GEA010-1
WARNING Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future
reference.
1.
5.
The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. Position yourself and bystanders away
from the plane of the rotating wheel. The guard
helps to protect operator from broken wheel
fragments and accidental contact with wheel.
7.
8.
Use only diamond cut-off wheels for your power
tool. Just because an accessory can be attached to
your power tool, it does not assure safe operation.
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 fly apart.
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.
Always use undamaged wheel flanges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
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.
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 hardware 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,
inspect 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.

17.
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 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.
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 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 or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the
operator an electric shock.
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 wheel.
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
materials. Sparks could ignite these materials.
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. 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.
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. Always use auxiliary
handle, if provided, for maximum control
over kickback or torque reaction during startup. 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 line with the
rotating wheel. 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, segmented diamond wheel with a
peripheral gap greater than 10 mm or toothed
saw blade. Such blades create frequent
kickback and loss of control.
f) 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 susceptibility to
twisting or binding of the wheel in the cut and the
possibility of kickback or wheel breakage.
g) 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.
h) 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.
i) 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.
j) 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.
18. Before using a segmented diamond wheel, make
sure that the diamond wheel has the peripheral
gap between segments of 10 mm or less, only
with a negative rake angle.
7
Additional Safety Warnings:
19. Never attempt to cut with the tool held upside
down in a vise. This can lead to serious
accidents, because it is extremely dangerous.
20. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
21. Store
wheels
as
per
manufacturer
recommendations. Improper storage may
damage the wheels.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this
instruction manual may cause serious personal
injury.
