ABRASIVE CUTTING-OFF OPERATIONS
„ The arbour size of wheels and flanges must properly
fit the spindle of the power tool. Wheels and flanges
with arbour holes that do not match the mounting hard-
ware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
„ Do not use damaged wheels. Before each use, in-
spect the wheels for chips and cracks. If power tool
or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the
wheel, position yourself and bystanders away from
the plane of the rotating wheel and run the power tool
at maximum no load speed for one minute. Damaged
wheels will normally break apart during this test time.
„ Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or res-
pirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
„ Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear per-
sonal protective equipment. Fragments of workpiece or
of a broken wheel may fly away and cause injury beyond
immediate area of operation.
„ Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting acces-
sory contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the operator
an electric shock.
„ Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel may grab
the surface and pull the power tool out of your control.
„ 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.
„ 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.
„ Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
KICKBACK AND RELATED WARNINGS:
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel. Pinching or snagging causes rapid stalling of the
rotating wheel which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the wheel's
rotation at the point of the binding.
SAFETY INSTRUCTIONS FOR
4 — English
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:
„ 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 reac-
tions or kickback forces, if proper precautions are taken.
„ Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
„ Do not position your body in line with the rotating
wheel. Kickback 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, seg-
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
„ Do not "jam" the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and sus-
ceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
„ 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 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.
„ 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.
„ Support panels or any oversized workpiece to mini-
mize 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.
