cutter or tungsten carbide cutter grabs, it may
jump from the groove and you could lose con-
trol of the tool.
Safety warnings specifi c for grinding and
abrasive cutting-off operations:
a) Use only wheel types that are recommended
for your power tool and only for recommen-
ded applications. For example: do not grind
with the side of a cut-off wheel. Abrasive cut-
off wheels are intended for peripheral grinding,
side forces applied to these wheels may cause
them to shatter.
b) For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an un-
relieved shoulder flange that are of correct
size and length. Proper mandrels will reduce
the possibility of breakage.
c) Do not "jam" a cut-off wheel or apply ex-
cessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the
wheel increases the loading and susceptibili-
ty to twisting or snagging of the wheel in the
cut and the possibility of kickback or wheel
breakage.
d) Do not position your hand in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from
your hand, the possible kickback may propel
the spinning wheel and the power tool directly
at you.
e) When wheel is pinched, snagged 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 com-
plete 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 elimi-
nate the cause of wheel pinching or snagging.
f) 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 workpiece.
g) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag un-
der 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.

h) Use extra caution when making a "pocket
cut" into existing walls or other blind are-
as. The protruding wheel may cut gas or wa-
ter pipes, electrical wiring or objects that can
cause kickback.
Safety warnings specifi c for wire brushing
operations:
a) Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying ex-
cessive load to the brush. The wire bristles
can easily penetrate light clothing and/or skin.
b) Allow brushes to run at operating speed for
at least one minute before using them. Du-
ring this time no one is to stand in front or in
line with the brush. Loose bristles or wires will
be discharged during the run-in time.
c) Direct the discharge of the spinning wire
brush away from you. Small particles and tiny
wire fragments may be discharged at high ve-
locity during the use of these brushes and may
become imbedded in your skin.
Description of the machine and intended use
The PROXXON industrial straight grinder IGS/A in
combination with the matching bits and cutters is
perfectly suited for grinding, brushing, rust removal,
deburring, abrasive cutting and many other appli-
cations involving the machining of e.g. steel, non-
ferrous metal, glass, wood, minerals and ceramics.
The centrically clamped three-jaw chuck can ac-
commodate tool shafts with diameters of up to
6.5 mm
