Ridgid C-888-X Operating Instructions
Ridge T ool Co., Elyria, Ohio, U.S.A.
Set Up and Threading Instructions
To Thread with a No. 141 Threader and 200, 300, 400 or 400A RIDGID Power Drive, equipment (A, B or D, C) must
be used. For operation set-up see Figure 1, below, with a 300 Power Drive.
2. RIDGID Close Coupled Method
This operation will require a RIDGID No. 318 Oiler in
addition to the items shown at top of page.
IMPORTANT: Do not plug Power Drive into electrical
outlet until steps 2-A through 2-D are
completed. When ready, make sure
Power Drive is plugged into an internally grounded electrical system. If
system is not internally grounded, then
ground Po wer Drive in accor dance with
Article 250 of the National Electrical
Code.
A. Adjust Threader to size as previously explained. With
Threader on floor or workbench with Drive Shaft up,
place No. 844 Drive Bar on Threader Drive Shaft and
tighten the two Set Screws in Drive Bar Head.
NOTE: Step B is a two man operation.
B. With No. 844 Drive Bar securely fastened to Threader
Drive Shaft, lift Threader up carefully and insert shaft
of Drive Bar into front chuck of Power Drive. While
one man holds Threader up, the other man tightens
the jaws of Power Drive with other hand. Jaws should
tighten into “V” shaped notches of No. 844 Drive Bar
to be correctly mounted. Close rear centering device
onto shaft of Drive Bar.
C. Correct location for No. 318 Oiler is directly under
Threader. The No. 46 Pipe Support should be no closer than approximately two and one-half feet from
Threader and in line so it will support pipe being threaded. At this time, depending upon which Threader is
being used, attach either No. 758 Loop or E-3675
Adapter Bracket to Threader. Slide support bar of
Power Drive through hole in either No. 758 Loop or E3675 Adapter Bracket.
D. Insert pipe in Threader and center end in throat of
Dies. Tighten W orkholder . Clamp Screw must be tightened SECURELY. You are now ready to thread.
IMPORTANT: Plug Power Drive into internally ground-
ed electrical system.
E. Move Switch of power drive to forward. During thread-
ing operation, flood Dies with RIDGID Thread Cutting
Oil to assure perfect threads and long die life.
F. When red “STOP” line appears on Pinion Sleeve,
thread is completed. Stop Threading! Reverse
Threader about one-quarter revolution by power, then
pull knobs and turn Cam Plate to “CD” mark on top of
Die Head. Unplug Power Drive cord from electrical
system. Pipe may be removed at this time by loosening Clamp Screw and turning Workholder Scroll to
“OPEN” position.
G. RIDGID Geared Threaders are designed so Pinion
Shaft will automatically disengage if Threader is accidentally run on pipe past a full thread length. This prevents jamming.
IMPORTANT . . .
If, by accident, a RIDGID Geared Threader is backed off
too far and threaded barrel becomes disengaged from
Workholder, the Threader must be put on a bench and
the threads re-engaged carefully by HAND, NOT BY
POWER.

Universal Drive Shaft Method
Do not plug Power Drive into electrical system until
steps A through E are completed.
A. This operation will require a RIDGID No. 840 Universal
Drive Shaft, Foot Switch, Geared Threader, Vise Stand
capable of holding size pipe being threader and a
Power Drive. When threading pipe larger than 2″,
Power Drive and Vise Stand must be securely
anchored, or provisions made to make sure Power
Drive and Vise Stand cannot tip over as a result of
threading torque built up. The Vise Stand must be in
line with, and on the same level as the front chuck of
Power Drive. The extended length of the No. 840
Universal Drive Shaft should be maximum distance
between Power Drive and Vise Stand.
B. Slide long hexagon end of Universal Drive Shaft into
front chuck of Power Drive. Tighten front chuck and
rear centering device.
C. Fasten pipe securely onto Vise Stand. Long pieces of
pipe should be supported by a RIDGID No. 92 Pipe
Support to prevent Vise Stand and Threader from tipping up.
D. After Threader is adjusted to size per instructions on
first page, slide Threader onto pipe. Carefully center
end of pipe in throats of Dies. Workholder clamp
screw must be tightened securely.
E. Slip square socket of No. 840 Universal Drive Shaft
over end of Threader Drive Shaft and tighten set
screws. When properly positioned, sliding shank of
Universal Drive Shaft should neither be fully extended
nor fully closed. At this time, take any other steps to to
insure stability of Vise Stand and Power Drive.
F. Locate Foot Switch as shown above and plug Foot
Switch cord into an internally grounder electrical system. Plug Power Drive cord into Foot Switch cord. Put
Power Drive switch into forward (FOR) position.
Operator should now locate Foot Switch and himself
as shown with Oiler in position. To operate this setup
safely, use Foot Switch at all times to start and stop
Power Drive.
NOTE: During Threading, use RIDGID Thread Cutting
Oil freely.
IMPORTANT: When changing any part of this setup
always unplug Foot Switch cord from
electrical system.
G. Threading is completed when red “STOP” line
appears on Pinion Sleeve. Stop Threading! Put Power
Drive switch in reverse (REV) and reverse Threader
about one-half turn by means of Foot Switch. Unplug
Foot Switch. Pull knobs on Threader and turn Cam
Plate to “CD” mark on top of Die Head. Loosen Clamp
Screw, turn W orkholder Scroll to “OPEN” position and
remove Threader from pipe.
