MAINTENANCE
• Undo the bolt in the centre of the pulley and remove the
drive disc, drive disc spring and the pulley. Insert and
secure a new starter cord in the starter pulley. Wind
approx. 3 turns of the starter cord on the starter pulley. Fit
the starter pulley so that the end of the recoil spring hooks
into the starter pulley. Now assemble the drive disc spring,
drive disc and the bolt in the centre of the pulley. Carry the
starter cord through the hole in the starter housing and the
starter handle. Tie a good knot on the starter cord.
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 an additional 1/
2 turn when the starter cord is pulled all the way out.
Replacement of broken recoil and drive
disc springs
Recoil spring (A)
• 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 cassette with the recoil spring from the
starter.
• 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.
Drive disc spring (B)
• Undo the bolt in the centre of the pulley and remove the
drive disc and the drive disc spring.
• Replace the drive disc spring and fit the drive disc above
the 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 JONSERED chain saw can be equipped with different types
of air filter according to working conditions, weather, season,
etc. Contact your dealer for advice.
