MAINTENANCE
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine
accelerates without hesitation and the machine 4-cycles a
little at max speed. It is also important that the chain does not
rotate at idle. If the L-jet is set too lean it may cause starting
difficulties and poor acceleration. If the H-jet is set too lean
the machine will have less power, poor acceleration and could
suffer damage to the engine. If the L and H-jets are set too
rich it will lead to acceleration problems or too low a working
speed.
Starter
Changing a broken or worn starter cord
• Loosen the screws that hold the starter against the
crankcase and remove the starter.
• Pull out the cord approx. 30 cm and hook it into the notch
in the rim of the pulley. Release the recoil spring by letting
the pulley rotate slowly backwards.
• Undo the screw in the centre of the pulley and remove the
pulley. Insert and fasten a new starter cord to the pulley.
Wind approx. 3 turns of the starter cord onto the pulley.
Connect the pulley to the recoil spring so that the end of
the spring engages in the pulley. Fit the screw in the
centre of the pulley. Insert the starter cord through the
hole in the starter housing and the starter handle. Make a
secure knot in the end of 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.
CAUTION! 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 by tapping the starter, with the
inside facing downwards, gently on a work bench. If the
spring pops out during assembly, coil it up from the
outside, working inwards.
!
WARNING! When the recoil spring is wound
up in the starter housing it is under tension
and can, if handled carelessly, pop out and
cause personal injury. Always be careful
when changing the recoil spring or the
starter cord. Always wear protective
goggles.
