MAINTENANCE
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.
”Air Injection” centrifugal cleaning
Centrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged 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 carburettor
compartment.
Heated handles
(357 XPG, 359 G)
On models with the model code XPG/G both the front handle
bar and the rear handle are equipped with electrical heating
coils. These are supplied with electricity from a generator built
into the chain saw.
When the switch is pushed upwards, the heat is switched on.
When the switch is pushed downwards, the heat is switched
off.
Electrical carburettor heating
(357 XPG, 359 G)
If this chain saw has the model code XPG/G then it is
equipped with an electrically heated carburettor. The
electrical heating prevents icing in the carburettor. A
thermostat regulates heating so that the carburettor always
has the correct working temperature.
Winter use
During cold weather and under powder snow conditions,
operating problems can arise due to:
• Too low engine temperature.
• Icing of the air filter and carburettor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
Temperature 0°°

C 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 carburettor
space preventing icing of the air filter, etc.
