5. 141 and 161 – Release foot switch when red STOP
line appears on pinion sleeve (Figure 17).
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) position.
Step on foot switch and back threader off of pipe.

Threader (Close-Coupled Method)
(No. 161 Threader Similar)
IMPORTANT! Allow approximately
3
/
4
″ of V-shaped
grooves exposed in front of chuck jaws
(Figure 17) to allow space for oiling.
7. 141 and 161 – Using the socket wrench, loosen
clamp screw (Figure 16) , 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 Threader
is backed off too far and threaded barrel
becomes disengaged from workholder, the
threader must be removed form the Power
Drive and put on a bench. Re-engage the
threads carefully by hand. Do not attempt
this by power.
