Kickback safety precautions
Kickback from the material being cut may be generated
due to the cutting position, and this may cause loss of
control of the machine. This may cause the cutting
wheel to touch the operator, resulting in serious injury.
Rotational kickback
Cutting with the upper part of
the cutting wheel generates
kickback from the material
being cut; this causes the tip
of the cutting wheel to kick
back from the rotation and is
extremely dangerous. Always cut with the bottom of the cut-
ting wheel.
Linear kickback
When cutting with the bottom
of the cutting wheel, the ma-
chine may generate a force
that pulls the machine for-
ward. Always hold the handle
firmly while working.
Either or these reactions may cause you to lose control of
the cut-off saw and come in contact with the moving wheel,
which could result in serious personal injury. As a cut-off
saw user, you should take several steps to keep your cutting
jobs free from accident or injury.
With a basic understanding of kickback, you can reduce or
eliminate the element of surprise. Sudden surprise contrib-
utes to accidents. Understand that rotational kickback is pre-
ventable by keeping the upper side of the cutting wheel from
touching an object.
DANGER
Do not operate a cut-off saw with one hand! Serious injury
to the operator, helpers or bystanders may result from one-
handed operation. For proper control, always use two hands
when operating a cut-off saw, one of which operates the trig-
ger. Otherwise, this can result in the cut-off saw "skating" or
skidding, which can result in personal injury due to loss of
control.
Keep a good firm grip on the cut-off saw which both hands,
with the right hand on the rear handle and the left hand on
the front handle, when the unit is running. Use a firm grip
with thumbs and fingers encircling the cut-off saw handles.
A firm grip will help you reduce kickback and maintain con-
trol of the saw. Two hands must be used to control the saw
at all times.
Make sure that the area in which you are cutting is free from
obstructions. Do not let the upper side of the cutting wheel
contact a log, branch, or any other obstruction which could
be hit while you are operating the saw.
Cutting at high speeds may reduce the likelihood of kick-
back. But cutting at part-throttle or low speeds may be pref-
erable to control the cut-off saw in tight situations and may
also reduce the likelihood of kickback.
