Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in elec-
trocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolledpower tool to be forced in the direction oppo-
site of the accessory'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 oper-
ator, 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 power tool misuse and/or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
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 kick-
back forces, if proper precautions are taken.
Never place your hand near the rotating accessory.
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 accessory. Cor-
ners, sharp edges or bouncing have a tendency to snag
the rotating accessory and cause loss of control or kick-
back.
Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kick-
back 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 adequately 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 operator from broken wheel
fragments, accidental contact with wheel and sparks
that could ignite clothing.
Wheels must be used only for recommended applica-
tions. For example: do not grind with the side of cut-off
wheel. Abrasive cut-off wheels are intended for periph-
eral grinding; side forces applied to these wheels may
cause them to shatter.
Always use undamaged wheel flanges that are of cor-
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the pos-
sibility 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 excessive pres-
sure. Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and sus-
ceptibility 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 oper-
ation, 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 com-
plete 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 kickback. Large work-
pieces 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 protruding
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 select-
ing 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 oper-
ations
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.
