precautions are taken.
b) Use special care when working
corners, sharp edges etc. Avoid
bouncing and snagging the
accessory. Corners, sharp edges or
bouncing have a tendency to snag the
rotating accessory and cause loss of control
or kickback.
c) Do not attach a toothed saw
blade. Such blades create frequent
kickback and loss of control.
d) 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.
e) When using rotary files, cut-off
wheels, high-speed cutters or
tungsten carbide cutters, 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 a rotary
file, high-speed cutter or tungsten carbide
cutter grabs, it may jump from the groove
and you could lose control of the tool.
ADDITIONAL SAFETY
INSTRUCTIONS
FOR GRINDING
AND CUTTING-OFF
OPERATIONS
Safety warnings specific for grinding
and abrasive cutting-off operations:
a) 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
28
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 unrelieved
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 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.
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 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 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 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.
