Causes And Operator Prevention Of Kickback; Kickback Safety Devices On This Saw; Chain Brake - Oregon CS300 Manual De Instrucciones

OREGON® Cordless Tool System
CHAIN SAW MODEL CS300
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 upon 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 or
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.
• Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause chain
breakage and/or kickback.
AA 1214 - F/N 573259
• Follow the manufacturer's 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 . 5) . 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. 5
CHAIN
This saw comes equipped with a saw
chain that met the reduced kickback
requirements of ANSI B175 . 1 when tested
on a representative sample of chain saws .
For replacement chain, see "Specifications
and Components" in this manual .
