To open the die head manually (with trigger slide up), at

the end of the number 1 die.
• Bolt and Straight Threads – Thread the desired
length – watch closely for any interference between
the parts.
Move the throwout lever to the OPEN position, retracting
dies.

Insert appropriate dies into the die head, numbered
edge up. Numbers on the dies must correspond with
those on the die head slots (see Figure 16). The die
slots have a ball detent that engages with the groove
on dies when properly installed. Always change dies
as sets – do not mix dies from different sets.
4. Pull back on adjuster knob and rotate cam plate to
desired size setting.
5. Engage adjuster knob into slot.
1. Loosen the adjustment nut for the desired pipe size.
2. When setting for new dies,
start with the adjusting slide
index line aligned with the
size mark on the size bar.
3. If thread size needs to be
adjusted, set the index line
slightly off the mark on the
size bar in the + direction
(larger thread diameter, less
turns of fitting engage ment)
or in the - direction (smaller
thread diameter, more turns
of fitting engagement) as
shown on the size bar.
4. Tighten the adjustment nut.
1. Loosen the screw on bottom trigger.
2. For short threads, shift the bottom trigger towards
the machine spindle. For long threads, shift it away
from the spindle (see Figure 18 – factory settings
shown). Long threads are typically preferred in Far
East and short threads in Europe. Set as desired.
