Threading Pipe Using No. 141 Geared Threader (Close Coupled Method); Important; Installing Nos. 141 &161 Geared Threaders Using No. 840A Universal Drive Shaft; Threading Pipe Using Nos. 141 & 161 Geared Threaders With No. 840A Universal Drive Shaft - RIDGID 535 Manual De Operador

535 Manual Pipe and Bolt Threading Machine
Threading Using No. 141 Geared
Threader (Close-Coupled Method)
1. Install geared threader and pipe.
2. Turn Threading Machine REV/OFF/FOR switch to
FOR (Forward) position.
3. Step on foot switch.
4. Flood dies with RIDGID Thread Cutting Oil during
threading operation to assure long die life.
5. Release foot switch when red STOP line appears on
pinion sleeve (Figure 14).
NOTE! RIDGID Geared Threaders have a jam-proof
design so pinion shaft will automatically disen-
gage if threader is accidentally run on pipe past
a full thread length.
6. Turn REV/OFF/FOR switch to REV (Reverse) posi-
tion. Step on foot switch and back threader off of
pipe.
IMPORTANT: Do not loosen workholder until dies have
been disengaged from pipe.
7. Using the socket wrench, loosen clamp screw, turn
workholder to OPEN position and remove pipe.
NOTE!: Before threading next piece of pipe, run thread-
er head beyond STANDARD line on pinion
sleeve and then back to STANDARD line. This
movement takes up slack in gearing for imme-
diate response when cutting next thread.
8. Turn REV/OFF/FOR switch to OFF position.
IMPORTANT: If, by accident, a RIDGID Geared Thread-
er is backed off too far and threaded bar-
rel becomes disengaged from workhold-
er, the threader must be removed from
the Threading Machine and put on a
bench. Re-engage the threads carefully
by hand. Do not attempt this by power.

Threaders Using No. 840A Universal
Drive Shaft
WARNING
Chain vise must be securely anchored with jack
screw assembly and post to ceiling or bolted to
floor. Failure to follow these instructions could
result in the Vise tipping and causing serious injury.
When threading pipe up to 5 inches nominal, the
450 Tristand Vise can be used. However, when
threading 6 inch nominal pipe, a BC-610, BC-810
Top Screw Bench Chain Vise or a 460 Tristand
Vise must be used.
Only use 535 machines that operate at 36 RPM
when threading with a geared threader using the
No. 840A Universal Drive Shaft. Higher speeds
may result in tipping.
Refer to Figure 18.
1. Adjust threader being used.
WARNING
the OFF position until geared threader is set up and

4. Locate chain vise in line, on same level, and approx-
imately length of universal drive shaft away from
centering head device.
5. Tightly secure pipe in No. 460 Tristand Chain Vise.
6. Support long piece of pipe with Pipe Support.
7. Using two persons, position workholder so that a
jaw is on top center and slide threader onto pipe.
Carefully center end of pipe in throat of dies.
8. Using socket wrench, tighten workholder clamp screw
(Figure 13) securely.
9. Slip square socket of No. 840A Universal Drive Shaft
