7-2) Adjustment of Thread Depth
■
for Beaver Die-Head 1/2"-2"AT,21/2"-4"
*
Loosen the Block Screw and move the Selector Block to adjust the thread depth. Sliding toward
H makes deeper threads and G makes, shallower threads. The thread depth will change by 1.5 to
2 threads under or over by one scale. (fig.34)

For Beaver Die-Head 1/2"-2"
(1)Set location plate to location block which is not fort he size to be adjusted.
(2)Loosen the screw and move location block to adjust the thread depth.
(3)Sliding toward “H” males deeper threads and sliding toward “G” makes shallower threads. The
thread depth will change 1.5 to 2 mm threads by one scale. (fig.35)
(4)With the aid of a measuring instrument, check the cut pipe for a tapered thread etc. and correct
the setting if necessary.
7-3) Two-Step Threading (For Beaver Die-Head 21/2" ~ 4")
* When threading a big diameter pipe under low voltage, use the Two-Step
to thread first then set the Selector Pin (Silver) for standard threading. (fig.36)
