6. To prolong the life of the machine and ensure a fi rst
class fi nish, it is important that the machine should not
be overloaded by applying too much pressure. In most
applications, the weight of the machine alone is suffi cient
for eff ective grinding. Too much pressure will result in
reduced rotational speed, inferior surface fi nish, and
overloading which could reduce the life of the machine.
7. 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.
8. Be sure to switch OFF and disconnect the attachment
plug from the receptacle to avoid a serious accident
before the depressed center wheel is assembling and
disassembling.
9. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.
10. Do not operate from a direct current power source,
booster or any other type of transformer. Doing so may
not only cause damage to the grinder, but may lead to
accidents.
11. Some mobile generators may not be usable with the
machine.
