a. Have your regulator serviced by a
qualified repair person using only identical
replacement parts. This will ensure that
the safety of the regulator is maintained.
Air Regulator Safety Warnings
1. Risk of bursting - do not adjust regulator higher
than marked maximum pressure of attachment.
2. Risk of injury - do not direct air
stream at people or animals.
3. Do not use to supply breathing air.
4. Keep regulator well-ventilated.
Do not cover regulator during use.
5. Drain Air Filter daily and after use.
Internal rust causes tank failure and explosion.
6. Do not remove the valve cover or
adjust internal components.
7. Do not use the air hose to move the regulator.
8. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.
9. All air line components, including hoses, pipe,
connectors, filters, etc., must be rated for a minimum
working pressure of 160 PSI, or 150% of the
maximum system pressure, whichever is greater.
10. Industrial applications must follow OSHA guidelines.
11. Maintain labels and nameplates on the
regulator. These carry important safety
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
12. This product is not a toy.
Keep it out of reach of children.
13. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
14. WARNING: The brass components of this product
contain lead, a chemical known to the State
of California to cause cancer and birth defects
or other reproductive harm. (California Health
& Safety Code § 25249.5, et seq.)
15. WARNING: This product contains di (2-ethylhexyl)

Installation
3B 1C
Figure A
1. Thread the Regulator Handle into the Air Regulator
only a couple of turns. Do not tighten it.
Tightening it will set the regulator to high
pressure, possibly causing property damage
when first connecting the air supply.
2. Incorporate an in-line shutoff valve, and
quick coupler for best service, as shown on
Figure B on page 6 and Figure C on page 7.
An in-line shutoff ball valve is an important
safety device because it controls the air
supply even if the air hose is ruptured.
The shutoff valve should be a ball valve
because it can be closed quickly.
Note: Wrap all threaded connectors before
connecting them with pipe thread seal
tape (PTFE) to prevent leaking.
3. Attach an air hose to the compressor’s air outlet.
Connect the air hose to the air inlet of the unit.
Note: Air flow, and therefore tool performance,
can be hindered by undersized air supply components.
The air hose must be long enough to reach
the work area with enough extra length to
allow free movement while working.
4. Check that the regulator handle is loose.
5. Close the in-line shutoff valve between
the compressor and the tool.
6. Turn on the air compressor according to
the manufacturer’s directions and allow it
to build up pressure until it cycles off.
7. Inspect the air connections for leaks.
Repair any leaks found.
Air Connection Setup
1. Connect the regulator valve, an inline shut off
valve and a 1/4″ NPT air hose to the Compressor’s
Quick Coupler. The air hose must be long
enough to reach the work area with enough extra
length to allow free movement while working.
Note: An in-line shutoff ball valve is an important
safety device because it controls the air supply even
if the air hose is ruptured. The shutoff valve should
be a ball valve because it can be closed quickly.
2. Depending on the tool that will be used
with this regulator, incorporate additional
components, such as an in-line oiler, a filter,
or a dryer (all sold separately), as shown on
Figure B on page 6 and Figure C on page 7.
Consult air tool’s manual for needed accessories.

Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this
manual including all text under subheadings therein before set up or use of this product.
Regulator Area Set Up
1. Designate a work area that is clean and well-lit.
The work area must not allow access by
children or pets to prevent injury.
2. Locate the Regulator on a flat level surface to
ensure proper pump lubrication and to prevent
damage to the unit. Keep at least 12″ of space
around the unit to allow air circulation.
3. Route the power cord from the regulator to
the grounded wall outlet, along a safe path
without creating a tripping hazard or exposing
the power cord to possible damage.
General Operation
Note: At the beginning of the day’s first use of the
Air Regulator, check for air leaks by applying soapy
water to connections while the Air Regulator is pumping
and after pressure cut-out. Look for air bubbles. If air
bubbles are present at connections, tighten connections.
Do not use the Air Regulator unless all connections are
air tight, the extra air leaking out will cause the regulator
to operate too often, increasing wear on the regulator.
WARNING! TO PREVENT SERIOUS
INJURY AND DEATH FROM
EXPLOSION:
Do not exceed 160 PSI
1. Adjust the Regulator Knob (1C) so that the
air output is enough to properly power the
tool, but the output will not exceed the tool’s
maximum air pressure at any time. Turn the
knob clockwise to increase the pressure and
counter-clockwise to decrease pressure. Adjust
the pressure gradually, while checking the
air output gauge (6B) to set the pressure.
2. Make sure the air tool’s throttle or switch is in the
off position. Connect the air tool to the air hose.
3. Open the in-line Shutoff Valve.
4. Use the air tool as needed.
5. After the job is complete, turn the
compressor’s Power Switch OFF.
6. Disconnect the Air Regulator.
7. Close the in-line Shutoff Valve.
8. Bleed air from the tool then disconnect the tool.
9. Drain the Air Filter/Regulator of water daily. With the
unit under pressure, open the Drain Plug (14A) to
expel any accumulated moisture from the Air Filter.
10. Clean, then store the Air Regulator indoors.
Maintenance and Servicing
Procedures not specifically explained in this manual must
be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Turn the Power Switch “OFF” and unplug the Regulator from its electrical outlet
before performing any inspection, maintenance, or cleaning procedures.
TO PREVENT SERIOUS INJURY FROM REGULATOR FAILURE:
Do not use damaged equipment. If abnormal noise or vibration occurs,
have the problem corrected before further use.

SAFETYOPERATIONMAINTENANCE INSTALLATION
Cleaning, Maintenance, and Lubrication
1. BEFORE EACH USE, inspect the general
condition of the air regulator. Check for:
• loose hardware,
• misalignment or binding of moving parts,
• cracked or broken parts,
• damaged electrical wiring, and
• any other condition that may
affect its safe operation.
2. AFTER USE, wipe external surfaces of
the regulator with a clean cloth.
3. WARNING! If the supply cord of this
regulator is damaged, it must be replaced
only by a qualified service technician.
Maintenance Schedule
Following are general guidelines for maintenance checks of the Air Regulator.
Note: The environment in which the regulator is used, and the frequency of use will affect how often
you will need to check the Air Regulator components and perform maintenance procedures.
Daily:
a. Make sure all nuts and bolts are tight.
b. Drain moisture from air tank.
c. Check for abnormal noise or vibration.
d. Check for air leaks.*
e. Wipe off any oil or dirt from the regulator.**
* To check for air leaks, apply soapy water to joints while
the Air Regulator is pressurized. Look for air bubbles.
** To clean the regulator surface, wipe with
a damp cloth, using a mild detergent or mild solvent.
Weekly:
a. Inspect Air Filter.
Quarterly (every 3 months):
a. Tool Disassembly, Cleaning, and Inspection:
Have the internal mechanism cleaned, inspected,
and lubricated by a qualified technician.
Air Filter Maintenance
Check the Air Filter weekly to see if it needs replacement.
Replace the filter more often if regulator is used in dirty environments.
3. Periodically remove the Filter (6A), rinse
it out with water and put it back in.
4. To access the air filter:
a. Secure the Top Nut (1A) in a vise.
b. Loosen and remove the Bottom Nut (13A).
c. Pull off the Housing (7A), exposing
the Filter Assembly.
d. Disassemble the Filter Assembly. Keep track of
assembly order. (Housing is not shown.)
See Figure D.
5. Remove the Filter.
6. Check that the Large Plate and Cup are in
place, and replace with a new Filter.
7. Reassemble Filter Assembly according to
assembly order described in Figure D.
Note: Retaining Ring should slide on tightly
against the Filter Washer and Filter. If it
is loose, the Filter will not function.
8. Replace the Housing.
Note: Rubber Seals on Nuts and Housing must
be in good condition before reassembly.
9. Thread Bottom Nut back on to Stud. Tighten.
