GENERAL SAFETY INSTRUCTIONS

WARNING! Read all safety warnings designated by the symbol and all instructions.

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.

Keep all warnings and all instructions to be able to refer to them later on.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool

1 Safety of the work area

a) Keep the work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate electric tools in explosive atmospheres, for example in the presence of

flammable liquids, gases or dust. Electric tools create sparks that can ignite the dust or fumes.

c) Keep children and bystanders away while operating the tool. Distractions can cause you to lose

control of the tool.

2 Electrical safety

a) The electric tool plugs must match the outlet. Never modify the plug in any way. Do not use

adapters with earthed (grounded) tools. Unmodified plugs and matching outlets will reduce the risk

of electric shock.

b) Avoid any body contact with earthed or grounded surfaces such as pipes, radiators, cookers

and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose tools to rain or wet conditions. Water entering a tool will increase the risk of

electrical shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the tool. Keep

the cord away from heat, lubricants, edges and moving parts. Damaged or entangled cords

increase the risk of electric shock.

e) When using a tool outside, use an extension cable suitable for outside use. Use of a cord

suitable for outside use reduces the risk of electric shock.

f) If use of a tool in a humid location is unavoidable, use a supply protected by a residual current

differential device (RCD). The use of an RCD reduces the risk of electri c sho ck.

3 Personal safety

a) Stay alert, watch what you are doing and use common sense when operating the tool. Do not

use the tool when you are tired or under the influence of drugs, alcohol or medication. One

moment of carelessness while using a tool can result in serious pe rsonal injury.

b) Use safety equipment. Always wear eye protection. Safety equipment such as dust masks,

non-slip safety shoes, a hard hat and hearing protection used for appropriate conditions will reduce
personal injuries.

c) Avoid unintentional starting. Make sure that the switch is in the off position before plugging

the tool into the mains and/or fitting the batteries, picking it up or carrying it. Carrying tools with

your finger on the switch or plugging in tools with the switch in the on position is a cause of accident s.

d) Remove any adjustment key before operating the tool. A key left attached to a rotating part of the

tool can result in personal injury.

e) Do not overreach. Keep a proper position and balance at all times. This enables better control of

the tool in unexpected situations.

f) Dress in a suitable manner. Do not wear loose clothing or jewellery. Keep hair, clothing and

gloves away from moving parts. Loose clothing, jewellery or long hair can be caught in moving

parts.

g) If devices are provided for the connection of dust extraction and collection equipment, make

sure that they are connected and used correctly. Using dust collectors can reduce the dust-related

risks.

4 Use and maintenance of the tool

a) Do not force the tool. Use the correct tool for your application. The correct tool will do the work

better and safer in the conditions for which it was manufactured.

b) Do not use the tool if the switch does not make it possible to change from the operating

condition to stop and vice versa. Any tool which cannot be controlled by the switch is dangerous

and should be repaired.

c) Disconnect the power cord before any adjustment, changing an accessory or before storing

the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

d) Keep idle tools out of the reach of children and do not allow persons unfamiliar with the tool or

these instructions to operate it. Tools are dangerous in the hands of untrained users.

e) Maintain the tool. Check that there is no misalignment or obstruction of the moving parts,

broken parts or any other condition that could affect the operation of the tool. In the event of
damage, have the tool repaired before using it. Many accidents are due to b adly maintained tools.

f) Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less

likely to bind and are easier to control.

g) Use the tool, accessories and blades etc., in accordance with these instructions, while taking

into account the work conditions and the work to be done. The use of the tool for operations other

than those intended could result in dangerous situations.

5) Service

a) Have your power tool serviced by a qualified repair person using only identicalreplacement

parts. This will ensure that the safety of the power tool is maintained.

SPECIAL SAFETY INSTRUCTIONS

Safety Warnings Common for Grinding or 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 specifications provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious injury.
b) Operations such as sanding, wire brushing, 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 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.
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 fly 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) 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.
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 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.

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 fly away and cause
injury beyond immediate area of operation.
J) 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.
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 flammable 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.

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, dep ending 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 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 kick back 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 h ave a tendency to sna g the rotating accesso ry and cause l oss

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 cutting-off operations
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations:

810W 115mm

A

a) Use only wheel types that are recommended for your power tool and the specific gua rd designed for
the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and
are unsafe.
b) 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.
c) 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.
d) Always use undamaged wheel flanges that are of correct size and shap e 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.
e) 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:

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 kick back 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 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.
e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.

Large work pieces tend to sag under their own weight. Support s must be pla ced unde r the wo rkpiece n ear t he
line of cut and near the edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a “pocket cut” into existing walls or o ther blind area s. The protrudi ng
wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

WARNING

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:

- lead from lead-based paints,

- crystalline silica from bricks and cement and other masonry prod ucts, and

- arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter out microscopic particles.

NOISE INFORMATION

Wear hearing protection!

Measured sound values determined according to EN 60745.
The noise figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a
correlation between the emission and exposure levels, this cannot be used reliably to determine wh ether or
not further precautions are required. Factors that influence the actual level of exposure of work-force include
the characteristics of the work room, the other sources of noise, etc. i.e. the number of machines and other
adjacent processes, and the length of time for which an operator is exposed to the noise. Also the permissible
exposure level can vary from country . This inform ation, however, will enable the user of the machine to make a
better evaluation of the hazard and risk.

VIBRATION INFORMATION
The European Physical Agents (Vibration) Directive has been brought in to help reduce hand arm vibration
syndrome injuries to power tool users. The directive requires power tool manufacturers and suppliers to
provide indicative vibration test results to enable users to make informed decisions as to the period of time a
power tool can be used safely on a daily basis and the choice of tool.
Further advice can be found at www . hse.gov.uk

Vibration total values (triax vector sum) determin ed according to EN 60745:

Vibration emission value a
Uncertainty K = 1.5 m/s

The declared vibration emission value should be used as a minimum level and should be used with the current
guidance on vibration.

The declared vibration emission been measured in a ccordance wit h a st andardised test st ated above and may
be used to compare one tool with another tool.The declared vibration emission value may also be used in a
preliminary assessment of exposure.

WARNING!

The vibration emission value during actual use of the power tool can differ from the declared value depending
on the ways in which the tool is used dependent on the following examples and other variations on how the
tool is used:
How the tool is being used and the materials being sanding or cutting.
The tool being in good condition and well maintained
The use the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles.
And the tool is being used as intended by its design and these instructions.

While working with this power tool, hand/arm vibrations occur. Adopt the correct working practices in order to
reduce the exposure to vibration.

This tool may cause hand-arm vibration syndrome if its use is not adequately managed.

WARNING!

Identify safety measures to protect the operator that are based on an estimation of exposure in the actual
conditions of use (taking account of all part s of the operating cycle su ch as the times when the tool is swit ched
off and when it is running idle in addition to the trigger time).
