Cooling system
Heated handles
(346XPG,
353G)
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.
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:

Air intake on the starter.
Air guide plate.
Fins on the flywheel.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).

When the switch is pushed upwards, the heat is switched on.
When the switch is pushed downwards, the heat is switched
off.

Electrical carburetor heating

(346XPG, 353G)
If this chain saw is marked with Carburetor Heating 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.
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.
Winter use
Running problems can occur when using the machine in the
cold and snowy conditions caused by:
•
•
Too low engine temperature.
”Air Injection” centrifugal cleaning
Icing of the air filter and carburetor.
Centrifugal cleaning means the following: All air to the
carburetor passes through the starter.Dirt and dust is pushed
out by the cooling fan.
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.
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.
