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 brush-
ing, 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. When using depressed centre grinding wheels,
be sure to use only fiberglass-reinforced wheels.
2. 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.
3. Be careful not to damage the spindle, the flange (espe-
cially the installing surface) or the lock nut. Damage to
these parts could result in wheel breakage.
4. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
Before using the tool on an actual workpiece,
5.
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.
Do not leave the tool running. Operate the tool
7.
only when hand-held.
8. Do not touch the workpiece immediately after opera-
tion; it may be extremely hot and could burn your skin.
9. Observe the instructions of the manufacturer
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. Use only flanges specified for this tool.
12. 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.
13. Check that the workpiece is properly supported.
14. Pay attention that the wheel continues to
rotate after the tool is switched off.
15. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-cir-
cuit breaker (30 mA) to assure operator safety.
16. Do not use the tool on any materials contain-
ing asbestos.
17. When use cut-off wheel, always work with the dust col-
lecting wheel guard required by domestic regulation.
18. Cutting discs must not be subjected to any
lateral pressure.
19. Do not use cloth work gloves during operation. Fibers from
cloth gloves may enter the tool, which causes tool breakage.
SAVE THESE INSTRUCTIONS.
