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.
21. Safety Warnings
Operations:
a) Do not use excessively oversized sanding
disc paper.
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.
22. 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.
23. When using depressed centre grinding wheels,
be sure to use only fiberglass-reinforced
wheels.
24. 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.
25. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
26. 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.
27. Use the specified surface of the wheel to
perform the grinding.
28. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
29. Do not leave the tool running. Operate the tool
only when hand-held.
30. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
31. 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.
Specific for Sanding
Follow manufacturers
32. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
33. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
34. Use only flanges specified for this tool.
35. 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.
36. Check that
supported.
37. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
38. Pay attention that the wheel continues to
rotate after the tool is switched off.
39. 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.
40. Do not use the tool on any materials
containing asbestos.
41. Do not use water or grinding lubricant.
42. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary
disconnect the tool from the mains supply
( use non metallic objects ) and avoid
damaging internal parts.
43. When use cut-off wheel, always work with the
dust collecting wheel guard required by
domestic regulation.
44. Cutting discs must not be subjected to any
lateral pressure.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
