MAINTENANCE
Needle bearing maintenance
The clutch drum is equipped
with one of the following chain
sprockets:
• Spur sprocket (A) (the chain
sprocket is welded on the
drum)
• Rim sprocket (B)
(exchangeable)
Both versions have built-in
needle bearing at the drive
shaft, whitch has to be
greased regularly (once a
week).
NOTE! Use only high quality bearing grease.

Adjustment of the oil pump
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 set to 1 turn
open. 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 11"-15": 0-2 turns from the closed position.
Bar 15"-18": 2-3 turns from the closed position.
Cooling system
To obtain the lowest possible running temperature the saw is
equipped with a cooling system.The cooling system
consists of:
1. Air intake on the starter unit.
2. Air guide plate.
3. Fan blades on the flywheel.
4. Cooling fins on the cylinder.
5. Cylinder cowling (supplies
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 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.

Heated handles
On the model XPG both the
front handle and the rear
handle are equipped with
electrical heating coils. These
are supplied with electricity
from a built-in generator in the
electrical system. The switch
for the heating coils is placed
to the right of the rear handle.
When the switch is pushed to
the right, the heat is switched
on. When it is pushed to the
left, the heat is switched off.
Winter use
During winter time, powder snow and cold weather can cause
running problems, such as:
• Too low engine temperature.
• Icing on the air filter and carburettor.
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 carburettor by removing the
special plug between the cylinder and the carburettor space.
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.
Temperature 0
o
C (32
o
F) or colder
Make a hole or remove the
plug so that the preheated
air from the cylinder can
pass into the carburettor
area preventing for instance
icing on the air filter.
Temperature -5
o
C (23
o
F) or colder
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! 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.
IMPORTANT! Any maintenance other than that described in
this manual must be carried out by your servicing dealer.
