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 and increase the risk of injury. If any problems
are found, do not use until corrected.
Set Up and Operation
Make sure all equipment is inspected and set up per its instructions.
Always cut a test groove to confirm proper groove size after chang -
ing/adjusting the dies. See"Inspecting the Groove" section.
Inserting/Changing the Dies
The die head requires separate set of dies for (2
(4") pipe size ranges. A cut grooving die set consists of three guide dies
and one cutting die.
1. Place the die head with
numbers facing up.
2. Loosen the cam bolt nut
approximately six full turns.
3. Lift tongue of lever wash er
out of the slot and open
the die head by moving
the cam bolt in the direc-
tion of the larg est size pipe
on cam plate (Figure 2).
4. Remove dies from the die
head.

die head slots. Insert numbered edge/ notch facing up until the
indicator line on die is flush with the edge of the die head
(Figure 2).
6. Move cam bolt to align desired size mark with index line. Adjust die
insertion as needed to allow movement. Wash er tongue should
be in slot to left (Figure 1). Tighten the cam bolt nut.
Adjusting Pipe Size
Loosen the cam bolt nut and rotate cam locking plate to desired size
setting. Tighten the nut.
Cutting A Groove
Refer to the 1224 Threading Machine Operator's Manual for informa-
tion on machine set-up and operation. Cut grooving should be done
at 36 rpm.
1. On 1224, pull sine bar out away from the chuck and rotate the
latch down to hook it to the carriage.
2. Lower the die head into operating position.
3. Turn feed screw to retract dies and prevent die contact with pipe.
4. Move the REV/OFF/FOR switch to FOR position.
5. Turn the carriage handwheel to bring the die head stop against
end of pipe. Hold the handwheel in position to prevent the stop
from moving away from the pipe end. This sets the gasket seat
length of the groove.
6. Depress foot switch. Confirm oil flow through the die head.
7 . While holding stop against end of pipe, slowly turn the feed
screw assembly to feed groove die into pipe and cut groove.
Keep feedscrew end in contact with carriage.
8. Continue to advance feed screw until proper groove diameter is
reached. Allow pipe to make 3 to 4 revolutions to clean up any
extra material left in groove.
9. Set the adjustment nut against the cam locking plate and retain
with the jam nut for more repeatable groove size.
10. Once cutting operation is complete and while pipe is still rotating,
turn feed screw to retract grooving die clear of the pipe diameter.
11. Remove foot from the foot switch.
12. Move the FOR/OFF/REV switch to the OFF position.
13. Turn carriage handwheel to move the die head past end of the
pipe. Raise the die head into the position up away from the oper-
ator.
14. Remove the pipe from machine and inspect the groove.

Inspecting the Groove
1. Measure the groove diameter. Compare the dimension to the
requirement in Table I or as specified by the groove fitting manu-
facturer. Adjust adjustment nut and jam nut as needed. One
rotation of the adjustment nut changes groove diameter approx-
imately 0.02".
2. Measure gasket seat width. Compare the di men sion to the require-
ment in Table I or as specified by the groove fitting manufacturer.
3. Visually inspect the groove for form and other items required by the
fitting manufacturer. If any issues are found, the groove cannot be
used. Out of spe ci fi cation grooves could cause joint failure.
