provide automatic power to the pressure

switch and OFF to remove power at the

end of each use.

PRESSURE SWITCH

The pressure switch (J) automatically

starts the motor when the air tank

pressure drops below the factory set cut-

in pressure. It stops the motor when the air tank pressure reaches

the factory set cut-out pressure.

PRESSURE RELEASE VALVE

The pressure release valve located on the side of the pressure

switch, is designed to automatically release compressed air from

the compressor head and the outlet tube when the air compressor

reaches cut-out pressure or is shut off. The pressure release valve

allows the motor to restart freely. When the motor stops running,

air will be heard escaping from this valve for a few seconds. No air

should be heard leaking when the motor is running or after the unit

reaches cut-out pressure.

SAFETY VALVE

If the pressure switch does not shut off the air compressor at its cut-

out pressure setting, the safety valve (G) will protect against high

pressure by popping out at its factory set pressure (slightly higher

than the pressure switch cut-out setting).

CHECK VALVE

When the air compressor is operating, the check

F

valve (F) is open, allowing compressed air to enter

the air tank. When the air compressor reaches cut-

out pressure, the check valve closes, allowing air

pressure to remain inside the air tank.

TANK PRESSURE GAUGE

The tank pressure gauge (B) indi-

D

C

E

B

cates the reserve air pressure in

the tank.

OUTLET PRESSURE GAUGE

• Do not modify the plug provided. If it does not fit the available

outlet, a correct outlet should be installed by a qualified electrician.

• Repairs to the cord set or plug MUST be made by a

qualified electrician.

Extension Cords

Using extension cords is not recommended. The use of extension

cords will cause voltage to drop resulting in power loss to the motor

and overheating.

Instead of using an extension cord, increase the working reach of

the air hose by attaching another length of hose to its end. Attach

additional lengths of hose as needed.

If an extension cord must be used, be sure it is:

• a 3-wire extension cord that has a 3-blade grounding plug, and a

3-slot receptacle that will accept the plug on the product

• in good condition

• no longer than 50 feet (15,2 m)

• 12 gauge (AWG) or larger. (Wire size increases as gauge

number decreases. 10 AWG and 8 AWG may also be used. DO

NOT USE 14 OR 16 AWG.)

Voltage and Circuit Protection

under Specifications.

13

English

CAUTION: Certain air compressors can be operated on a

15 amp circuit if the following conditions are met.

• Voltage supply to circuit must comply with the National

Electrical Code.

• Circuit is not used to supply any other electrical needs.

• Extension cords comply with specifications.

• Circuit is equipped with a 15 amp circuit breaker or 15 amp

time delay fuse. NOTE: If compressor is connected to a circuit

protected by fuses, use only time delay fuses. Time delay fuses

should be marked “D” in Canada and “T” in the US.

If any of the above conditions cannot be met, or if operation of the

compressor repeatedly causes interruption of the power, it may be

necessary to operate it from a 20 amp circuit. It is not necessary

to change the cordset.

Compatibility

Air tools and accessories that are run off the compressor must be

compatible with petroleum-based products. If you suspect that a

material is not compatible with petroleum products, an air line filter

for removal of moisture and oil vapor in compressed air is required.

NOTE: Always use an air line filter to remove moisture and oil vapor

when spraying paint.

Location

Place the air compressor in a clean, dry and well ventilated area

at least 12" (30.5 cm) away from the wall or other obstructions

that will interfere with the flow of air. Keep the compressor away

from areas that have dirt and/or volatile fumes in the atmosphere.

These impurities may clog the intake filter and valves, causing

inefficient operation.

The air compressor pump and shroud are designed to allow for

proper cooling. The ventilation openings on the compressor are

necessary to maintain proper operating temperature. Do not place

rags or other containers on or near these openings.

Place the air compressor on a flat surface resting on the rubber feet.

* To check for air leaks apply a solution of soapy water around

joints. While compressor is pumping to pressure and after pressure

cuts out, look for air bubbles to form.

** The pump oil must be changed after the first 20 hours of

operation. Thereafter, when using

SAe 5W-40 full synthetic

oil,

change oil every 200 hours of operation or once a year, whichever

comes first.

+ Perform more frequent in dusty or humid conditions

Checking Safety Valve (Fig. 1)

WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and

surrounding parts are very hot, do not touch (see the Hot Surfaces

identied in Fig. 2). Allow compressor to cool prior to servicing.

WARNING: Risk of bursting. If the safety valve does not work

properly, over-pressurization may occur, causing air tank rupture or

anexplosion.

Before starting compressor, pull the ring on the safety valve to

make sure that the safety valve operates freely. If the valve is stuck

or does not operate smoothly, it must be replaced with the same

type of valve.

Checking Air Filter Element (Fig. 1)

WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and

surrounding parts are very hot, do not touch (see the Hot Surfaces

identied in Fig. 2). Allow compressor to cool prior to servicing.

1. Ensure the On/Off switch (A) is in the OFFposition.

2. Allow unit tocool.

3. Remove air lter (N) fromunit.

4. Carefully pry lter top frombase.

5. Remove element from lterbase.

6. If element needs cleaning, blow out with air. Replace if needed.

Purchase replacement parts from your local dealer or authorized

service center. Always use identical replacementparts.

7. Place element back in lter base.

8. Snap lter top to lter base.

9. Reassemble air lter to unit. Ensure exhaust outlet pointsdown.

CAUTION: Risk of unsafe operation. Do not operate without air

inlet lter

Draining Air Tank (Fig. 1)

WARNING: Risk of unsafe operation. Risk from noise. Air

tanks contain high pressure air. Keep face and other body parts

away from outlet of drain. Use safety glasses [ANSI Z87.1 (CAN/

CSA Z94.3)] when draining as debris can be kicked up into face.

Use ear protection [ANSI S12.6 (S3.19)] as air ow noise is loud

whendraining.

NOTE: All compressed air systems generate condensate that

accumulates in any drain point (e.g. tanks, filter, aftercoolers,

dryers). This condensate contains lubricating oil and/or substances

which may be regulated and must be disposed of in accordance with

local, state, and federal laws and regulations.

1. Ensure On/Off switch is in the OFFposition.

2. Move compressor into an inclined position so drain valve (H) is

at the lowest point (this will assist in removing moisture, dirt, etc.

from air tanks)

3. Place a suitable container under the drain valve to catchdischarge.

4. Grasp knurled knob on drainvalve.

5. Slowly rotate knob to gradually bleed air from airtank.

WARNING: Risk of bursting. Drain air tank daily. Water will con-

dense in air tank. If not drained, water will corrode and weaken the

air tank causing a risk of air tankrupture.

CAUTION: Risk of property damage. Drain water from air tank may

contain oil and rust, which can cause stains.

6. When air tank pressure gauge reads 10 PSI (68,9 kPa), rotate

valve to the fully openposition.

7. Close drain valve whennished.

Compressor Pump Oil (Fig. 1)

CHECKING OIL

WARNING: Hot surfaces. Risk of burn. Aftercooler,

pump head, and surrounding parts are very hot,

do not touch (see the Hot Surfaces identied in

Fig. 2). Allow compressor to cool prior to servicing.

1. Ensure On/Off switch is in the OFFposition.

2. Place unit on a at levelsurface.

3. Remove dipstick (K) and wipeclean.

4. Reinsert dipstick fully into oil ll port for a few

seconds to allow oil to collect on thedipstick.

5. Remove oil dipstick to read oil level. Oil should not

exceed top raised line on dipstick. If oil is below

lower mark, add same type of oil in crankcase and

follow Steps 4 -6.

NOTE: When lling the crankcase, the oil ows

very slowly into the pump. If the oil is added too

quickly, it will overow and appear to befull.

CAUTION: Risk of unsafe operation. Overlling with

oil will cause premature compressor failure. Do notoverll.

6. Replacedipstick.

CHANGING OIL

NOTE: Pump oil contains substances that are regulated and must

be disposed of in accordance with local, state and federal laws

and regulations.

WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and

surrounding parts are very hot, do not touch (see the Hot Surfaces

identied in Fig. 2). Allow compressor to cool prior to servicing.

Glossary

CFM: Cubic feet perminute.

SCFM: Standard cubic feet per minute; a unit of measure of air delivery.

PSI: Pounds per square inch; a unit of measure ofpressure.

kPa (kilopascal): Metric pressure measurement. 1 kilopascal equal 1000 pascals.

Code Certification: Products that bear one or more of the following marks: UL, CUL, ETL, CETL, have been evaluated by OSHA certied

independent safety laboratories and meet the applicable Underwriters Laboratories Standards forSafety.

Cut-In Pressure: While the motor is off, air tank pressure drops when accessory is used. When the tank pressure drops to a certain low level

the motor will restart automatically. The low pressure at which the motor automatically restarts is called cut-in pressure.

Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain

high pressure before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high pressure

at which the motor shuts off is called cut-out pressure.

Branch Circuit: The circuit carrying electricity from electrical panel tooutlet.

Duty Cycle: For proper operation of your air compressor, it is recommended that a 50% duty cycle be maintained; that is, the air compressor

should not run more than 5 minutes in any 10 minuteperiod.
