LOWER ROLL INSTALLATION FOR
2-INCH/60.3-MM AND LARGER SIZES
NOTICE
• The arbor must be installed prior to
installing 2-inch/60.3-mm and larger size
lower rolls. Refer to the “Arbor Installation
Procedure for 2-inch/60.3-mm and Larger
Sizes” section.
1.
Install the lower roll onto the arbor.
Reposition the roll guards, if necessary, to
ease installation. Align the square drive of
the lower roll with the square drive of the
arbor.
2.
Install the flat washer and large nut onto
the threaded arbor stud. Fasten the large
nut securely with a wrench to set the lower
roll. DO NOT over-tighten the large nut.
3.
Roll set installation is now complete. Before
grooving, ensure that all instructions in the
previous sections of this manual have been
followed (i.e. adjusting the roll guards,
adjusting the groove diameter stop).
TRAVEL STOP KNOB INSTALLATION
This applies for the following sizes:
3/4 inch/26.9 mm NPS size
1 to 11/2 inch/33.7 to 48.3 mm NPS sizes
2 to 31/2 inch/60.3 to 101.6 mm NPS sizes
2 to 6 inch/54.0 to 155.6 mm copper tubing
sizes
NOTICE
• When roll grooving pipe sizes other than
what is listed above, the travel stop knob
must not be used. Store the travel stop
knob in the tool cabinet when not in use.
• The
3/8
– 16 UNC travel stop knob must
never replace the
1/2
– 13 UNC socket
head cap screw that limits return travel of
the arm/upper roll assembly.
The travel stop knob is used to limit arm/upper
roll assembly retraction, which minimizes upper
roll travel distance and improves grooving
productivity.
