•
Position the cord clear of the spinning acces-
sory.
If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
•
Never lay the power tool down until the acces-
sory has come to a complete stop.
The spinning
accessory may grab the surface and pull the power
tool out of your control.
•
Do not run the power tool while carrying it at
your side.
Accidental contact with the spinning
accessory could snag your clothing, pulling the ac
-
cessory into your body.
•
Regularly clean the power tool’s air vents.
The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
•
Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
•
Do not use accessories that require liquid cool-
ants.
Using water or other liquid coolants may result
in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power tool
to be forced in the direction opposite of the ac
-
cessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into the
surface of the material causing the wheel to climb
out or kick out. The wheel may either jump toward
or away from the operator, depending on direction of
the wheel’s movement at the point of pinching. Abra
-
sive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or in
-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below.
•
Maintain a firm grip on the power tool and posi
-
tion your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if
provided, for maximum control over kickback
or torque reaction during start-up.
The operator
can control torque reactions or kickback forces, if
proper precautions are taken.
•
Never place your hand near the rotating acces-
sory.
Accessory may kickback over your hand.
•
Do not position your body in the area where
power tool will move if kickback occurs.
Kickback
will propel the tool in direction opposite to the wheel’s
movement at the point of snagging.
•
Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the ac-
cessory.
Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause
loss of control or kickback.
•
Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent
kickback and loss of control.
Safety Warnings Specific for Grinding and Abra
-
sive Cutting-Off Operations:
•
Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel.
Wheels for which the
power tool was not designed cannot be adequately
guarded and are unsafe.
•
The grinding surface of centre depressed wheels
must be mounted below the plane of the guard
lip.
An improperly mounted wheel that projects
through the plane of the guard lip cannot be ad
-
equately protected.
•
The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed towards
the operator.
The guard helps to protect the opera
-
tor from broken wheel fragments, accidental contact
with wheel and sparks that could ignite clothing.
•
Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel.
Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied
to these wheels may cause them to shatter.
•
Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
•
Do not use worn down wheels from larger power
tools.
Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
may burst.
Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
•
Do not “jam” the cut-off wheel or apply ex-
cessive pressure. Do not attempt to make an
excessive depth of cut.
Overstressing the wheel
increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibility
of kickback or wheel breakage.
•
Do not position your body in line with and behind
the rotating wheel.
When the wheel, at the point
of operation, is moving away from your body, the
possible kickback may propel the spinning wheel
and the power tool directly at you.
•
When wheel is binding or when interrupting a
cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur.
Investigate and take corrective action to
eliminate the cause of wheel binding.
•
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut.
The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece."
•
Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back.
Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of
the workpiece on both sides of the wheel.
•
Use extra caution when making a “pocket cut”
into existing walls or other blind areas.
The pro
-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
•
Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper.
Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing
of the disc or kickback.
