MAINTENANCE
Tensioning the recoil spring
• Hook the starter cord in the notch in the pulley and turn the
starter pulley about 2 turns clockwise.
Note! Check that the pulley can be turned at least a further
1/2 turn when the starter cord is pulled all the way out.
Changing a broken recoil spring
• Lift up the starter pulley. See instructions under the
heading Changing a broken or worn starter cord.
Remember that the recoil spring is coiled under tension in
the starter housing.
•
Remove the recoil spring from inside the pulley by tapping
the pulley lightly with its inside face downwards against a
work bench or the like. If the spring pops out during fitting,
wind it up again, working from the outside in towards centre.
• Lubricate the recoil spring with light oil. Fit the cassette
with recoil spring in the starter. Fit the starter pulley and
tension the recoil spring.
Fitting the starter
• To fit the starter, first pull out the starter cord and place the
starter in position against the crankcase. Then slowly
release the starter cord so that the pulley engages with
the pawls.
• Fit and tighten the screws that hold the starter.
Air filter
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 after taking off the air filter cover. When
refitting make sure that the air filter seals tightly against the
filter holder. Clean the filter by brushing or shaking it.
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 filter according to working conditions, weather,
season, etc. Contact your dealer for advice.
Spark plug
The spark plug condition is influenced by:
• Incorrect carburettor 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 0.5 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.
