c) 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.
d) 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.
e) 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.
f) 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.
g) 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.
h) 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.
i) Keep bystanders a safe distance away from work area. Anyone entering the work area must
wear personal protective equipment.
j) Fragments of workpiece or of a broken accessory may fly away and cause injury beyond
immediate area of operation.
k) 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.
l) Always hold the tool firmly in your hand(s) during the start-up.
m) The reaction torque of the motor, as it accelerates to full speed, can cause the tool to twist.
n) 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 dowel rods, pipes or tubing have a
tendency to roll while being cut, and may cause the bit to bind or jump toward you.
o) 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.
p) 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.
q) After changing the bits or making any 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 and loose rotating components will be violently thrown.
r) 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.
s) 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.
t) Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
u) Do not use accessories that require liquid coolants. Using water or other liquid coolants may
result in electrocution or shock.
v) Use completely unrolled and safe extension cords with a capacity of 5 Amps at least.
Kickback Safety
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.
a) 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.
b) 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.
c) Do not attach a toothed saw blade. Such blades create frequent kickback and loss of control.
d) Always feed the bit into the material in the same direction as the cutting edge is exiting
from the material (which is the same direction as the chips are thrown). Feeding the tool in
the wrong direction causes the cutting edge of the bit to climb out of the work and pull the tool in
the direction of this feed.

e) When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide cutters,
always have the work securely clamped. These wheels will grab if they become slightly canted
in the groove, and can kickback. When a cut-off wheel grabs, the wheel itself usually breaks. When
a rotary file, high-speed cutter or tungsten carbide cutter grabs, it may jump from the groove and
you could lose control of the tool.
Safety for Grinding and Abrasive
Cutting-off Operations
a) Use only wheel types that are recommended for your power tool and only for
recommended applications. For example: do not grind with the side of a cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels
may cause them to shatter.
b) For threaded abrasive cones and plugs use only undamaged wheel mandrels with an
unrelieved shoulder flange that are of correct size and length. Proper mandrels will
reduce the possibility of breakage.
c) Do not "jam" a 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 snagging of the wheel in the cut and the possibility of kickback or wheel breakage.
d) Do not position your hand in line with and behind the rotating wheel. When the wheel,
at the point of operation, is moving away from your hand, the possible kickback may propel the
spinning wheel and the power tool directly at you.
e) When wheel is pinched, snagged 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 pinching or snagging.
f) 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.
g) 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.
h) 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 for Wire Brush
Operation
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. Allow brushes to run at operating speed for at least one minute before using them.
During this time no one is to stand in front or in line with the brush. Loose bristles or wires
will be discharged during the run-in time.
c. Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire
fragments may be discharged at high velocity during the use of these brushes and may become
imbedded in your skin.
