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.
