i) 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 shock the operator.
j) 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.
k) 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.
l) 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.
m)Regularly clean the power tool's air vents. The motorʼs fan will draw the dust
inside the housing and excessive accumulation of powdered metal may cause
electrical hazards.
n) Do not operate the power tool near flammable materials. Sparks could ignite
these materials.
o) Do not use accessories that require liquid coolants. Using water or other
liquid coolants may result in electrocution or shock.
p) Do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate
accessories can result in injury.
q) Always use side handle. Tighten the handle securely. The side handle should
always be used to maintain control of the tool at all times.
r) Use clamps or another practical way to secure and support the work piece to
a stable platform. Holding the work by hand or against your body leaves it
unstable and may lead to loss of control.
Further safety instructions for all operations
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 accessoryʼs 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 wheelʼs
movement at the point of pinching. Abrasive wheels may also break under these
conditions.
Kickback is the result of 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 reaction or kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating accessory. Accessory may kickback
over your hand.
c) 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
wheelʼs movement at the point of snagging.
d) 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.
e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such
blades create frequent kickback and loss of control.
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations
a) Use only wheel types that are recommended 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.
b) 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 and
accidental contact with wheel.

c) Wheels must be used only for recommended 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.
d) Always use undamaged wheel flanges that are of correct size and shape for
your selected wheel. Proper wheel flanges support the wheel thus reducing the
possibility of wheel breakage. Flanges for cut-off wheels may be different from
grinding wheel flanges.
e) Do not use worn down wheels from larger power tools. Wheel intended for
larger power tool is not suitable for the higher speed of a smaller tool and may
burst.
Additional Safety Warnings Specific for Abrasive Cutting-Off Operation
a) Do not "jam" the cut-off wheel or apply excessive pressure. Do not attempt
to make an excessive depth of cut. Over stressing 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.
b) Do not position your body in line with and behind the rotating wheel. When
the wheel, at the point of operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power tool directly at you.
c) When wheel is binding 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 binding.
d) Do not restart the cutting operation in the workpiece. Let the wheel reach
full speed and carefully reenter the cut. The wheel may bind, walk up or
kickback if the power tool is restarted in the workpiece.
e) 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.
f) 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 Specific for Sanding Operations
a) Do not use excessively oversized sanding disc paper. Follow manufacturers
recommendations, when selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
Safety Warnings Specific for Wire Brushing Operations
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) If the use of a guard is recommended for wire brushing, do not allow any
interference of the wire wheel or brush with the guard. Wire wheel or brush
may expand in diameter due to work and centrifugal forces.
Additional Safety Information
• Do not use Type 1 flat abrasive or diamond wheels without proper Type 1 guard.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask if operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
