Allow only persons who fully understand
the manuals of the MultiEngine and the
MultiTool to operate your power tool.
To receive maximum performance and
satisfaction from your STIHL power tool,
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 power tool. For further
information you can go to
www.stihlusa.com.
Contact your STIHL dealer or the STIHL
distributor for your area if you do not
understand any of the instructions in the
two manuals.
WARNING
Because this MultiEngine is the engine
for a high-speed power tool, some
special safety precautions must be
observed to reduce the risk of personal
injury. Careless or improper use may
cause serious or even fatal injury.
Make sure your unit is equipped with the
proper deflector for the type of cutting
attachment being used. Always wear
proper eye protection.
