Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
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-
trolled power 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 with both hands on the power tool
and position your body and arms to allow you to resist
kickback forces. Always use auxiliary handle, if pro-
vided, for maximum control over kickback or torque
reaction during startup. The operator can control
torque reactions or kickback 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, seg-
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety warnings specific for grinding and
cutting-off operations
Use only wheel types that are specified 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 specified 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 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.
A wheel intended for larger power tool is not suitable
for the higher speed of a smaller tool and may burst.
When using dual purpose wheels always use the cor-
rect guard for the application being performed. Failure
to use the correct guard may not provide the desired
level of guarding, which could lead to serious injury.
Additional safety warnings specific for cutting
off operations
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.
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 the wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold it
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 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.
