parts. This will ensure that the safety of the power tool
is maintained.
Additional safety instructions for
grinding, sanding, and abrasive
cutting-off operations
a) This power tool is intended to function as a
grinder or cut-off tool. Read all safety warnings,
instructions, illustrations and specications
provided with this power tool.
Failure to follow all instructions listed below may
result in electric shock, r and/or serious injury.
b) Operations such as sanding, wire brushing, or
polishing are not recommended to be performed
with this power tool. Operations for which the power
tool was not designed may create a hazard and cause
personal injury.
c) Do not use accessories which are not
specically designed and recommended by the
tool manufacturer. Just because the accessory can
be attached to your power tool, it does not assure safe
operation.
d) The rated speed of the accessory must be at
least equal to the maximum speed marked on the
power tool. Accessories running faster than their
rated speed can break and y apart
e) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot
be adequately guarded or controlled.
f) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by anges, the arbour hole of the
accessory must t the locating diameter of the
ange. Accessories that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
g) Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive wheels
for chips and cracks, backing pad for cracks, tear or
excess wear, 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 workshop apron
capable of stopping small abrasive or work piece
fragments. The eye protection must be capable of
stopping ying debris generated by various operations
. The dust mask or respirator must be capable of
ltrating 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 y away and
cause injury beyond immediate area of operation.
j) Hold power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring or its
own cord. Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool “live”
and shock the operator.
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 ammable
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.
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 work piece, 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 rm 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 reactions 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
movement at the point of snagging.
d) 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.
e) Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create frequent
kickback and loss of control.
Additional safety instructions for
grinding and abrasive cutting-off
operations
e) Always use undamaged wheel anges that are
of correct size and shape for your selected wheel.
Proper wheel anges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel anges.
f) 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 instructions for
abrasive cutting-off operations
a) Do not “jam” the 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
binding of the wheel in the cut and the possibility of
kickback or wheel breakage.
b) 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 spinning wheel and
the power tool directly at you.
c) 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 corrective action to eliminate the cause of wheel
binding.
d) Do not restart the cutting operation in the work
piece. 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 work
piece.
e) Support panels or any oversized work piece to
minimize the risk of wheel pinching and kickback.
Large work pieces tend to sag under their own weight.
Supports must be placed under the work piece near
the line of cut and near the edge of the work piece on
both sides of the wheel.
f) 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.
Additional safety instructions for
sanding operations
a) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Large sanding paper
extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc or kickback.
The tool is recommended for use with a residual
current device with a rated residual current of
30mA or less
Cutting guard (not supplied) should be tted to
your angel grinder if it is used with an abrasive
cutting wheel
a) Use only wheel types that are recommended for
your power tool and the specic guard designed
for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded
and are unsafe.
b) The grinding surface of centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot be
adequately protected.
c) The guard must be securely attached to the
power tool and positioned for maximum safety, so
the least amount of wheel is exposed towards the
operator. The guard helps to protect operator from
broken wheel fragments and accidental contact with
wheel.
d) 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.
