air entering the carburettor to be first warmed by the engine
to increase the efficiency of the operation.

Operation
WARNINGS.
• Always follow the safety instructions given at the front
of this manual. This chain saw must only be used for
cutting wood. It must not be used for cutting other types
of material. Do not use the chain saw as a lever for lifting,
moving or splitting objects.
• Do not attach the chain saw to a fixed stand.
• Do not attach any devices to the chain saw other than
those specified by the manufacturer.
Helpful hints
• Do not force the saw into the cut. Apply only light pressure
whilst running the engine at full throttle.
• If the saw chain gets caught in the cut, do not try to
remove it by twisting the guide or pulling forcibly. Use a
lever or wedge to open up the cut so that the saw chain
is freed.
