535 Manual Pipe and Bolt Threading Machine
Installing Dies in
Model 816/817 Die Heads
The Semi-Automatic Die Head (Figure 11) for right hand
threads requires four sets of dies to thread pipe ranging
from 1 / " through 2". One set of dies is required for each
8
of the following pipe size ranges: (
and 3 / ") and (1" through 2"). Bolt threading requires a
4
separate set of of dies for each bolt size.
1. Depress handle so that camplate rests (Figure 8 –
Model 816/817 Die Head) against the stop. (As
shown).
2. Lay the Die Head down flat on a table or bench
with the numbers facing up.
3. Pull up on the plunger knob and push the handle all
the way to the left.
4. Select the correct dies for the size desired. (Size
marked on the back end or face of the dies.)
5. Numbers on the Dies must correspond with those on
the Die Head Slots. Insert Dies to the line marked on
the Dies – numbered edge up.
6. Rotate the handle back to the right so that the plunger
knob pops back down flush against the Die Head.
7. To set or adjust for desired depth of cut, loosen
the screw for the desired position block size, move
the block to the right to make it Under-Size and to
the left to make it Over- Sized. When setting blocks
for new dies start with the position block on the
middle mark and adjust from there.

Checking Thread Length

(Figure 12)
1. Thread is cut to proper length when end of pipe is
flush with edge of dies (Figure 12).
2. Die head is adjustable to obtain proper thread diam-
eter. If possible, threads should be checked with a
thread ring gage (Figure 12). A proper thread is cut
when end of pipe is plus or minus one turn of being
flush with face of ring gage.

NOTE! If a ring gage is not available, a fitting can be
used. This fitting should be representative of
those being used on the job. The pipe thread
should be cut to obtain 2 or 3 turns hand tight
engagement with fitting. If pipe thread is not prop-
er diameter the index line should be moved in the
direction of the OVER or UNDER size mark on
size bar. (Refer to "Installing Dies In Die Heads").

Priming Oil Pump

Current 535 Machines have a self-priming gerotor-type
pump. Machines made prior to June 1, 1996 have a
Model A vane-type pump that may require priming.
WARNING
All 535 Threading Machines made prior to June 1, 1996
should have a tube extension on the oil pump priming
port, as well as a top cover access hole, so the pump can
be primed without removing the top cover of the machine.
This will prevent the operator from contacting the internal
gearing of the machine which could result in serious injury.
If your older-style machine has a Model A Vane-Type pump
and does not have a priming port, contact the Ridge Tool
Company at 1-800-519-3456 or e-mail techservices@rid-
gid.com regarding a retrofit policy.
