1 1 . Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
1 2. Never lay the po w er tool do w n until the acces-
sory has come to a complete stop. T h e spinning
accessory may grab the surface and pull the
power tool out of your control.
1 3. Do not run the po w er tool w hile carrying it at your side.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body.
1 4 . Regularly clean the po w er tool's air vents. T h e
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
1 5 . Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
1 6 . 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 acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled 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
d irec tion of th e w h eel' s mov ement at th e point of pinc h ing.
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.
Maintain a firm grip on the power tool and
1 .
position your body and arm to allo w you to
resist kickback forces. Al w ays use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back forces, if proper precautions are taken.
2. Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
3. Do not position your body in the area w here
po w er tool w ill move if kickback occurs.
Kickback will propel the tool in direction opposite
to t h e w h eel ' s mo v ement at t h e point o f snagging.
4 . Use special care w hen w orking 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.
5 . Do not attach a sa w chain w oodcarving blade
or toothed sa w blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for rinding and Abrasive
Cutting-Off Operations:
1 . Use only w heel types that are recommended
for your power tool and the specific guard
designed for the selected w heel. W h eels f or
which the power tool was not designed cannot be
adequately guarded and are unsafe.
2. The grinding surface of centre depressed
w heels must be mounted belo w the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.
3. The guard must be securely attached to the
pow er tool and positioned for maximum safety,
so the least amount of w heel is exposed tow ards
the operator. The guard helps to protect the opera-
tor from broken wheel fragments, accidental contact
with wheel and sparks that could ignite clothing.
4 . Wheels must be used only for recommended
applications. For example: do not grind w ith the
side of cut-off w heel. Abrasive cut-off wheels are
inten d e d f or perip h eral grin d ing, si d e f or c es applie d
to these wheels may cause them to shatter.
Always use undamaged wheel anges that are of
5 .
correct size and shape for your selected w heel.
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.
6 . Do not use w orn do w n w heels from larger po w er
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 Operations:
1 . Do not " jam " the cut-off w heel or apply excessive
pressure. Do not attempt to make an excessive depth
of cut. O v erstressing t h e w h eel in c reases t h e loa d ing an d
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
2. Do not position your body in line w ith and
behind the rotating w heel. W h en t h e w h eel, 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.
3. When w heel is binding or w hen interrupting
a cut for any reason, s w itch off the po w er
tool and hold the po w er tool motionless until
the w heel comes to a complete stop. Never
attempt to remove the cut-off w heel from the
cut w hile the w heel is in motion other w ise
kickback may occur. I n v estigate an d take c orre c -
tive action to eliminate the cause of wheel binding.
4 . Do not restart the cutting operation in the w ork-
piece. Let the w heel 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.
5 . Support panels or any oversized w orkpiece to
minimize the risk of w heel 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.
6 . Use extra caution w hen making a " pocket cut "
into existing w alls or other blind areas. T h e
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
1 . Do not use excessively oversized sanding
disc paper. Follo w manufacturers recommen-
dations, w hen 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.
