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 with the

 

2

1

 

screw set to position 2. Turning

 

 

 

 

the screw clockwise will reduce

3

 

 

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 13"-15": Position 1

Bar 15"-18": Position 2

Bar 18"-20": Position 3

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

4

 

 

unit.

3

2.

Air guide plate.

 

3. Fan blades on the flywheel.

4. Cooling fins on the cylinder.

5. Cylinder cowling

2

(supplies cold air over

1

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.

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.

IMPORTANT! In order to keep the function of the centrifugal cleaning, a continous maintenance and care must be made.

• Clean the air intake to the starter, the fan wings of the flywheel, the space around the flywheel, inlet pipe and carburetor space.

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 carburetor.

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.

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 0oC (32oF) or colder

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 (23oF) 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.
