GRINDING AND ABRASIVE CUT-OFF OPERATIONS
•
Use only types of grinding wheel that are compatible with your electric tool and the specific
protection of the grinding wheel of your choice.
The grinding wheels which were not conceived for
your power tool cannot be adequately protected and are not safe.
•
The protection must be firmly fixed to the electric tool and safely positioned so that the operator
is exposed to the grinding wheel as little as possible.
The protection allows to protect the operator
from fragments of broken grinding wheel and from an accidental contact with the wheel.
•
The grinding wheels must only be used for the recommended applications. For example: do
not grind with the side of the grinding wheel to cut something.
Cutting grindstones are destined to
peripheral grinding; by pushing on the side of these wheels, they can break.
•
Always use flanges which are not damaged and whose shape and size are correct for the
grinding wheel of your choice.
Adequate flanges for grinding wheels support them reducing the risk of
breaking the wheel. Flanges for cutting wheels can be different from flanges for grinding wheels.
•
Do not use used grinding wheels of bigger electrical tools.
Grinding wheels destined to bigger
electrical tools are not adequate because of the higher speed of smaller tools: the grinding wheel can
explode.
CUTTING OPERATIONS
•
Do not ‘block’ the cutting wheel or push excessively. Do not try to make the cut excessively
deep.
By pushing on the wheel, its load increases as well as the chances of twisting or bending the
wheel while cutting and the chances of recoil or breaking the wheel.
•
Do not stand next to the rotating wheel or behind it.
While working, the grinding wheel separates
from the body and the possible recoil can push it and the electric tool towards you.
•
When the grinding wheel bends or when the cutting operation is interrupted for any reason,
remove the power plug of the electric tool and keep it still until the wheel stops. Do not try to
remove the cutting wheel from the cut while it is moving or a recoil can happen.
You have to
identify the reasons why the wheel bent and take appropriate measures so that it doesn’t happen again.
•
Do not resume the cutting operation of the working item. Let the grinding wheel reach its
maximum speed and carefully insert it again in the cut.
If the electrical tool is restarted while inside
the working item, the grinding wheel can stop, go back up or have a recoil.
•
Arrange a stand for the panels or any other working piece with big size in order to minimize the
risk that the wheel gets stuck or recoils.
Big working pieces tend to bend under their own weight.
Stands must be put under the working piece near the cutting line and near their edge on both sides of
the wheel.
•
Be careful especially when doing a ‘groove cut’ on existing walls or other areas that are not
visible.
The jutting out grinding wheel can cut water or gas pipes, electrical wires or objects, events
which can cause recoil.
NOISE AND VIBRATIONS
The level of noise and vibrations shown on the attached sheet are average values for the use of the power
tool. The use of different attachments, different materials, different processes such as cutting or wire brushing
and the lack of tool maintenance all have significant influence on noise and vibration. Therefore adopt all
the preventative measures necessary to eliminate any possible damage due to loud noises and strain from
vibrations; wear ear phones, anti-vibration gloves, take breaks while working and ensure the power tool and
its accessories are kept efficient at all times.

USING A METAL BRUSH ATTACHMENT (NOT INCLUDED)
•
When using the brush, even during normal operation, metal bristles may be emitted. Do not
apply excessive weight on the brush.
The wire bristles can easily penetrate light clothing and/or skin.
If it is recommended to use protective equipment for wire brushing, do not allow this to interfere
with the metal wire disc or the wire brush in any way.
The metal wire disc or the brush may expand
in diameter due to workload and centrifugal forces.
