Kickback Safety Precautions; Safety Information - Shindaiwa 285s Manual Del Propietario - Operador

Kickback Safety
This saw is equipped with the following
safety equipment:
1. Inertia chain brake.
2. Low kick chain.
 Activating the chain brake tightens
a brake band around the chain drive
mechanism, stopping all chain rota-
tion. When sudden kickback occurs,
the chain break is automatically
actuated and the chain stops instantly.
The chain brake can also be activated
manually.
 Low-kick chain can significantly re-
duce the rotational force of kickback.
 Some bars are manufactured with a
reduced-radius (smaller) nose. This
special guide bar can reduce kick-
back by placing fewer cutters in the
kick-back zone.
WARNING!
To reduce the risk of kickback, all of
the above devices must be properly
installed and in good repair! Use
of other than ANSI B175.1- 2000
combinations may result in reduced
kickback protection!

Kickback Safety Precautions

Either of the following reactions could
cause you to lose control of your saw
while cutting, possibly resulting in seri-
ous injury!
1. Kickback can occur whenever the
guide bar nose or tip contact an
object while the saw is running. Tip
contact may cause the guide bar to
kick upward and back toward the op-
erator with a lightning-fast reaction!
. Pinching the saw along the top of
the guide bar may push the guide
bar rapidly back toward the opera-
tor! Pinching can occur whenever
wood closes in around the moving
chain!
Do not rely exclusively on the safety
devices incorporated with your saw.
As a chain saw user, observing the fol-
lowing steps will also help you to avoid
accident or injury on the job:

WARNING!
Brake engagement and operation
depend upon proper chain break
condition! For proper chain brake
testing and adjustment proce-
dures, see page 13.
WARNING!
 Sudden surprise can contribute to ac-
cidents! With a basic understanding of
kickback, you can reduce or eliminate
the element of surprise.
 Clear obstructions from the work
area before cutting. Remove any log,
branch, or other obstruction that
might contact the guide bar tip during
cutting operations.
 Grip the saw firmly with your right
hand on the rear handle and your left
hand on the front handle, thumbs
and fingers encircling the handles
whenever the saw is running. Don't let
go: A firm grip will help you to reduce
kickback while maintaining control of
the saw.
 Accelerate the saw before the chain
contacts the work area, and always
maintain high engine speeds through-
out the cut.
WARNING!
Kickback can
happen light-
ning-fast!
 Do not overreach or attempt to cut
above shoulder height.
 Follow the manufacturer's instruc-
tions for sharpening and mainte-
nance of the saw chain.
 Use only the replacement bar and
chain combinations specified by the
manufacturer.
 Never stand directly over the saw
while cutting!
 Use low-kickback chain, chain
brakes, or special guide bars to re-
duce the risk of kickback. Low kick-
back chain is chain that has met the
kickback performance requirements
of ANSI B175.1-000 (American
National Standard for Power Tools-
Gasoline Powered Chain Saws-Safety
requirements) when tested on the
representative sample of chain saws
below 3.8 c.i.d. specified in ANSI
B175.1-000.
