450P AUTOMATIC PORTABLE COMPRESSOR

OPERATING INSTRUCTIONS:

Pleasereadandfollowtheoperatinginstructionscarefullytoassurethatyouwillenjoythe
convenienceandbestuseoutofyouraircompressor.

1.AlwaysoperatethecompressorATORBELOWTHEMAXIMUMPRESSURERATINGofthe
 compressor.RefertoSpecicationssectionofthismanual.

2.AlwaysOBSERVETHEMAXIMUMDUTYCYCLEoftheaircompressor.RefertoSpecications
 sectionofthismanualfordetails.Operationsexceedingmaximumpressureratingsandorduty

cycle will result in damage to air compressor.

3.YouraircompressorisequippedwithanAUTOMATICTHERMALOVERLOADPROTECTOR.
 Thisfeatureisdesignedtoprotecttheaircompressorfromover-heatingandcausingpermanent
 damagetoyouraircompressor.Thethermaloverloadprotectorwillautomaticallycutoffpower
 toaircompressorshouldinternaloperatingtemperatureoftheaircompressorriseabovesafe
 levelsduringexcessiveuse.

4.Shouldyourcompressorshutoffsuddenlyafterextendeduse,donotattempttorestartair
 compressor.TurnON/OFFswitchofaircompressortotheOFFposition.Theautomaticthermal
 overloadprotectorwillautomaticallyresetwheninternaltemperatureoftheaircompressordrops
 belowsafelevel.Afterallowingaircompressortocooloffforabout30minutes,youcansafely

resume use of the air compressor by turning on the air compressor.

5.Foryourconvenience,andtoprotecttheaircompressorfromover-pressureoperationthatcan
cause permanent damage to the unit - this compressor is equipped with built-in pressure switch

 withafactorysetcut-onpressureof120PSI(±5%)andafactorysetcut-offpressureof
 145PSI(±5%).Duringinationoftirepressuresbetween115PSIto145PSI,ifyoustopination,

the compressor may not restart. This is completely normal, since inline pressure is greater than
cut-on pressure of the pressure switch and less than cut-off pressure of the pressure switch.

 Torestartcompressor,deatetirepressuretobelow115PSI,reconnecttirechucktotirevalve
 stemandresumetireination.

6.Pleasenotethatyoumayexperienceaslightdelayofthecompressor’smotorstartingwhenthe
 ON/OFFswitchisturnedonwhilecompressorispressurized(whenthereispressureintheline
 thatthecompressorisconnectedto).Thisisanormaldelayedreaction,notaCompressor
 ON/OFFswitchmalfunction.

7.Itisstronglyrecommendedthatyoukeepthevehicle’senginerunningwhileusingtheair
 compressortopreventdischargeofyourvehicle’sbattery.

8.ONLYOPERATETHEAIRCOMPRESSORINWELLVENTILATEDAREAS.
 Compressorperformanceisenhancedwhenoperatingcompressorwithvehicleenginerunning.

IMPORTANT:Enginemustberunningwhileusingthiscompressor.
Beforeattachingaircompressorpowerclampstoyourvehicle’sbatteryterminals,checktomake
surethattheON\/OFFswitchofyourcompressorisintheOFFposition.AttachthePositive(+)
batteryclamp(Red)tothePositiveterminalofthebatteryandtheNegative(-)batteryclamp(Black)
totheNegativeterminalofthebattery.Alwayskeepyourvehicle’senginerunningwhileoperating
compressortoavoiddrainingyourvehicle’sbattery.

CAUTION:YourPortableAirCompressorisMoistureandDustResistant,butNOTWATERORDUST
PROOF.Neverplacecompressorinsoftsandwhilerunningthecompressor.Vibrationfromthe

compressor will cause the compressor to settle into soft sand, resulting in compressor drawing in

foreignparticles.Neverexposecompressortowaterwhilerunningthecompressor.

USER MANUAL

450P AUTOMATIC PORTABLE COMPRESSOR

OPERATING INSTRUCTIONS (cont’d):

This air compressor comes with 1/4” quick connect stud. An extension coil hose and a tire

ination gun are also included with your compressor. Each end of the extension coil hose is
equipped with a 1/4” quick connect coupler. The tire ination gun comes with a 1/4” quick
connect stud, pressure gauge, rubber hose, bleeder valve and tire chuck. Attach one end of
the extension coil hose to the stud on your compressor and the other end to the stud on the
tire gun kit. The tire gun kit can be used for both airing up and airing down. Please familiarize
yourself with the following functions of this versatile air tool:

TIRE INFLATION:

1.Attachoneendoftheextensioncoilhosetothecompressorandtheotherendtothetiregunkit.

2.Pushthetirechuck,withtheleverintheuprightposition,downoverthetirevalvestemandthen
 pushtheleverdowntothehorizontalpositiontolockinplace.

3.Turncompressorswitchonandholddownthetriggeronthetiregunkittobeginination.

4. When desired pressure is reached, release the trigger and turn power switch on compressor off.

NOTE:Toreleaseexcesspressure,turnoffcompressoranddisconnecthosefromcompressor.
Withthetireinationgunstillconnectedtotheotherendofthecoilhose,pulltriggeronthetire
inationguntoreleaseexcesspressure.

CAUTION:Toavoidoverination,neverexceedrecommendedpressureonarticlestobeinated.
Burstingcancauseseriousinjury.

NOTE:Youraircompressorisequippedwithapressureswitch(cutinat120psi,cutoutat145psi).
Thisfeatureisdesignedtoprotecttheaircompressorfromover-pressurecausingpermanent

damage to your air compressor. The pressure switch automatically turns off the motor when the

internalpressureoftheaircompressorreachesthefactoryset“cut-out”pressure(145psi)and
restartswhentheinternalpressuredropsbelow120psi.

TIRE DEFLATION:

1.Pushthetirechuck(withtheleverintheuprightposition)downoverthetirevalvestemandthen
 pushtheleverdowntothehorizontalpositiontolockinplace.

2.Pressthebleedervalvebuttononthetiregunkittodecreasetirepressure.

3.Whendesiredpressureisreached,releasethebleedervalvebuttontohaltdeation.

IMPORTANT:Makesurecompressorsitsuprightwhileoperatingcompressor.Donotoperate
compressorinanyotherposition.Avoidtuggingatcompressortomoveit.Instead,move
compressortothesamesideofvehicleastiresthatarebeingairedup.

AlwaysmakesurethePortableCompressor’spowercordisuncoiledandfullyextended
whenusingyouraircompressortoavoidoverheatingthepowercord.

INLINE PRESSURE GAUGE:

1.Thepressuregaugeontheinationgunprovidesconvenienttirepressuremonitoringwhenairing
 upordown(notairowofthecompressor).Thiseliminatesswitchingbackandforthbetweena

tire chuck and a tire pressure gauge.

2.Pleasenotethatduringinationanddeation,duetoairvelocity,pressuregaugecannotprovide
 accuratepressurereadings.Releaseleveronthetireinationgunduringinationtocheck

tire air pressure.

NOTE:Toreleaseexcesspressure,turnoffcompressoranddisconnecthosefromcompressor.
Withthetireinationgunstillconnectedtotheotherendofthecoilhose,pulltriggeronthetire
inationguntoreleaseexcesspressure.

SAFETY PRECAUTIONS:

1.Alwaysinatetirestomanufacturer’srecommendedtirepressures.Exerciseextremecaution
 whendrivingwithaired-downtires.Reinatetiresbeforehigh-speedroadwaytravel.

2.Neverexceed20M.P.H.whendrivingwithpartiallyinatedtires.

3.Nevermakesharpturnswhiledrivingwithreducedtirepressure.

4.Re-inatetiresbeforehighspeedtravelingontoroadways.

5.Useheat-resistant,minimum200PSI-ratedworkingpressureextensionhose.
 Donotuseaftermarkethoseswithlessthan200PSIworkingpressure.Someaftermarkethoses

may not be suitable for use with this air compressor due to heat and pressure typically generated
by this type of air compressors.

CAUTION:Nevertouchtheaircompressororttingsconnectedtotheaircompressorotherthan
theON/OFFswitchwithbarehandsduringorimmediatelyafteruse.Theextensionhoseandttings
connectedextensionhosewillbecomeveryHOTduringandafteruse.Ifnecessary,wearheat
resistantglovestoremovehosefromthecompressorquickconnectstud.

MAINTENANCE & REPAIRS:

Youraircompressorisequippedwithpermanentlylubricated,maintenance-freemotor.
Nevertrytolubricatethecompressor.Regularlycleandustanddirtfromcompressorcoolingns
andmotorhousing.AllrepairsshouldbeperformedbyManufacturerorManufacturerauthorized
