SAFETY INSTRUCTIONS
Safety Warnings Common for Grinding:
a) This power tool is intended to function as a grinder.
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) This electric tool is not suitable for wire brushing,
cut-off, sanding and polishing. Using the electric tool for
purposes other than those for which it is designed may cause
dangers and injuries.
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 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.
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 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.
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.
WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work patterns.
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.
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.
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 kickback 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 have a tendency to snag the rotating
accessory and cause loss 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.
Safety Warnings Specific for Grinding:
a) 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.
b) Wheels must be used only for recommended
applications.
c) 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.
d) 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.
Appliances used at many different locations including open air
should be connected via a residual current device of 30 mA or
less.
Always wear goggles when using the machine. It is
recommended to wear gloves, sturdy non slipping shoes and
apron.
Always disconnect the plug from the socket before carrying out
any work on the machine.
Only plug-in when machine is switched off.
Keep mains lead clear from working range of the machine.
Always lead the cable away behind you.
After switching off, the machine will not be idle immediately.
(After-running of the work spindle.) Allow the machine to come
to a stop before putting down.
Never reach into the danger area of the plane when it is
running.
Only use tools whose permitted speed is at least as high as the
highest no-load speed of the machine.
Check grinding tools before use. The grinding tool must be
properly mounted and turn freely. Perform a test run for at least
30 seconds without load. Do not use damaged, out of round or
vibrating grinding tools.
When grinding metal, flying sparks are produced. Take care
that no persons are endangered. Because of the danger of fire,
no combustible materials should be located in the vicinity
(spark flight zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust flying
from the workpiece come into contact with you.
The adjusting nut must be tightened before starting to work with
the machine.
Under the effect of extreme electromagnetic interferences from
the outside, temporary variations in the speed of rotation could
arise in particular cases.
Always use and store the grinding disks according to the
manufacturer‘s instructions.
The workpiece must be fixed if it is not heavy enough to be
steady. Never lead the workpiece to the grinding disk with your
hand.
Make sure that the grinding tool is installed in accordance with
the manufacturer‘s instructions.
The size of the grinding tool must be suitable for the grinder.
For dusty operations, the machine‘s ventilation slits must be
kept clear. If necessary, switch off the power to the machine
and remove the dust. Use a non-metallic object for this, taking
care not to damage any of the inner parts.
SPECIFIED CONDITIONS OF USE
Straight grinders are suited for grinding metal, plastic, or similar
