MAINTENANCE

”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.

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.

Heated handles

(346XPG, 353G)

On models with the model code XPG/G 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 carburetor heating

(346XPG, 353G)

If this chain saw is marked with Carburetor Heating 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

Running problems can occur when using the machine in the cold and snowy conditions caused by:

•Too low engine temperature.

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

Temperature 0°C (32°F) or colder:

A special winter kit, including necessary parts and assembly instructions, is available for using the machine in cold temperatures.

345e: Before usage a hole is made in the cylinder cover and a winter flap is fitted (see illustration below).

346XP, 353: 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.

For temperatures below -5°C (23°F) and/or in snow conditions there is also:

•a special cover (A) for the starter housing

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

These reduce the flow of cooling air and prevent large amounts of snow from being sucked into the carburetor space.

For further information see assembly instructions for the winter kit.

CAUTION! 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 machine MUST be restored to its normal set-up. Otherwise there is a risk of overheating, which can cause severe engine damage.
