OPERATION Section 4 - Pg 02
4.2 Purpose of Controls (Continued)
Maintains the minimum of 65 psig in the
compressor sump. This valve restricts receiver
air discharge from receiver/sump when
pressure falls to 65 psig, however, full flow is
allowed at normal operating pressures.
Opens sump pressure to the atmosphere should
pressure inside the sump exceed 175 psig.
Opens a pressure line between the sump and
inlet valve allowing the inlet valve to regulate
air delivery according to air demand.
Vents sump pressure to the atmosphere at
shutdown.
4.3 Initial and Routine Start-Up Procedures
The following procedure should be used to make the initial start-up of your compressor:
1. Position the compressor on a level surface so that proper amounts of liquid can be
added if necessary.
2. Fill compressor fluid sump with fluid as recommended in Section 3, Specifications.
System capacity is 3-1/2 gallons.
3. Check engine oil level and add if necessary.
4. Start truck engine (let engine warm up).
5. Engage hydraulic system.
6. Bring up engine speed to proper RPM.
7. After the initial run, shut the compressor down and refill compressor with oil and
tighten any loose fittings.
For routine start-up of compressor system repeat steps #3 through #6.
