Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to

reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in damp or wet

locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically

powered tools in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let

them handle machines, tools, or extension cords.

4. Store idle equipment. When not in use, tools must be stored in a dry location to

inhibit rust. Always lock up tools and keep out of reach of children.

5. Do not force tool. It will do the job better and more safely at the rate for which it was

intended. Do not use inappropriate attachments in an attempt to exceed the tool

capacity.

Page 3SKU 46168

6. Use the right tool for the job. Do not attempt to force a small tool or attachment to

do the work of a larger industrial tool.There are certain applications for which this tool

was designed. Do not modify this tool and do not use this tool for a purpose for which

it was not intended.

7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in

moving parts. Protective, electrically non-conductive clothes and non-skid footwear

are recommended when working. Wear restrictive hair covering to contain long hair.

8. Use eye and ear protection. Always wear ANSI approved impact safety goggles.

Wear a full face shield if you are producing metal filings or wood chips.Wear an ANSI

approved dust mask or respirator when working around metal, wood, and chemical

dusts and mists.

9. Do not overreach. Keep proper footing and balance at all times. Do not reach over

or across running machines.

10. Maintain tools with care. Keep tools sharp and clean for better and safer

performance. Follow instructions for lubricating and changing accessories. Inspect

tool cords periodically and, if damaged, have them repaired by an authorized

technician.The handles must be kept clean, dry, and free from oil and grease at all

times.

11. Disconnect power.Unplug tool when not in use.

12. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches

are removed from the tool or machine work surface before plugging it in.

13. Avoid unintentional starting. Be sure the switch is in the Off position when not in

use and before plugging in.

14. Stay alert. Watch what you are doing, use common sense.Do not operate any tool

when you are tired.

15. Check for damaged parts. Before using any tool, any part that appears damaged

should be carefully checked to determine that it will operate properly and perform its

intended function. Check for alignment and binding of moving parts; any broken parts

or mounting fixtures; and any other condition that may affect proper operation. Any

part that is damaged should be properly repaired or replaced by a qualified

technician. Do not use the tool if any switch does not turn On and Off properly.

16. Guard against electric shock. Prevent body contact with grounded surfaces such

as pipes, radiators, ranges, and refrigerator enclosures.

17. Replacement parts and accessories. When servicing, use only identical

replacement parts.Use of any other parts will void the warranty. Only use accessories

intended for use with this tool. Approved accessories are available from Harbor

Freight Tools.

18. Do not operate tool if under the influence of alcohol or drugs. Read warning

labels on prescriptions to determine if your judgment or reflexes are impaired while

taking drugs. If there is any doubt, do not operate the tool.

Page 4SKU 46168

19. Use proper size and type extension cord. If an extension cord is required, it must

be of the proper size and type to supply the correct current to the tool without heating

up. Otherwise, the extension cord could melt and catch fire, or cause electrical

damage to the tool.This tool requires use of an extension cord of 0 to 20 amps

capability (up to 50 feet), with wire size rated at 12 AWG. Longer extension cords

require larger size wire. If you are using the tool outdoors, use an extension cord rated

for outdoor use.(signified by “WA” on the jacket).

21. Maintenance. For your safety, service and maintenance should be performed

regularly by a qualified technician.

22. Drain compressor every day. Do not allow moisture to build up inside the

compressor. Do not allow compressor to sit pressurized for longer than one hour.

23. Make sure all equipment is rated to the appropriate capacity. Do not use any air

tool that does not operate at 115 PSI.

24. Avoid explosions and fire. Never place flammable objects near the compressor.

Never spray water or any flammable liquids towards the compressor.

25. Avoid body injury. Never direct the air outlet at persons or animals.

Note: Performance of this tool may vary depending on variations in local line voltage. Exten-

sion cord usage may also affect tool performance.

Warning:The warnings, cautions,and instructions discussed in this instruction manual

cannot cover all possible conditions and situations that may occur. It must be under-

stood by the operator that common sense and caution are factors which cannot be

built into this product, but must be supplied by the operator.

Unpacking

When unpacking, check to make sure that all the parts are included. Refer to the Assembly

Drawing and Parts List at the end of this manual. If any parts are missing or broken, please

call Harbor Freight Tools at the number on the cover of this manual as soon as possible.

Operation

Warning: Fill with compressor oil before using; running with no or low oil voids war-

ranty. Optimal oil tank capacity is 8.8 ounces.

Oil Gauge

The Dip Stick (2) oil gauge is used to determine if oil is needed.

To check the oil:

1. Unscrew

(do not pull)

the Dip Stick out.

2. Check the level of the oil.

There are two lines on the bottom of the Dip Stick. The oil

level should always be at maximum.

REV 02/04

Page 5SKU 46168

3. Add 30-weight, non-detergent oil through the Gauge’s hole as necessary, but do not

overfill. Screw in the Oil Gauge, being careful not to strip the plastic threads.

Hose Connections

1. Close the Air ControlValve (7) (right or left).

2. Connect the high pressure air hose to the air outlet.

The outlet is 1/4” NPT. For easy connection or removal, a quick coupler (not supplied)

should be installed on the end of the outlet.

3. Turn the Air Control Valve to the middle position to allow the air to pass.

Warning: Do not remove the factory sealed Air Control Valve (7); removal voids war-

ranty.

Turning Compressor On

1. Plug the power cord into an electrical outlet with a grounding prong.

2. Pull up on the On/Off Pressure Switch (3) to turn on. Push down on

the Switch to shut off.

3. Allow the Tank to fill to 80 PSI before using.

With the Air Compressor turned on, operation is automatic and

under the control of the internal pressure switch.

Adjusting Pressure Switch

Caution:The internal pressure switch is adjustable but changes to the pressure levels

are not recommended; any change to the automatic On/Off pressure levels will cause

additional stress on the motor which may result in shortened motor life.

Using the Pressure ReliefValve

The Pressure Relief Valve (4) is used when decompression is

needed quickly and efficiently.

1. Press the On/Off Pressure Switch (3) down to turn power off.

2. Pull on the Pressure Release Valve (4) ring to release

pressure.

Empty Air and Condensation

The Water Spill Valve (11) is located underneath the AirTank.It must

be used daily to release all trapped moisture through this valve. It will also get rid of any

condensation that may cause tank corrosion.

Warning: Do not open the Water Spill Valve (11) so that more than four threads are

showing.

1. Push down on the On/Off Pressure Switch (3) to turn the compressor off. Unplug the

electrical plug.

2. Unscrew theWater Spill Valve (11) two to three turns.

3. When all pressure is released, close the valve again. Plug in the electrical plug.

Maintenance

1. Check compressor oil level daily. Fill if necessary with 30-weight, non-detergent

oil.

2. Purge the AirTank daily of all air and moisture to prevent corrosion.

3. Store the Air Compressor in a clean and dry location.

4. Check all air fittings for leaks before using.

5. To extend the life of your air tools, it is recommended to install an oiler and water filter

in series with the air output line of the Air Compressor (sold separately) as shown

below.
