MAINTENANCE
Muffler
The muffler is designed to reduce the noise level and to direct
the exhaust gases away from the operator. The exhaust
gases are hot and can contain sparks, which may cause fire
if directed against dry and combustible material.
Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done with a
wire brush.
CAUTION! The mesh must be replaced if it is damaged. If the
mesh 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.
Needle bearing lubrication
The clutch drum is fitted with one of the following drive
sprockets:
A Spur sprocket (the chain sprocket is welded on the
drum)
B Rim sprocket (replaceable)
Both versions have a needle bearing on the drive shaft, which
has to be greased regularly (once a week).
CAUTION! Use a high-quality bearing grease or engine oil.
Adjustment of the oil pump
The oil pump is adjustable. Adjustments are made by turning
the screw using a screwdriver or combination spanner. The
machine is supplied from the factory set to 1 turn open.
Turning the screw clockwise will reduce the oil flow and
turning the screw anti-clockwise will increase the oil flow.
Recommended settings:
These recommendations apply to Husqvarna’s chain oil, for
other chain oils increase the oil flow by one step.
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 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover (directs cold air over the cylinder).
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.
!
