MAINTENANCE

Centrifugal cleaning “Turbo”

Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan.

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 carburettor compartment.

Heated handles (CS 2147W, CS 2152W)

On models with the model code W, both the front handle bar and the rear handle are equipped with electrical heating coils. These are supplied with electricity from a generator built into the chain saw.

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

Electrical carburettor heating (CS 2147WH, CS 2152WH)

If this chain saw has the model code WH then it is equipped with an electrically heated carburettor. The electrical heating prevents icing in the carburettor. A thermostat regulates heating so that the carburettor always has the correct working temperature.

Winter use

During cold weather and under powder snow conditions, operating problems can arise due to:

•Too low engine temperature.

•Icing of the air filter and carburettor. Special measures are therefore often required:

•Partly mask the air inlet on the starter to increase the working temperature of the engine.

Preheat the intake air to the carburettor by using the heat from the cylinder.

Temperature 0° C 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 carburettor space preventing icing of the air filter, etc.

Temperature -5°C or colder:

For running the machine in cold weather or powder snow, a special cover is available, which is mounted on the starter housing. This reduces the intake of cold air and prevents large amounts of snow from being sucked in.

CAUTION! When the winter plug is fitted the winter flap must be open!

CAUTION! If the special winterising kit has been fitted or any measures have been taken to increase the temperature these changes must be reversed before the machine is used in normal temperature conditions. Otherwise there is a risk of overheating, resulting in severe damage to the engine.

IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
