cut while the wheel is in motion otherwise
kickback may occur. Investigate and take
corrective action to eliminate the cause of
wheel binding.
d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed
under the workpiece near the line of cut and
near the edge of the workpiece on both sides
of the wheel.
f) Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause
kickback.
Special safety instructions
• Check that the maximum speed indicated on
the grinding disc corresponds to the maximum
speed of the machine.
The speed of the machine must not exceed
the value on the grinding disc.
• Make sure that the dimensions of the grinding
disc correspond to the specifications of the
machine.
• Make sure that the grinding disc has been
mounted and fastened properly. Do not use
reducing rings or adapters to make the
grinding disc fit properly.
• Treat and store grinding discs in conformance
with the supplier’s instructions.
• Do not use the machine for grinding
workpieces with a maximum thickness
exceeding the maximum grinding depth of the
grinding disc.
• Do not use grinding discs for deburring.
• When grinding discs have to be mounted on
the thread of the spindle, make sure that the
spindle has sufficient thread. Make sure that
the spindle is sufficiently protected and does
not touch the grinding surface.
• Before use, inspect the grinding disc for any
damage. Do not use grinding discs which are
cracked, ripped or otherwise damaged.
• Before use, let the machine run idle for 30
seconds. Immediately switch off the machine
in case of abnormal vibrations or occurrence
of another defect. Carefully inspect the
machine and grinding disc before switching
the machine on again.
• Make sure that sparks do not put people into
danger or that they contact highly flammable
substances.
• Make sure that the workpiece is sufficiently
supported or clamped. Keep your hands away
from the surface to be cut.
• Always wear safety goggles and hearing
protection. If desired or required also use
another kind of protection like for example an
apron or helmet.
• Ensure that mounted wheels and points are
fitted in accordance with the manufacturer’s
instructions.
• Ensure that blotters are used when they are
provided with the bonded abrasive product
and when they are required.
• If a guard is supplied with the tool never use
the tool without such a guard.
• 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.
• Ensure that ventilation openings are kept
clear when working in dusty conditions. If it
should become nessesary to clear dust, first
disconnect the tool from the mains supply
(use non metallic objects) and avoid
damaging internal parts.
• Though poor conditions of the electrical
mains, shortly voltage drops can appear when
starting the equipment. This can influence
other equipment (eq. blinking of a lamp). If the
mains-impedance Zmax <0.348 Ohm, such
disturbances are not expected. (In case of
need, you may contact your local supply
authority for further information.
Immediately switch off the machine when:
• Excessive sparking of the carbon brushes and
verticiliosis in the collector.
• Interruption of the mains plug, mains lead or
mains lead damage.
• Defect switch
• Smoke or stench of scorched isolation
Electrical safety
When using electric machines always observe the
safety regulations applicable in your country to
reduce the risk of fire, electric shock and personal
injury. Read the following safety instructions and
also the enclosed safety instructions.
