section of this

manual. Use of unauthorized parts or failure to follow maintenance instructions

may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES AND PRECAUTIONS

1. Maintain labels and nameplates on the Air Compressor. These carry

important information. If unreadable or missing, contact Harbor Freight Tools for a

replacement.

2. DANGER! This Air Compressor is NOT equipped with and should not be

used “as is” to supply breathing quality air. For any application of air for human

consumption, you must fit the Air Compressor with suitable inline safety and

alarm equipment (not included). This additional equipment is necessary to

properly filter and purify the air to meet minimal specifications for Grade D

breathing as described in Compressed Gas Association Commodity Specification

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 inline 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.

5. Check for misalignment or binding of moving parts, breakage of parts, and

any other condition that may affect the tool’s operation. If damaged, have

the tool serviced before using. Many accidents are caused by poorly

maintained tools.

3. Make sure all tools and equipment used with the Air Compressor are rated

to the appropriate capacity. Do not use any tool or equipment that does not

operate from 85 PSI to 125 PSI.

4. Drain the Air Compressor every day. Do not allow excessive moisture to build

up inside the Air Compressor. Do not open the water Drain Valve (4) with more

than 10 PSI of air pressure in the Compressor.

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 Figure A.)

2. The grounding prong in the plug is connected through the green wire inside the

cord to the grounding system in the tool. The green wire in the cord must be the

only wire connected to the tool’s grounding system and must never be attached

to an electrically “live” terminal. (See Figure A.)

3. Your tool must be plugged into an appropriate outlet, properly installed and

grounded in accordance with all codes and ordinances. The plug and outlet

should look like those in the following illustration. (See Figure A.)

AIR COMPRESSOR CONTROLS

1. Pressure Switch (57): The Pressure Switch turns the Air Compressor on and

off. When in the “ON” position, the Pressure Switch allows the Compressor to

automatically adjust to its “run” stage when the air pressure inside the Air Tank

(3) falls below 85 PSI. The Pressure Switch also automatically turns the Com

pressor to its “idle” stage when the air pressure inside the Air Tank reaches 125

PSI. Always keep the Pressure Switch in its “OFF” position when the unit is not

in use. (See Figure D, next page.)

2. Safety Valve (10): If the Pressure Switch (57) does not shut down the Motor of

the Air Compressor when the pressure reaches 125 PSI, the Safety Valve will

automatically pop open to prevent over-pressurization. To operate manually, pull

the ring on the Safety Valve to relieve air pressure in the Air Tank (3).

(See Figure D, next page.)

3. Tank Pressure Gauge (13): The Tank Pressure Gauge measures the pressure

level of the air stored in the Air Tank (3), and is not adjustable by the operator.

(See Figure D.)

SKU 94355 For technical questions, please call 1-800-444-3353 PAGE 10

4. Pressure Regulator Knob (14): The Pressure Regulator Knob enables the

operator to adjust output pressure to the pneumatic tool being used. To increase

the amount of air pressure to the tool, turn the Pressure Regulator Knob clock

wise. To decrease the amount of air pressure to the tool, turn the Pressure

Regulator Knob counterclockwise. (See Figure D.)

5. Tool Pressure Gauge (13): The Tool Pressure Gauge measures the pressure

level of air flowing to the pneumatic tool being used, and is adjustable using the

Pressure Regulator Knob (14). (See Figure D.)

6. Quick Coupler (11): The Quick Coupler connects to the air output hose which,

in turn, connects to the pneumatic tool being used. To connect an air hose, push

in on the Quick Coupler. To disconnect the air hose, pull back on the Quick

Coupler collar. (See Figure D.)
