Operation Each compressor is bench tested under load at the factory to ensure proper break-in and operation. While it is not necessary to follow any break-in procedure, the following checks should be made before putting the unit into service and periodically during use. Before Start-Up Inspect unit for any visible signs of damage. Check the oil level in the compressor with the dipstick on the unit. If oil is needed, use American Eagle synthetic compressor oil (P/N C0087) or an equivalent synthetic oil.
Maintenance The following table is a list of routine maintenance items, including service intervals. Service intervals are listed as hours, days, or weeks, whichever occurs first. American Eagle recommends that these service intervals be followed. Before performing any maintenance function “Lock Out” or “Tag Out” all sources of power. Be sure all air pressure in unit is relieved. Failure to do so may result in injury or equipment damage.
SRS-65 Oil Level The oil level in the oil receiver container is an important factor for the operational reliability of the system. Check Intervals: 1. Before starting unit. 2. Every 100 operating hours Check Procedures: 1. Switch off the unit with main power and prevent it from accidentally being turned on. 2. Allow one full minute to pass after stopping compressor. 3. Unscrew the cap of the inlet connection pipe with the oil receiver discharged. 4. Check the oil level with the dipstick. 5.
Changing the Oil WARNING You may change the unit oil only when the unit has been stopped and completely discharged. Note: Prior to changing the unit oil make sure the unit has an operating temperature 140-175°F (60-80°C). Maintenance Procedure: 1. Switch off the main power to the unit. 2. Slowly unscrew the oil fill cap. 3. Unscrew the oil drain plug carefully and place a container underneath. 4. Drain the oil from the separator receiver until oil stops draining out. Then replace the drain plug. 5.
Oil Filter The oil filter is located in front of the unit. Replace it after the first 50 hours of service. Then replace it every 1000 hours of service after that (or as soon as differential pressure is about 25 psig) Maintenance procedure: 1. Switch off the main power to the unit. Fully relieve the unit of pressure. 2. Slowly unscrew and remove the oil filter with an oil filter wrench. 3. Grease the new filter gasket. 4.

Installation COMPONENT INSTALLATION This section pertains to the installation of the air compressor, PTO, pump and other related items. The instructions are intended as a guide to assist you with particular installation. These instructions will provide only general information. Pump Assembly: The pump assembly may either be installed directly on the PTO or as an optional method, may be driven by a driveline from the PTO.

Component Installation Continued... PRESSURE LINE AIR DELIVERY RETURN LINE Hydraulic System: The hydraulic system consists of the pump, oil reservoir, filters and hoses. Installed on the compressor is a valve block assembly that controls the flow to the hydraulic motor. To this block, a 1/2” high-pressure hose must be attached. This hose comes from the hydraulic pumps pressure side. A 3/4” minimum low-pressure return line is connected to the oil cooler outlet and is routed to the oil reservoir.
Compressor Pressure Switch Kick Out (Step 1) Pressure Setting Adjustment Screw (145-150 psi) - + - + Kick On (Step 2) Pressure Setting Adjustment Screw (115-120 psi) Note: Turning adjustment screws clockwise increases psi settings. Turning adjustment screws counterclockwise decreased psi settings. Location inside box of SRS Compressors Pressure Setting Instructions: 1. Always set the kick out pressure setting first. 145 psi minimum/150 psi maximum. 2.

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. Solution Problem Possible Cause Compressor shuts down with air demand: Compressor temperature. Low oil level.
Problem Possible Cause Solution Compressor Stalls: Belt Slipping. Readjust and tighten. Insufficient hydraulic system pressure or flow. Check the following: 1. Setting on supply pressure system relief valve. 2. Ensure adequate pressure and flow. 3. Check and see if other hydraulic system’s activated off same hydraulic supply. *This can occur if another hydraulically activated component is used off the same pump system.
