3. Ensure that drain valve is closed in the vertical
position (A).
4. Ensure that the safety valve (B) is functioning
properly by pulling on the valve ring and allow
the valve to reset. The safety release valve is
designed to protect against high pressure air
from the air tank when its factory set pressure
(slightly higher than the pressure switch cut-out
setting) is exceeded.
If the safety release valve vents

attempting maintenance.
ADjuSTING REGuLATOR
This compressor is provided with an internal reg-
ulator that controls the output pressure of two
female quick connect couplers. Regulated pres-
sure will be equal to or less than tank pressure
depending on user setting.
To adjust regulated pressure:
1. Pull regulator knob out (A).
2. To increase pressure, turn clockwise.
3. To decrease pressure, turn counter clockwise.
4. When desired pressure is set, push regulator
knob in to lock pressure.
5. Regulated pressure gauge is displayed as (B).
