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 with the screw set to 
position 2. Turning the screw clockwise will reduce the oil flow 
and turning the screw anti-clockwise will increase the oil flow.

Recommended settings:

Bar 13"-15": Position 1

Bar 15"-18": Position 2

Bar 18"-20": Position 3

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.

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.

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.

(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.

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.
