time after stopping. This also ap-
plies at idle speed. Contact can re-
sult in burns to the skin. Remember
the risk of fire!
Air filter
WARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near flam-
mable material!
The air filter (CC) must be regularly cleaned
to remove dust and dirt in order to avoid:
S Carburetor malfunctions
S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts
S Excessive fuel consumption
S Elevated content of harmful exhaust
fumes.
WARNING: The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.

Cooling system
The engine is equipped with a cooling
system for maintaining the right operating
temperature.
The cooling system consists of the follow-
ing components:
1. Air intake on the starter device (Z).
2. Fan blades on the flywheel (AA).
3. Cooling fins on the cylinder (BB).
4. Cylinder cowling (guides cooling air flow
against cylinder surfaces).
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remove the air filter cover (DD) and take out
the filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before reinstalling it.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals.
CAUTION! A damaged air filter must
always be replaced.
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.

MAINTENANCE
Weekly maintenance
Spark plug
S Check the condition of the starter device,
the starter cord and the tensioning spring.
Replace damaged parts.
S Check the condition of the air intake at
the starter device. Remove debris if it is
clogged.
The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too much or in-
correct type of oil).
S Poor quality gasoline and/or oil
S A dirty air filter.
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing problems and starting difficulties.
If the machine is low on power, difficult to
start or runs poorly at idle speed: always
check the spark plug first before taking
any further action. If the spark plug is dirty,
clean it and check that the electrode gap is
0,6 mm. The spark plug should be replaced
after about a month in operation or earlier if
necessary.
S Clean the outside of the spark plug. Re-
move it and check the electrode gap. Ad-
just the gap to 0,6 mm, or replace the
spark plug. Use resistor spark plug
Champion RCJ--8Y or equivalent.
S Clean the fan blades on the flywheel.
S Clean or replace the spark arresting
screen (not on mufflers with a catalytic
converter).
S Clean the carburetor area.
S Clean the air filter.
Monthly maintenance
S Clean the fuel tank.
S Clean the outside of the carburetor and
the area around it.
0,6 mm
S Clean the fan blades on the flywheel and
the area around it.
S Check fuel lines for cracks or other dam-
age. Change if necessary.
S Change the fuel filter in fuel tank.
S Check all cables and connections. Re-
place damaged parts.
S Replace the spark plug. Use spark plug
Champion RCJ--8Y or equivalent.
S Change the air filter.
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.
Maintenance schedule
Below you will find some general mainte-
nance instructions.
Daily maintenance
S Clean the exterior surfaces of the blower.
S Check that the variable speed control and
the throttle trigger function in a safe man-
ner. Replace damaged parts.
