5. Precautions immediately after fi nishing operation
The wheel continues to rotate after the tool is switched
off .
After switching off the machine, do not put it down until
the depressed center wheel has come to a complete
stop. Apart from avoiding serious accidents, this
precaution will reduce the amount of dust and swarf
sucked into the machine.
CAUTION
○ Check that the work piece is properly supported.
○ Ensure that ventilation openings are kept clear when
working in dusty conditions.
If it should become necessary to clear dust, fi rst
disconnect the tool from the mains supply (use non-
metallic objects) and avoid damaging internal parts.
○ Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite fl ammable
substances.
○ Always use eye and ear protection.
Other personal protective equipment such as dust
mask, gloves, helmet and apron should be worn when
necessary.
If in doubt, wear the protective equipment.
○ When the machine is not use, the power source should
be disconnected.
