4.4

Fitting and replacing grinding tools

Warning!

Disconnect the electrical supply, when changing tools or repairing the machine.

Warning!

During grinding, the tools become very hot. Tip the machine back and allow it
to stand for a short while. Use protective gloves when removing the tools.

Warning!

When using tools with few points of contact with the surface, e.g. single
segment tools, there is a risk that the ground surface will not be even. For this
reason, such tools should be used with care and only when a roughly ground
surface will not spoil the finished result after grinding.
