Threading With 840A Universal Driveshaft (Rear Mount) - RIDGID 141 Manuel D'utilisation

6. Remove the ratchet and turn over. Rotate the drive-
shaft counterclockwise to back the die head up
approximately one turn.
7. Pull out cam plate knobs and rotate cam plate towards
the "CD" mark on top of the die head to re tract the
dies. This prevents the dies from dragging while
returning the geared threader to the start position.
8. Rotate drive shaft counterclockwise to back the die
head to the appropriate starting point for the next
thread.
9. Carefully remove the geared threader from the pipe
and inspect threads.
Threading with 840A Universal
Driveshaft (Rear Mount)
Using the 840A Universal Driveshaft, geared threaders
can be operated with 300/300A Power Drive, 535 and
1224 Threading Machines.
Do not attempt to use any other threading machine to
drive the geared threaders with 840A universal driveshaft.
Do not use auto-chucking threading machine (like 535A).
Do not use machines that do not have reverse rotation.
1. Make sure the geared threader is properly set up for
stationary pipe operation.
2. Make sure that the threading machine is unplugged
and the FOR/OFF/REV switch set to OFF. Follow all
warnings and instructions for the threading machine
3. Locate the threading machine so that the centerline of
the spindle lines up with the centerline of the pipe to
be threaded. The rear chuck of the threading machine
should be facing the pipe end to be threaded.

4. Insert the hex shaped end of the 840A Driveshaft into
the rear centering head of the threading machine.
Securely tighten the rear centering head and the
front chuck onto the flats of the universal driveshaft.

Guard
(Typical Both Ends)
Do not insert from the front (carriage) end of the
machine.
5. Align and slip the square socket of the 840A driveshaft
over the geared threader driveshaft. Tighten two
setscrews securely to hold in place. Make sure that
the driveshaft universal joint guards are in place and
in good condition (see Figure 9).
6. Inspect the position of the sliding shank in the drive-
shaft. It should be approximately centered to allow
movement in either direction. If needed, slightly adjust
the position of the threading machine. The centerline
of the threading machine should line up with center-
line of the pipe. If they are not aligned, this can cause
tipping of the threading machine.

7. If using a 300/300A Power Drive, secure it to the
floor to prevent tipping.
8. Set up guards or barricades to create a minimum of
one meter (three feet) of clearance around the equip-
ment and pipe. This helps to prevent non-operators
from accidentally contacting the machine or pipe and
causing tipping or becoming entangled in the rotating
parts.
9. Place the foot switch to allow a proper operating
position. With dry hands plug in the threading machine
and place the threading machine switch in REV posi-
tion.
10. Assume a proper operating position to help maintain
control of the machine and process (see Figure 11) .
• Stand on the FOR/OFF/REV switch side of the
threading machine with access to the switch.
• Be sure that you can control the foot switch. Do not
step on foot switch yet.
• Be sure that you have good balance and do not
have to overreach. Make sure that you are clear of
the driveshaft .
