4. 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.
5. Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
1. Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
The grinding surface of centre depressed
2.
wheels must be mounted below the plane of
the guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot
be adequately protected.
3. The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect
the operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could
ignite clothing.
4. Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
5. 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.
6. 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:
1. Do not "jam" the cut-off wheel or apply exces-
sive 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 possibil-
ity of kickback or wheel breakage.
2. 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 spin-
ning wheel and the power tool directly at you.
3. 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 correc-
tive action to eliminate the cause of wheel binding.
4. 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.
5. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. 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.
6. Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
Do not use excessively oversized sanding
1.
disc paper. Follow manufacturers recommen-
dations, 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:
1. 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.
If the use of a guard is recommended for wire
2.
brushing, do not allow any 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:
1. Always install the dust collecting wheel guard
before operation as a concrete planer.
2. When using depressed centre grinding wheels,
be sure to use only fiberglass-reinforced
wheels.
3. NEVER USE Stone Cup type wheels when
using as a grinder. This tool is not designed for
these types of wheels and the use of such a prod-
uct may result in serious personal injury.
4. 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.
5. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
6. 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.
7. Use the specified surface of the wheel to per-
form the grinding.
8. Do not leave the tool running. Operate the tool
only when hand-held.
Do not touch the abrasive wheel and the work-
9.
piece immediately after operation; it may be
extremely hot and could burn your skin.
10. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
