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 TANK PRESSURE GAUGE
The air tank pressure gauge (D) indicates air pressure in the air tank.
REGULATED PRESSURE GAUGES
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.
REGULATORS
The regulator knob (F) controls the air pressure coming from the
air tank.

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 pressure must never exceed the maximum pressure
rating.
