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.
Note! The cooling system on a chain saw with catalytic 
converter must be cleaned daily. This is particularly 
important on chain saws with catalytic converters, 
because the higher exhaust temperature requires 
efficient cooling of the engine and the catalytic converter 
unit.
”Air Injection” centrifugal 
cleaning
Centrifugal cleaning means the following: All air to the 
carburetor passes through the starter. Dirt and dust is 
pushed out by the cooling fan.
IMPORTANT! In order to maintain operation of the 
centrifugal cleaning system it must be regularly 
maintained. Clean the air intake to the starter, the fins on 
the flywheel, the space around the flywheel, inlet pipe and 
carburetor compartment.
Winter use
Running problems can occur when using the machine in 
the cold and snowy conditions caused by:
Too low engine temperature.
Icing of the air filter and carburetor.
Special measures are therefore often required:
Partly mask the air inlet on the starter to increase the 
working temperature of the engine.
Preheat the intake air to the carburetor by using the 
heat from the cylinder.
Temperature 0
°°°°C (32°°°°F) or colder:
The cylinder cover is designed so it can be adjusted for 
running in cold weather. Twist the winter flap so that 
preheated air from the cylinder can pass into the 
carburetor space preventing icing of the air filter, etc.
For temperatures below -5
°C (23°F) and/or in snow 
conditions there is also:
a special cover (A) for the starter housing
a winter plug (B) for the air nozzle that is fitted as 
shown.
These reduce the flow of cooling air and prevent large 
amounts of snow from being sucked into the carburetor 
space.
CAUTION! When the winter plug is fitted the winter flap 
must be open!

IMPORTANT! If the temperature rises above -5
°C 
(23
°F) or 0°C (32°F) respectively the machine MUST be 
restored to its normal set-up. Otherwise there is a risk of 
overheating, which can cause severe engine damage.
