Allow only persons who fully understand
this manual to operate your chain saw.
To receive maximum performance and

it is important that you read, understand
and follow the safety precautions and
the operating and maintenance
instructions in chapter "Safety
Precautions and Working Techniques"
before using your chain saw. For further

wood-cutting tool, some special safety
precautions must be observed as with
any other power saw to reduce the risk
of personal injury. Careless or improper
use may cause serious or even fatal
injury.
