Rotating Pipe (Front Mount/Close Coupled) Set-Up; Setting Up 300/300A Power Drive Close Coupled To 141/161 Geared Threader - RIDGID 141 Operator's Manual

Model 141/161 Receding Geared Threaders
Figure 11 – Threading With Universal Driveshaft
11. Press the foot switch to start threading. Flood the dies
with oil to lower threading torque, improve thread
quality and increase die life. The geared threader
drive shaft will rotate around the pipe while threading,
so be prepared for the movement of the driveshaft. If
any problems are experienced step off of foot switch.
12. Continue threading until the edge of the die head is
flush with the red stop line on the pinion sleeve
(Figure 8) . Release foot switch. If threading is con-
tinued past the red stop line, the pinion shaft will
disengage to prevent jamming. Do not continue to
operate with the pinion shaft disengaged – over time
this can cause tool damage.
13. Put the FOR/OFF/REV switch in the FOR position.
Resume operating position and step on foot switch to
back die head off approximately one turn. Release
fooswitch and place FOR/OFF/REV switch in OFF
position.
14. Pull cam plate knobs out and rotate cam plate towards
the "CD" mark on top of the die head to retract the
dies. This prevents the dies from dragging while
returning the geared threader to the start position.
15. Put the FOR/OFF/REV switch in the FOR position.
Resume operating position and step on foot switch to
rotate the die head to the appropriate starting point for
the next thread.
16. Remove foot from the foot switch. Place the FOR/ -
OFF/ REV switch in the OFF position and unplug the
threading machine.

NOTICE If the workholder is unscrewed from the thread-
ed barrel, DO NOT try to re-engage the thread under

geared threader from the pipe and re-engage by hand.
Carefully remove the universal driveshaft and geared
threader from the pipe and inspect thread.
Rotating Pipe (Front
Mount/Close Coupled) Set-Up
1. Locate a work area that has:
• Adequate lighting.
• Clear level, stable, dry location for all of the equip-
ment and the operator.
2. Clean the work area before setting up any equip-
ment. Wipe up any oils or liquids.
3. Inspect the pipe to be threaded and associated fittings
and confirm that the 141 or 161 Geared Threader is
a correct tool for the job. See the Specifications.
Threading equipment for other applications can
be found in the RIDGID catalog on line at
www.RIDGID.com or www.RIDGID.eu.
4. Confirm that equipment to be used has been properly
inspected.
5. Set up the machine in clear, level space selected
for the work area following the threading machine
instructions. Check that the machine and stand are
stable. Make sure machine is unplugged and FOR/ -
OFF/REV switch is in the OFF position. If using with
the 300/300A Power Drive, remove carriage, die
head, reamer and cutter from the support bars. If
using a threading machine, remove the die head
from carriage, place the cutter and reamer up and
away, and move the carriage away from the chuck.
6. Fully open the front chuck and the rear centering
device on the machine.
7. Properly adjust the geared threader for the work to be
done. Make sure that the die head is correctly backed
off to make an appropriate sized thread. See "Adjust -
ing Geared Threaders" .
8. With the drive shaft of the geared threader up, attach
the 844 Drive Bar and securely tighten the two set -
screws to retain in place (See Figure 15) . For 535A
machine, do not attach drive bar at this time.
