Read all safety warnings, instructions and
specifications provided with this power
tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious
injury. Save all warnings and instructions for
future reference.
WARNING!
The term “power tool” in the warnings refers to
your mains operated (corded) power tool or battery
operated (cordless) power tool.
1. Work area safety
m Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
m Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust or
fumes.
m Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2. Electrical safety
m Power tool plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric
shock.
m Avoid body contact with earthed or
grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body
is earthed or grounded.
m Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
m Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep the cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of
electric shock.
m When operating a power tool outdoors,
use an extension cord suitable for
outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock.
m If operating a power tool in a damp
location is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3. Personal safety
m Stay alert, watch what you are doing
and use common sense when operating
a power tool. Do not use a power tool
while you are tired or under the influence
of drugs, alcohol or medication. A moment
of inattention while operating power tools may
result in serious personal injury.
m Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-skid safety
shoes, hard hat or hearing protection used for
appropriate conditions will reduce personal
injuries.
m Prevent unintentional starting. Ensure
the switch is in the off position before
connecting to power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your finger on
the switch or energising power tools that have
the switch on invites accidents.

off 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.
m Do not use accessories which
are not specifically designed
and recommended by the tool
manufacturer. Just because the accessory
can be attached to your power tool, it does
not assure safe operation.
m 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.
m 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.
m Threaded mounting of accessories
must match the grinder spindle
thread. For accessories mounted
by flanges, the arbour hole of the
accessory must fit the locating
diameter of the flange. 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.
List only those operations that were not
included in the first warning. If all listed oper-
ations are recommended, then this warning
may be omitted, but all subsequent warnings
are to be given without exclusion.
NOTE

21-AG125
Instruction & User Manual
m 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.
m 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 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.
m 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.
m Hold the power tool by insulated
gripping surfaces only, when
performing an operation where
the cutting accessory may contact
hidden wiring or its own cords. Cutting
accessory contacting a “live” wire may make
exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
m 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.
m 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.
m 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.
m Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
The above warning may be omitted if pol-
ishing or sanding are the only recommended
operations.
NOTE

821-AG125
Instruction & User Manual
m 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 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.
m 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
reactions or kickback forces, if proper
precautions are taken.
m Never place your hand near the
rotating accessory. Accessory may
kickback over your hand.
m 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.
m 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.
m Do not attach a saw chain
woodcarving blade or toothed saw
blade. Such blades create frequent kickback
and loss of control.
Safety Warnings Specific for
Grinding and Abrasive Cutting-
Off Operations
m Use only wheel types that are
recommended for your power tool
and the specific guard designed for
the selected wheel. Wheels for which
the power tool was not designed cannot be
adequately guarded and are unsafe.
m 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.
m 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 the broken wheel fragments,
accidental contact with wheel and sparks
that could ignite clothing.

9
21-AG125
Instruction & User Manual
m 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.
m Always use undamaged wheel flanges
that are of correct size and shape
for your selected wheel. Proper wheel
flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges
for cut-off wheels may be different from
grinding wheel flanges.
m 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
Specific for Abrasive Cutting-Off
Operations
m 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.
m 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.
m 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.
m 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.
m 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.
m 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.
The above warning may be omitted for
grinders or cut-off grinders with a rated
capacity of less than 55mm.
NOTE

10 21-AG125
Instruction & User Manual
Safety Warnings Specific for
Sanding Operations
m Do not use excessively oversized
sanding disc paper. Follow
manufacturers recommendations,
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.
Safety Warnings Specific for
Polishing Operations
m Do not allow any loose portion of the
polishing bonnet or its attachment
strings to spin freely. Tuck away or
trim any loose attachment strings.
Loose and spinning attachment strings
can entangle your fingers or snag on the
workpiece.
Safety Warnings Specific for Wire
Brushing Operations
m 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.
m 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.
The electric motor has been designed
for operation on a 220-240V AC 50/60
Hz power supply. 220-240V AC means
your tool will operate on alternating
current at a voltage range from 220-
240V. As little as 10% lower operating
voltage (or incorrect mains HZ fre-
quency) can cause loss of power and
overheating. All JCB tools are factory
tested. If this tool does not operate
check the power supply. Make sure your
power supply agrees with the voltage
specified on the product rating label.
m Replacement of the supply cord. If the
supply cord is damaged, it must be replaced
by the manufacturer or an authorised JCB
Service Centre in order to avoid a hazard.
We recommend the use of a
residual current device (R.C.D.)
with a residual current rating of
30mA or less.
ELECTRICAL SAFETY
This electric tool generates an
electromagnetic field during operation.
This field may under some circumstances
interfere with active or passive medical
implants. To reduce the risk of serious or
fatal injury, we recommend persons with
medical implants consult their physician
and the medical implant manufacture
prior to operating this power tool.
