Kickback Safety Features - Poulan Pro 1420 Instruction Manual

• A good, firm grip on the saw with both
hands will help you maintain control.
Don't let go. Grip the rear handle with
your right hand whether you are right or
left handed. Wrap the fingers of your left
hand over and around the front handle-
bar, and your left thumb under the front
handlebar. Keep your left arm straight
with the elbow locked.
• Position your left hand on the front
handlebar so it is in a straight line with
your right hand on the rear handle
when making bucking cuts. Stand
slightly to the left side of the saw to
keep your body from being in a direct
line with the cutting chain.
• Stand with your weight evenly bal-
anced on both feet.
• Do not overreach. You could be drawn
or thrown off balance and lose control.
• Do not cut above shoulder height. It is
difficult to maintain control of saw
above shoulder height.
KICKBACK SAFETY FEATURES
_/L WARNING: The following features
are included on your sawto help reduce
hazard of kickback; however, such fea-
tures will not totally eliminate this dan-
ger. Do not rely only on safety devices.
• Hand Guard: designed to reduce the
chance of your left hand contacting
the chain if your hand slips offthe front
handlebar.
• Position of front and rear handlebars:
designed with distance between han-
dles and "in-line" with each other. The
spread and "in-line" position of the
hands provided by this design work to-
gether to give balance and resistance
in controlling the pivot of the saw back
toward the operator if kickback oc-
curs.
• Reduced-Kickback Guide Bar: de-
signed with a small radius tip which re-
duces the size of the kickback danger
zone on the bar tip. This type bar has
been demonstrated to significantly re-
duce the number and seriousness of
kickbacks when tested in accordance
with ANSI B175.1.

_WARNING: Computed Kickback
Angle (CKA) listed on your saw and listed
in the following CKA Table represents the
angle of kickback your bar and chain
combinations will have when tested in ac-
cordance with CSA and ANSI standards.
Computed angles represented in the CKA
column indicate total energy and angle
associated without a chain brake. When
purchasing replacements, considerations
should be given to the lower CKA values.
In all cases, lower CKA values represent a
safer operating environment for the user.
• Tip contact in some cases may cause
a lightning fast REACTION, kicking the
guide bar up and back toward the op-
erator.
• Pinching the saw chain along the tip of
the guide bar may push the guide bar
rapidly back towards the operator.
• Either of these reactions may cause
you to lose control of the saw which
could result in serious injury. Do not
rely exclusively upon safety devices
built into your saw.
The following guide bar and chain com-
binations meet kickback requirements of
CSA Z62.1 & Z62.3 and ANSI B175.1
when used on saws listed in this manual.
Use of bar and chain combinations other
than those listed is not recommended and
may not meet the CKA requirements per
standard.
