Description
The RIDGID ® Universal Semi-Automatic Die Heads include
Model 816 NPT and 817 NPT Die Heads. These die heads can
be quickly adjusted from size to size and are manually opened
for user specified thread length. The die heads operate with a
system of four Position Blocks on the cam plate. Each block can
be adjusted and set independently, allowing the operator to
change sizes quickly and accurately.
The 816 Die Head is for
2" size range. Both use RIDGID Universal dies.
The Semi-Automatic Die Heads can be used on RIDGID equip-
ment such as the 1215, 1233 535, 535A, 300 Compact Thread -
ing Machines and 300 Power Drive.

Inspection/Maintenance
Clean the die head to aid inspection and improve control.
Inspect the die head before each use for proper assembly,
wear, damage or other issues that could affect safe use.
Inspect the cutting edges of the dies. Dull or damaged cutting
tools increase required force, produce poor quality threads
and increase the risk of injury. If any problems are found, do not
use until corrected.
Set-Up/Operation
Make sure all equipment is inspected and set up per its instruc-
tions.
