Milwaukee CHS 355 Manual Original página 14

Never perform any operation "freehand". Always secure the
workpiece to be cut in the vice. Refer to specifi cations 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 fl uctuations and may aff ect
other electrical products in the same power line. Connect
the product to a power supply with an impedance equal to
0.233 Ω to minimize voltage fl uctuations. Contact your
electric power supplier for further clarifi cation.
It is recommended that the tool always be supplied via a
residual current device having a rated residual current of
30mA or less.
Milwaukee recommends that you use Metal Cutting Wheel
41A24RBF80 as a replacement whenever you need a new
wheel.
SAFETY WARNINGS FOR FITTING AN ABRASIVE
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
fl ange to engage with the fl ats 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 injury.
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 fi tted
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 identifi ed on the tool while
installing and changing abrasive wheel.
Do not tighten abrasive wheel excessively, since this can
cause cracks.
The cut-off machine 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 easily.
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
26 ENGLISH
3. Abrasive type, grain size, grade or hardness, type of
bond and use of reinforcement e.g. 41A24RBF80.
41 -> abrasive type, fl at 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
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
RESIDUAL RISK
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
• Stability. Ensure the tool is stable, if necessary secure it.
• Inhalation of dust. Wear a mask if necessary.
• Sparks and hot metal particles, these can cause fi re, skin
burns. Wear protective equipment during using.
• Eye injury from metal particles. Wear eye protection when
working.
• Hearing injury – restrict exposure and wear appropriate
hearing protection.
TRANSPORTATION AND STORAGE
The handle must be always secured by the safety knob
when transporting the cut-off machine.
Only transport the cut-off machine on a trolley.
Store the cut-off machine in a dry place and with secured
Head.
