3a.
Unlock the depth adjuster from the depth
adjuster lock.
3b.
Align the top edge of the depth adjuster
with the lowest line position of the proper
size and schedule markings.
3c.
Hold the depth adjuster to prevent it from
turning.
3d.
Turn the depth adjuster lock
counterclockwise to lock the depth adjuster
in this position. Back off the depth adjuster
lock. Align the depth adjuster with the
proper diameter and thickness indicated
on the pipe size indicator. Lock the depth
adjuster in position with the depth adjuster
lock.
NOTICE
• Rotating the depth adjusters while locked
will cause premature thread wear of the
depth adjusters and cylinder ram.
• The markings provide an approximate
groove diameter adjustment and are not
exact groove diameter settings. Variations
in pipe OD and wall thickness make
it impossible to calibrate the groove
diameter stop exactly.
• Set the initial adjustment shallow (at
bottom edge of mark), groove a sample
piece of pipe, then make the final
adjustment.
4.
Set the selector valve on the front of the
tool to the color that matches the pipe size
and schedule (RED or BLACK) on the pipe
size indicator label.
NOTICE
• The selector valve affects only the
maximum pressure at which the upper
roll forms the groove. It does not affect
the rate at which the upper roll advances
toward the pipe at the start of grooving,
nor the rate at which the roll retracts from
the pipe at the completion of the groove.
• Ram pressure during formation of the
groove can have a significant effect
on pipe-end flare. The recommended
settings will produce accurate grooves
in most situations. If excessive pipe-end
flare or stalling of the drive motor occurs
during operation in the high ram pressure
or “RED” setting, change the selector
valve setting to the low ram pressure or
“BLACK” setting.
