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 WARNINGS SPECIFIC 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 SPECIFIC FOR WIRE BRUSHING
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.
d. Do not exceed 15,000 RPM when using wire
brushes.
DO NOT WORK WITH MATERIALS

TAKE PROTECTIVE MEASURES
WARNING
!
WHEN DURING WORK DUST CAN
DEVELOP THAT IS HARMFUL TO ONE'S HEALTH,
COMBUSTIBLE OR EXPLOSIVE (SOME DUSTS ARE
CONSIDERED CARCINOGENIC); WEAR A DUST MASK
AND WORK WITH DUST/CHIP EXTRACTION WHEN

ENVIRONMENT
The machine, accessories and packaging should be sorted
for environmental-friendly recycling.
ONLY FOR EC COUNTRIES
Do not dispose of power tools with household
waste!
According the European Guideline 2012/19/EC
for Waste Electrical and Electronic Equipment
and its implementation into national law, power
tools that are no longer usable must be collected
separately and disposed of in an environmentally-
correct manner.
