AIR INTAKE FILTER
The filter (A) is designed to clean air entering the pump.
A
To ensure the pump continually receives a clean, cool,
and dry air supply the filter must always be clean and
the filter intake must be free from obstructions.
AIR TANK DRAIN VALVE
The drain valve (J) is used to remove
J
moisture from the air tank after the air
compressor is shut off.
AIR TANK PRESSURE GAUGE
The air tank pressure gauge (D) indicates air pressure in the air tank.
REGULATED PRESSURE GAUGE
The regulated pressure gauge (E) indicates the
F
D
E
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.
REGULATOR
The regulator knob (F) controls the air pressure coming from the air
tank.
To Adjust Regulator:
1. Pull regulator knob (F) out.
2. Turn knob clockwise to increase regulated pressure and counter-
clockwise to decrease regulated pressure.
3. When desired pressure is shown on the regulated pressure
gauge push knob in to lock.
THROTTLE CONTROL
When maxi mum air tank pres sure is reached and the unloader valve
vents air, it activates the throttle control on the engine. This gas
saving feature holds the engine at a factory-set idling speed until air
pressure in the air tank drops to reset pressure. The unloader valve
then reactivates the throttle control and accelerates the engine to
full throttle.
LOW OIL SHUT DOWN SENSOR
The air compressor engine is equipped with a low oil shutdown
sensor. This is a safety device designed to protect your engine
from damage in the event the oil level in the crankcase is below
minimum.
If the oil in the engine gets low while the air compressor is running it
will automatically shut down the engine and will not restart until oil is
added to the engine. If the oil is low before start-up, the engine will
not start until oil is added.
NOTE: The low oil shutdown sensor is very sensitive. You must fill
the engine to the full mark on the dipstick to inactivate this safety
device.

INSTALLING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
when installing or disconnecting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 psi.
2. Apply sealant tape to hose threads.
3. Assemble hose to air outlet (G). IMPORTANT: Do not assemble
splitters directly to the air outlet (G).
NOTE: Assembling quick connect bodies to air outlet (G) and quick
connect plugs to hose ends make connecting and disconnecting
hoses simple and easy. Quick connect bodies and plugs are available
for purchase from your local dealer or authorized service center.
