145PSI(±5%).Duringinationoftirepressuresbetween115PSIto145PSI,ifyoustopination,
the compressor may not restart. This is completely normal, since inline pressure is greater than
cut-on pressure of the pressure switch and less than cut-off pressure of the pressure switch.

USER MANUAL
OPERATING INSTRUCTIONS (cont’d):
This air compressor comes with 1/4” quick connect stud. An extension coil hose and a tire
ination gun are also included with your compressor. Each end of the extension coil hose is
equipped with a 1/4” quick connect coupler. The tire ination gun comes with a 1/4” quick
connect stud, pressure gauge, rubber hose, bleeder valve and tire chuck. Attach one end of
the extension coil hose to the stud on your compressor and the other end to the stud on the
tire gun kit. The tire gun kit can be used for both airing up and airing down. Please familiarize
yourself with the following functions of this versatile air tool:
