OPERATION

DANGER:‐
Thistrailerisfittedwithapickupeyedesignedforusewithapick‐uphitch.Check
theeyecannotescapefromthetractorhitchasthedrawbarmayliftwhenthe
trailerisfullytipped.Ifthetraileristobehitchedtoaconventionalclevisdrawbar
asuitablebushshouldbeusedtoeliminateshockloadsonthetowingpin.

ConnectingtotheTractor
1. Connecttrailertotractorviathetractorpick‐uphitch.Ensurethehitchisproperly
engagedandlockedinposition.
2. Turnthetractoroff,applytheparkbrakeandremovekeyfromignition.
3. Ensurethebrakehoseandhydraulichosesareingoodconditionandtheprobesare
clean.Ifdirtydiptheprobeinparaffintocleanit.
4. Connectthehydraulicbrakestotheservicebrakevalve,onthetractor.
5. Connectthehydraulichosestothetractor.Thetippingcylinderrequiresasingleacting
spoolvalveandthereardoorcylinderadoubleactingspoolvalve.
6. Ensurealllightsarecleanandconnect7‐pinplug.

WARNING:‐
Ifusingonpublicroadslightguardsmustberemoved.

7. Connectthesecondarycoupling(ifapplicable).Asecondarycouplingisan
additionalcouplingtothetractorhookandtrailertowingeye.Thesecondary
couplingusuallyconsistsofasafetychainwhichensuresthatthetrailerremains
attachedtothetractoriftheprimarycouplingfailsorbecomesdetached.It
preventsthetrailersdrawbarfromtouchingthegroundandprovidessomelevel
ofsteering.Asecondarycouplingisnotneededifatrailerhasbeenequipped
withabreakawaysystemorairbrakesareinuse(seeoptionalextras).

WARNING:‐
ThesafetychainMUSTNOTbefittedtothetoplinkoranyotherhighpointonthe
tractorasthismaycausethetrailersdrawbartocomethroughthebackwindowofthe
tractorandseriouslyinjurethedriverordamagetotherearofthetractor.
NOTE:‐
Theminimumstrengthofthechainmustbeequaltothegrossweightofthe
trailerbeingdrawn.
Safetychainsmustbesecurelyattachedtoboththetractorshitchandthe
trailerdrawbar.
Safetychainsmustnotbedamaged,forexample,wornfromdraggingonthe
ground,stretchedorkinked.
Theslackinthechainshouldonlybeenoughtoletthetractorturn.

8. Thedrawbarstandcanberemovedifnecessaryandstoredonthebracketprovided.
9. Releasethetrailerparkbrake.Toreleasetheparkbrakepushithardtowardsthebody
ofthetrailer,thiswilldisengagethelatch.Theremustbeenoughfreeplayinthecable

18
toallowthesuspension(iffitted)tomovefullywithoutapplyingthebrakes.Ifthepark
brakeisreleasedfrombeingfullyontherewillusuallybeenoughspringbackinthe
cable.However,toensurethereisenoughfreeplaythelevershouldbeleftinthe
rearwardpositiontoallowmorecabletounwindifnecessary.Toapplyoperatethe
ratchetuntilthecablesaretight.
10. Checkthatallfunctionsareoperational,particularlythebrakes.
11. Beforedrivingofforcarryingoutanyothertaskensurethesurroundingareaisclearof
bystanders.

OperationoftheHydraulicDoor

DANGER:
ALWAYScheckthereisnoloosematerialbetweenthechassisandthedoorpriorto
tipping.
ALWAYSensurethereisnoonebehindornearthedoorbeforeopening/closing.
NEVERreachintothedangerzonebetweentherearchassisandthedoorwithoutthe
proppinsfullyengaged.

Toraisethehydraulicdoor,operatethespoolvalveuntilthedoorisupright.Tolowerthe
door,movetheleverintheoppositedirection.Whenloadingequipmentfromtherearthe
doormustbefullyopen.

ProcedureforSafelyClearingaBlockageattheHydraulicDoor
Whenloadingthetrailer,astoneorotheritemmayfallbehindthedoorpreventingitfrom
opening.Ifthisisnoticedbeforethetraileristipped:‐
1. Applythetractorparkbrake,stopthetractorandremovethekey.
2. Engagebothdoorlockingpins.
3. Removetheitem.


Ifthetrailerhasbeentippedandtheitempreventsthedoorfromfullyopening:‐


19
1. Fullylowerthetrailer
2. Fullyraisethedoor
3. Applythetractorparkbrake,stopthetractorandremovethekey.
4. Engagebothdoorlockingpins.
5. Removetheitem.

DrivingonPublicRoads
Thetrailerisdesignedformaximumspeedof40kph(25mph),unlessstatedotherwiseon
thespeeddecalfittedtothetrailer.Useatover40kph(25mph)intheUKrequireshigh
speedaxles,suspension,airbrakes,loadsensing,automaticslackadjustersandABS.
Regulationsinothercountriesmayvary.Alwayscomplywithlocalandnationalregulations
inthecountryofuse.

DANGER:‐
SinglelinehydraulicbreakingisNOTlegalforuseonUKroadsabove40kph(25mph).

IntheUKatspeedsupto15kphthetrailermustbefittedwithanumberplateissuedtothe


DANGER:‐
Nevercarrypassengersonthetrailer,eitheronthepublicroadandorprivateproperty.

Loading
Theunladenweight,grossweight,drawbarweightandaxleweightsofthetrailerare
stampedontotheserialplate(locatedonthefrontnearsideofthetrailer).YoumustNEVER
exceedtheseloadratings.

Regulationsmeanitisnotalwayspossibletofullyloadthetrailerwhenusingonpublic
roads.IntheUK,themaximumcombinationweight(tractorandtrailer)is31000kgandthe
maximumladentrailerweightis18290kg.

Thefollowingtableisaroughguidefortypicalmaterials.Ifcarryingothermaterial,you
shouldcheckitsdensitytopreventoverloading.

Tipping

DANGER:‐
Alwayscheckforbystanders,particularlyintheunloadingzonebeforetipping.
Alwayscheckthereisnoloosematerialbetweenthechassisanddoorpriortotipping.
Alwaysfullyopenthereardoorbeforetipping.
Alwaystiponstable,flatground.
Nevertipacrossslopes.
Nevertipwhentherearehighcrosswinds.
Nevertipatrailerunlessitiscorrectlyhitchedtoasuitabletractor.
Nevertipbelowornearoverheadpowerlinesandmaintainasafedistancefrompower
linestopreventelectricalarcing.Checkdecalontrailerformaximumtippingheight.
Neverdisconnectthehydraulicfunctionsofthetrailerwhilethebodyisraised.
Thefailuretopreventorclearstickingloadsorblockagesduringtippingcancausethe
trailertotip‐over.

Toensureoperatorssafetyraising/loweringshouldtakeplace,fromthedriver’sseat,
withthecontrolheldonandshouldstopwhenthecontrolisreleased.Totipthe
trailer:‐
1. Movetherelevantspoolinthetractortoopenthereardoor.
2. Whenthereardoorisopenfullytipthetrailerbody.Donotmoveforwardor
backwardswiththetrailerintheraisedpositiontopreventoverturningor
hittinganoverheadpowerline.Ifthisisnecessarytocompletelyemptythe
