this manual. If the operating
characteristics or the appearance of
your machine differs from those

Safety Precautions and
Working Techniques
Because an earth auger
is a high-torque, gaso-
line-powered tool, some
special safety precau-
tions must be observed to
reduce the risk of per-
sonal injury.
It is important that you
read, fully understand
and observe the following
safety precautions and
warnings. Read the
instruction manual and
the safety precautions
periodically. Careless or
improper use may cause
serious or fatal injury.
Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable federal, state and local safety
regulations, standards and ordinances.
DANGER
Drilling into or contact
with electrical wires may
cause severe shock,
burns or death. See the
section "Working Condi-
tions" below.
WARNING
Striking a hard object in the earth with
the turning drill and the resulting slowing
or stopping of the auger creates reactive
forces. The transfer of rotational
(reactive) forces can cause the auger
powerhead and handles to rotate
suddenly in a counterclockwise direction
