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 rtctechservices@emer -
son.com regarding a retrofit policy.
To prime the Model A Pump, the following procedure
should be followed:
1. Remove button plug located on cover.
2. Remove primer screw through opening with allen
wrench.
3. Fill pump with oil.
