k) Position the cord clear of the spinning accessory. If you lose control,
the cord may be cut or snagged and your hand or arm may be pulled into the
spinning accessory.
l) Never lay the power tool down until the accessory has come to a
complete stop. The spinning accessory may grab the surface and pull the
power tool out of your control.
m) Do not run the power tool while carrying it at your side. Accidental
contact with the spinning accessory could snag your clothing, pulling the
accessory into your body.
n) 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.
o) Do not operate the power tool near flammable materials. Sparks
could ignite these materials.
p) Do not use accessories that require liquid coolants. 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. Pinching
or snagging causes rapid stalling of the rotating wheel which in turn causes the
GB
uncontrolled power tool to be forced in the direction opposite of the wheel'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. Abrasive wheels may also break
under these conditions.
Kickback is the result of saw misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position 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.
b) Never place your hand near the rotating accessory. Accessory may
kickback over your hand.
c) 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.
d) 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 accessory. Corners,
sharp edges or bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback.
e) 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 Abrasive Cutting-Off
Operations:
a) 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.
b) The guard must be securely attached to the power tool and
positioned for maximum safety, so the least amount of cut-off wheel
is exposed towards the operator. The guard helps to protect operator from
broken cut-off wheel fragments and accidental contact with cut-off wheel.

c) 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.
d) 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.
e) 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:
a) Do not "jam" the cut-off wheel or apply excessive 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.
b) 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.
c) 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.
d) Do not restart the cutting operation in the workpiece. Let the
wheel reach full speed and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to minimize the risk of
wheel pinching and kickback. 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.
f) Use extra caution when making a "pocket cut" into existing walls
or other blind areas. The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
a) 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.
Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even during
ordinary operation. Do not overstress the wires by applying excessive
load to the brush. The wire bristles can easily penetrate light clothing and/
or skin.
b) If the use of a guard is recommended for wire brushing, do not
allow any interference of the wire wheel or brush with the guard.
Wire wheel or brush may expand in diameter due to work load and centrifugal
forces.
