Adjustment of the oil pump

Heated handles (CS 2152 W)

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.

On the model CS 2152 W 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.

When the switch is pushed upwards, the heat is switched on. When it is pushed downwards the heat is switched off.

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.

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 tempera- ture of the exhaust demands efficient cooling of the engine and the catalytic converter unit.

Centrifugal cleaning ”Turbo”

Electrically heated carburetor (CS 2152 WH)

This chain saw is, if it has model code WH, equipped with electrically heated carburetor. The electrical heating prevents icing in the carburetor. A thermostat regulates heating so that the carburetor always has the correct temperature.

Winter use

During winter time, snow and cold weather can cause running problems, such as:

•Too low engine temperature.

•Icing of the air filter and freezing of the 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 using the heat from the cylinder.

Temperature 0°C (32°F) or colder:

The cylinder cover is made so it can be adjusted for running in cold weather. Open the winter flap so that preheated air from the cylinder can pass into the carburetor area preventing for instance icing of the air filter.

For temperatures below -5°C (23°F) and/or in snow

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.

conditions there is also:

•a special cover (A) for the starter housing,

•a winter plug (B) for the air intake that is fitted as shown.

These reduce the air flow and prevent large amounts of snow from being sucked into the carburetor chamber. NOTE! When the winter plug is fitted the winter flap must be open.

IMPORTANT! If the temperature rises above -5°C (23°F) or 0°C (32°F) respectively the saw MUST be restored to its normal settings. 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.
