4.11 Additional safety instructions
- If applicable, observe any particular health and
safety or accident prevention regulations
governing the use of compressors and
compressed air tools.
- Ensure that the maximum supply pressure speci-
fied in the Technical Specifications is not
exceeded.
- Do not overload the tool – use it only within the
performance range for which it was designed (see
"Technical Specifications").
- Use non-hazardous lubricants. Ensure the work-
place is adequately ventilated. If there is a large
amount of discharge: check the air tool and have
it repaired if necessary.
- Do not operate the tool unless you are completely
focused. You must be alert, pay attention to what
you are doing and proceed cautiously when
working with an air tool. Never use a tool when you
are tired or under the influence of drugs, alcohol or
medication. Just one moment's carelessness
when using the tool can cause serious injury.
- Make sure your workplace is clean and well lit.
Untidy or poorly lit workplaces can cause acci-
dents.
- Keep air tools away from children.
- Do not store the tool outdoors or in damp condi-
tions without protection.
- Protect the air tool, especially the compressed air
connection and the control elements from dust
and dirt.
4.12 General safety instructions for grinding
and abrasive cutting:
Use
a) This air tool is intended for use as a grinder
and cut-off tool. Refer to all safety warnings,
instructions, illustrations and specifications
provided with this device. Failure to follow all the
instructions may result in electric shock, fire and/or
serious injury.
b) This air tool is not suitable for sanding, wire
brushing and polishing. Using the air tool for
tasks for which it was not designed may create a
hazard and cause personal injury.
c) Do not use accessories that are not specifi-
cally designed and recommended by the tool
manufacturer for this air tool. Just because an
accessory can be attached to your air tool does not
mean safe operation is guaranteed.
d) The rated speed of the mounted tool must at
least equal the maximum speed marked on the
air tool. Accessories running faster than their rated
speed can break and fly apart.
e) The outside diameter and the thickness of
the mounted tool must correspond to the spec-
ified dimensions of your air tool. Incorrectly
sized mounting tools cannot be adequately
protected or controlled.
f) The arbour size of grinding wheels, flanges or
any other accessory must properly fit the
spindle of your air tool. Mounted tools with arbour
holes that do not correspond to the spindle of the air
tool will rotate unevenly, vibrate excessively and
may cause loss of control.
g) Do not use a damaged mounted tool. Before
each use, inspect mounting tools such as
grinding wheels for chips and cracks, backing
pad for cracks, tear or excess wear, wire brush
for loose or cracked wires. If the air tool or
mounted tool is dropped, inspect it for damage
or install an undamaged mounted tool. After
inspecting and installing a mounted tool, posi-
tion yourself and bystanders away from the
plane of the rotating mounted tool and run the
device at maximum no-load speed for one
minute. Damaged mounted tools will normally
break apart during this test time.
h) Wear personal protective equipment.
Depending on the application, use a face
shield, safety goggles or safety glasses. As
appropriate, wear a dust mask, hearing protec-
tors, gloves and workshop apron capable of
stopping small abrasive or workpiece frag-
ments. The eye protection must be capable of stop-
ping flying debris generated by various operations.
The dust mask or respirator must be capable of
filtering particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
i) Keep bystanders a safe distance away from
your work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of a workpiece or broken mounted tools
may fly into the air and cause injury beyond the
immediate area of operation.
j) When carrying out tasks that involve a risk of
the mounted tool contacting hidden wiring,
make sure you hold the device on the insulated
gripping surfaces only. A mounted tool that
comes in contact with a "live" wire may render
exposed metal parts of the device "live" and give the
operator an electric shock.
I) Never lay the air tool down until the mounted
tool has come to a complete stop. The spinning
mounted tool may catch the surface and pull the air
tool out of your control.
m) Do not run the air tool while carrying it at
your side. Accidental contact with the spinning
mounted tool could snag your clothing, pulling the
mounted tool into your body.
o) Do not operate the air tool near flammable
materials. Sparks could ignite these materials.
p) Do not use mounted tools that require liquid
coolants.
4.13 Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating grinding wheel, brush or any other
mounted tool. Pinching or snagging causes the
rotating mounted tool to stop abruptly. This in turn
accelerates the uncontrolled air tool against the
direction of rotation of the mounted tool at the point
of jamming.
For example, if a grinding wheel is snagged or
pinched by the workpiece, the edge of the wheel
penetrating the workpiece may get caught, causing
the grinding wheel to break away or result in kick-
back. The wheel may then be propelled towards or
