SHD-60AF Manual

Troubleshooting

If symptoms of poor performance develop, the following chart can be used as a guide to investigate

and correct the problem. When diagnosing faults in operations of the air compressor, always check

that the hydraulic power source is supplying the correct hydraulic flow and pressure that is listed in

the compressor specification section of this manual. Note: To Operate, the American Eagle SHD-

60AF Compressor needs 10 GPM and 1800 PSI System Pressure.

Problem

Compressor locks up at 110

psi and higher while under

load:

Note: When checking

hydraulic pump flow,

make sure the air tank is

closed and the

compressor is running.

Compressor will not

operate:

Possible Cause

Weak Hydraulic Motor.

Faulty Hydraulic Pump.

Oil Pressure is low.

Air receiver is full.

12 Volt power is not going to the line

side of the pressure switch.

Faulty Pressure Switch.

Hydraulic Lines not installed correctly.

Air Couplers or hoses are blocked.

Inline Check-Valve is leaking.

Faulty Solenoid V

alve.

Compressor is locked up.

Hydraulic motor malfunctioning.

Hydraulic pump malfunctioning.

Solution

If the Hydraulic pump is supplying the

recommended amount of fluid to the hydraulic

motor, replace the hydraulic motor.

If the pump pressure is below the

recommended GPM, replace the Hydraulic

pump if necessary.

If the oil pressure gauge is reading in the red

area, the oil pressure is low. See the Low Oil

Pressure entry in this troubleshooting section.

Drain and activate pressure switch.

If there is no power going to the line side of the

pressure switch, trace the wire back to the

power source.

If there is no power going to the solenoid valve,

replace the pressure switch.

Reinstall hydraulic lines.

Locate and remove restriction.

Disassemble, clean, and reinstall or replace.

If there is power going to the pressure switch,

press down on the solenoid valve bypass

button. If the compressor starts to operate,

replace the solenoid valve.

Remove the coupler and lovejoy between the

compressor pump and the hydraulic motor.

urn the compressor over by hand. If the

compressor turns over freely, the pump is ok.

This indicates there is a possible hydraulic

problem.

Inspect and repair.

Check flow and pressure settings.
