TS 400
Allow only persons who understand this
Manual to operate your cut-off machine.
To receive maximum performance and
satisfaction from your STIHL cut-off
machine, it is important that you read
and understand the maintenance and
safety precautions, starting on page 3,
before using your cut-off machine.
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 cut-off machine is a high-
speed cutting tool, some special safety
precautions must be observed as with
any other cut-off machine 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 cut-off machine
differs from those described in this
Manual, please contact your STIHL
dealer for informations and assistance.
