Adjusting the idle speed (T)
Check that the air filter is clean. When the idle speed is
correct, the cutting attachment should not rotate. If
adjustment is required, close (turn clockwise) the idle
adjustment screw T, with the engine running, until the
cutting attachment starts to rotate. Open (turn
anticlockwise) the screw until the cutting attachment
stops. The idle speed is correctly set when the engine
runs smoothly in all positions, and there is a clear margin
to the speed at which the cutting attachment starts to
rotate.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Fins on the flywheel.
2 Cooling fins on the cylinder.
3 Cylinder cover (directs cold air over the cylinder).
4 Muffler cover.
5 Muffler plate.
Clean the cooling system with a brush once a week, more
often in demanding conditions
. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Air filter
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Set the choke control in the choke position.
Cleaning the air filter
Remove the air filter cover. Remove the dust around the
filters.
Take out the filters.
Clean the foam plastic filter. (1)
Wash the filter in clean, warm soapy water.
Make sure that the filter is dry befor oiling it. Moisten the
foam plastic filter with Husqv
arna two-stroke engine oil.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distrib
ute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine.
Note:
!
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
