Portable Air Compressor
13- ENG
Westward Operating Instructions and Parts Manual
Model 4YD76A
HOW TO START
1.
Turn the On/Auto/Off lever to
“AUTO” and allow tank pressure
to build. Motor will stop when
tank pressure reaches “cut-out”
pressure.
2.
Pull the regulator knob out and
turn clockwise to increase
pressure. When the desired
pressure is reached push knob in
to lock in place. The compressor
is ready for use.
NOTE:
Always operate the air
compressor in well-ventilated areas
free of gasoline or other combustible
vapors. If the compressor is being
used to operate a sprayer DO NOT
place near the spray area.

Check Safety Valve

NOTE:
See “Operation” section for
the location of controls.
Unit cycles
automatically when
power is on. When performing
maintenance, you may be exposed
to voltage sources, compressed
air, or moving parts. Personal
injuries can occur. Before
performing any maintenance or
repair, disconnect power source
from the compressor and bleed off
all air pressure.
TO CHECK SAFETY VALVE
If the safety valve
does not work
properly, over-pressurization may
occur, causing air tank rupture or
an explosion.
1.
Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. If the valve is
stuck or does not operate
smoothly, it must be replaced
with the same type of valve.
TO DRAIN TANK
1.
Set the On/Auto/Off lever to
“OFF”.
2.
Pull the regulator knob out and
turn clockwise to set the outlet
pressure to zero.
3.
Remove the air tool or accessory.
4.
Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately 20
psi. Release safety valve ring.
5.
Drain water from air tank by
opening drain valve (counter-
clockwise) on bottom of tank.
Water will
condense in the air
tank. If not drained, water will
corrode and weaken the air tank
causing a risk of air tank rupture.
6.
After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.
NOTE
: If drain valve is plugged in,
release all air pressure. The valve
can then be removed, cleaned, and
reinstalled.
