Allow only persons who understand this
Manual to operate your mistblower.
To receive maximum performance and
satisfaction from your STIHL mistblower,
it is important that you read and
understand the maintenance and safety
precautions, starting on page 3, before
using your mistblower.
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 mistblower is a tool for
spraying chemicals, some special safety
precautions must be observed as with
any other power tool 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 improvements
are made from time-to-time. If the
operating characteristics or the
appearance of your mistblower differs
from those described in this Manual,
please contact your STIHL dealer for
information and assistance.
