4.0 BASIC OPERTION AND FUNCTION
1. Locate and remove the shipping plug and discard. Ensure the oil level is just below (approx. 1/2”) the oil filler plug hole.Install the vent / oil fill /
dip stick plug.
2. Remove air inlet shipping plug and discard. Pour a teaspoon of good quality, air tool #10 wt. non-detergent oil into the air inlet port). Install the
appropriate air supply coupler and a 3/8” NPT hydraulic connection. The air quick disconnect configuration of your choice can be installed in the
threaded hole underneath the foot pedal labeled “PUMP”. An in-line filter/ regulator/lubricator should be installed close to pump. Add a few drops
of SAE 10 oil to the air intake weekly if no lubricator is used or when pump will be idle for a long time.
3. Remove the pressure port shipping plug and discard. Use at least 1-1/2 wraps of Teflon tape (or suitable sealant) on the hose fitting threads.
Make sure the first complete thread is free from tape or sealant so they do not enter and contaminate the hydraulic system. Thread the hose fit
ting into the pump manifold’s threaded hole and turn until snug - make sure the hose fitting threads are not cross-threaded.
4.1 OPERATION
1. Make sure the pump is on a level surface.
2. Connect Foot Pump to an external air source that is capable of supplying 90 PSI @ 10 CFM. Next connect a 3/8” NPT quick disconnect coupler
or hose to the oil outlet side. (SIMPLEX recommends that a gauge adaptor and 10,000 PSI gauge be use during operation). Connect tooling (I.e.
cylinder, bender, or cutter)
3. Check for leaks in system and repair as needed. Before repairs are made, disconnect air source and application, then depressurize reservoir. Do
so simply by pressing the pedal or pendant button for three seconds (see figure 1).
4. To build pressure, depress the pedal or pendant button where “PUMP” is located. Operate pump until desired
position is reached and/orpressure is obtained (see figure 1).
5. To retract application, simply press down on the RELEASE valve or pendant button portion of the pump. Fully
depressing pedal will LOCK the DETENT feature to “on” (see figure 1).
4.2 AFTER COMPLETING THE JOB
Before disconnecting hoses, fittings, etc., be sure the ram is unloaded and retracted, then disconnect air source and hydraulic connections. Store
the pump in a clean, dry area.
5.0 PERIODIC MAINTENANCE
A) MAINTENANCE
1. Inspect hose and connections daily. Replace damaged components immediately with Simplex Authorized replacement parts only.
2. Tighten connections as needed. Use pipe thread Teflon when servicing connections.
NOTE: DO NOT OVER TIGHTEN CONNECTIONS
.
3. When Not In Use Or During Storage:
• Disconnect pump from air source, depressurize and disconnect hydraulic hoses from application.
• Wipe clean, throughout.
• Shelter the pump with protective cover.
• Store in clean, dry environment.
• Avoid temperature extremes.
B) HOW TO FILL THE RESERVOIR
1. Disconnect hydraulic hose from application, remove air source from pump.
2. With reservoir horizontal, remove the vent / oil filler plug.
3. Use a small funnel to fill reservoir so the oil level remains the distance stated below in the table, distances are measures from the top of the fill
hole.
