• To manually rotate the pneumatic machine, insert a 10-mm hex wrench in
the hex opposite the motor or push on the end of the turning arm.
• To manually rotate the hydraulic machine, use the cross-connection hose
supplied with the machine to connect the #1 and #2 port hoses. Insert a 10-
mm hex wrench in the hex opposite the motor or push on the end of the
turning arm.
5.5.2 The machine isn’t feeding
If the machine isn’t feeding properly, check the following:
1. There is air pressure entering and leaving the PCU. Check the air pressure by
disconnecting the hose quick disconnects and checking for air bleed (Figure 2-
7 on page 21).
2. The emergency stop is reset (Section 5.3.3 on page 64 for PCU and
Section 2.3.2 on page 21 for HPU).
3. The feed is engaged (Figure 3-33 on page 48).
4. The air valve assembly is assembled correctly (Figure A-8 on page 88,
Figure A-19 on page 99, and Figure B-1 on page 111). Check that the 3/8" (9.5
mm) and 1/4" (6.4 mm) quick disconnects are connected to the correct hose
connections on the spindle cap.
5. The leadscrew is free to turn in the desired direction. On the end of the turning
arm, insert a 10-mm hex wrench to use as a crank handle and then turn it.
5.5.3 The feed is slow or unresponsive
If the feed is slow or unresponsive, the
most likely cause is dirty air filters on
the feed box.
Clean both filters at the same
time.
Do the following to clean the feed box
air filters:
1. Unscrew and remove the air fil-
ters on either end of the feed
box (Figure 5-3).
2. Clean the filters with solvent.
3. Blow out the filters with com-
pressed air.
4. Replace the filters in the feed box.
