Manual Lock: The manual lock allows you to manually unload the
compressor with air pressure in the tank. To operate the unloading
device in the head, rotate the flip lever to an in-line position (dashed
lines). Be sure to return lever to the loaded position after starting the
engine or the pump will not operate at preset pressures.
SAFETY RELIEF VALVE
This valve (A) is designed to prevent system failures
by relieving pressure from the system when the
compressed air reaches a predetermined level. The
valve is preset by the manufacturer and must not be
removed or modified in any way.
AIR INTAKE FILTER(S)
The filter(s) (B) are designed to clean air entering the
pump. To ensure the pump continually receives a clean,
cool, and dry air supply the filter(s) must always be
clean and the filter intake must be free from
obstructions.
AIR TANK DRAIN VALVE(S)
The drain valve(s) (C) are used to remove
moisture from the air tank after the air
compressor is shutoff.
TANK PRESSURE GAUGE
The tank pressure gauge (D) indicates air
pressure in the air tank.
REGULATED PRESSURE GAUGE
The regulated pressure gauge (E) indicates the
air pressure available at the outlet side of the
regulator. This pressure is controlled by the
regulator and is always less or equal to the air
tank pressure.
PRESSURE REGULATOR
The regulator knob (F) controls the air pressure
coming from the air tank.
PILOT VALVE CUT-OUT PRESSURE ADJUSTMENT
NOTE: Unit can remain running while performing this adjustment
WARNING : Aftercooler, pump head, and surrounding parts are
very hot; do not touch. (see the Hot Surfaces identified on page 2)
WARNING - Moving Parts: Keep your hair, clothing and gloves
away from moving parts. Loose clothing, jewelry, or long hair can be
caught in moving parts. Air vents may cover moving parts and should
be avoided as well. Do not remove the protective covers from this
product.
WARNING : The pilot valve is brass which is a soft metal. Do not
overtighten screw as threads can strip out.
1. Hold “I” firmly and loosen nut “H”.
WARNING : Do not loosen screw “G” more than 1 revolution as
screw is subjected to tank pressure and can burst out which can harm
the user or surrounding personnel.
2. Turn screw “G” clockwise to
increase cut-out pressure limit or
counter clockwise to decrease
cut-out pressure. (example: if the
cut-out pressure on the tank
gauge reads 120 psi. and desired
cut out is 130 psi, turn screw “G” clockwise)
3. Drain air from tanks through drain valves until pump begins to
charge tanks.
4. Close drain valves.
5. Monitor cut-out pressure to verify the new setting
6. Once setting is complete hold screw “G” firmly
7. Hold “G” firmly and tighten nut “H”
PILOT VALVE PRESSURE DIFFERENTIAL ADJUSTMENT
NOTE: Unit can remain running while performing this adjustment
