PRACTICAL CUT-OFF MACHINE APPLICATION
1. Cutting force
To prolong the life of the machine and ensure a first class finish. It is important that the
machine should not be overloaded by applying too much force.
2. Precautions immediately after finishing operation
After switching off the machine, do not put it down until the cutting 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:
After operation, always place the machine so that the cutting wheel faces upward.
When the machine is not in use, the power source should be disconnected.
