illustrations and specifications provided with this
power tool. Failure to follow all instructions listed
below may result in electric shock, fire and / or serious
injury�
• Operations such as sanding, wire brushing,
polishing or cutting-off are not recommended to
be performed with this power tool. Operations for
which the power tool was not designed may create a
hazard and cause personal injury�
• Do not use accessories
specifically designed and recommended by the
tool manufacturer. Just because the accessory can
be attached to your power tool, it does not assure safe
operation�
• The rated speed of the grinding accessories
must be at least equal to the maximum speed
marked on the power tool. Grinding accessories
running faster than their rated speed can break and
fly apart.
• The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot
be adequately controlled�
• The arbour size of wheels, sanding drums or
any other accessory must properly fit the spindle
or collet of the power tool. Accessories that do not
match the mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause loss
of control�
• Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully inserted
into the collet or chuck. If the mandrel is insufficiently
held and / or the overhang of the wheel is too long, the
mounted wheel may become loose and be ejected at
high velocity�
• Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive wheels
for chips and cracks, sanding drum for cracks, tear
or excess wear, wire brush for loose or cracked
wires. If power tool or accessory is dropped,
inspect for damage or install an undamaged
accessory. After inspecting and installing an
accessory, position yourself and bystanders away
from the plane of the rotating accessory and run
the power tool at maximum no-load speed for one
minute. Damaged accessories will normally break
apart during this test time�
• Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various operations.
The dust mask or respirator must be capable of
filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause
hearing loss�
• Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation�
• Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring or its
own cord. Cutting accessory contacting a "live" wire
may make exposed metal parts of the power tool "live"
and could give the operator an electric shock�
• Always hold the tool firmly in your hand(s)
during the start-up. The reaction torque of the motor,
as it accelerates to full speed, can cause the tool to
twist�
• Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one
hand and the tool in the other hand while in use.
Clamping a small workpiece allows you to use your
hand(s) to control the tool� Round material such as
which are not
dowel rods, pipes or tubing have a tendency to roll
while being cut, and may cause the bit to bind or jump
toward you�
• Position the cord clear
accessory. 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
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull the
power tool out of your control�
• After
adjustments, make sure the collet nut, chuck or any
other adjustment devices are securely tightened.
Loose adjustment devices can unexpectedly shift,
causing loss of control, loose rotating components will
be violently thrown�
• 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�
• 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
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, sanding band, 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 accessory's rotation�
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 power tool misuse and / or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below�

changing the
• Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can control
kickback forces, if proper precautions are taken�
• 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�
