Warning!
To reduce the risk of loss of control, be
sure that the earth auger brake is
engaged before starting. Because the
engine speed at starting throttle is fast
enough for the clutch to drive the drilling
tool, the tool will turn unless the auger
brake is engaged.
!
Warning!
When you pull the starter grip, don't
wrap the starter rope around your
hands. Do not allow the grip to snap
back, but guide the starter rope slowly to
permit the rope to rewind properly.
Failure to follow this procedure may
result in injury to hand or fingers and
may damage the starter mechanism.
Important Adjustments
!
Warning!
At correct idle speed, the drilling tool
should not rotate. For directions to
adjust idle speed, see the appropriate
section of your owner's manual. To
reduce the risk of injury from a turning
drilling tool do not use an earth auger
with incorrect idle speed adjustment.

If you cannot set the correct idle speed,
have your STIHL dealer check your
earth auger and make proper
adjustments or repairs.
Working Conditions
Striking something hard in
the earth, such as a rock
or gravel, may cause the
drilling tool to slow down
suddenly or stop. In such
a situation, some or all of
the rotational force (reactive force) is
transferred to the powerhead and
handle frame of the earth auger which
can cause the auger powerhead and
handles to rotate suddenly in a
counterclockwise direction.
!
Warning!
Work carefully in rocky ground or where
other solid objects may be present.
Keep throttle feed pressure to a
minimum. If you feel or hear the drilling
tool strike a solid object, release the
throttle trigger immediately and remove
the object before drilling is continued.
When drilling in heavy clay soil, bore
about 1/3 way and remove the auger
from the hole. Clean off auger then
continue in slow steps frequently
clearing drill.
