INSTALLTION
1. Place press on rigid bench or table at a convenient height for operator. Bolt securely to the
bench.
2. Connect 100 P.S.I. filtered shop air supply (40 micron min) to 3/8 N.P.T. inlet port of air prep
assembly.
SET UP AND OPERATION
1. Loosen locknut and adjust pressure regulator until pressure gauge reads desired pressure
(100 P.S.I.).
CAUTION : Do not operate at pressure greater than 125 P.S.I.
2. Adjust speed control valve to slow position by turning valve stem clockwise (or in).
3. Check to make sure safety sleeve assembly is in the correct position on the press before
operating
4. Keeping hands clear of shaft, actuate press by depressing palm buttons.
5. Release palm buttons. Shaft should return to fully retracted position (2 pos. circuit) or stop
movement (3 pos. circuit)
6. Remove safety sleeve from press.
7. Loosen locking nut and adjust stop nut to obtain desired stroke. Distance between bottom
of the stop nut and top surface of stop cap or frame is the stroke of the shaft.
CAUTION: Do
not back off locking nut beyond top of threaded shaft. Doing so may damage packings.
8. Replace safety sleeve and re-actuate press.
9. If necessary, re-adjust stop nut, speed control and pressure regulator to obtain desired
setting. CAUTION: Never operate press unless safety sleeve is in place and hands are clear
of shaft.
10. Install tooling into hole provided in shaft, securing with set screw.
11. Install dies, nests or anvils onto base using tapped holes provided.
12. Make any final stroke, speed and pressure adjustments to obtain desired workpiece
configuration with tooling in place.
MAINTENANCE
LUBRICATION
Air presses are lubricated at the factory and should require no additional lubrication. However, if a
press is disassembled for service or replacement of parts, all internal surfaces should be coated with a
light bearing grease such as Lubriko M6 (Master Chemical Co.) or equivalent.
CUSHION ADJUSTMENT
Model AP 1900D employs an external cushion spring for the return stroke. The cushion is preset at the
factory and should require no further attention. However, if the machine should begin to “hammer”
during the return stroke, cushion adjustment may be necessary, as follows:
1. Remove safety sleeve from press
2. Loosen cushion adjustment locking nut.
