Cooling system
To obtain the lowest possible running temperature the saw is
equipped with a cooling
system.The cooling system
consists of:
1. Air intake on the starter
unit.
2. Air guide plate.
3. Fan blades on the
flywheel.
4. Cooling fins on the
cylinder.
5. Cylinder cowling
(supplies 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 saw overheating which causes damage to
piston and cylinder.
Winter use
During winter time, powder snow and cold weather can cause
running problems, such as:
• Too low engine temperature.
• Icing on the air filter and carburettor.
Therefore some special measures are required:
• Partly reduce the air inlet of the starter and by doing that
increase the engine temperature.
• Preheat the intake air to the carburettor by removing the
special plug between the cylinder and the carburettor space.
Temperature -5°C or colder:
Twist the cover flap so that
preheated air from the
cylinder can enter the
carburettor chamber to
prevent icing of the filter. Fit
the rubber seal to the fuel pipe
by the main air intake.
IMPORTANT! Any maintenance other than that described in
this manual must be carried out by your servicing dealer.
