Reaming With No. 744 Reamer; Threading Pipe - RIDGID 1224 Manual De Instrucciones

1224 Threading Machine
2. Tighten the cutter feed screw handle to bring the
cutter wheel firmly in contact with the pipe while
keeping the cutter wheel aligned with the mark on the
pipe.
3. Move the REV/OFF/FOR switch to the FOR position.
4. With both hands, grasp the pipe cutter feed handle
(Figure 21).
5. Depress the foot switch.
6. Tighten the feed screw handle one-half turn per rota-
tion of the pipe until the pipe is cut. More aggressive
tightening of the handle reduces cutter wheel life
and increases pipe burr formation. Do not support the
pipe by hand. Let the cut off piece be supported by
the threading machine carriage and pipe stand.

7. Remove foot from the foot switch.
8. Move the REV/OFF/FOR switch to the OFF position.
9. Raise cutter into position up away from operator.

Reaming with No. 744 Reamer

1. Move the reamer into reaming position. Make sure
that it is securely positioned to prevent it from moving
during use.
2. Move the REV/OFF/FOR switch to the FOR position.
3. With both hands, grasp the carriage handwheel.
4. Depress the foot switch.
5. Turn carriage handwheel to move the reamer to the
end of the pipe. Apply slight pressure to the hand-
wheel to feed the reamer into pipe to remove the burr
as desired.

6. Remove foot from the foot switch.
7. Move the REV/OFF/FOR switch to the OFF position.
8. Move the reamer up away from the operator.

Threading Pipe

Due to differing pipe characteristics, a test thread should
always be performed before the first thread of the day or
when changing pipe size, schedule or material.
1. Lower the die head into the threading position. Con -
firm that the dies are correct for the pipe being thread-
ed and properly set. See the "Die Head Set-Up and
Use" section for information on changing and adjust-
ing dies.
2. Close the die head.
3. Choose the correct operating speed for the applica-
tion.
4. Move the REV/OFF/FOR switch to the FOR posi-
tion.
5. With both hands, grasp the carriage handwheel.
6. Depress the foot switch.
7. Confirm cutting oil flow through the die head.
8. Turn carriage handwheel to move the die head to the
end of the pipe. Apply slight force to the handwheel to
start the die head onto the pipe. Once the die head
starts threading the pipe, no more force is required on
the carriage handwheel.
When using the 714/914 die head to make a tapered
thread, once the release foot actuates the receding
mechanism, if the die head is moved away from the
pipe, you will cut an oversized thread.
