Residual Risks - AEG SMT355-1 Original Instructions Manual

Metal chopsaw


between the wheel and the machine base support. Damage may result
to the wheel if it strikes the machine base support during operation.
Do not attempt to cut wood or masonry with the cut off saw. Never cut
magnesium or magnesium alloy with the machine.
Do not tighten wheel excessively, since this can cause cracks.
Always ease the abrasive wheel against the workpiece when starting
to cut. A harsh impact can break the wheel.
Never cut more than one workpiece at a time. Do not stack more than
one workpiece on the machine base at a time.
To minimise risk of tipping the machine, always support long
Cutting steel will cause sparks. Do not operate in the presence of
combustible or flammable materials.
Never leave tool running unattended. Do not leave tool until it comes
to a complete stop.
Always release the power switch and allow the wheel to stop rotating
before raising it out of the workpiece.
Keep hands away from cutting area. Keep hands away from wheel.
Do not reach underneath work or around or under the wheel while
the wheel is rotating. Do not attempt to remove cut material while
wheel is moving.
Never stand or have any part of your body in line with the path of
the wheel.
Never stand on the tool. Serious injury could occur if the tool is tipped
or if the wheel is unintentionally contacted.
Never perform any operation "freehand". Always secure the workpiece
to be cut in the vice. Refer to specifications table for safe minimum
size of workpiece. Always ensure you grip at least 80 mm in the vice
jaws to ensure security while grinding.
Never hand hold a workpiece; it will become very hot while being cut.
A power spike causes voltage fluctuations and may affect other
electrical products in the same power line. Connect the product to
a power supply with an impedance equal to 0.233
voltage fluctuations. Contact your electric power supplier for further
It is recommended that the tool always be supplied via a residual
current device having a rated residual current of 30mA or less.
AEG recommends that you use Metal Cutting Wheel 089210129800
as a replacement whenever you need a new wheel.
To reduce the risk of injury, user must read and comply with
instructions, warnings and operator's manual before starting to use
the abrasive wheel. Failure to heed these warnings can result in wheel
breakage and serious personal injury. Save these instructions.
The use of any wheel other than the one recommended in the
machine instruction manual may present a risk of personal injury. Use
only abrasive wheels which have marked speed equal or greater to
that marked on the machine.
Never use abrasive wheel that is too thick to allow outer flange to
engage with the flats on the spindle. Larger wheels will come in
contact with the wheel guards, while thicker wheels will prevent the
bolt from securing the wheel on the spindle. Either of these situations
could result in a serious accident and can cause serious personal
This abrasive wheel is for ferrous metal cutting only. Do not attempt
to cut wood or masonry with it. Never cut magnesium or magnesium
alloy with it.
This abrasive wheel is only suitable for dry cutting, and should be used
before the date of expiry (marking on arbour hole e.g., V07/2019).
Do not use damaged abrasive wheels. Do not use wheels that are
chipped, cracked or otherwise defective.
Ensure that the abrasive cutting-off wheel is correctly fitted and
tightened before use.
The direction of rotation of the abrasive wheel is indicated on the tool.
Make sure the direction mark on wheel is consistent with the direction
identified on the tool while installing and changing abrasive wheel.
Do not tighten abrasive wheel excessively, since this can cause cracks.
The saw should never be connected to power supply when you are
installing or removing abrasive wheels.
Store your spare abrasive wheels carefully; they can be damaged
Information available on the abrasive wheel label
The information on the wheel label is IMPORTANT. Read and check it
carefully to ensure you are selecting the correct type of wheel.
1. Manufacturer, supplier, importer or trade mark
2. Nominal dimensions of abrasive wheel, in particular the diameter
of the bore
3. Abrasive type, grain size, grade or hardness, type of bond and use
of reinforcement e.g.
41--- abrasive type, flat cutting-off wheel
A --- abrasive material: brown corundum
24 --- grain size
R --- grade or hardness
BF --- type of bond
80 --- maximum operating speed m/s
4. Maximum operation speed in metres per second
to minimize
5. Maximum permissible speed of rotation in 1/min
6. For declaration of conformity, the abrasive products shall be
marked with EN 12413
7. Restriction of use and safety warning symbols.
8. Traceability code, eg. A production/batch number, expiry date or
series number


Even when the product is used as prescribed, it is still impossible
to completely eliminate certain residual risk factors. The following
hazards may arise and the operator should pay special attention to
avoid the following:
Risk of contact with uncovered parts of the rotating sawblade
Kick-back of workpieces or parts of workpieces due to improper
adjustment or handling
Catapulting of faulty carbide tips from the saw blade
Damage to the respiratory system
NOTE: Wear respiratory protection masks containing filters
appropriate to the materials being worked. Ensure adequate
workplace ventilation. Do not eat, drink or smoke in the work area.
Damage to hearing if effective hearing protection is not worn.
