GENERAL SAFETY PRECAUTIONS
12 – English
Cutting equipment designed to reduce
kickback
The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything.
By using cutting equipment with ”built-in” kickback reduction
and keeping the chain sharp and well-maintained you can
reduce the effects of kickback.
Bar
The smaller the tip radius the lower the chance of kickback.
Chain
A chain is made up of a number of links, which are available
in standard and low-kickback versions.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment, you
should replace a worn or damaged bar or chain with a bar
and chain combinations recommended by Husqvarna. See
instructions under the heading Technical Data for a list of
replacement bar and chain combinations we recommend.

Number of teeth on bar tip sprocket (T).
Chain pitch (inches). The spacing between the drive links
of the chain must match the spacing of the teeth on the
bar tip sproc
ket and drive sprocket.
Number of drive links. The number of drive links is
deter
mined by the length of the bar, the chain pitch and
the number of teeth on the bar tip sprocket.

General information on sharpening cutting teeth
Never use a blunt chain. When the chain is blunt you
have to exert more pressure to force the bar through the
wood and the chips will be very small. If the chain is very
blunt it will produce wood powder and no chips or
shavings.
A sharp chain eats its way through the wood and
produces long, thic
k chips or sha
vings.
!
WARNING! Faulty cutting equipment or the
wrong combination of bar and saw chain
increases the risk of kickback! Only use the
bar/saw chain combinations we
recommend, and follow the filing
instructions. See instructions under the
heading Technical data.
IMPORTANT! No saw chain design eliminates the danger
of kickback.
!
WARNING! Any contact with a rotating saw
chain can cause extremely serious injuries.
