General power tool safety warnings
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.
The term “power tool” in the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
b) 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.
c) Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling
or unplugging the power tool. Keep cord away from heat,
oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) 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.
f) 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.
PERSONAL SAFETY
a) 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.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) 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.
d) Remove any adjusting key or wrench before turning the power
tool on. A wrench or a key left attached to a rotating part of the
power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in unexpected
1

situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep
your hair, clothing and gloves away from moving parts. Loose
clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction
and collection facilities, ensure these are connected and
properly used. Use of dust collection can reduce dust-related
hazards.
POWERTOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for
your application. The correct power tool will do the job better and
safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and
off. Any power tool that cannot be controlled with the switch is
dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery
pack from the power tool before making any adjustments,
changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the reach of children and do
not allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of
moving parts, breakage of parts and any other condition that
may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier
to control.
g) Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into account the
working conditions and the work to be performed. Use of the
power tool for operations different from those intended could result
in a hazardous situation.
SERVICE
a) Have your power tool serviced by a qualified repair person
using only identical replacement parts. This will ensure that the
safety of the power tool is maintained.
b) If the replacement of the supply cord is necessary, this has to
be done by the manufacturer or his agent in order to avoid a
safety hazard.

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 accessory
may fly away and cause injury beyond immediate area of
operation.
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.
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.
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.
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

Operations for which the power tool was not designed may
create a hazard and cause personal injury.
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.
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.
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, flanges, backing pads or any other
accessory must properly fit the spindle of the power tool.
Accessories 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 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. 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.
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

or other liquid coolants may result in electrocution or shock.
Your hand must hold on the handle when you are working.
Always use the auxiliary handles supplied with the tool. Loss of
control can cause personal injury.
FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS
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.
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.
Never place your hand near the rotating accessory. Accessory
may kickback over your hand.
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.
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.
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
CUTTING-OFF OPERATIONS
SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE
CUTTING-OFF OPERATIONS:
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.
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.
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 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.

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 CUTTING-OFF
OPERATIONS
ADDITIONAL SAFETY WARNINGS SPECIFIC FOR ABRASIVE
CUTTING-OFF OPERATIONS:
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.
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.
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.
Do not restart the cutting operation in the workpiece. 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
workpiece.
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.
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.

GRINDING/CUTTING DISC
Pay attention to the dimensions of the grinding disc. The
mounting hole diameter must fit the inner flange (6) without
play. Do not use reducers or adapters.
When using a diamond cutting disc, take care that the direction-
of-rotation arrow on the diamond cutting disc and the direction of
rotation of the machine (direction-of-rotation arrow on the machine
head) agree.
For mounting, see the Component list illustration page.
Screw on the outer flange (5) and tighten with the two-pin spanner
(9). (See Fig. B)
ADJUSTABLE OUTER FLANGE CLAMPING
The outer flange (5) should be adjusted to suit different disc
thickness. For thinner cutting or diamond discs the raised part of the
outer flange is fitted facing away from the disc (See Fig. C.2). For
thicker grinding discs the raised part of the outer flange is fitted facing
towards the disc to provide improved support for the disc hole
(See Fig. C.1). Always ensure your disc is securely clamped.
ADJUSTING THE PROTECTION GUARD
Before any work on the machine itself, pull the mains plug.
For work with grinding or cutting discs, the protection guard
must be mounted.

ROUGH GRINDING
The best roughing results are achieved when setting the machine
at an angle of 30° to 40°. Move the machine back and forth with
moderate pressure. In this manner, the workpiece will not become
too hot, does not discolour and no grooves are formed.
Warning! Never use a cutting disc for roughing.
CUTTING
Warning! For cutting metal, always work with the wheel
guard for cutting.
When cutting, do not press, tilt or oscillate the machine. Work with
moderate feed, adapted to the material being cut.
Do not reduce the speed of running down cutting discs by applying
sideward pressure.
The direction in which the cutting is performed is important.
The machine must always work in an up-grinding motion. Therefore,
never move the machine in the other direction! Otherwise, the
danger exists of it being pushed uncontrolled out of the cut.
ROTATING THE GEAR CASE
Before any work on the machine itself, pull the mains plug, and
then remove the disc and guard
The gear case can be rotated with respect to the machine housing. In
this manner, the On/Off switch can be brought to an advantageous
handling position for special working situations.
Remove the 4 x screws from the gear case. Carefully rotate the gear
case in your desired direction but do NOT pull the gear case out of
the housing. If the gear case comes out of the housing the motor
carbon brushes will need replacing.
Screw in the screws again and tighten. (See Fig. F)

Working hints for your angle
grinder
If your power tool becomes too hot, run no load for 2-3 minutes to cool
the motor.
Never start your angle grinder with the disc/ accessory in contact with
the workpiece.
Always start at no load to achieve maximum speed then start working.
Do not force the disc to work faster, reducing the Disc’s moving speed
means longer working time.
When grinding, always work with a 30° to 40° angle between disc and
workpiece. Larger angles will cut ridges into the workpiece and affect
the surface finish. Move the angle grinder across and back and forth
over the workpiece.
When using a cutting disc never change the cutting angle otherwise
you will stall the disc and angle grinder motor or break the disc.
When cutting, only cut in the opposite direction to the disc rotation. If
you cut in the same direction as the disc rotation the disc may push
itself out of the cut slot.
When cutting very hard material best results can be achieved with a
diamond disc.
When using a diamond disc it will become very hot. If this happens
you will see a full ring of sparks around the rotating disc. Stop cutting
and allow to cool at no load speed for 2-3 minutes.
Always ensure the workpiece is firmly held or clamped to prevent
movement.
Maintenance
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
Your power tool requires no additional lubrication or maintenance.
There are no user serviceable parts in your power tool. Never use
water or chemical cleaners to clean your power tool. Wipe clean with
a dry cloth. Always store your power tool in a dry place. Keep the
motor ventilation slots clean. Keep all working controls free of dust.
Occasionally you may see sparks through the ventilation slots. This is
normal and will not damage your power tool.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to
avoid a hazard.
Environmental protection
Waste electrical products should not be disposed of with
household waste. Please recycle where facilities exist. Check
with your local authorities or retailer for recycling advice.
