intended for peripheral grinding, side forces applied
to these wheels may cause them to shatter.
d)
Always use undamaged wheel flanges that
are of correct size and shape for your selected
wheel.
Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel flanges.
e)
Do not use worn down wheels from larger
power tools.
Wheel intended for larger power tool
is not suitable for the higher speed of a smaller tool
and may burst.
Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
a)
Do not “jam” the 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 binding of the wheel in the cut and the possibility
of kickback or wheel breakage.
b)
Do not position your body in line with and
behind the rotating wheel.
When the wheel, at
the point of operation, is moving away from your
body, the possible kickback may propel the
spinning wheel and the power tool directly at you.
c)
When wheel is binding 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 binding
d)
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.
e)
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.
f)
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.
Safety Warnings Specific for Sanding Operations:
a)
Do not use excessively oversized sanding
disc paper. Follow manufacturers
recommendations, when selecting sanding
paper.
Larger sanding paper extending beyond the
sanding pad presents a laceration hazard and may
cause snagging, tearing of the disc or kickback.
Safety Warnings Specific 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 excessive
load to the brush.
The wire bristles can easily
penetrate light clothing and/or skin.
b)
If the use of a guard is recommended for
wire brushing, do not allow interference of the
wire wheel or brush with the guard.
Wire wheel
or brush may expand in diameter due to work load
and centrifugal forces.
Additional safety warnings:
17.
When using depressed centre grinding wheels,
be sure to use only fiberglass-reinforced
wheels.
18.
NEVER USE Stone Cup type wheels with this
grinder.
This grinder is not designed for these
types of wheels and the use of such a product
may result in serious personal injury.
19.
Be careful not to damage the spindle, the
flange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
20.
Make sure the wheel is not contacting the
workpiece before the switch is turned on.
21.
Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
22.
Use the specified surface of the wheel to
perform the grinding.
23.
Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
24.
Do not leave the tool running. Operate the tool
only when hand-held.
25.
Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
26.
Always be sure that the tool is switched off
and unplugged or that the battery cartridge is
removed before carrying out any work on the
tool.
27.
Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
28.
Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
29.
Use only flanges specified for this tool.
30.
For tools intended to be fitted with threaded
hole wheel, ensure that the thread in the wheel
is long enough to accept the spindle length.
31.
Check that the workpiece is properly
supported.
32.
Pay attention that the wheel continues to
rotate after the tool is switched off.
