and specialized
training for dealing with kickback.
STIHL
recommends the
use
of its
green
labeled redu-
ced kickback bars, green labeled low kickback chains
and a STIHL Quickstop chain brake for both
experien-
ced and inexperienced chain
saw
users.
Please ask your STIHL
dealer to properly match your po-
werhead with the appropriate bar/chain combinations to
reduce the risk of
kickback injury. Green labeled bars and
chains
are
recommended for all powerheads. See
your
"STIHL Bar and Chain
Information" leaflet for details.
Warning!
Use of other,
non-listed bar/chain combinations
may
increase
kickback forces and increase the risk of kick-
back injury.
New
bar/chain combinations may be developed after pu-
blication of this literature, which will, in combination
with
certain powerheads,
comply with § 4.12 of ANSI B 175.1
1985. Check
with your STIHL dealer for such combina-
tions.
Bow Guides
Warning! Any chain saw equipped
with
a
bow guide is po-
tentially
very
dangerous.
Improper
use can
result in
kick-
back,
pushback or
pull-in, and
very serious
injury
or
death.
Only
thoroughly
instructed
and
experienced
operators
should
use a
chain saw equipped
with
a
bow
guide.
A bow guide
(or
bow bar) is
a
specially designed substitu-
tion for a regular guide bar. Like a regular guide bar, it
supports and guides the saw chain. Unlike a regular guide
bar, it consists
of a narrow rail structure with a large open
space in the
middle.
Warning! The
risk of kickback
is increased with
a
bow
guide because of the increased kickback contact
area.
STIHL recommends the use of the STIHL Quickstop chain
brake. Low kickback chain will not
significantly reduce
the risk of kickback injury when
used on a bow guide.

Guard
Only STIHL
bow
guides
are
approved for use with STIHL
powerheads. The
use
of other bow guides with
a
STIHL
powerhead can be hazardous to the operator due to
the
absence of safety guards
and spurs and necessary un-
authorized modifications needed to mount the bow guide
to
the STIHL powerhead.
Do
not use a
STIHL bow
guide
on any powerhead except
a STIHL
powerhead. Unauthorized combinations
are
dan-
gerous.
Never attempt to operate a chain saw equipped
with a
bow guide unless the
spurs
and both
guards are in place
(ill. 13). Under
no
circumstances
should
any
of the
spurs or
guards be removed. Keep the
nuts which hold these items
in place tightened at all times.
The
guards
at
the
top
and bottom of the bow guide are re-
quired
to
reduce the
possibility of injury caused by
contact
with the
chain. These guards
are
slotted
to
allow
position-
ing as close to the powerhead as possible. After the bow
guide is mounted on the chain saw, slide the guards as
close to the
powerhead
as
possible.
