1. Use only 3-wire extension cords that have 3-prong

grounding plugs and 3-pole receptacles that accept the air compressor’s plug.

2. When using the air compressor at a considerable

distance from the power source, use an extension cord heavy enough to carry the current that the compressor will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size required in an extension cord.

3. Only round jacketed cords listed by Underwriter’s

Laboratories (UL) should be used. ** Ampere rating (on air compressor data plate) 0-2.0 2.1-3.4 3.5-5.0 5.1-7.0 7.1-12.0 12.1-16.0 Cord Length Wire Size (A.W.G.) 25’141414141414 50’141414141412 100’ 14 14 14 12 10 – ** Used on 12 gauge - 20 amp circuit. NOTE: AWG = American Wire Gauge

4. When working with the air compressor outdoors, use

an extension cord that is designed for outside use. This is indicated by the letters “W-A” on the cord’s jacket.

5. Before using an extension cord, inspect it for loose or

exposed wires and cut or worn insulation.

Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a compressor. Failure to do so can result in serious personal injury.

Check the extension cords before each use. If damaged, replace immediately. Never use the air compressor with a damaged cord since touching the damaged area could cause electrical shock resulting in serious personal injury. NOTE: Use longer air hoses instead of long extension cords. Your air compressor will run better and last longer ELECTRICAL CONNECTION

1. This air compressor is powered by a precision built

electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current).

2. Do not operate this compressor on direct current (DC).

A substantial voltage drop will cause a loss of power and the motor will overheat. If the air compressor does not operate when plugged into an outlet, double check the power supply.

1. The no-load speed of the electric motor varies by

model and specifi cation. The motor speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor’s horsepower rating.

2. A line intended only for lights cannot properly carry

a compressor motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one compressor may not be able to support two or three compressors. GROUNDING INSTRUCTIONS

1. This product must be grounded. In the event of an

electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This air compressor is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. 00BookEC914SNA.indb800BookEC914SNA.indb8 2020/06/0813:46:332020/06/0813:46:339 English

2. Do not modify the plug provided. If it will not fi t the

outlet, have the proper outlet installed by a qualifi ed electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock.

3. We recommend that you never disassemble the

compressor or try to do any rewiring in the electrical system. Any repairs should be performed only by metabo HPT Service Centers. Should you be determined to make a repair yourself, remember that the green colored wire is the “grounding” wire. Never connect this green wire to a “live” terminal. If you replace the plug on the power cord, be sure to connect the green wire only to the grounding (longest) prong on a 3-prong plug.

4. Replace a damaged or worn cord immediately.

5. This product is for use on a nominal 120-V circuit and

has a grounding plug similar to the plug illustrated in Fig. 1. Only connect the product to an outlet having the same con-fi guration as the plug. Do not use an adapter with this product.

6. Never use an electrical adapter with this

grounded plug. Grounding pin Ground outlet box 120V grounded outlet Fig. 1

Avoid electrical shock hazard. Never use this compressor with a damaged or frayed electrical cord or extension cord. Inspect all electrical cords regularly. Never use in or near water or in any environment where electric shock is possible.

NOTE: The information contained in this Instruction Manual is designed to assist you in the safe operation and maintenance of the compressor. Some illustrations in this Instruction Manual may show details or attachments that diff er from those on your own compressor.

KNOW YOUR AIR COMPRESSOR

Before attempting to use this product, familiarize yourself with all operating features and safety rules. (Fig. 2)

OIL-FREE UNIVERSAL MOTOR

Your air compressor features permanently lubricated bearings.

This switch is used to start or stop the air compressor. Moving the switch to the (ON) position will provide automatic power to the pressure switch which will allow the motor to start when the air tank pressure is below the factory set cut-in pressure. When in the (ON) position, the pressure switch stops the motor when the air tank pressure reaches the factory set cut-out pressure. Moving the switch to the (OFF) position will remove power from the motor and stop the air compressor.

ELECTRIC MOTOR & AIR COMPRESSOR PUMP

The motor is used to power the pump. The electric motor has a thermal overload protector. If the motor overheats for any reason, the thermal overload will cut off power, thus preventing the motor from being damaged. Wait until the motor is cool. Motor resets automatically. Air compressor pump: to compress air, the piston moves up and down in the cylinder. On the down stroke, air is drawn in through the air intake valve while the exhaust valve remains closed. On the upstroke, air is compressed, the intake valve closes and compressed air is forced out through the exhaust valve, into the discharge line, through the check valve and into the air tank. SAFETY VALVE This valve is designed to prevent system failures by relieving pressure from the system when the compressed air reaches a predetermined level. The valve is preset by the manufacturer and must not be modifi ed in any way. DRAIN VALVE The drain valve is used to remove moisture from the air tank.

The tank pressure gauge indicates the pressure of the air in the tank.

REGULATOR PRESSURE GAUGE

The current line pressure is displayed on the regulator pressure gauge. This pressure can be adjusted by rotating the pressure regulator knob.

PRESSURE REGULATOR KNOB

Use the pressure regulator knob to adjust the amount of air being delivered through the hose. The air pressure coming from the air tank is controlled by the regulator knob. Turn the pressure regulator knob clockwise to increase discharge pressure and counterclockwise to decrease discharge pressure. Follow tool operating instructions for recommended pressure range. AIR TANK The tank is used to store the compressed air. QUICK COUPLER The outlet is used to connect the 1/4 in. NPT air hose. 00BookEC914SNA.indb1100BookEC914SNA.indb11 2020/06/0813:46:342020/06/0813:46:3412 English OVERLOAD PROTECTOR This air compressor is equipped with a thermal overload device which will turn the air compressor off automatically, if the air compressor becomes overheated. If the motor turns OFF repeatedly, check for the following possible causes fi rst: Low Voltage from the outlet. Lack of proper ventilation or outside air or room temperature too high. Extension cord too long or wrong gauge wire used. To reset the air compressor: (1) Turn the air compressor off . (2) Unplug the air compressor and allow it to cool for 30 minutes. (3) Plug the air compressor into an approved outlet. (4) Turn the air compressor on. DUTY CYCLE: To avoid overheating of the electric motor, this compressor is designed for intermittent operation as indicated on the dataplate: S3 50 means 5 minutes ON and 5 minutes OFF. If the compressor run time exceeds the S3 50 duty cycle, then the application requires more air than the compressor is capable to deliver. To ensure tool performance, the SCFM output of the compressor should exceed the CFM requirement of the tool by 20%. ASSEMBLY UNPACKING This product has been shipped completely assembled.

Always release all pressure, disconnect from power supply, and allow unit to cool to the touch before cleaning or making repairs on the air compressor GENERAL MAINTENANCE Humidity in the air causes condensation to form in the air tank. This condensation should be drained daily and/or every hour, using the instructions found in Draining the Tank. The safety valve automatically releases air if the air receiver pressure exceeds the preset maximum. Check the safety valve before each use following the instructions found in Checking the Safety Valve. Inspect the tank yearly for rust, pin holes, or other imperfections that could cause it to become unsafe. TROUBLESHOOTING Problem Possible Cause Solution The compressor does not run. Loss of power or overheating. There is no electrical power being supplied to compressor or the power switch is in the OFF position. A fuse has blown at the power supply. A breaker has tripped at the power supply. Thermal overload open. The pressure switch is bad. Tank is full of air. Check for proper use of extension cord. Check to be sure the compressor is plugged in and the power switch is in the ON position. Replace the fuse at the power supply. Reset the breaker at the power supply and determine why the problem happened. First unplug the compressor and wait until it becomes cool. Motor will restart when cool. Replace the pressure switch. Compressor will turn on when tank pressure drops to cut-in pressure. 00BookEC914SNA.indb1600BookEC914SNA.indb16 2020/06/0813:46:342020/06/0813:46:3417 English Problem Possible Cause Solution The motor hums, but does not run or runs slowly. The voltage from the power supply is low. The gauge wire or the length of extension cord is wrong. The motor winding is shorted or broken. The unloader or check valve is defective. Check the voltage with a voltmeter. Use the correct wire gauge and length extension cord. Take the compressor to a service center. Take the compressor to a service center. The fuses blow or the circuit breaker trips repeatedly. The fuse size is incorrect or the circuit is overloaded. The gauge wire or the length of extension cord is wrong. The unloader or check valve is defective. Check the fuse or breaker at the power supply is the correct size and type. Be sure to use only time-delay fuses to avoid overloading a curcuit, disconnect other electrical appliances from circuit or operate compressor on its own branch circuit. Use the correct wire gauge and length extension cord. Take the compressor to a service center. The thermal overload protector cuts out repeatedly. The voltage from the power supply is low. A poorly ventilated room is causing the motor to overheat. The gauge wire or the length of extension cord is wrong. Check the voltage with a voltmeter. Move the compressor to well-ventilated area. Check for proper gauge wire and cord length. The air receiver pressure drops when the compressor shuts off . The connections are loose or leaking (fi ttings, tubing, etc.). The drain valve is loose. The check valve is leaking. Check all the connections with soapy water and look for bubbles. Tighten any loose conections until the leak stops. Tighten the drain valve. Take the compressor to a service center.
