Max 10660 Instruction Manual page 58

• Always feed the bit into the material in
the same direction as the cutting edge
is exiting from the material (which is the
same direction as the chips are thrown).
Feeding the tool in the wrong direction
causes the cutting edge of the bit to
climb out of the work and pull the tool in
the direction of this feed.
• When using cut-off wheels, always have
the work securely clamped. 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 the rotary � le, high-
speed cutter or tungsten carbide cutter
grab, it may jump from the groove and
you could lose control of the tool.
Safety warnings speci� c for grinding and
abrasive cutting-off operations
• Use only wheel types that are
recommended for your power tool and
only for recommended 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.
• For threaded abrasive cones and plugs
use only undamaged wheel mandrels
with an unrelieved shoulder � ange that
are of correct size and length. Proper
mandrels will reduce the possibility of
breakage.
• Do not "jam" a cut-off wheel or apply
excessive pressure. Do not attempt
to make an excessive depth of cut.
Overstressing the wheel increases the
loading and susceptibility to twisting or
snagging of the wheel in the cut and the
possibility of kickback or wheel breakage.

• 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.
• 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 complete stop. Never attempt
to remove the cutoff 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.
• 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.
• 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.
• 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.
