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 instructions.
Always cut a test thread to confirm proper thread size after chang-
ing/adjusting the dies.

ranges: ( 1 / "), ( 1 / " and 3 / "), ( 1 / " and
