General safety instructions
WARNING: Read the warning instructions

A chainsaw is a dangerous tool if used carelessly or
incorrectly and can cause serious injury or death. It
is very important that you read and understand the
contents of this operator’s manual.
Under no circumstances may the design of the
product be modified without the permission of the
manufacturer. Do not use a product that appears to
have been modified by others and only use
accessories recommended for this product. Non-
authorized modifications and/or accessories can
result in serious personal injury or the death of the
operator or others.
The inside of the muffler contain chemicals that may
be carcinogenic. Avoid contact with these elements
in the event of a damaged muffler.
Long term inhalation of the engine’s exhaust fumes,
chain oil mist and sawdust can represent a health
risk.
This product produces an electromagnetic field
during operation. This field may under some
circumstances interfere with active or passive
medical implants. To reduce the risk of serious or
fatal injury, we recommend persons with medical
implants to consult their physician and the medical
implant manufacturer before operating this product.
The information in this operator's manual is never a
substitute for professional skills and experience. If
you get into a situation where you feel unsafe, stop
and seek expert advice. Contact your servicing
dealer or an experienced chainsaw user. Do not
attempt any task that you feel unsure of!
