5.4.2 SETTING THE MINIMUM PRESSURE
VALVE
Before performing maintenance:
Shut down machine, relieve all system
pressure and lock out all power, as per the
Safety Section of this manual.
NOTE THAT THE SYSTEM CAN BE
STARTED REMOTELY:
Always clearly tag the start-up
instrumentation against accidental system

2. Start the compressor and allow it to
been accumulate pressure build-up.
3. Using the electronic display as a guide,
adjust the grub screw [C] until minimum
pressure level is achieved.
4. Tighten the lock nut [D] to secure the
grub screw at the proper minimum
pressure level.

5.4.3 COMPRESSOR THERMAL VALVE

The thermal valve controls the hydraulic oil
temperature and permits for rapid hydraulic
oil warm up. The valve commences to pass a
portion of the oil through the cooler at 100°F
(37.8°C), and is fully open at 125°F (51.7°C).
The valve is preset, and cannot be adjusted.
If maintenance is required due to a faulty or
failing valve, the complete valve should be
replaced.
Department to obtain a replacement valve.
5.4.4 SERVICING THE SYSTEM CIRCUIT
BREAKER, FUSES AND RELAY
Consult Figure 5-3. for the locations of the
fuses
recommends using a fuse removal tool,
though pliers will suffice, when removing the
fuse.
Fuses will need to be replaced if blown
when tripped. When changing a fuse, or
dealing directly with any function of the
electrical system maintenance, always be
aware of the safety warnings given in

5.4.5 SAFETY SHUTDOWN SYSTEMS

Protection for over-pressure and/or over-
temperature is provided. If either condition
should occur, the diverter valve should
activate to divert hydraulic fluid back to the
tank and the compressor will stop. A screen
will appear on the control panel that will need
to be reset to run.
