Allow only persons who understand this
manual to operate your pole pruner.
To receive maximum performance and
satisfaction from your STIHL pole
pruner, it is important that you read and
understand the maintenance and safety
precautions, starting on page 3, before
using your pole pruner.
Contact your STIHL dealer or the STIHL
distributor for your area if you do not
understand any of the instructions in this
manual.
!Warning!
Because a pole pruner is a high-speed
cutting tool with a very long reach 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 pole pruner differ
from those described in this manual,
please contact your STIHL dealer for
information and assistance.
