personal protective equipment such as dust
mask, gloves, helmet and apron should be
worn.
Always be sure that the tool is switched off
and unplugged before carrying out any work
on the tool.
Keep guards in place.
Use only wheels with correct size and wheels
having a maximum operating speed at least as
high as the highest No Load Speed marked on
the tool's nameplate. When using depressed
center wheels, be sure to use only
fiberglass-reinforced wheels.
Check the wheel carefully for cracks or
damage before operation. Replace cracked or
damaged wheel immediately.
Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
Use only flanges specified for this tool.
Do not damage the spindle, the flange
(especially the installing surface) or the lock
nut. Damage to these parts could result in
wheel breakage.
For tools intended to be fitted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
Before using the tool on an actual workpiece,
test run the tool at the highest no load speed
for at least 30 seconds in a safe position. Stop
immediately if there is any vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel. Check the tool to
determine the cause.
Check that the workpiece is properly
supported.
Hold the tool firmly.
Keep hands away from rotating parts.
Make sure the wheel is not contacting the
workpiece before the switch is turned on.
Use the specified surface of the wheel to
perform the grinding.
Do not use cutting off wheel for side grinding.

Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
Position the tool so that the power cord
always stays behind the machine during
operation.
If working place is extremely hot and humid, or
badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure
operator safety.
Do not use the tool on any materials
containing asbestos.
Do not use water or grinding lubricant.
Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first
disconnect the tool from the mains supply
( use non metallic objects ) and avoid
damaging internal parts.
When use cut-off wheel, always work with the
dust collecting wheel guard required by
domestic regulation.
Cutting discs must not be subjected to any
lateral pressure.
