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 Opera-
tions:
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 centrif-
ugal forces.
Additional Safety Warnings:
17. When using depressed center grinding wheels,
be sure to use only fiberglass-reinforced wheels.
18. 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.
19. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
20. 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.
21. Use the specified surface of the wheel to per-
form the grinding.
22. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
23. Do not leave the tool running. Operate the tool
only when hand-held.
24. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
25. 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.
26. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
27. Do not use separate reducing bushings or adap-
tors to adapt large hole abrasive wheels.
28. Use only flanges specified for this tool.
29. 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.
30. Check that the workpiece is properly supported.
31. Pay attention that the wheel continues to rotate
after the tool is switched off.
32. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.

33. Do not use the tool on any materials containing
asbestos.
34. Do not use water or grinding lubricant.
35. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply (use non metallic
objects) and avoid damaging internal parts.
36. When use cut-off wheel, always work with the
dust collecting wheel guard required by domes-
tic regulation.
37. Cutting discs must not be subjected to any lat-
eral pressure.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury
