Air Filter/Regulator Safety Warnings

1. Risk of bursting – do not adjust Filter/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 Filter/Regulator well-ventilated. Do not cover Filter/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 Filter/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 200 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 Filter/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.

Installation

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.

Note:

• For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram near the end of this manual.
• This air tool may be shipped with protective plugs covering the air ports. Remove these plugs before set up.
  

TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

Functions

1. Thread the Regulator Handle into the Filter/Regulator only a couple of turns. Do not tighten it. Tightening it will set the Filter/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 A on page 6 and Figure B 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. 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.

4. Close the in-line shutoff valve between the compressor and the tool.

5.  Turn on the air compressor according to the manufacturer’s directions and allow it to build up pressure until it cycles off.

6.  Inspect the air connections for leaks. Repair any leaks found.

Air Connection Setup

1. Connect the Filter/Regulator, an in line shut off valve and a 1/4″ NPT air hose to the Compressor’s Quick Coupler as outlined in Step #3 of Installation. Next, add an air hose from the outlet of the Filter/Regulator to the air tool in the work area. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.
2. Depending on the tool that will be used with this Filter/Regulator, incorporate additional components, such as an in-line oiler, a filter, or a dryer
   (all sold separately), as shown on Figure A on page 6 and Figure B on page 7. Consult air tool’s manual for needed accessories.

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.

Filter/Regulator Area Set Up

Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent injury.
General Operation

Note: At the beginning of the day’s first use of the Filter/Regulator, check for air leaks by applying soapy water to connections while the Filter/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 Filter/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 200 PSI

1. Adjust the Regulator Handle 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 to set the pressure.
2. Connector air hose to tool’s Air Outlet.
3. Make sure the air tool’s throttle or switch is in the off position. Connect the air tool to the air hose.
4. Open the in-line Shutoff Valve.
5. Use the air tool as needed.
6. After the job is complete, turn the compressor’s Power Switch OFF.
7. Disconnect the Filter/Regulator.
8. Close the in-line Shutoff Valve.
9. Bleed air from the tool then disconnect the tool.
10. Drain the Filter/Regulator of water daily. With the unit under pressure, open the Drain Plug to expel any accumulated moisture from the Air Filter.
11. Clean, then store the Filter/Regulator indoors.
