Allow only persons who understand this
manual to operate your earth auger.
To receive maximum performance and
satisfaction from your STIHL earth
auger, it is important that you read and

precautions, starting on page 3, before
using your earth auger.
Contact your STIHL dealer or the STIHL
distributor for your area if you do not

special safety precautions must be
observed to reduce the risk of personal
injury.
Careless or improper use may cause
serious or even fatal injury.
