Adjustment of the oil pump
Heated handles (357XPG, 359G)
On the models 357XPG and
both the front handle and
359G
the rear handle are equipped
with electrical heating coils.
These are supplied with
electricity from a built-in genera-
tor in the electrical system.
The oil pump is adjustable.
Adjustments are made by turning
the screw using a screwdriver or
combination spanner. The saw 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.

WARNING! The engine must not be running
when making adjustments.
Recommended settings:

Bar 15"-18": Position 2
Bar 18"-20": Position 3
(357XPG,
359G)
This chain saw is, if it has model code XPG, equipped with
electrically heated carburetor. The electrically powered heating
prevents ice from forming in the carburetor. A thermostat
controls the heating so that the carburetor always has the right
working temperature.
Cooling system
Winter use
During winter time, powder snow and cold weather can cause
running problems, such as:
To obtain the lowest possible running temperature the saw is
equipped with a cooling system.

The cooling system

Too low engine temperature.
Icing on the air filter and carburetor.
consists of:

1.
Air intake on the starter
unit.
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 carburetor by removing the
special plug between the cylinder and the carburetor space.

Air guide plate.
•
Fan blades on the
flywheel.
The cylinder cover is made so it can be changed for running in
cold weather. There is a possibility to make a hole in which, during
the warmer part of the year, should be sealed using a plug.

Cooling fins on the
cylinder.

Cylinder cowling
(supplies cold air over
the cylinder).
Temperature 0 C (32 F) or colder

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.
NOTE! The cooling system of chain saws that are fitted with a
catalytic converter must be cleaned daily. This is particularly
important on saws with catalytic converters, because the
higher working temperature of the exhaust demands efficient
cooling of the engine and the catalytic converter unit.
Make a hole or remove the
plug so that the preheated
air from the cylinder can
pass into the carburetor area
preventing for instance icing
on the air filter.
Temperature -5°C (23 F) or colder:
o
Centrifugal cleaning ”Air Injection”
Centrifugal cleaning means
the following:
All air to the carburetor is
carried through the starter.
Dirt and dust is centrifuged
away by the cooling fan.
For running the saw in cold
weather or powder snow, a
special cover is available,
which is mounted on the
starter housing. This
reduces the air flow and
prevents large amounts of
snow from being sucked in.
IMPORTANT! In order to
keep the function of the
centrifugal cleaning, a
continous maintenance and
care must be made.
IMPORTANT! If a special winter kit is assembled or measures
are taken to increase the engine temperature, a readjustment to
normal setting has to be done when the saw is used under
normal conditions. Otherwise, there is a risk of overheating,
which can cause severe engine damage.
•
Clean the air intake to the
starter, the fan wings of the
flywheel, the space around
the flywheel, inlet pipe and
carburetor space.
IMPORTANT! Any maintenance other than that described in
this manual must be carried out by your servicing dealer.
