Because an earth auger is a high-
torque, gasoline-powered 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.
STIHL’s philosophy is to continually
improve all of its products. As a result,
engineering changes and improve-
ments are made from time to time. If
the operating characteristics or the
appearance of your earth auger
differs from those described in this
manual, please contact your STIHL
dealer for information and assistance.
