tungsten carbide cutter grabs, it may jump from

tool.
SAFETY WARNINGS SPECIFIC
FOR GRINDING OPERATIONS
a) Use
only
wheel
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.
b) For threaded abrasive cones and plugs
use only undamaged wheel mandrels with
an unrelieved shoulder fl ange 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.
6
types
that
are
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.
h) 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.
GENERAL SAFETY
INSTRUCTIONS FOR GRINDERS
–
Check that speed marked on the wheel is
equal to or greater than the rated speed of the
grinder;
–
Ensure
that
the
compatible with the grinder;
–
Abrasive wheels shall be stored and handled
with care in accordance with manufacturer's
instructions;
–
Inspect the grinding wheel before use, do not
use chipped, cracked or otherwise defective
products;
–
Ensure that mounted wheels and points are
fi tted in accordance with the manufacturer's
instructions;
–
Ensure that blotters are used when they are
provided with the bonded abrasive product and
when they are required;
–
Do not use the power tool to machine materials
that contain components that are harmful to
health.
–
Ensure that the abrasive product is correctly
mounted and tightened before use and run the
tool at no-load for 30 s in a safe position, stop
immediately if there is considerable vibration
or if other defects are detected. If this condition
occurs, check the machine to determine the
cause;
–
If a guard is equipped with the tool never use
the tool without such a guard;
–
Do not use separate reducing bushings or
adapters to adapt large hole abrasive wheels;
–
For tools intended to be fi tted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length;
–
Secure the workpiece and check that the
workpiece is properly supported. A workpiece
clamped with clamping devices or in a vice is
held more securely than by hand;
–
Do not use cutting off wheel for side grinding;
