FUELHANDLING
Fuel mixture
CAUTION! The machine is equipped with
a two-stroke engine and must always be
run using a mixture of gasoline 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 sinai+ amounts of
fuel, even smelt inaccuracies can drasticaF
ty effect the ratio of the mixture
&WARNING: Always ensure
there is adequate ventilation when
handling fuel.
Gasoline
CAUTION! Always use high quality
unleaded gasoline
•This engine is certified to operate on
unleaded gasoline.
• The _owest recommended octane rating
is 87. If you run the engine on lower oc-
tane rating than 87, "knock{ng" can oc-
cur. This leads to an increased engine
temperature, which can resutt in a serb
ous engine breakdown.
• When working at continuous high rays a
higher octane rating is recommended.
Two-stroke oil
• For great resutts and performance use
HUSQVARNA two-stroke oil, which is
special+y formutated for our two-stroke
engines. Mixture 1:50 (2%).
• To maximize the life of your blower, you
may choose to use a high quality syn-
thetic oil formulated for two-stroke
engines. Mixture 1:50 (2%).
• Never use two-stroke oi+ intended for
water-cooled outboard engines,
sometimes referred to as outboard oil.
• Never use oit 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.
&WARNING: tmproper mainte-
nance could result in serious engine
damage or in serious injury.
Carburetor
Your Husqvama 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 witt
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.
Function
• The carburetor governs the engine's
speed vie the throttle control Air and fuel
are mixed in the carburetor.
• The T-screw (BB) 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
• The basic carburetor settings are ad-
justed during testing at the factory. Fine
adjustment should be carried out by a
skirled technician.
Recommended 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 T-screw if it is necessary to readjust.
The idlespeed is correctly adjusted when
the engine wilt run smoothly inevery posi-
tion.
BB
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.
The muffler is designed to dampen the
noise level and to direct the exhaust fumes
away from the use£ 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.
Some mufflers are equipped with a special
spark arresting screen (CC). If your ma-
chine is fitted with this type of screen, it
should be cieaned regulady. 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
cieaned 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 wiil cause the
engine to overheat resulting in damage to
the cyiinder and piston
CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.

MAINTENANCE
/CC
_1 WARNING: Mufflersfitted 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!
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!
_1_ 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 coefing
system for maintaining the right operating
temperature•
The cooling system consists of the follow-
ing components:
1. Air intake on the starter device (DD).
2. Fan blades on the flywheel (EE).
3. Cooling fins on the cylinder (FF).
4. Cylinder cowling (guides cooling a{r f_ow
aga{nst cylinder surfaces).
Ctean the coefing system by brushing once
a week, or more often, if necessary.
A dirty or b_ocked coefing system will
cause the b_ower to overheat and this will
damage the cytinder and piston
EE
Air filter
The air filter (GG) must be regulady cleaned
to remove dust and dirt in order to avoid:
•Carburetor mallunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts
• Excessivefuef consumption
• Elevated content of harmful exhaust
fumes•
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remove the air fiEter cover (HH) and take out
the filter. Wash it clean in warm, soapy water•
Rinse thoroughly. Ensure that the _ter 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.
545154658 Rev. 5 7/15/08 English-17
MAINTENANCE
Spark plug
The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or in-
correct type of oil).
• Poor quality gasoline and/or oil
• A dirty air fitter.
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
0.024" (0.6 mm) The spark plug should be
replaced after about a month in operation or
earlier if necessary.
0.024" (0.6 ram)
CAUTION! Always use the recommended
spark p_ug typet Use of the wrong spark
plug can damage the piston/cylinder.
