Portable Air Compressor
11- ENG
Westward Operating Instructions and Parts Manual
Model 4YD76B
Safety Valve:
If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its
factory set pressure (slightly higher
than the pressure switch "cut-out"
setting).
Outlet Pressure Gauge:
The outlet
pressure gauge indicates the air
pressure available at the outlet side of
the regulator. This pressure is
controlled by the regulator and is
always less than or equal to the tank
pressure.
Tank Pressure Gauge:
The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator:
Controls the air pressure
shown on the outlet pressure gauge.
Turn the knob clockwise to increase
pressure and counterclockwise to
decrease pressure.
Drain Valve:
The drain valve is
located at the base of the air tank and
is used to drain condensation at the
end of each use.
Cooling System (not shown)
: This
compressor contains an advanced
design cooling system. At the heart of
this cooling system is an engineered
fan. It is perfectly normal for this fan
to blow air through the vent holes in
large amounts. You know that the
cooling system is working when air is
being expelled.
