Cordless grinder safety warnings
Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-O󰀨 Operations:
1.
This power tool is intended to function as a grinder,
sander, wire brush or cut-o󰀨 tool. Read all safety
warnings, instructions, illustrations and specica-
tions provided with this power tool. Failure to follow
all instructions listed below may result in electric shock,
re and/or serious injury.
2. Operations such as 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.
3. Do not use accessories which are not specically
designed and recommended by the tool manufac-
turer. Just because the accessory can be attached to
your power tool, it does not assure safe operation.
4. 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.
5. 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.
6.
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.
7. 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 maxi-
mum no-load speed for one minute. Damaged acces-
sories will normally break apart during this test time.
8. 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 workpiece
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 expo-
sure to high intensity noise may cause hearing loss.
9. 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 accessory may y away and cause injury
beyond immediate area of operation.
10. 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.

11 ENGLISH
11. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
12.
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.
13. 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.
14. Do not operate the power tool near ammable
materials. Sparks could ignite these materials.
15. 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 acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled 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 power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
1. 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 kick-
back forces, if proper precautions are taken.
2. Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
3. 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.
4. 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.
5. Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specic for Grinding and Abrasive
Cutting-O󰀨 Operations:
1. Use only wheel types that are recommended
for your power tool and the specic guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
2.
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.
3. 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 the operator from broken
wheel fragments, accidental contact with wheel and
sparks that could ignite clothing.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-o󰀨 wheel. Abrasive cut-o󰀨 wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
5. 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-o󰀨 wheels may be di󰀨erent from
grinding wheel anges.
6. 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 Warnings Specic for Abrasive
Cutting-O󰀨 Operations:
1. Do not “jam“ the cut-o󰀨 wheel or apply exces-
sive 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 possibil-
ity of kickback or wheel breakage.
2. 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 spin-
ning wheel and the power tool directly at you.
3. When wheel is binding or when interrupting
a cut for any reason, switch o󰀨 the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the cut-o󰀨 wheel from the
cut while the wheel is in motion otherwise
kickback may occur. Investigate and take correc-
tive action to eliminate the cause of wheel binding.
4. 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.
5. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. 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.
6. Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
Safety Warnings Specic for Sanding Operations:
1. Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper. Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.

12 ENGLISH
Safety Warnings Specic for Wire Brushing
Operations:
1. 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.
2. If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work load
and centrifugal forces.
Additional Safety Warnings:
1.
When using depressed centre grinding wheels, be
sure to use only berglass-reinforced wheels.
2. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product
may result in serious personal injury.
3. Be careful not to damage the spindle, the
ange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
4. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
5. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
6. Use the specied surface of the wheel to per-
form the grinding.
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
9. Do not touch accessories immediately after
operation; it may be extremely hot and could
burn your skin.
10. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
11. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
12. Use only anges specied for this tool.
13. For tools intended to be tted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
14. Check that the workpiece is properly
supported.
15. Pay attention that the wheel continues to
rotate after the tool is switched o󰀨.
16. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
17. Do not use the tool on any materials contain-
ing asbestos.
18. When use cut-o󰀨 wheel, always work with
the dust collecting wheel guard required by
domestic regulation.
19. Cutting discs must not be subjected to any
lateral pressure.
20. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
21. Make sure there are no electrical cables, water
pipes, gas pipes etc. that could cause a hazard
if damaged by use of the tool.

OPERATION
WARNING: It should never be necessary to
force the tool. The weight of the tool applies ade-
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING: ALWAYS replace wheel if tool is
dropped while grinding.
WARNING: NEVER bang or hit grinding disc
or wheel onto work.
WARNING: Avoid bouncing and snagging the
wheel, especially when working corners, sharp edges
etc. This can cause loss of control and kickback.
WARNING: NEVER use tool with wood cutting
blades and other saw blades. Such blades when
used on a grinder frequently kick and cause loss of
control leading to personal injury.
CAUTION: Never switch on the tool when it
is in contact with the workpiece, it may cause an
injury to operator.
CAUTION: Always wear safety goggles or a
face shield during operation.
CAUTION: After operation, always switch o󰀨
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION: ALWAYS hold the tool rmly with
one hand on housing and the other on the side
grip (handle).
Grinding and sanding operation
► Fig.25
Turn the tool on and then apply the wheel or disc to the
workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded o󰀨 by use, the wheel may be worked in both
forward and backward direction.
Operation with abrasive cut-o󰀨 /
diamond wheel
Optional accessory
WARNING: 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, wheel breakage and overheating of the
motor may occur.
WARNING: Do not start the cutting operation
in the workpiece. Let the wheel reach full speed
and carefully enter into the cut moving the tool
forward over the workpiece surface. The wheel
may bind, walk up or kickback if the power tool is
started in the workpiece.
WARNING: During cutting operations, never
change the angle of the wheel. Placing side pres-
sure on the cut-o󰀨 wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING: A diamond wheel shall be oper-
ated perpendicular to the material being cut.
