Basic Machining
1.
Turn the motor(s) on to full speed.
2. Push the Tripper Shaft in to engage the feed.
DANGER
DANGER: Wait for the rotating tool block to pass the tripper block before you push the
tripper shaft. If your hand is in the path of the tool block, before it passes the tripper
block, this can result in serious personal injury.
DANGER: Do not put your hands or other parts of your body on the drive housing or
the tripper bracket assembly when the head stock is rotating. Serious personal injury
can occur.
3. Monitor the cutting operation.
4.
Apply cutting fluid as necessary.
DANGER
DANGER: Do not remove chips when the tool is moving. Your hand or other parts of
your body can be caught in rotating components. Serious injury or death could result.
DANGER: The chips have sharp edges and can cut or puncture your skin. Wear gloves
and be careful when you remove the chips.
5.
If there are so many chips that they tangle in the Clamshell, disengage the
feed for 2-3 revolutions, and then stop the Clamshell and remove the chips.
6.
Before you finish the cut, examine the supports and the scaffolds to be
sure that nothing will move after the pipe is severed.
WARNING
WARNING: If the pipe or equipment moves as the cut is completed, do not try to stop
them by holding them. Holding a moving pipe or moving equipment may cause injury to
the operator and others.
7.
After the machining operation is finished, disengage the Tripper Shaft by pulling
it to the ‘out’ position.
8. Allow the Headstock to continue for three revolutions to complete cutting.
9. Turn off the motor(s).
10.
Retract the Tool Holder(s) to let the Tool Bit(s) clear the pipe OD.
11.
Retract The Tool Holder(s) rotating the Feed Sprocket Shaft clockwise using
the hex wrench supplied with the Clamshell.
2. Tighten the Tool Bit Set Screws.
3. Do a full rotation of the Headstock to be sure there is adequate radial clearance.
4. Be sure that the Leading Tool Bit contacts the pipe approximately .020”
(.51 mm) to .040” (1.02 mm) before the Trailing Tool Bit.
