ped. These wheels will grab if they become
slightly canted in the groove, and can kickback.
When a cut-off wheel grabs, the wheel itself
usually breaks. When a rotary fi le, high-speed
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 abra-
sive 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 eliminate 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 restar-
ted 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.
Description of the machine and intended use
The PROXXON cordless long neck straight grinder
LGS/A is designed for exterior and interior grinding
using high-grade corundum grinding bits.
Any other use of the device is considered improper
and involves considerable risk of accident or injury
and must therefore be avoided.
The long neck makes the device especially suitable
for machining in cavities that are diffi cult to access,
such as the inside of pipes, deep holes and cavities.
