Before you mount the equipment, consider the following:
• Is the selected pipe lathe suitable for the task?
• Is there enough space for the equipment and personnel to do the task
safely?
• Is enough support in place for the severed pipe and the remaining section?
• Is there enough scaffolding to access the pipe section to be cut?
• Is there enough clearance for the pipe to rotate?
• Is the power source for the pipe lathe accessible?
• Does the clamshell have enough clearance to fully rotate without
obstruction?
Mount the Tool Blocks and Tripper Bracket
• Mount the Tool Blocks in either location. You can apply the Tool Blocks before
you mount the Clamshell halves to the pipe.
DANGER
DANGER: Wait for the rotating tool block to pass the tripper block before you push the
tripper shaft. This reduces the risk of 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. This reduces the risk of
serious personal injury.
CAUTION
CAUTION: Do not install cutting tools, like the tool bits, until the clamshell halves are
mounted on the pipe or the equipment will be damaged.
Do not let the tripper shaft strike the sprocket tooth straight on or the tripper shaft and
the sprocket may be damaged or broken.
1.
Unbolt the two Red Lock Blocks attached to the headstock.
DANGER
DANGER: When the red lock blocks are removed, the headstock will rotate freely. Do this
procedure on a work bench to prevent the headstock from rotating free of the clamshell.
2. Flip the Red Lock Blocks over and reattach them with the dowel pin pointing
outward. The headstock is now free to rotate.
3.
Examine the engagement of the Tripper Shaft to the Sprocket, refer to Fig. 10.
