With the engine turned off, hold the chain saw over a stump 
or other firm object. Let go of the front handle so that the 
bar drops towards the stump as the chain saw rotates 
around the rear handle.

When the bar hits the stump the brake should be 
applied. (48)

Place the chain saw on firm ground and start it. Make sure 
the chain does not touch the ground or any other object. 
See the instructions under the heading Start and stop.

Grasp the chain saw firmly, wrapping your fingers and 
thumbs around the handles.

Apply full throttle and activate the chain brake by tilting your 
left wrist forward onto the front hand guard. Do not let go of 
the front handle. The chain should stop immediately.

• Make sure the throttle control is locked at the idle setting 

when the throttle lockout is released.

• Press the throttle lockout and make sure it returns to its 

original position when you release it.

• Check that the throttle control and throttle lockout move 

freely and that the return springs work properly.

• Start the chain saw and apply full throttle. Release the 

throttle control and check that the chain stops and 
remains stationary. If the chain rotates when the throttle 
control is in the idle position you should check the 
carburetor idle adjustment.

Check that the chain catcher is not damaged and is firmly 
attached to the body of the chain saw.

Check that the right hand guard is not damaged and that 
there are no visible defects, such as cracks.

Regularly check the vibration damping units for cracks or 
deformation.

Make sure the vibration damping units are securely 
attached to the engine unit and handle unit.

Start the engine and make sure the engine stops when you 
move the stop switch to the stop setting.

Never use a machine that has a faulty muffler. Regularly 
check that the muffler is securely attached to the machine.

Note: The spark arrestor screen (A) on this machine is 
serviceable. (49) The screen must be replaced if it is 
damaged. If the screen is blocked the machine will 
overheat and this will cause damage to the cylinder and 
piston. Never use a machine with a muffler that is in poor 
condition. Never use a muffler if the spark arrestor 
screen is missing or defective.

For normal homeowner use, the muffler and spark 
arresting screen will not require replacement. After 75 
hours of use, we recommend that your muffler be replaced 
by your authorized Husqvarna service dealer.

The air filter must be regularly cleaned to remove dust and 
dirt in order to avoid:

• Carburettor malfunctions

• Starting problems

• Loss of engine power

• Unnecessary wear to engine parts

• Excessive fuel consumption.

• Remove the air filter (3) after taking off the cylinder 

cover, screw (1) and filter cover (2). When refitting make 
sure that the air filter seals tightly against the filter 
holder. Clean the filter by brushing or shaking it. (50)

The filter can be cleaned more thoroughly by washing it in 
water and detergent.

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. A damaged air filter 
must always be replaced.

A HUSQVARNA chain saw can be equipped with different 
types of air filters according to working conditions, weather, 
season, etc. Contact your dealer for advice.

The spark plug condition is influenced by:

• Incorrect carburetor adjustment.

• An incorrect fuel mixture (too much or incorrect type of 

oil).

• A dirty air filter.

These factors cause deposits on the spark plug electrodes, 
which may result in operating 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 0.020 inch (0.5 
mm). The spark plug should be replaced after about a 
month in operation or earlier if necessary.

Note! Always use the recommended spark plug type! Use 
of the wrong spark plug can damage the piston/cylinder. 
Check that the spark plug is fitted with a suppressor.
