mined level. The valve is preset by the manu facturer and must not be
removed or modified in any way.
CHECK VALVE
When the air compressor is operating, the
O
check valve (O) is open, allowing compressed
air to enter the air tank. When the air
compressor reaches cut-out pressure, the
check valve closes, allowing air pressure to
remain inside the air tank.
AIR INTAKE FILTER
The filter (A) is designed to clean air entering the
A
pump. 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 (H) is located at the base of
H
the air tank and is used to drain
condensation at the end of each use. See
Draining Air Tank under
Maintenance
.
TANK PRESSURE GAUGE
The tank pressure gauge (D) indicates the
D
reserve air pressure in the tank.
GLOBE VALVE/AIR DISCHARGE VALVE:
(sold separately, not shown)
Opens and closes air distribution from compressor.
REGULATOR
(sold separately, not shown)
:
An air pressure regulator or a separate air transformer which
combines the functions of air regulation and/or moisture and dirt
removal is recommended for most applications.
AIR COMPRESSOR PUMP
The pump compresses air into the air tank. Working air is not available
until the compressor has raised the air tank pressure above that
required at the air outlet.
GASOLINE ENGINE
The gasoline engine powers the pump. The engine drives a pulley
and belt, which transfers power from the engine to the pump
pistons via a flywheel and a crankshaft. The flywheel fan helps cool
the pump.
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.
