may not be used if option C is selected.
E. 1-1/2" Spacer Set (P/N 3097-250-000)
  InsomeinstancestheLadderAccessSystemsmustberaiseduptoaccommodateextra-wide
 ladders.Whenthisoccurs,asetoffour1-1/2"highspacerswillberequired(item57,page15)for
 propermountingoftheladders.Requiredwheneverthe27"longchannel(item54,page15)isneeded
 (seeChart3,page18).
F. Model LAS-LGK
  LadderGuardKitcontainsonetubeofepoxyandtwostainlesssteelguards.Theguardsmaybe
 attachedtotheladderrungstopreventwearandpossibledamageastheresultofthelockinghandle's
 contactwiththerung(seeFigure30,page39).
G. Model LLAS-MLS or Model LLAS-BHM-MLS
  TheManualLockingSystem(Figure24,page33)providesapositivemeansofretainingthe
 ladders.ThebasecastingfortheLASSystemwaschangedtoaddanewhighercentersectionto
 accommodatealockingsystem.WestartedshippingLASSystemswiththenewbasecastingon
 March23,1998.LAS-BHMSystemshavebeenusinganewbasecastingsinceSeptember16,1998.
 Thelockmustbede-activatedpriortooperatingtheelectricalcontrol.Thisisdonebypullingoutward
 onthestrap(item99,page33)orpushingbackonthehandle(item77,page33).
H. Model LLAS-ELS or Model LLAS-BHM-ELS
  TheElectricLockingSystem(Figure27,page36)isactivatedbypressingdownontheoperating
 switchallowingthesmallelectricactuatorstoopenthelockingmechanisms.Afteramomentarydelay,
 themainelectricactuatorslowertheSystem.Theelectriclockingsystemmayalsobeoperated
 manually(seepage36).

IV. GENERAL INSTALLATION INFORMATION
 TheLadderAccessSystemwasdesignedforladdersmeetingthecurrentNFPA1931standard.Systems
accommodatemostladdercombinations.However,forladdersover35feetorwithtormentorpoles,contact
ZiamaticCorp.toascertainiftheymaybeusedwithanAccessSystem.Combinations(seepage18)36,44,53,
63,72,80,126,128,129,130,132,133,144,152,154,157,158,and159requireladdermountsinexcessof
12 inches. Some of these combinations may be accommodated by adding spacers behind the ladder mount and
retainerhandlesupport,butthisincreasesthemountingdepthandtheladdersmayprotrudeexcessivelybeyond
thesideofthevehicle.Wedonotrecommendmountingoftheseladders.
Note: The weight of ladders and/or hard sleeves may not exceed 300 pounds with any of the Lad-
der Access Systems. We recommend the manual or electric locking systems (see pages 33 through 38) be
used whenever a hard sleeve tray is mounted over the LAS or HSS System or apparatus routinely navi-
gates rough/uneven terrain.
A. Mounting Points
  TheLadderAccessdevicesshouldbeplacedsymetricallyinreferencetotheladder.Thesame
 numberofrungsshouldextendpasteachladdersupport(page23).Thiswillensurethatbothunitsare
 liftingapproximatelythesameweight(ifthisisnotpossible,contactZiamaticCorp.).Boltholeshave
 beenprovidedonboththeverticalandhorizontalmountingsurfaces.Althoughthedevicemaybe
 securelymountedfromthehorizontalsurfaceonly,itisagreatadvantagetobeabletousemounting
 boltsontheverticalsurfaceaswell.One-halfinchthickbackingplatesshouldbeusedifusingonly
 verticalorhorizontalholesetsformounting(seeSectionV.A.,lastparagraph).BulkHeadMountunits
 musthavebackingplatesandcanonlybemountedtoaverticalsurface.
  Allboltsshouldhavereinforcementstructureaddedunderneaththemountingsurfacewhere
 possible.Channelorrectangulartubeshouldbeusedinsteadofatplateasreinforcement.If
 aluminumplateisused,itshouldbe1/2"thick(seepage21).
B. Electrical Circuit
  Thecontrolswitchshouldbeamomentarydouble-poledouble-throwexterior30ampswitch.We
 provideaswitchwitheachsystem.Itshouldbeplacedinsuchapositionthattheoperatorhasfullview
 oftheQUIC-LIFTSystemandpersonnelthatmightcomeincontactwithit.Usingwiresofequal
 lengthbetweenpowersourceandactuatorswillhelptokeeptheactuatorsrunninginsynchronization
 (seepage22forwiringdiagrams).
-4-

B. Electrical Circuit (continued)
  Several"LockOut"circuitsmaybeconsideredtopreventaccidentsfromoccurring.Anideal"Lock
 Out"systemwouldonlypermitoperationwhentheignitionswitchison,thetransmissionisinpark,and
any obstructing compartment doors are shut. Because of the higher amperage required to operate the
 QUIC-LIFTSystem,aseparate"LockOut"circuitshouldbeused(seeelectricaldiagramsonpage22).
 The"LockOut"circuitshouldbeseparatedfromtheQUIC-LIFTSystemcircuitbyarelay.Thiswill
 preventdamagetotheexistingwiringsystem.TheQUIC-LIFTSystemcircuitshouldbeprotectedbya
 30ampfuse.
  NFPA1901-96standardrequiresashinglightstobeprovided,facingfrontandrearofthe
 apparatus.LightsmustashwhenevertheSystemisoutofthestoredposition.Theashinglightkit
 (modelLAS-FLK)wasaddedtoallSystemsbeginningJanuary1,1997(seepages29&30).Priorto
 that,weprovidedanaudio-visualalarmandrelay.Theaudiovisualalarmmaystillbeorderedasan
 option(seemodelAVA,P/N8047-125-000incatalog).
Note: 24 volt systems do not include a Flashing Light Kit.
C. Synchronization of Actuators
  Asnotedunder"TroubleShooting"(SectionVI.C.)allelectricactuatorsaretimed,underload,and
 thetimesarerecorded.Ifyouexperienceanyproblemsassociatedwiththeelectricactuators,wewill
 requiretheserialnumberoffofyourdevice(seepages15and17forlocationofserialnumber).
  ItisimportanttotheoperationoftheQUIC-LIFTSystemthattheactuatorsworkinsynchro-
 nization.Theactuatorsmaybeoutofsyncaconsiderableamountbeforebindingoccurs,however,
 reducingtheoccurenceofthiswillincreasethelifeoftheactuatorsandpreventdamageorweartothe
 ladders.Keepingtheloadevenlydistributedonthetwodeviceswillhelptokeeptheactuators
 runninginsynchronization(Figure9,page23).
Do not permit personnel to hang, sit or stand on ladders or hose while stored on the QUIC
LIFT System.Iftheunitisoverloaded,theinternalclutchwillslipandpreventdamagetothe
actuators.
  Whentheoperatorraisesorlowerstheunit,heshouldletitrununtilhehearsbothclutchesstartto
 slipsothattheactuatorsre-synchronizeandarereadytorunintheoppositedirection.
  WehaveextensivelytestedourQUIC-LIFTSystemandhavefoundthenormallifetobeinexcess
 of5,000cycleswithoutfailure.Withreasonablecareandmaintenance,yourQUIC-LIFTSystemshould
 giveyoumanyyearsofexcellentservice.

V. INSTALLING THE LADDER ACCESS SYSTEM
A. Preparation for Mounting
Check both units to verify they have matching serial numbers.
  Planandlayouttheentireinstallationbeforemakinganycutsordrillingholesinthebodyofthe
 reapparatus.Thiswillkeep"outofservice"timetoaminimumandalsohelptominimizemistakes.
 SeeElectricalSystem(SectionB,page7)beforeanyholesaredrilledintotheapparatus.
  Laythetwounitsontheshelfoftheapparatustothatyoucanseewhereholeswillberequiredfor
 themountingbolts.Thereshouldbesufcientlysizedatsurfaceunderneaththemountingholes,free
 ofseamsandobstructionswheretheboltswillpassthrough.Raisetheladdersnearthetwounitsto
 determinewheretheywilllaywheninstalled.Theladdersmustbeevenlysupportedbyeachunit(the
 samenumberofrungsshouldextendontheoutersideofeachladdersupport).
  Whentheladderisraisedandloweredinthisposition,itshouldclearprotrudingobjectsonthe
 apparatussuchasemergencylights,handrails,etc.Makesurethatwhentheladdersareintheup
position they do not obstruct cross lays or hose reels.
  Measurethe"resting"depthofyourladdercombinationtodeterminehowfaryourladderswill
 protrudeoutfromthehosebedwall(adddepthof6"fortheretractedLASSystem).Intheeventthat
 theactuatorretainercasting(item48,page15)orinnerarmcasting(item2,page15)comeintocontact
 withthestiffeningribatthetopofthehosebed,youmayhavetonotchoutthestiffeningribtorecess
 thedevice(seepage21).Intheeventthatthestiffeningribisnotched,theexposedmetalsurfaces
 shouldbepaintedandcoveredwithanedgeguardmaterial.Inaddition,andinparticular,ifthe
 stiffeningribisnotched,youmaywishtoaddabackingplate(page21)ontheinsidesurfaceofthehose
 bedwall.Theplatewillreinforcethehosebedwallandprovideagoodmountingsupportforthe
 QUIC-LIFTSystem.Theedgesshouldberoundedoff,onthesidenexttothehose,andatheadbolts
should be used to mount the plate.
  Bolts3/8"orlargershouldbeusedtomountthebasecastingstothereapparatus.Whenthebases
 willonlybemountedtothehosebedwalloronlymountedtotheshelfdeck,1/2"boltsshouldbeused
 withsubstantialbackingplates(page21)andsupports.IfyouareinstallingtheQUIC-LIFTdevicesto
 onlyonesurface,wesuggestyoucontactoneofourtechniciansbeforebeginning.

B. Electrical System
  Nowthatyouaresureofyourmountingposition,youmaybegintolayoutyourelectricalwiring
 (pages22,29,37and38).Atthistime,itisagoodideatoremovetheunitsfromtheshelfand"C"
 clampthemtoatablesothattheunitswillswingoutawayfromthetablewhenlowered.Unitsshould
 bemountedthesamedistancebackfromedgeoftableastheywouldbeontheshelfofyourapparatus.
 Besurethetableissecuredbyaddingacounterweighttotheothersidebeforeloweringtheunits.Place
 laddersontotheladdermountcastings(item7,page15)justastheywillbestoredontheapparatus.
 Determinewherewirescanberunsotheywillnotbevisiblefromtheoutsideoftheapparatus.We
recommend all electrical connections be soldered as this method is superior to crimp connections.
 Measuretherequiredrunlengthsofeachwire(seepage22forproperwirediameter).
  Makeupawiringharnessusingwireslongerthantherequiredrunlengths.Temporarilymakeall
 wireconnectionssoyoucantestthesystem.Withthetableproperlysecured,youshouldbeableto
 operatetheunitswiththeladdersorhardsleevesattached.Besuretheladderswillcleartheedgeofthe
 tablebeforedrillinganyholesintheapparatus.Thewiringdiagramfortheashinglightsmaybefound
on page 29.
C. Mounting Suggestions
  A"WARNING"label(partnumber3097-105-149,item49,page14)issuppliedwitheach
 QUIC-LIFTSystem.Thepressuresensitivelabelmustbemountedbytheelectricalcontrolswitch.All
 apparatusoperatorsmustbeinstructedtokeepareainfrontofladdersclearofpersonnelwhenthe
 QUIC-LIFTSystemisbeingraisedorlowered.
  Beforestartingtheinstallation,youshouldmakesureyouhaveallnecessarytoolsandmaterials.
 Thisshouldincludematchingtouch-uppaint,edgetrim(forcutouts),fenderprotectorclothsand
 removabletape(toprotectpaint),necessaryhardware,wireconnectors,cableties,burrremover,vacuum
 cleaner(formetallings),edgeguards(forwiring),drills,drillgun,wrenches,stepladders,etc.Besure
 toremovethehosefromthehosebed.
  Followingthesesimpleinstructionsshouldmakeyourinstallationeasyandprofessional.

VI. TROUBLE SHOOTING
 Allunitsaretestedafternalassemblytoensureproperoperationandadjustment.Nofurther
adjustmentsshouldberequiredunlessexcessvibrationisnoted(seeVI.D.,page9).
A. Actuator "Creeping Down"
  AnindicatorlightmaybeinstalledinthecabofyourvehicletowarnthedriverwhentheSystemis
 outofthestoredposition.Ifthislightcomesonwhilethevehicleisinmotion,itmaybeanindicator
 thatoneoftheelectricactuatorsis"creepingdown".Theactuatorwillnotdropsuddenlybutthedriver
 shouldkeepaneyeontheSystemuntilhereacheshisdestination.Thentheswitchmaybeactivatedto
retract the System to the stored position.
  Undercertainroadconditions,thefrequencyofvibrationsmaycausethefrictionbrakewithinthe
 electricactuatortoslip.Thisinturnmayallowthemotortoturnandthewormgeartoretractor"back
 drive".Thesameproblemmayoccurwhenahardsleeveismountedabovetheladdersand/orhard
 sleeves.
  IfyourSystem"creepsdown",wesuggestyouaddthemanuallockingsystem(Figure24,page33)
 orelectriclockingsystem(Figure27,page36)toyourSystem(seeIII.G.&H.,page3).
B. Ladder Wider Than Ladder Support
  Iftheproperladdercombinationisspeciedatthetimeofordering,thisproblemshouldnotoccur.
 Thestandardsupportchannel(item54,page15)is25-1/4"long.Wecanalsoprovidealongersupport
 channel(partnumber3097-105-155)whichis27"long.SeeChart3,page18,forcombinations
 requiringthe27"longchannel.Spacerset(partnumber3097-250-000)mustbeorderedwiththese
combinations.
C. One Actuator Running Two Or More Seconds Slower Than The Other
  Allactuatorsaretimed,underload,atthefactorywiththetimesrecorded.Wematchupelectric
 actuatorswithasclosetoequaltimesaspossiblewhenassemblingaQUIC-LIFTSystem.Whenone
 actuatorisrunningmorethantwosecondsbehindtheother,itisnormallyduetosometypeof
 resistanceinthewiringsystem.Checkallwireconnectionstomakesuretheyaresecure.Makesureto
 ratchetbothactuatorsattheendofeachupanddowncycle.Iftheyarestillgreatlyoutofsync,after
 checkingthewiringandratchetingunitsattheendofeachcycle,youmayswitchtheactuatorsto
 conrmiftheproblemisinthewiringsystem.Afterremovingtheladders,removethenut/bolt
 assembly(items10,16and42,page15)toremovetheactuator.Switchthetwoactuatorsand
 reassemble.Iftherearunitactuatorwasoriginallyrunningslowerandthisunitisstillrunningslower
 thentheproblemisinthewiring.Iftheproblemswitchesfromrearunitactuatorrunningslowertofront
 unitrunningsloweraftertheswitch,thentheproblemmaybetheactuator.

D. Excess Vibration May Cause Failure Of One Or More Castings
  A"WARNING"label(partnumber3097-105-158,item58,page14)hasbeenattachedtoeachset
 ofcastings.If,afterinstallingtheSystemandladders,younoteexcessivemovementoftheladders
 whileoperatingthevehicle,checkthefollowing(referringtodrawingsonpages11&15andbillof
