Operation Using Machine-Mounted Tools; Installing Pipe In Threading Machine; Cutting Pipe With No. 820 Cutter - RIDGID 535 Manuel

• Flip the directional switch to FOR (Forward). Press
and release the foot switch. Check that the Thread -
ing Machine rotates in a counterclockwise direction
as you are facing the front chuck. Have the Thread -
ing Machine serviced if it rotates in the wrong
direction or if the foot switch does not control its
stopping or starting.
• Depress and hold the foot switch. Inspect the mov-
ing parts for misalignment, binding, odd noises or
any other unusual conditions that may affect the safe
and normal operation of the machine. If such con-
ditions are present, have the power drive serviced.
• Flip the directional switch to REV (Reverse). Press
and release the foot switch. Check that that Thread -
ing Machine rotates in a clockwise direction as
you are facing the chuck.
• Release the foot switch and flip the directional
switch to OFF.
Operation Using
Machine-Mounted Tools
WARNING
Do not wear gloves or loose clothing when operat-
ing Threading Machine. Keep sleeves and jackets
buttoned. Do not reach across the machine or pipe.
Do not use this Threading Machine if the foot switch
is broken or missing. Always wear eye protection to
protect eyes from dirt and other foreign objects.
Keep hands away from rotating pipe and fittings.
Stop the machine before wiping pipe threads or
screwing on fittings. Allow the machine to come to
a complete stop before touching the pipe or
machine chucks.
Do not use this machine to "make-on" or "break
off" fittings. This practice is not an intended use of
this Threading Machine.

Installing Pipe In Threading Machine:

1. Check to insure the cutter, reamer and die head are
swung to UP position.
2. Mark the pipe at the desired length if it is being cut to
length.
3. Insert the pipe into the Threading Machine so that the
end to be worked or the cutting mark is located about
12 inches to the front of the speed chuck jaws.

4. Insert workpieces less than 2 feet long from the front
of the machine. Insert longer pipes through either
end so that the longer section extends out beyond the
rear of the Threading Machine.
To avoid equipment tip-overs, position
WARNING
the pipe supports under the workpiece.
NOTE! For plastic and coated work pieces, special jaw
inserts (No. 97365) should be used to prevent
damaging the workpiece.
5. Tighten the rear centering device around the pipe by
using a counterclockwise rotation of the handwheel at
the rear of the Threading Machine. This prevents move-
ment of the pipe that can result in poor thread quality.
6. Secure the pipe by using repeated and forceful coun-
terclockwise spins of the speed chuck handwheel
at the front of the Threading Machine. This action
"hammers" the jaws tightly around the pipe.

Cutting Pipe with No. 820 Cutter

1. Swing reamer and die head to UP position.
2. Move pipe cutter DOWN onto pipe and move car-
riage with handwheel to line up cutter wheel with
mark on pipe.
NOTE! If using length gauge on machine carriage, place
cutter wheel against end of stock and set point to
"0". Raise cutter to clear stock and turn carriage
handwheel until pointer is at length desired.
3. Tighten cutter feed screw handle on pipe keeping
wheel aligned with the pipe. (Figure 5)

4. Assume the correct operating posture.
This will allow you to maintain proper bal-
