i) 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.
j) 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.
k) 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.
l) 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.
m) 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.
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.
t) 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.
