SPECIFIC SAFETY RULES AND PRECAUTIONS

CAUTION!1. Your Warranty is voided if: You drop theAir Compressor. Always lift

the Air Compressor using its Handle.

Do not expose to a high-dust environment. Dusty conditions may increase wear on

2. the Compressor.

DANGER!3. This Air Compressor is NOT equipped and should not be used “as-is”

to supply breathing air. For any application of air for human consumption, you

must t the Air Compressor with suitable in-line safety and alarm equipment (not

included). This additional equipment is necessary to properly lter and purify the air

to meet minimal specications for Grade D breathing as described in Compressed

Gas Association Commodity Specication G 7.1-1966, OSHA 29 CFR 1910. 134,

and/or Canadian Standards Associations (CSA). In the event the Air Compressor

is used for the purpose of breathing air application and proper in-line safety and

alarm equipment is not simultaneously used, existing warranties are void, and

Harbor Freight Tools disclaims any liability whatsoever for any loss, personal injury,

or damage.

DANGER!4. Never attempt to repair or modify the Air Tank (53). Welding, drilling,

or any other modication will weaken the Tank resulting in damage from rupture or

explosion. Always replace worn, cracked, or damaged Tanks.

GROUNDING

WARNING!

Improperly connecting the grounding wire can result in the risk of electric shock.

Check with a qualied electrician if you are in doubt as to whether the outlet is

properly grounded. Do not modify the power cord plug provided with the tool.

Never remove the grounding prong from the plug. Do not use the tool if the

power cord or plug is damaged. If damaged, have it repaired by a service facility

before use. If the plug will not t the outlet, have a proper outlet installed by a

qualied electrician.

GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS

1. Tools marked with “Grounding Required” have a three wire cord and three prong

grounding plug. The plug must be connected to a

properly grounded outlet. If the tool should

electrically malfunction or break down, grounding

provides a low resistance path to carry electricity

away from the user, reducing the risk of electric

shock. (See 3-Prong Plug and Outlet.)

The grounding prong in the plug is connected

2. through the green wire inside the cord to the

groundingsysteminthe tool. Thegreenwireinthe

cord must be the only wire connected to the tool’s

grounding system and must never be attached to an electrically “live” terminal.

(See 3-Prong Plug and Outlet.)

Yourtoolmustbepluggedintoanappropriateoutlet,properlyinstalledandgrounded3. in accordance with all codes and ordinances. The plug and outlet should look like

those in the following illustration. (See 3-Prong Plug and Outlet.)

1. Incorporate an in-line oiler, shut-off valve, regulator with pressure gauge, and lter

for best service, as shown in the diagram above. An in-line shutoff valve is an

important safety device because it controls the air supply even if the air hose

is ruptured.

Note: If an automatic oiler system is not used, add a few drops of Pneumatic Tool Oil to

the airline connection before operation. Add a few more drops after each hour of

continual use.

Attach an air hose to the compressor’s air outlet. Connect the air hose to the air

2. inlet of the tool.

Other components, such as a connector and quick coupler, will make operation3.

more efcient, but are not required.

WARNING! TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:

Do not install a female quick coupler on the tool. Such a coupler contains an

air valve that will allow the air tool to retain pressure and operate accidentally after

the air supply is disconnected.

Connect a high pressure air hose (not included) to the Pressure Regulator (24).1. Connect an air blow gun (not included) to the other end of the air hose. Turn the

compressor on. Refer to Hose Connection Instructions on page 8.

When the maximum air pressure, 100 PSI, is reached as indicated by the Tank

2. Pressure Gauge (26), the motor will stop.

Blow air out of the blow gun while you turn the Pressure Regulator (24) knob3. to adjust Pressure Regulator (24). Turn the Pressure Regulator (24) knob

counterclockwise to decrease the PSI, turn it clockwise to increase the PSI.

When the Regulated Pressure Gauge (70) shows the pressure that you want to

limit the compressor to, the Pressure Regulator (24) is set. (See Figure C.)

Between the Pressure Regulator knob and valve body, a narrow ring acts as a

4. lock-ring for the knob. Rotate the ring in a counterclockwise direction and tighten

it against the knob to secure the setting. (See Figure C.)

NOTE: When the maximum air pressure, 100 PSI, is reached as indicated by the

Tank Pressure Gauge (26), the motor will stop. The Compressor will automatically

restart when the air pressure drops below 85 PSI. (See Figure C.)

To Stop The Compressor:

Push the ON/OFF Power Switch (45) to its “OFF” position.1.

Unplug the Air Compressor from its electrical outlet. Place a collector can (not2. included) under the Air Tank (53) and turn the Drain Valve (54) counterclockwise.

Pull out on the Safety Valve (25) to release all remaining air pressure from the3. Air Tank (53). (See Figure C.) This will not only drain the air, but will also drain

any accumulated moisture. After all air is drained, turn the Safety Valve (25)

clockwise.

Squeeze the trigger on the pneumatic tool to release any remaining air pressure

4. from the tool. Then disconnect the air hose from the tool, and store the tool in a

clean, dry, safe location out of reach of children.

Remove any moisture in the Air Tank (53) by opening the Tank Drain Valve (54).

5. Then, retighten the Drain Valve (54). (See Figure B.)
