Rotate the manual lock unloader lever to the
open position to prevent air tank pressure
buildup. Rotate manual lock unloader lever to
the closed position after starting the engine
to allow air tank pressure to build. note: Air
will not build in tank when manual lock
unloader lever in the open position.
sAfety VAlVe
This valve (I) is designed to prevent system failures
by relieving pressure from the system when the
compressed air reaches a predeter mined level. The
valve is preset by the manu facturer and must not be
removed or modified in any way.
AIr IntAke fIlter
The filter (A) is designed to clean air entering the 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 VAlVes
The drain valve (J) is used to remove
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 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.
CLOSED
OPEN
to Adjust regulator:
1. Pull regulator knob (F) out to unlock.
2. Turn knob clockwise to increase regulated pressure and
counterclockwise to decrease regulated pressure.
3. When desired pressure is shown on the regulated pressure
I
gauge push knob in to lock.
WARNING: Risk of Bursting. Too much air pressure causes a
hazardous risk of bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The regulator outlet
A pressure must never exceed the maximum pressure rating.
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 sensors
J
The air compressor engine is equipped with low oil shutdown
sensors. These are safety devices designed to protect your engine
from damage in the event the oil level in the crankcase is below
E
minimum.
D
If the oil in 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.
