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.
When wheel is binding or when interrupting
3.
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.
Support panels or any oversized workpiece to
5.
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:
1. Do not use excessively oversized sanding
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.
2. If the use of a guard is recommended for wire
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:
When using depressed centre grinding wheels,
1.
be sure to use only fiberglass-reinforced
wheels.
NEVER USE Stone Cup type wheels with this
2.
grinder. This grinder is not designed for these
types of wheels and the use of such a product
may result in serious personal injury.
Be careful not to damage the X-LOCK holder.
3.
Damage to the parts could result in wheel
breakage.
Make sure the wheel is not contacting the
4.
workpiece before the switch is turned on.
5. 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.
6. Use the specified surface of the wheel to per-
form the grinding.
7. Do not leave the tool running. Operate the tool
only when hand-held.
Do not touch the workpiece immediately after
8.
operation; it may be extremely hot and could
burn your skin.
Observe the instructions of the manufacturer
9.
for correct mounting and use of wheels.
Handle and store wheels with care.
10. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
11. Check that the workpiece is properly
supported.
12. Pay attention that the wheel continues to
rotate after the tool is switched off.
13. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
14. Do not use the tool on any materials contain-
ing asbestos.
15. When use cut-off wheel, always work with
the dust collecting wheel guard required by
domestic regulation.
16. Cutting discs must not be subjected to any
lateral pressure.
17. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.
18. Before operation, make sure that there is no
buried object such as electric pipe, water pipe
or gas pipe in the workpiece. Otherwise, it may
cause an electric shock, electrical leakage or gas
leak.
SAVE THESE INSTRUCTIONS.
