wire brush for loose or cracked
wires. If power tool or accessory
is dropped, inspect for damage or
install an undamaged accessory.
After inspecting and installing an
accessory, position yourself and
bystanders away from the plane of
the rotating accessory and run the
power tool at maximum no-load
speed for one minute. Damaged
accessories will normally break apart
during this test time.
h) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety
glasses. As appropriate, wear dust
mask, hearing protectors, gloves
and work shop apron capable of
stopping small abrasive or workpiece
fragments. The eye protection must
be capable of stopping flying debris
generated by various operations. The
dust mask or respirator must be capable
of filtrating particles generated by your
operation. Prolonged exposure to high
intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away
from work area. Anyone entering
the work area must wear personal
protective equipment. Fragments of
workpiece or of a broken accessory
may fly away and cause injury beyond
immediate area of operation.
j) Hold the power tool by insulated
gripping surfaces only, when
performing an operation where the
cutting tool may contact hidden
wiring. Contact with a "live" wire will
also make exposed metal parts of the
power tool "live" and could give the
operator an electric shock.
k) 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.
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool
near flammable materials. Sparks
could ignite these materials.
p) Do not use accessories that require
liquid coolants. Using water or
other liquid coolants may result in
electrocution or shock.
q) Do not use Type 11 (flaring cup)
wheels on this tool. Using inappropriate
accessories can result in injury.
r) Always use side handle. Tighten
the handle securely. The side handle
should always be used to maintain
control of the tool at all times.
s) When starting the tool with a new
or replacement wheel, or a new or
replacement wire brush installed,
hold the tool in a well protected area
and let it run for one minute. If the
wheel has an undetected crack or flaw,
it should burst in less than one minute.
If the wire brush has loose wires, they
will be detected. Never start the tool
with a person in line with the wheel.
This includes the operator.
t) To prevent the spindle end from
contacting the bottom of the
hole of the abrasive product, use
accessories that have a threaded
hole depth of at least 21mm. Failure to
use an accessory with the appropriate
thread depth could result in damage to
the abrasive product and injury to the
operator or persons in the area.
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 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
direction of the wheel's 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 wheel's
