SAFETY INSTRUCTIONS
Safety warnings common for grinding
a. This power tool is intended to function as a grinder.
Read all safety warnings, instructions, 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.
b. Operations such as wire brushing, cut-off, sanding and
polishing 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.
c. Do not use accessories which are not 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.
d. The rated speed of the accessory must be at least
equal to the maximum speed marked on the power tool.
Accessories running faster than their rated speed can
break and fly apart.
e. 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
guarded or controlled.
f. The arbour size of wheels, sanding drum 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.
g. Mandrel mounted wheels, sanding drums, cutters or
other accessories must be fully inserted into the collet or
chuck. The “overhang” or the length of the mandrel from
the wheel to the collet must be minimal. If the mandrel is
insufficiently held and/or the overhang of the wheel is too
long, the mounted wheel may become loose and ejected
at high velocity.
h. Do not use a damaged accessory. Before each use inspect
the accessory such as abrasive wheels for chips and
cracks, backing pad 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.
i. Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop 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.
j. 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.
k. Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring. 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 hands during the start-
up. The reaction torque of the motor, as it accelerates to full
speed, can cause the tool to twist.
m. 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 both hands 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.
n. 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.
o. 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, loose rotating
components will be violently thrown.
p. 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.
q. 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.
r. Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
s. 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,
backing pad, 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 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 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. 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. 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 saw chain woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss
of control.
d. Always feed the bit into the material in the same direction
