MAINTENANCE
Adjustment of the oil pump
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.
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.
”Air Injection” centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburetor passes through the starter. Dirt and dust is
pushed out by the cooling fan.

Recommended settings:
Bar 13"-15": Position 1
Bar 15"-18": Position 2
Bar 18"-20": Position 3
WARNING! The engine must be stopped
when making adjustments.

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.
Cooling system
Winter use
Running problems can occur when using the machine in
the cold and snowy conditions caused by:
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
•
•
Too low engine temperature.
The cooling system consists of:
Icing of the air filter and carburetor.

Air intake on the starter.
Air guide plate.
Special measures are therefore often required:
•
Partly mask the air inlet on the starter to increase the
working temperature of the engine.
Fins on the flywheel.
•
Preheat the intake air to the carburetor by using the
heat from the cylinder.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).

Temperature 0°C (32°F) 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
carburetor space preventing icing of the air filter, etc.
