2. Inspect the pipe to be threaded and associated fittings.
Determine the correct equipment for the job, see
Specifications. Do not use to thread anything other
than straight stock. Do not thread pipe with fittings or
other attachments. This increases the risk of entan-
glement.
3. Transport equipment to work area. See Preparing
Machine for Transport for information.
4. Confirm equipment to be used has been properly
inspected and assembled.
5. Confirm that the REV/OFF/FOR switch is in the OFF
position.
6. Check that the correct dies are in the die head and
are properly set. If needed, install and/or adjust the
dies in the die head. See Die Head Set-Up and Use
section for details.
7. Swing the cutter, reamer and die head up away from
the operator. Make sure they are stable and will not
fall in the work area.
8 If pipe will extend past the chip tray in the front of the
machine or more than 2' (0.6 m) out of the rear of the
machine, use pipe stands to support the pipe and
prevent the pipe and threading machine from tipping or
falling. Place the pipe stands in line with machine
chucks, approximately
pipe to the machine. Longer pipe may need more
than one pipe stand. Only use pipe stands designed
for this purpose. Improper pipe supports or supporting
the pipe by hand can cause tipping or entanglement
injuries.
9. Restrict access or set-up guards or barricades to
create a minimum of 3' (1 m) clearance around the
threading machine and pipe. This helps prevent non-
operators from contacting the machine or pipe and
reduces the risk of tipping or entanglement.
10. Position the foot switch as shown in Figure 18 to al low
a proper operating position.
11. Check the level of RIDGID Thread Cutting Oil. Re -
move the draw tray assembly and insert assembly;
see that the filter screen assembly is fully submerged
in oil. See Oil System Maintenance.
12. With the REV/OFF/FOR switch in OFF position, run
the cord along a clear path. With dry hands, plug
the power cord into the properly grounded outlet.
Keep all connections dry and off the ground. If the
power cord is not long enough use an extension
cord that:
• Is in good condition.

• Has a three-prong plug like on the threading
machine.
• Is rated for outdoor use.
• Has sufficient wire size. For extension cords up to
50' (15.2 m) long use 14 AWG (2.5 mm
For extension cords 50'-100' (15.2 m - 30.5 m) long
use 12 AWG (2.5 mm
13. Check the Threading Machine for proper operation.
With hands clear:
• Move the REV/OFF/FOR switch to the FOR posi-
tion. Press and release the foot switch. Chuck
should rotate counter-clockwise when viewed from
the carriage end (see Figure 22.) Repeat for REV
position – chuck should rotate clockwise. If the
threading machine does not rotate in the correct
direction, or the foot switch does not control the
machine operation, do not use the machine until it
has been repaired.
• Depress and hold the foot switch. Inspect the mov-
ing parts for misalignment, binding, odd noises or
any other unusual conditions. Remove foot from the
foot switch. If any unusual conditions are found, do
not use the machine until it has been repaired.
• Place die head in the use position. Depress and
hold the foot switch. Check for oil flow through the
die head. Remove foot from the foot switch. If
needed, see "Oil System Maintenance" section.
14. Move the REV/OFF/FOR switch to the OFF posi-
tion, and with dry hands unplug the machine.
die Head Set-up and use
The 1224 Threading Machine can be used with a variety
of RIDGID Die Heads to cut pipe and bolt threads. See the
RIDGID catalog for available die heads.
Die Heads require one set of dies for each of the following
pipe size ranges: (
1
/
" and
3
/
4
and (2
1
/
" through 4"). NPT/NPSM dies must be used in
2
NPT die heads and BSPT/BSPP dies must be used n
BSPT die heads – The size bar is marked for each.
Die heads using Bolt dies require a dedicated set of dies
for each specific thread size.
See the RIDGID catalog for dies available for your die
head.
Always cut a test thread to confirm proper thread size after
changing/adjusting the dies.
