• Never place your hand near the rotating acces-

sory. Accessory may kick back over your hand.

• Do not position your body in the area where

power tool will move if kickback occurs. Kick-

back will propel the tool in direction opposite to

the wheel’s movement at the point of snagging.

• 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.

• Do not attach a saw chain woodcarving blade

or toothed saw blade. Such blades create fre-

quent kickback and loss of control.

Safety Warnings Specific for Grinding and

Abrasive Cutting-Off Operations:

• Use only wheel types that are recommended

for your power tool and the speciﬁ c guard

designed for the selected wheel. Wheels for

which the power tool was not designed can not

be adequately guarded and are unsafe.

• The guard must be securely attached to the

power tool and positioned for maximum

safety, so the least amount of wheel is ex-

posed towards the operator. The guard helps

to protect operator from broken wheel fragments

and accidental contact with wheel.

• 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.

• Always use undamaged wheel ﬂ anges that are

of correct size and shape for your selected

wheel. Proper wheel ﬂ anges support the wheel

thus reducing the possibility of wheel breakage.

Flanges for cut-off wheels may be different from

grinding wheel ﬂ anges.

• 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 Speciﬁ c for Abra-

sive Cutting-Off Operations:

• Do not jam the cut-off wheel or apply exces-

sive pressure. Do not attempt to make an

excessive depth of cut. Overstressing the wheel

increases the loading and susceptibility to twisting

or binding of the wheel in the cut and the possibil-

ity of kickback or wheel breakage.

• 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 spin-

ning wheel and the power tool directly at you.

• 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 cor-

rective action to eliminate the cause of wheel

binding.

• 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.

• Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick-

back. 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.

• Use extra caution when making a "pocketcut"

into existing walls or other blind areas. The

protruding wheel may cut gas or water pipes, elec-

trical wiring or objects that can cause kickback.

Safety Warnings Speciﬁ c for Sanding Opera-

tions:

• Do not use excessively oversized sanding disc

paper. Follow manufacturers recommenda-

tions, 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 Speciﬁ c for Wire Brushing

Operations:

• Be aware that wire bristles are thrown by the

brush even during ordinary operation. Do not

over stress the wires by applying excessive

load to the brush. The wire bristles can easily

penetrate light clothing and/or skin.

• 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 workload

and centrifugal forces.

Additional Safety Warnings

• Maintain labels and nameplates. These carry

important information. If unreadable or missing,

contact a MILWAUKEE service facility for a free

replacement.

• WARNING: Some dust created by power sanding,

sawing, grinding, drilling, and other construction

activities contains chemicals known to cause

cancer, birth defects or other reproductive harm.

Some examples of these chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-treated

lumber.

Your risk from these exposures varies, depending

on how often you do this type of work. To reduce

your exposure to these chemicals: work in a well

ventilated area, and work with approved safety

equipment, such as those dust masks that are

specially designed to ﬁ lter out microscopic par-

ticles.
