IMPORTANT: Read and follow all Instructions and Safety
Precautions before installing, operating or maintaining this
equipment. Keep this manual for future reference.
Improper use can cause bodily injury or equipment
damage. Read the following:
• This air regulator and gauge assembly is intended only
for use in general service air systems. Do not use for
liquids or gases other than air.
• Do not use where pressure or temperature can exceed
rated operating conditions (see specifications).
• Regulated outlet pressure must never be set higher
than the maximum operating pressure of the down-
stream air tool or equipment. An outlet pressure gauge
should always be used.
The accuracy of the indication of pressure gauges can
change during shipment and normal use. If gauge
accuracy is necessary for preventing risks of injury or
property damage, the gauge should be checked before
use and on a routine periodic basis. (See ANSI B40-1974
for gauge standards.)

DESCRIPTION
This unit is used in a compressed air system to maintain a nearly
constant outlet pressure despite change in inlet air pressure and
changes in downstream flow requirements. It is also used for
finer control of air at the spray device. The air setting can be
locked in place by pushing the adjusting knob downward.

SERVICE MANUAL
HARG-510 AIR REGULATOR
AND GAUGE ASSEMBLY

INSTALLATION
1. Install regulator as close as possible to the device being
serviced. Regulator can be installed at any angle.
2. In systems with a cyclic demand, install regulator upstream
of cycling control valves.
3. Air line piping should be same size as regulator ports.
4. Air flow must be in same direction as arrow on bottom of
regulator body.
OPERATION
1. Before turning on system air pressure, turn adjusting knob full
counterclockwise. This will close regulator to produce zero
air pressure. The knob is locked in position when pushed
downward towards the regulator body.
2. Turn on system air pressure.
3. Turn regulator adjusting knob clockwise until desired outlet
pressure is reached.
4. To avoid minor readjustment after making a change in pres-
sure setting, always approach the desired pressure from a
lower pressure. When reducing from a higher to a lower
setting, first reduce to some pressure less than that desired,
then bring up to the desired point. Lock the pressure setting
by pushing the knob downward.
PREVENTATIVE MAINTENANCE
Risk of injury from pressurized components. Turn off
inlet air pressure and bleed off remaining pressure
before disassembly.
1. Turn regulator knob counterclockwise until it stops.
2. Unscrew the bonnet from the regulator body, remove adjusting
screw and nut, then the regulating spring (4), slip ring (5)
and diaphragm (6). Using a screwdriver, unscrew the
valve seat (7) and o-ring (8). Then remove valve (9) and valve
spring (10).

CLEANING
Do not submerge regulator in spray gun solvents or use
solvents to clean regulator parts. Damage may occur to
gauge or regulator components.
1. Clean parts using warm water and soap.
2. Inspect all parts and replace any damaged ones.
Reassembly:
1. At reassembly, apply a small amount of lubricant SSL-10 gun
lube to adjusting screw threads inside bonnet.
2. Torque valve seat (7) to 4-6 in./lbs. (do not overtighten).
Torque bonnet to 50-60 in./lbs.
