CAUTION:
Adjust the cutting RPM with the Speed Control to just above the required cutting
speed as the Tool Bit enters the cut.
The Tool will slow down slightly as the cutting load increases, apply additional power
to hold the cutting speed.
Observe the chip as the machine is cutting.
The ideal chip will come off in a loose pig tail spiral.
A chip that is coming off in a tight straight spiral normally indicates that the feed is
too heavy.
A straight or slightly curled chip normally indicates that the feed is too light.
Back off the feed as required to break the chips and let them fall away.
If a significant amount of stock must be removed, occasionally back out of the cut
and let the Tool Bit spin free in the air to cool.
Continue rotating the Feed Handle clockwise until the end of the pipe is completely
machined.
Be careful not to let the Tool Bit cut into the Collet or the Collet Adapter.
Discontinue feed and allow the Cutting Head to rotate one time for stainless steel
and up to three times for other materials to improve the finish of the prep
surface.
Never let a Tool Bit ‘rub’ the surface of a stainless steel tube without cutting.
This will work harden the material and it will be difficult for the Tool Bit to get under
the material in order to finish the cut.
This will also cause excessive Tool Bit wear.
Rotate the Feed Handle counter-clockwise to separate the Cutting Head and the
pipe.
Stop the Cutting Head rotation.
Release the Trigger.
Rotate the Feed Knob counter-clockwise until the Cutting Head clears the tube or
