GETTING STARTED - CHECKS BEFORE USE & HOSE SUPPORT BRACKET
1.3 CHECKS BEFORE USE
 Thesechecksshouldbecarriedoutduringinstallationandonafrequentandregularbasisthereafter.Ifthehoistisuseddailythenitis 
 recommendedthattheyarecarriedoutdailyasthecheckstakeonlyminutestocompleteandnotonlyhelpavoidrepairbillsbutsignicantly 
 reducethepossibilityofanaccidentordangerousoccurrence.Thoroughlyexaminetheequipmentpriortoinstallationtoensurethatno 
 damagehasoccurredduringtransit.HoistsandtrolleysshouldnotbealteredinanywaywithoutcontactingRedRoosterforclearance,asthis
 maya󰀨ectthecerticationoftheunit.
AIR SUPPLY CHECKS:
 ▪ Inletpressure:5to6bar(therewillbepressurelossesacrosstheairsetandonlonghoses)Thesupplypressureshouldnot 
  exceed7barasthismaya󰀨ecttheloadlimiter.
 ▪ Airow:Checkairowrequirementandminimumhosediameteralsocheckthatsmallborettingsarenotstranglingtheairow.
 ▪ Keepthelubricatortoppedupwithalightturbineoil(ISOVG3256).
 ▪ Theltershouldbecheckedregularlyandmanualunitsdrainedofwaterasrequired.
 ▪ THE AIR HOSE SHOULD BE SUPPORTED SO THAT THE WEIGHT OF HOSE IS NOT HANGING FROM THE AIR SET AND
`FITTINGS. THE AIR SET IS NOT DESIGNED TO SUPPORT THE WEIGHT OF THE HOSE. SEE PAGES 7 AND 12 IF A HOSE
SUPPORT BRACKET AND MANIFOLD IS FITTED TO THE HOIST.
 ▪ Theairsupplyshouldbecleanandrelativelydry.Wherethecompressorproducesalotofwateractionshouldbetakentoremove 
  theexcesswater.
 ▪ Checkairconnectionsizeandtypearecompatible.
 ▪ Checksecurityofairhoseconnection.
AIR SUPPLY CONNECTION:
 Everyinstallationisdi󰀨erent,sothecorrectmethodofsupportingtheairhoseshouldbereviewedwhileinstallingthehoist.Thisneedsto 
 takeintoaccounttheweightandsizeofthehose,obstructionsbothatdeckandhoistlevel,connections,operatingconditionsandanylikely 
movement of the hoist and air hose.
 Thettingsandlterlubricatorarenotdesignedtotaketheweightofthehose.
 Iftheairsupplyhoselengthisover10metresthehoseIDshouldbeincreasedtothenextsize.
AIR SUPPLY:
 Vanetypeairmotorsaredesignedtofunctionusingclean,dry,lubricatedair.Theinstallationofan‘inline’airserviceunitalthoughessential 
cannot in itself compensate for serious contamination in the air supply. When operating the compressor in moist (humid) or dusty atmospheres
 seektheadviceofyourcompressorsupplierwithregardtothettingofadryerandlter.
AIR PRESSURE:
 Thehoistisdesignedtooperatebestinthepressurerangeof5to6bar(72to90p.s.i).Thespeedsquotedonthemanufacturer’sliterature 
 areobtainableonlyat6bar(90p.s.i)inletpressure.Thehoistwilloperateatmuchreducedspeedatpressuresbelowthisgure.
AIR FLOW:
 Refertothehoistdatasheet,toselectthehosediameterwhichensuresadequateairow.Failuretoprovideadequateairowwillresultina 
 pressuredropinthesupplylineandcausethehoisttostallandthebraketoapplyuntilthepressureincreases.Inaddition,thebrakewillnot 
 releasecleanlyandwilloverheat.(Althoughnotinitselfahazard[thebrakefailssafe]itmayprovefrustratingtotheoperatorandahazard 
 mayariseasaconsequence.)
HOSE SUPPORT BRACKET:
 Whereahosesupportbracketandmanifoldhavebeenttedtothehoisttotaketheweightofanairsupplyhose,severalchecksmustbedone.
 ▪ Checkthehosehangsfreelyanddoesnotinterferewiththehoistchain.
 ▪ Checkthehoseisclearoftheloadtobelifted.
 ▪ Checkthependanthoseisnotobstructedbytheairsupplyhose.
 ▪ Checktheairhoseissupportedbythehoseclamp/former/festoonsystem.
 ▪ DOuseexclusivelycorrectlyratedandcertiedpneumatichosesandttingsintheairsupplyline.
 ▪ DOsupporttheairlineuptothehoist,asthettingandlter/lubricatorarenotdesignedtotakealoadandmaynotsupportthe 
weight of the hose.
 ▪ DOmaintaintheinternaldiameter(asperthetablethroughoutthesupplylength)orreducefromthelargerdiametertothe 
smaller diameter in the direction of the hoist.
 ▪ DON’Tusehydraulicttings.Theseoftenhaveareducedoricesizeresultinginadownlinedropinairpressure.
 ▪ DON’Tincreasefromsmallertolargerdiameterorinsertalengthofsmallerdiameterhoseinthesupplylineasthiswillresultin 
 reducedowandpressure.
 ▪ DON’Tcreatelowpointsintheairsupplylinewherewatermaybetrapped(orifunavoidableinstalladraintap).
 ▪ DON’Trelyonpneumaticttingstosupportairlines;theyarenotdesignedforthispurpose.
 ▪ DON’Tshortenthependantbyformingalooporacoil.Thiswillpreventthestrainerwirefromsupportingthependantandwill 
 causethehosestobecomedetachedorkinked.

MOUNTING THE HOIST
 TheairhoistisdesignedasaLIFTINGMACHINEandassuchisdesignedexclusivelyfortheliftingloadsvertically.Nonverticalliftingwill 
result in premature wear of the chain and chain guide and may result in damage to the limit arms or a failure of the limit arms to operate.
 ▪ Sitethehoistimmediatelyabovetheloadwhichistobelifted.
 ▪ Ensurethatthepointfromwhichthehoistissuspendedhasbeendesignedandtestedtoatleastthesamesafeworkingloadas 
the hoist itself.
 ▪ Ensurethatthesuspensionpointorshackletssnuglyintothebowlofthehoisttophookandthatthesafetycatchclosesto
prevent escape.
 ▪ UseonlycertiedliftinggearwithaSWLinexcessoftheloadtobeliftedtoconnecttotheloaditself.

secure position with the cords or pendant at waist height.
CLOSE HEADROOM WORKING
The lower hook of the TMH hoist includes a swivel arrangement. This allows the load to turn without twisting the chain. However, when
 repeatedlyhandlingloadswiththebottomhookclosetothehoist,especiallywhenrotationoftheloadisprevented,thereistendencyforthe 
 chaintoattempttoentertheguideatanangle.Thisisparticularlypronouncedontwofallunits.Ifthisproblemisnoticedwhendoingatriallift,
 ahighqualityballbearingswivelshouldbemountedbelowthebottomhookofthehoist.
CHAIN COLLECTORS
 Ifthehoisthasbeensuppliedwithachainbucket,andthechainhasbeenstoredwithinitduringshipment,removeallthechainfromthecollector
 byhand,andremoveanyknotsortwists.

4.5 FITTING OR REPLACING LOAD CHAIN
 Thehoistwillrequiretobehungupwithanairlineconnected.
 Thechainmustbefedoverthepocketwheelfromtheslackendanchorsidewiththeweldofeverysecondlinkfacingawayfromthewheel 
 axisi.e.weldoutwards.
 Caremustbetakennottotwistthechainduringinstallation.Thisisbestachievedbyholdingtheliveendofthechainasitemergesfromthe 
 hoist,ifthehoistisreevedontwopartsofchain,feedthroughthebottomblockwheelandagainasitemerges,thereafterfeedingituptothe
 anchorpin.Ifthechaincannotbettedtotheanchorwithoutrotatingitthrough90degrees,theendlinkshouldberemoved.
 Runthechainthroughthehoist,leavingashorttailatthe‘slack’end.Anchortheslackendwithouttwistingthechain.
 Onsinglefallhoiststheliveendissecuredinthebottomhookholder4xM12capheadboltsandnuts.
Feed the chain over the load wheel.
 Itisveryeasytotrapordamagethechainifextremecareisnotexercised.Alwaysexaminetherstlinkofchainafterpassingitovertheload
wheel. If damaged, remove the damaged link(s).
REPLACING EXISTING CHAIN
Cut away the centre portion of a link of the old chain to allow a chain diameter to pass through. Connect the spare link to the last link of the old
 chainandtherstlinkofthereplacementchain.Usetheoldchaintodrawthereplacementchainthoughthehoist.(Retainthesparelinktobe
re-used).
FITTING CHAIN TO AN UNCHAINED HOIST
 Ahandytoolcomprisesalengthofeithersoftinsulatedwire(about2mmdiameter)orapieceofexiblenylontubeofthesamediameter 
 approximately500mmlong.Totheendofthisattachasimilarlengthofstrongtwine.
 Thesoftwireortubeisfedoverthewheel,itsexibilityallowsittofollowthechainguideandre-emergeattheoppositeside.Thetwine
is attached to the end of the chain and drawn through, pulling the chain against the wheel. By applying power VERY SLOWLY in the
 samedirectionofwinding,theloadchainisdraggedintotherstpocketandovertheloadwheel.Ifanyresistanceisfeltasthechainattempts
 toenterthepocketitisimperativethatthechainisreleasedfromthepocketbeforetryingagain.Otherwisethechainwillbecometrapped 
and damaged.
