COMPRESSOR FEATURES  
1) MOTOR/PRESSURE SWITCH: This switch is used to start or stop the air  
compressor. Moving the switch to the “Auto” (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 Start/ Stop Option,  
the pressure switch stops the motor when the air tank pressure reaches the factor  
set “cut out” pressure. For safety purposes, this switch also has a pressure release  
valve located on the side of the switch designed to automatically release compressed  
air from the air compressor pump head and its discharge line when the air compressor  
reaches “cut-out” pressure or is shut off. This allows the motor to restart freely. Moving  
the switch to the “Off” position will remove power from the pressure switch and stop  
the air compressor.  
1
ON  
OFF

2) MOTOR THERMAL OVERLOAD: The electric motor has a manual 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 before pressing the thermal overload button to reset and begin working again.  
3) AIR INTAKE FILTER: This filter is designed to clean air coming into the pump. To  
ensure the pump continually receives a clean, cool, dry air supply this filter must  
always be clean and ventilation opening free from obstructions. The filter can be  
removed for cleaning by using warm, soapy water. Rinse the filter and air dry. Replace  
filter when necessary.  
3
4) AIR COMPRESSOR PUMP: To compress air, the pistons move up and down in  
the cylinders. On the downstroke, air is drawn in through the air intake valves while  
the exhaust valves remain closed. On the upstroke, air is compressed, the intake  
valves close and compressed air is forced out through the exhaust valves, into the  
discharge line, through the check valve and into the air tank.  
5) SAFETY RELIEF 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 modified in any way.  
To verify the valve is working properly, pull on the ring. Air pressure should escape.  
When the ring is released, it will reseat.  
5
6
6) AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air  
tank(s) after the air compressor is shut off. NEVER attempt to open the drain valve  
when more than 10 PSI of air pressure is in the air tank! To open the drain valve,  
turn the knob counterclockwise.  
8
7) AIR TANK PRESSURE GAUGE: The air tank pressure gauge indicates the  
reserve air pressure in the air tank (s).  
7
8) OUTLET PRESSURE GAUGE: The outlet pressure gauge indicates the air  
pressure available at the outlet side of the regulator. This pressure is controlled  
by the regulator and is always less or equal to the air tank pressure.  
9) PRESSURE REGULATOR: The air pressure coming from the air tank is  
controlled by the regulator knob. Turn the pressure regulation knob clockwise to  
increase discharge pressure, and counterclockwise to decrease discharge  
pressure.  
9
10  
10) OIL DIPSTICK: The dipstick will register the amount of oil in the pump. Oil level  
should be checked on a daily basis to ensure it does not exceed the maximum  
notch or fall below the minimum notch on the dipstick

PREPARATION  
INITIAL SET-UP:  
1. Read safety warnings before setting-up air compressor.  
2. Ensure the oil level is above the minimum notch and below the maximum notch on the dipstick. If low, add  
compressor pump oil.  
LOCATION:  
CAUTION  
In order to avoid damaging the air compressor, do not incline the air compressor  
transversely or longitudinally more than 10°.  
1. Place air compressor at least 12 inches away from obstacles that may prevent proper ventilation.  
Do not place air compressor in an area:  
-where there is evidence of oil or gas leaks.  
-where flammable gas vapors or materials may be present.  
WARNING  
Serious injury or death may occur if electrical sparks from motor and pressure switch  
come in contact with flammable vapors, combustible dust, gases or other  
combustible materials. When using the air compressor for spray painting, place the  
air compressor as far away I from the work area as possible, using extra air hoses instead of  
extension cords.  
-where air temperatures fall below 32°F or exceed 104°F.  
-where extremely dirty air or water could be drawn into the air compressor.  
ELECTRICAL:  
DANGER  
Improper connection of the equipment-grounding conductor can result in a risk  
of shock or electrocution. Check with a qualified electrician or service personnel  
if you are in doubt as to whether the outlet is properly grounded. Do not use any type of  
adapter with this product. If repair or replacement of the cord or plug is necessary, do not  
connect the grounding wire to either flat blade terminal. The wire with insulation having  
an outer surface that is green with or without yellow stripes is the grounding wire.  
WARNING  
This product must be grounded. If there should be a malfunction or breakdown,  
grounding provides a path of least resistance for electric current to reduce the  
risk of electric shock. This product is equipped with a cord having an equipment-  
grounding conductor and a grounding type plug. The plug must be plugged into an  
appropriate outlet that is properly installed and grounded in accordance with all local  
codes and ordinances.  
1. SENCO® DOES NOT RECOMMEND THE USE OF EXTENSION CORDS as this can create power loss and  
overheating of the motor. Use of an additional air hose is recommended rather than an extension cord. If use of an  
extension cord is unavoidable, it should be plugged into a GFCI found in circuit boxes or protected receptacles.  
When using an extension cord, observe the following:  
Cable Length  
Up to 25 feet  
Up to 100 feet  
Up to 150 feet  
Up to 250 feet  
Wire Gauge

Use only 3-blade extension cords that have 3-blade grounding-type plugs and 3-slot cord connectors that will  
accept the plug from the product. Use only extension cords having an electrical rating not less than the rating of  
the product. Do not use damaged extension cords. Examine extension cord before using and replace if damaged.  
Do not abuse extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp  
edges. Always shut off the air compressor switch before removing the plug from the receptacle.

2. Plug the power cord into a grounded outlet.  
3. Move the lever on the pressure switch box to the “AUTO” position.  
4. START/STOP OPTION: Turn it completely clockwise to the fully closed position. This will allow the air compressor  
to “START” building up pressure in the air tanks and “STOP” when correct pressure is achieved. When pressure  
drops with usage, the air compressor will “START” building up pressure again.  
CONSTANT RUN OPTION: Locate the adjustment knob at the top of the pilot valve. Turn it completely  
counterclockwise to the fully open position. The air compressor is now set up to “CONSTANTLY” build up  
pressure. When pressure reaches the preset level in the air tank, pressure will bleed through the pilot valve.  
5. Set pressure by adjusting the pressure regulator knob counterclockwise for less pressure and clockwise for  
more pressure.  
6. If you notice any unusual noise or vibration, stop the air compressor and refer to “Troubleshooting”.  
SHUTDOWN:  
1. To stop the air compressor, move the lever on the pressure switch box to the “OFF” position. NEVER stop the  
air compressor by unplugging it from the power source. This could result in risk of electrocution.  
2. Drain air from the air tanks by releasing air with an attached air tool or by pulling on the safety relief valve rings.  
3. Once pressure in the air tanks register under 10 pounds, open the drain valve under each air tank to drain any  
moisture.  
4. Allow the air compressor to cool down.  
5. Wipe air compressor clean and store in a safe, non-freezing area.
