Changing Operating Speeds; Carriage Handwheel Adjustment; Cutting With No. 764 Cutter - RIDGID 1224 Manual

Figure 18 – Operating Position
6. Assume a proper operating position to help maintain
control of the machine and pipe (See Figure 18).
• Stand on the REV/OFF/FOR switch side of the
machine with convenient access to the tools and
switch.
• Be sure that you can control the foot switch. Do not
step on foot switch yet. In case of emergency, you
must be able to release the foot switch.
• Be sure that you have good balance and do not
have to overreach.

Changing operating Speeds

The 1224 has two operating speeds – 12 and 36 rpm. 36
rpm can be used for cutting and reaming pipe up to 4"
and threading pipe threads up to 2". 12 rpm should be
used to thread 2 1 / " and larger pipe threads or other high
2
torque applications such as stainless steel, high hardness
material, etc. If 1224 ever stalls while operating at 36
rpm, immediately release foot switch and change speed
to 12 rpm.
Do not change operating speed while cutting, reaming or

threading. Any load on machine could prevent shifting of
gears. To change operating speed:
1. Move the REV/OFF/FOR switch to the FOR position.
2. Depress and release the foot switch to start the
chuck rotating.
3. While the chuck is rotating (but the foot switch is
released) move the shift knob.
These steps match those on the speed selector decal
(Figure 19).

Carriage Handwheel Adjustment

The 1224 carriage handwheel position can be adjusted for
better leverage.
1. Pull handwheel out from carriage.
2. Rotate the handwheel ¼ turn. The handle will auto-
matically reengage in new position.

Cutting with No. 764 Cutter

1. Open cutter by turning the feed screw counterclock-
wise. Lower the cutter into cutting position over the
pipe. Use the carriage handwheel to move the cutter
over the area to be cut, and align the cutter wheel with
the mark on the pipe. Cutting threaded or damaged
sections of pipe can damage the cutter wheel.
