Causes And Operator Prevention Of Kickback; Kickback Safety Devices On This Saw; Chain Brake - Oregon CS1500-091 Manual Original De Instrucciones

SAFETY RULES
CAUSES AND OPERATOR
PREVENTION OF KICKBACK
Kickback may occur when the nose or tip of
the guide bar touches an object, or when
the wood closes in and pinches the saw
chain in the cut
Tip contact, in some cases, may cause a
sudden reverse reaction, kicking the guide
bar up and back towards the operator
Pinching the saw chain along the top 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 personal injury Do not rely
exclusively on the safety devices built into
your saw As a chain saw user, you should
take several steps to keep your cutting jobs
free from accident and injury
Kickback is the result of tool misuse and/
or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:
• Maintain a firm grip with thumbs
and fingers encircling the chain saw
handles, with both hands on the saw
and position your body and arm to
allow you to resist kickback forces.
Kickback forces can be controlled by the
operator , if proper precautions are taken.
Do not let go of the chain saw.
• Do not overreach and do not cut
above shoulder height. This helps
prevent unintended tip contact and
enables better control of the chain saw in
unexpected situations.
• Follow the OREGON® sharpening and
maintenance instructions for the saw
chain. Decreasing the depth gauge height
can lead to increased kickback.

KICKBACK SAFETY
DEVICES ON THIS SAW
DANGER: NEVER MODIFY OR ATTEMPT
TO DISABLE THE CHAIN BRAKE.
DANGER: ONLY USE REPLACEMENT
BARS AND CHAINS SPECIFIED BY
OREGON®. Incorrect replacement bars
and chains may cause chain breakage and
increased risk of kickback injury.

CHAIN BRAKE

This chain saw comes equipped with a
chain brake, which stops both the motor
and the motion of the chain when kickback
occurs (Fig 4) The chain brake can be
activated by the forward motion of the
front hand guard as the saw rotates
backward during kickback; it can also be
activated by the inertial forces generated
from a kickback event
FIG. 4
CHAIN
This chain saw comes equipped with a
saw chain that met the reduced kickback
performance requirements of the American
National Standards Institute (ANSI) and
Canadian Standards Association (CSA),
ANSI B175 1 and CSA Z62 3 respectively,
when tested according to the provisions of
the standards For replacement chain, see
