GLOSSARY

CFM: Cubic feet per minute.

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

PSIG: Pounds per square inch gauge; a unit of measure of pressure.

ASME: American Society of Mechanical Engineers; made, tested, inspected and registered to meet the standards of

ASME.

U.L. Listed: Products with the U.L. mark are listed by

Underwriters Laboratories, Inc. (U.L.). Samples of these prod-

ucts have been evaluated by U.L. and meet the applicable

U.L Standards of Safety.

California Code: Unit may comply with California Code 462

(L) (2)/(M) (2). Specification/model label is on the side of the

tank on units that comply with California Code.

Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your accessory or air tool. When

the tank pressure drops to a certain low level the motor will

restart automatically. The low pressure at which the motor automatically re-starts is called "cut-in pressure."

Cut-Out Pressure: When you turn on your air compressor

and it begins to run, air pressure in the air tank begins to build.

It builds to a certain high pressure before the motor automati-

cally 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."

DUTY CYCLE

All DeVilbiss Air Power manufactured air compressors should be operated on not more than a 50% duty cycle.

This means an air compressor that pumps air more than

50% of one hour, is considered misuse, because the air compressor is undersized for the required air demand.

Maximum compressor pumping time per hour is 30 minutes.

GENERAL INFORMATION

You have purchased an air compressor unit consisting of an aluminum 2 cylinder, single-stage air compressor pump (with cast iron sleeves), an air tank, wheels, handle, associated controls and instruments.

Your air compressor can be used for operating paint spray

guns, air tools, caulking guns, grease guns, air brushes, sandblasters, inflating tires and plastic toys, spraying weed

killers, insecticides, etc. An air pressure regulator is required for most of these applications.

An air line filter is usually required for removal of moisture and oil vapor in compressed air when a paint spray gun is used.

An in-line lubricator is usually required for air tools to prolong tool life.

Separate air transformers which combine the functions of air regulation and/or moisture end dirt removal should be used where applicable.

ON-RECEIPT INSPECTION

Each air compressor outfit is carefully tested and checked before shipment. With improper handling, damage may result in transit and cause problems in compressor operation.

Immediately upon arrival, check equipment for both concealed and visible damages to avoid expenses being incurred to correct such problems. This should be done regardless of any visible signs of damage to the shipping container.

If this product was shipped directly to you, report any damages to carrier and arrange for inspection of goods immediately.

For the location or a listing of the nearest DeVilbiss

Air Power Authorized Warranty Service Center, call our toll free number at 1-800-888-2468, Ext, 2.

DESCRIPTION OF OPERATION

Drain Valve: The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use.

Motor Thermal Overload Protector: The electric motor has

an automatic thermal overload protector.

If the motor over-

heats for any reason, the thermal overload protector wilJshut

off the motor. The motor must be allowed to cool before restarting.

ON/AUTO - OFF Switch (Pressure Switch): Turn this

switch ON to provide automatic power to the pressure switch

and OFF to remove power at the end of each use. The pressure

switch 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.

Air Intake Filter: This filter is designed to clean air coming

into the pump. This tilter must always be clean and ventilation

openings free from obstructions. See "Maintenance".

Air Compressor Pump: To compress air, the pistons moves

up and down in the cylinder. On the downstroke, air is drawn in through the air intake valves. The exhaust valve remains closed. On the upstroke of the piston, air is compressed. The intake valves close and compressed air is forced out through the exhaust valve, through the outlet tube, through the check

valve and into the air tank. Working air is not available until

the compressor has raised the air tank pressure above that required at the air outlet.

Check Valve: When the air compressor is operating, the

check valve is "open", allowing compressed air to enter the air tank. When the air compressor reaches "cut-our' pres-

sure, the check valve "closes", allowing air pressure to remain inside the air tank.

Pressure Release Valve: The pressure release valve lo-

cated 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. If the air is not released, the motor will try to start, but will be unable to. The pressure

release valve allows the motor to restart freely.

When the

motor stops running, air will be heard escaping from the valve for a few seconds. No air should be heard leaking when the motor is running, or continuous leaking after unitreaches cutout pressure.

Safety Valve: If the pressure switch does not shut off the air compressor at its cut-out pressure setting, the safety valve

will protect against high pressure by "popping out" at its factory set pressure (slightly higher than the pressure switch cut-out setting).

DESCRIPTION OF OPERATION (cont'd)

Outlet Pressure Gauge: The outlet pressure gauge indi-

cates 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 tank pressure. See "Operating

Procedures".

Tank Pressure Gauge: The tank pressure gauge indicates

the reserve air pressure in the tank.

Regulator: The air pressure coming from the air tank is controlled by the regulator knob. Turn the knob clockwise to increase pressure and counterclockwise to decrease pres-

sure. To avoid minor readjustment after making a change in

pressure setting, always approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce to some pressure less than that desired, then bring up to the desired pressure. Depending on the air requirements of each particular accessory, the cutlet regulated air pressure may have to be adjusted while you are operating the accessory.

Installing Handle

1. Insert the open end of the handle under the saddle (Fig. 1).

Before attaching handle, you may have to pull the open

ends of the handle apart so they fit tightly against the side

of the saddle. Looking in from the open end of the saddle,

position the handle toward the two bent tabs, on the inside

walls of the saddle. Slowly push the open ends of the

handle onto both tabs at the same time (Fig. 2). Continue pushing the handle into the saddle until the holes on the

side of the saddle and handle are in line.

2. Guide the straight end of each retaining clip through the saddle hole and both handle holes (Fig. 3).

3. Rotate each retaining c_ipclockwise and press down until it snaps into place over the pull handle (Fig. 4).

4. If the handle has excessive movement, it is improperly

installed, Check the following.

A. Are both tabs inside the handle (Step #1)?

B. Does each clip pass through both the saddle and handle (Step #2)?

ASSEMBLY INSTRUCTIONS

Items Needed for Assembly

• a 9/16" socket or open-end wrench for attaching the wheels

• a 3/8" open-end wrench to tighten handle screws

Installing Wheels, Handles, Rubber Foot Strip

It may be necessary to brace or support one end of the outfit when attaching the wheels because the air compressor will have a tendency to tip.

1. Remove the protective paper strip from the adhesivebacked rubber foot strip. Attack the rubber foot strip to the bottom of the air tank leg. Press firmly into place.

2. The leg bracket on the underside of the air compressor tank has 2 holes on each side for mounting the wheels.

Place one shoulder bolt through the hole in a wheel. On models with 10" wheels, push the bolt through the TOP hole of the leg bracket. For models with 8" wheels, push the bolt through the BOTTOM hole of the leg bracket.

Screw on one hex locking nut. The special locking nut does not turn freely. Tighten the nut firmly until it contacts the tank leg. The outfit will sit level if the wheels are properly installed.

NOTE

The side of the wheel, that the hub protrudes

out past the wheel edge, should be bolted to the compressor leg.

THE WHEELS AND HANDLE DO NOT PROVIDE

ADEQUATE CLEARANCE, STABILITY OR SUP-

PORT FOR PULLING THE UNIT UP AND DOWN

STAIRS OR STEPS. THE UNIT MUST BE UFTED

OR PUSHED UP A RAMP. DO NOT LIFT THE UNIT

BY THE MANIFOLD ASSEMBLY. THE UNIT CAN

BE DAMAGED.

INSTALLATION

PROCEDURES

AND BREAK-IN

Location of the Air Compressor

Operate the air compressor in a clean, dry and well ventilated

area. The fan bladed flywheel must be kept clear of obstruc-

tions that could interfere with the flow of air through the air intake filter. The pump crankcase and head are designed with fins to provide proper cooling.

If humidity is high, an air filter can be installed on the air outlet adapter to remove excessive moisture. Closely follow the instructions packaged with the filter for proper installation. It must be installed as close as possible to the accessory.Do

not place the air compressor where heat is excessive.

When locating the compressor outside, make sure there is a mimum of 12 inches on each side of the compressor. There

must be fresh air flow for proper cooling. DO NOT ALLOW

THE COMPRESSOR TO GET WET.

6

VoltageandCircuitProtection

Refer to your Parts Manual for voltage and circuit protection requirements of your compressor. Use only a fuse or circuit breaker that is the same rating as the branch circuit the air compressor is operated on. If the compressor is connected to

a circuit protected by fuses, use only dual element time delay

fuses, as noted in the Parts Manual.

rl_mJ dIs] _1

Certain air compressors can be converted from

120V to 240V operation.

When converting an air compressor to 240V operation, the attached three-prong 120V =ord assembly

must be replaced with a three-pronged 240V cord assembly that can be purchased through an Authorized Warranty Service Center.

To locate an Authorized Warranty Service Center nearest you, call us at 1-800-888-2468, Ext.

2, then 2.

Place unit on a level surface. Remove oil fill plug and slowly add a compressor oil such as Castrol Heavy Duty 30 weight until it is even with the top of the oil fill hole. (It must not be allowed to be lower than 3/8" -- 6 threads down -- from the top at any time.) When filling the crankcase, the oil flows very slowly into the pump. If the oil is added too quickly, it will overflow and appear to be full. Crankcase off capacity is 16

fluid ounces. Replace oil fill plug.

NOTE

Drain and refill the compressor pump crankcase after the first 100 hours of operation.

GROUNDING INSTRUCTIONS

Some models have a dual voltage motor, 120 and 240 volt.

They are wired for 120 volt but can be converted to 240 volt operation. Instructions for connecting the motor for operation at 240 volt can be found printed on the label attached to the side of the motor.

Certain air compressor models san be operated on a 15 amp circuit If:

1. Voltage supply to circuit is normal.

2. Circuit is not used to supply any other electrical needs (lights, appliances, etc.)

3. Extension cords comply with specifications in this manual.

4. Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse.

Extension Cords

To avoid voltage drop and power loss to the motor, and to prevent overheating, use extra air hose instead of an exten- sion cord.

If an extension cord must be used:

• use only a 3-wire extension cord that has a 3-blade ground-

ing plug and s 3-slot receptacle that will accept the plug on the extension cord.

• make sure the extension cord is in good condition.

• the extension cord should be no longer than 50 feet.

• the minimum wire size is 12 gauge (AWG). (Wire size in-

creases as gauge number decreases. 10 AWG and 8 AWG

may also be used. DO NOT USE 14 AWG or 16 AWG.)

Lubrication and Oil

Lf_[tT...tl]ll[o] _I

Multi-Viscosity motor oils, like 10W30, should not be used in an air cornpressor. They leave carbon depo6-

its on critical components, thus reducing porformanse and compressor life.

RISK OF ELECTRICAL SHOCI(J In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current.

This air compressor must be properly grounded.

The air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be used with an outlet that has been installed and grounded in accordance with all local codes and ordinances. The outlet must have the same configuration as the plug. See illustration. DO NOT USE AN ADAPTER.

Inspect the plug and cord before each use. Do not use if there are signs of damage.

IMPROPER GROUNDING CAN RESULT IN ELEC-

TRICAL SHOCK.

Do not modify the plug that has been provided. If it does not fit the available outlet, the correct outlet should be installed by a qualified electrician.

If repairing or replacing cord or plug, the grounding wire must be kept separate from the current-carrying wires. Never connect the grounding wire to a flat blade plug terminal. The grounding wire has insulation with an outer surface that is green - with or without yellow stripes.

If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualified electrician.

120 Volt aodals

24O VMt Models

Como_ are shim)ed without oil. Asman amount

of oil may be present in the pump upon receipt ofthe air compressor.

This is duets planttssting and does

not meanthat the pump €ontains oil. Do not attempt to eperatethis air compresssrwithout first adding oil to the crankcase.

Sedous damage can result from even limited operation unless filled with oil and broken in co_ectly.

Make sure to closely follow initial start-up procedures.

7

Piping

Plastic or PVC pipe is not designed for use with compressed air.

Regardless of its indicated pressure rating, plastic pipe can burst from air

pressure. Use only metal pipe for air distribution lines.

If a pipe line is necessary, use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air. If piping is over 100 feet long, use the next larger size.

Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.

Connect the piping to the 3/8" NPT air outlet opening at the end of the air tank.

Additional Regulators and Controls

Since the air tank pressure is usually greater than that which is needed, a separate regulator is employed to control the air pressure ahead of any individual air driven device.

Separate air transformers which combine the function of air regulation, moisture and dirt removal should be used where applicable.

Break-in Procedures

Im[_T_ltj_eT_l

Serious damage may result if the following break-in instructions are not closely followed.

This procedure is required:

1, Before the air compressor is put into service. (Before the

hose is installed)

2. When the check valve is replaced.

3. When a complete compressor pump is replaced.

a. Set the pressure switch lever to the "OFF" position. b. Plug the power cord into the correct branch circuit receptacle.

c. Turn the regulator clockwise (or open the shut-off

valve), opening it fully, to prevent air pressure build-up in the tank.

d. Move the pressure switch lever to "ON/AUTO". The compressor will start.

e. Run the compressor for 30 minutes. Make sure the regulator, or shut-off valve, is open and there is no tank pressure build-up.

f.

After 30 minutes, close the regulator by turning it counterclockwise or close the shut-off valve by turning the knob clockwise. The air receiver will fill to cut-out pressure and the motor will stop. The compres-

sor is now ready for use.

OPERATING PROCEDURES

Daily Start-Up Checklist

Perform the following checks before starting the compressor outfit.

1. Make sure that nothing is blocking the belt guard air openings or air filter inlet.

2. Pull the ring on all safety valve to make sure the valve moves freely and smoothly.

3. Check the oil level; add oil if necessary.

4. Clean or blow off fins or any part of compressor that

collects dust and dirt. Compressor will run cooler and provide longer service.

5. Before attaching an air hose or accessory make sure the pressure switch lever is in the "OFF" position.

Close the air regulator outlet by turning it counterclockwise.

6. Attach hose and accessory

Start the compressor outfit and check the following:

1. With the outlet valve closed, start the compressor outfit. Allow the outfit to pump up to cut-off pressure.

2. Make sure that all controls are operating correctly.

Refer to "Description of Operation" section of this manual.

3. Check all line fittings and piping for air leaks. Even minor leaks can cause the compressor to over

work, resulting in premature breakdown or unsatisfactory performance.

4. Check for any unusual vibration and noise.

5. Check for oil leaks. Correct any leaks found.

6. Open shutoff valve. Your outfit is ready for use.

TOO MUCH AIR PRESSURE CAUSES A HAZARD-

OUS RISK OF BURSTING.

CHECK THE

MANUFACTURERIS MAXIMUM PRESSURE RAT-

ING FOB AIR TOOLS AND ACCESSORIES.

THE

REGULATOR OUTLET PRESSURE MUST NEVER

EXCEED THE MAXIMUM PRESSURE RATING. ON

MODELS HAVING ONLY A SHUT-OFF VALVE, YOU

MUST INSTALL A REGULATOR BEFORE USING

ACCESSORIES RATED AT LESS THAN 125 PSlG.

Compressed air frem the outfit may contain water condensation and oil mist. Do not spray untiltered air at an item that could be damaged by

moisture. Some air operated tools or devices may

require filtered air. Read instructions for the air tool or device.

When You Are Finished:

7. Set the pressure switch lever to "OFF".

8. Close the shutoff valve.

9. Remove the air tool or accessory.

10. Open the shutoff valve and allow the air to slowly bleed from the tank. Close shutoff valve when tank pressure is approximately 20 PSI.

DRAIN TANK DAILY. WATER WILL CONDENSE IN

THE AIR TANK. IF NOT DRAINED, WATER WILL

CORRODE AND WEAKEN AIR TANK, CAUSING A

RISK OF AIR TANK RUPTURE.

11. With tank pressure at approximately 20 PSI, open the drain cock and allow moisture to drain.

NOTE

If the drain cockvalve is plugged, release all air

pressure. The valve can then be removed, cleaned

and reinstalled.

12.After the water has been drained, close the drain cock.

The air compressor can now be stored.

MAINTENANCE

UNIT CYCLES AUTOMATICALLY WHEN POWER

IS ON. DURING MAINTENANCE, YOU COULD BE

EXPOSED TO VOLTAGE SOURCES, COM-

PRESSED AIR OR MOVING PARTS. PERSONAL

INJURIES CAN OCCUR. UNPLUG THE UNIT AND

BLEED OFF ALL AIR TANK PRESSURE BEFORE

DOING ANY MAINTENANCE OR REPAIR. NEVER

OPERATE THE UNIT WITH THE BELT GUARD

REMOVED.

A dirty air filter will not allow the compressor to operate at full capacity. Before you use the compressor, check the air filter to be sure it is clean.

If it is dirty, replace it with a new filter. On some models, the filter may be removed by using a pair of needle nosed pliers or a screwdriver. Pull or pry out the old filter. Push in the new air filter. Other models require removal of the belt guard and/ or filter retainer.

Oil - Checking and Changing

To ensure efficient operation and longer life of the air com- pressor outfit, e routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will depend upon the hours of operation and the working environment. Compressor outfits in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks. Lubricate compressor motor (if required) according to manufectursr's instructions, which are attached to your motor.

Routine Maintenance Schedule

Daily:

1. Check oil level. Add if necessary.

2. Drain water from the air tank, any moisture separators or transformers,

3. Check for any unusual noise and/or vibration.

4. Manually check all safety valves to make sure they are operating properly.

5. Inspect for oil leaks and repair any leaks found.

6. Inspect air filter, replace if necessary.

Every 40 Hours of Operation:

1. Clean and inspect the air intake filter; replace if necesseary.

2. inspect condition of drive belt; replace if necessary.

Every 100 Hours of Operation:

f. Drainand refillcompressor crankcase with 16 fluid ounces

(473.2 ml) of clean compressor or Castrol Heavy Duty 30 weight.

2. Incrsase frequency of oil changes if humidity or opersting conditions are extreme.

Every 160 Hours of Operation:

1. Check drive belt tension; adjust if necessary. (Refer to

SERVICE INSTRUCTIONS in this manual.)

2, inspect air lines and fittings for leaks; correct as neces- sary,

3. Check the alignment of the motor pulley to the flywheel.

If necessary, align to within 1/32 inch on centerline.

Each Year of Operation or if a Problem is Suspected:

Check condition of air compressor pump intake and exhaust

valves. Replace if damaged or worn out.

SERVICE INSTRUCTIONS

Air Filter - Inspection and Replacement

Overfilling with oil will cause premature compressor failure. Do not overfill.

Check oil level in the crankcase daily. Remove the oil fill olua.

The oil level should be even with the too of the fill hole and must not be allowed to be lower than 3/8" from the toe (6 threads)

It is recommended that the oil be changed after every 100 hours of operation. To drain the oil, remove the oil drain plug and collect the oil in a suitable container. Be sure to replace the plug securely before adding new oil. Use a compressor oil such as Castrol Heavy Duty 30 weight. Crankcase oil capacity is 16 fluid ounces (473.2 ml).

CheckValve - Inspection and Replacement

Remove and inspect the check valve at least once a year or more often if the compressor is heavily used. Moisture and

other contaminants in the hot compressed air will cause an accumulation of a carbon-like residue on the working parts.

If the valve has heavy carbon build-up, it should be replaced.

Use the following procedure to inspect, clean or replace the check valve.

1. Unplug compressor. Release air pressure from the air tank.

2. Loosen the top and bottom tube nuts and remove the outlet tube.

3. Unscrew the check valve (turn counterclockwise) using socket wrench (7/8").

4. Checkthatthevalvedisc moves freelyandthatthespring holds the disc in the upper, closed position. The check valve may be cleaned with a solvent.

5. Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise). Do not overtighten.

6. Replace the outlet tube and tighten top and bottom tube nuts.

Safety Valve - Inspection and Replacement

IF THE SAFETY VALVE DOES NOT WORK PROP-

ERLY, OVER-PRESSURIZATION MAY OCCUR

CAUSING AIR TANK RUPTURE OR EXPLOSION.

DAILY PULL THE RING ON THE SAFETY VALVE

TO MAKE SURE THAT THE SAFETY VALVE OP-

ERATES FREELY. IF THE VALVE IS STUCK OR

DOES NOT OPERATE SMOOTHLY, IT MUST BE

REPLACED WITH A VALVE HAVING THE SAME

PRESSURE RATING.

Keep the air filter cleon at oil times. Do not operate the compressor with the air filter removed.

9

Belt - Replacement

SERIOUS INJURY OR DAMAGE MAY OCCUR IF

PARTS OF THE BODY OR LOOSE ITEMS GET

CAUGHT IN MOVING PARTS. NEVER OPERATE

THE OUTFIT WITH THE BELT GUARD REMOVED.

THE BELT GUARD SHOULD BE REMOVED ONLY

WHEN THE COMPRESSOR IS UNPLUGGED.

Belt Guard - Removal and Installation

(Refer to Outfit Parts Listing, ff required.)

1. Move the "ON/AUTO-OFF" lever to the "OFF" position.

Unplug the compressor.

Release all air tank pressure.

2. On one-piece belt guards, remove the two beltguard screws on the bottom front of the outfit.

3. On two-peice belt guards, remove the front of the belt guard by disengaging the snaps.

Insert a flat bladed screwdriver at each snap location and pry the beltguard apart.

Replace Belt

1. Unplug compressor.

2. Remove (one-piece) beltguard, or front of (two-piece) beltguard as described above.

NOTE

Loosen the wing nut at the hold down plate. The motor can be tilted to allow for easy removal or installation of the belt.

3. Remove belt and replace.

NOTE

The belt must be centered over the grooves on the flywheel and motor pulley.

Adjust Belt Tension

Adjust belt tension by tightening the wing nut until it makes

contact with the washer, plus one additional turn.

Pressure Switch - Replacement

NOTE

If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when:

1. The motor does not get up to full power or speed.

2. Fuses blow out when the motor is started.

3. Lights dim when motor is started, and re main dim while it is running.

Pulley and Flywheel - Alignment

The compressor flywheel and motor pulley grooves must be

in-line within 1/32" to assure belt alignment within sheave grooves. To check alignment, unplug compressor and remove the beltguard. Place a straight edge against the out-

side of the flywheel and measure the distance from it to the

nearest groove. Alignment is achieved when the other end of the straight edge is within 1/32" of the measured dimension

at the pulley grooves.

Servicing Intake and Exhaust Valves

The intake and exhaust valves as well as the valve plates and cylinder head will, over a period of time, accumulate a residue of carbon-like material on their surfaces. The material will decrease the efficiency of the compressor. These compo-

nents should be inspected whenever a problem is suspected

and cleaned or replaced with new parts. Refer to "Outfit

PartsListing", if required. Use the following procedure to

inspect the parts.

1. Unplug compressor and relieve all air pressure from the air tank.

2. Disconnect the pressure release and outlet lines from the air compressor.

3. Remove the hardware securing the cylinder head and remove the cylinder head and valve plate.
