Tank Pressure Gauge; Installation - Porter-Cable US58 Instruction Manual

cut-out pressure.
sAfETy vALvE
If the pressure switch does not shut off the air
compressor at its cut-out pressure setting, the
safety valve (F) will protect against high pres-
sure by popping out at its factory set pressure
(slightly higher than the pressure switch cut-out
setting).
CHECk vALvE
When the air compressor is operating, the check valve 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.

TAnk prEssUrE GAUGE

The tank pressure gauge (B) indicates
the reserve air pressure in the tank.
OUTLET prEssUrE GAUGE
The outlet pressure gauge (C) indi-
cates the air pressure available at the
outlet side of the regulator. This pres-
sure is controlled by the regulator and
is always less than or equal to the tank pressure.
rEGULATOr
The regulator (D) controls the air pressure shown on the outlet
pressure gauge. Turn regulator knob clockwise to increase pres-
sure and counterclockwise to decrease pressure.
UnIvErsAL QUICk COnnECT BODy
The universal Quick Connect body (E) accepts the three most
popular styles of Quick Connect plugs: Industrial, automotive, and
ARO.
DrAIn vALvE
The drain valve (G) is located at the base of the air
tank and is used to drain condensation at the end of
each use. See Draining Air Tank under Maintenance.
COOLInG sysTEM
This compressor contains an advanced design cooling system.
It is normal for this fan to blow air through the vent holes in large
F
amounts. The cooling system is working when air is expelled.
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.
MOTOr OvErLOAD prOTECTOr
The motor has an automatic reset thermal overload protector. If the
D
C
B
E
motor overheats for any reason, the overload protector will shut off
the motor. The motor must be allowed to cool down before restart-
ing. The compressor will automatically restart after the motor cools.
