Safety warnings specific for Grinding
and Abrasive Cutting-Off operations
 Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be ade-
quately guarded and are unsafe.
 The grinding surface of the centre depressed
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that pro-
jects through the plane of the guard lip cannot be ade-
quately protected.
 The guard must be securely attached to the
power tool and positioned for maximum
safety, so the least amount of wheel is
exposed towards the operator. The guard helps
to protect operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could ignite
clothing.
 Wheels must be used only for recommended
applications. For example: do not grind with
the side of the cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding; side forces
applied to these wheels may cause them to shatter.
 Always use undamaged wheel flanges that
are of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel thus
reducing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel
flanges.
 Do not use worn down reinforced wheels from
larger power tools. Wheels intended for larger
power tools are not suitable for the higher speed of a
smaller tool and may burst.
Additional safety warnings specific for
abrasive cutting-off operations
 Do not "jam" the cut-off wheel or apply exces-
sive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting or bind-
ing of the wheel in the cut and the possibility of kickback
or wheel breakage.
 Do not position your body in line with and
behind the rotating wheel. When the wheel, at the
point of operation, is moving away from your body, the
possible kickback may propel the spinning wheel and the
power tool directly at you.
 When wheel is binding or when interrupting a
cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the
cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
 Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk
up or kickback if the power tool is restarted in the work-
piece.
 Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. 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.
 Use extra caution when making "plunge cuts"
into existing walls or other blind areas. The pro-
truding wheel may cut gas or water pipes, electrical wir-
ing or objects that can cause kickback.

Additional safety warnings

Wear safety goggles.
 Use appropriate detectors to determine if util-
ity lines are hidden in the work area or call the
local utility company for assistance. Contact with
electric lines can lead to fire and electric shock. Damaging
a gas line can lead to explosion. Penetrating a water line
causes property damage.
 Release the On/Off switch and set it to the off
position when the power supply is inter-
rupted, e.g. when the battery pack is
removed.
 Do not touch grinding and cutting discs before
they have cooled down. The discs can become very
hot while working.
 Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than by
hand.
 Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g.,
against continuous intense sunlight, fire,
water, and moisture. Danger of explosion.
