HOW TO SET UP YOURUNIT
Location of the Air Compressor
Locate the air compressor in a clean,dry and well ventilated area. The aircompressor should be located atleast 12" away from the wall or otherobstructions that will interfere withthe flow of air. The air compressorpump and shroud are designed toallow for proper cooling. The ventila-tion openings on the compressor arenecessary to maintain proper operat-ing temperature. Do not place rags orother containers on or near these
openings,The air filter must be keptclear of obstructions which could
reduce air flow to the air compressor.
GROUNDING INSTRUCTIONS
RISK OF ELECTRI-CAL SHOCK. In
the event of a short circuit, ground-ing reduces the risk of shook byproviding an escape wire for theelectric current. This air compres-sor must be properly grounded.
The portable air compressor isequipped with a cord having agrounding wire with an appropriategrounding plug (see following illustra-tions). The plug must be used withan outlet that has been installed andgrounded in accordance with all localcodes and ordinances.
. The cord set and plug with thisunit contains a grounding pin.This plug MUST be used with agrounded outlet.
IMPORTANT: The outlet being usedmust be installed and grounded inaccordance with all local codes andordinances.
. Make sure the outlet being usedhas the same configuration asthe grounded plug. DO NOTUSE AN ADAPTER. See illustra-tion.
3. Inspect the plug and cord beforeeach use. Do not use if there are
_ Grounded/Outlets

signs of damage.
4. If these grounding instructionsare not completely understood,or if in doubt as to whether thecompressor is properly ground-ed, have the installation checkedby a qualified electrician.
_ IMPROPERGROUNDING CANRESULT IN ELECTRICAL SHOCK.
Do not modify the plug provided. Ifit does not fit the available outlet, acorrect outlet should be installedby a qualified electrician.
Repairs to the cord set or plugMUST be made by a qualified elec-trician,
11-ENG _24588
Extension Cords
Using extension cords is not recom-mended. The use of extension cords
will cause voltage to drop resulting in
power loss to the motor and over-heating.
Instead of using extension cordsattach extra air hoses to each other
starting at the air outlet.
If an extension cord must be used,be sure it is:
• a 3-wire extension cord that has
a 3-blade grounding plug, and a3-slot receptacle that will acceptthe plug on the product
- in good condition
• no longer than 50 feet
• 12 gauge (AWG) or larger. (Wiresize increases as gauge numberdecreases. 10 AWG and 8 AWG
may also be used. DO NOT USE14 OR 16 AWG.)
Voltage and Circuit Protection
Refer to the specification table for thevoltage and minimum branch circuitrequirements.
Certain air compressors can be oper-ated on a 15 amp circuit if the follow-
[ng conditions are met.
1. Voltage supply through branchcircuit is 15 amps.
2. Circuit is not used to supply any
other electrical needs (lights,appliances, etc.).
3. Extension cords comply withspecifications.
4. Circuit is equipped with a 15amp circuit breaker or 15 amptime delay fuse. NOTE: If com-
pressor is connected to a circuitprotected by fuses, use only timedelay fuses, Time delay fusesshould be marked "D" in Canadaand "T" in the US.
If any of the above conditions cannotbe met, or if operation of the com-pressor repeatedly causes interrup-
tion of the power, it may be neces-sary to operate it from a 20 amp cir-
cuit. It is not necessary to change thecord set.

Know Your Air Compressor
READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself withthe location of various controls and adjustments. Save this manual for futurereference.
Switch
Safety Valve
Description of OperationBecome familiar with these controls
before operating the unit.On/Auto/Off Switch: Turn this switchON to provide automatic power tothe pressure switch and OFF toremove power at the end of eachuse.
Pressure Switch: The pressureswitch automatically starts the motorwhen the air tank pressure dropsbelow the factory set "cut-in" pres-sure, it stops the motor when the airtank pressure reaches the factory set"cut-out" pressure.
Safety Valve: If the pressure switchdoes not shut off the air compressorat its "cut-out" pressure setting, thesafety valve will protect against highpressure by "popping out" at its fac-tory set pressure (slightly higher thanthe pressure switch "cut-out" setting),
Outlet Pressure Gauge: The outletpressure gauge indicates the air pres-sure available at the outlet side of theregulator. This pressure is controlledby the regulator and is always lessthan or equal to the tank pressure.
Tank Pressure Gauge: The tankpressure gauge indicates the reserveair pressure in the tank.
Regulator: Controls the air pressureshown on the outlet pressure gaugePull the knob out and turn clockwiseto increase pressure and counter-clockwise to decrease pressure.When the desired pressure is reachedpush knob in to lock in place.Drain Valve: The drain valve is locat-ed at the base of the air tank and isused to drain condensation at theend of each use.
Cooling System (not shown): Thiscompressor contains an advanceddesign cooling system. At the heartof this cooling system is an engi-neered fan. It is perfectly normal forthis fan to blow air through the ventholes in large amounts You knowthat the cooling system is workingwhen air is being expelled.
33-ENG D24588
Air Compressor Pump (not shown):Compresses air into the air tank.Working air is not available until thecompressor has raised the air tankpressure above that required at theair outlet.
Check Valve: When the air compres_sor is operating, the check valve is"open", allowing compressed air toenter the air tank. When the air com-pressor reaches "cut-out" pressure,the check valve "closes", allowing airpressure to remain inside the air tank.
If the overload protector shuts themotor off frequently, check for a pos-sible voltage problem, Low voltagecan also be suspected when:
1. The motor does not get up to full
power or speed.
2. Fuses blow out when startingthe motor; lights dim and remaindim when motor is started and is
running.
How to Use Your Unit
How to Stop:
1. Set the On/Auto/Off lever to
"OFF".
Pressure Release Valve: The pres-sure release valve located on the side
of the pressure switch, is designed toautomatically release compressed airfrom the compressor head and theoutlet tube when the air compressorreaches "cut-out" pressure or is shutoff. The pressure release valve allowsthe motor to restart freely. When themotor stops running, air will be heardescaping from this valve for a fewseconds. No air should be heard
leaking when the motor is running orafter the unit reaches "cut-out" pres-sure.
ReleaseValve
Motor Overload Protector: Themotor has an automatic reset thermaloverload protector. If the motor over-heats for any reason, the overloadprotector will shut off the motor. Themotor must be allowed to cool down
before restarting. The compressorwill automatically restart after themotor cools,
Before First Start-up
_ Serious damagemay result if the
following break-in instructions are
not closely followed.
This procedure is required before theair compressor is put into service and
when the check valve or a completecompressor pump has beenreplaced.
1. Make sure the On/Auto/Off lever
is in the "OFF" position.
NOTE; If quick connect is installed,pull coupler back until it clicks to provent air from escaping through thequick connect.
2. Plug the power cord into the cor-rect branch circuit receptacle,(Refer to Voltage and CircuitProtection paragraph in theInstallation section of this manu-
al .)
3. Open the drain valve fully (coun-terclockwise) to permit air toescape and prevent air pressurebuild up in the air tank during thebreak-in period.
NOTE; Always drain tank on a wash-able surface or in a suitable container
to prevent damaging or staining sur-faces.
D24588 14 ENG
4. Move the On/Auto/Off lever to
"ON/AUTO" position. The com-pressor will start.
5. Run the compressor for 15 min-utes. Make sure the drain valve is
open and there is minimal airpressure build-up in tank
6, After 15 minutes, close the drain
valve (clockwise). The air receiverwill fill to "cut-out" pressure andthe motor will stop.
The compressor is now ready for use,
Before Each Start-Up:
1. Place On/Auto/Off lever to"OFF".

.
Pull regulator knob out, turn
counterclockwise until it stops.Push knob in to lock in place.
Attach hose and accessories.
NOTE: The hose or accessory
will require a quick connect plugif the air outlet is equipped with a
quick connect.
Too much air pres-sure causes a haz-
ardous risk of bursting. Check themanufacturer's maximum pressurerating for air tools and accessories.The regulator outlet pressure mustnever exceed the maximum pres-sure rating,
How to Start:
1, Turn the On/Auto/Off lever to
"AUTO" and allow tank pressureto build. Motor will stop whentank pressure reaches "cut-out"pressure.
2. Pull the regulator knob out andturn clockwise to increase pres-sure. When the desired pressure
is reached push knob in to lockin place. The compressor isready for use.
NOTE: Always operate the air com-pressor in well-ventilated areas free

Before you store the air compressor,make sure you do the following:
1. Review the "Maintenance" sec-
tion on the preceding pages andperform scheduled maintenance
as necessary.
2. Set the On/Auto/Off lever to"OFF".
3. Turn the regulator counterclock-wise and set the outlet pressureto zero.
4 Remove the air tool or accesso-
ry.
5. Pull ring on safety valve allowingair to bleed from the tank until
tank pressure is approximately20 psi. Release safety valve ring,
6. Drain water from air tank byopening drain valve on bottom oftank.
Water will con-dense in the air
tank. If not drained, water will cor-rode and weaken the air tank caus-
ing a risk of air tank rupture.
7. After the water has been drained,close the drain or drain valve.
NOTE: .If drain valve is plugged,release all air pressure. The valvecan then be removed, cleaned, thenreinstalled.
8. Protect the electrical cord and air
hose from damage (such asbeing stepped on or run over).Wind them loosely around thecompressor handle. (If so
equipped)
Store the air compressor in a cleanand dry location.

Performing repairs may expose voltage sources, movingparts or compressed air sources, moving parts or com-
pressed air sources. Personal injury may occur. Prior to attempting anyrepairs, unplug the air compressor and bleed off all air tank air pressure.

at the pressure release valvewhen there is pressure in the
tank and the compressor isshut off. Replace checkvalve, Refer to the "To
Replace or Clean CheckValve" in the "Service and
Adjustment" section.
Contact a Trained ServiceTechnician,
Air tank must be replaced.Do not repair the leak.
Do not drill into, weld or
otherwise modify air tankor it will weaken. The tank
can rupture or explode.

PROBLEM
Pressure reading
on the regulatedpressure gaugedrops when anaccessory is
used.
Knocking Noise.
Compressor isnot supplyingenough air to
operate acces-sories.
Possible defect in safetyvalve.
Defective check valve,
Prolonged excessive use ofair.
Compressor is not largeenough for air requirement.
Hole in hose.
Check valve restricted.
Air leaks.
Restricted air intake filter
CORRECTION
If there is an excessive
amount of pressure dropwhen the accessory is used,adjust the regulator followingthe instructions in the
"Description of Operation"paragraph in the "OperationSection.
NOTE: Adjust the regulated3ressure under flow condi-
tions (while accessory is
bein 9 used).
Operate safety valve manual-ly by pulling on ring. If valvestill leaks, it should bereplaced.
Remove and clean, orreplace.
Decrease amount of air
usage.
Clean or replace air intake fil-ter. Do not operate the aircompressor with the filterremoved. Refer to the "Air
Filter" paragraph in the"Maintenance " section.
Check the accessory air
requirement. If it is higherthan the SCFM or pressuresupplied by your air com-#ressor, you need a largercompressor.
Check and replace ifrequired.
Remove and clean, or
replace.
Tighten fittings.
