8 SAFETY PRECAUTIONS DO NOT ttempt ny mintenne of or justment to the mhine while it is running. Before rrying out ny work on the mhine follow the three sfety instrutions elow: LOWER THE CUTTING UNIT ON TO THE GROUND PUT THE PTO OUT OF GEAR STOP THE TRACTOR ENGINE At ll times ensure tht the PTO shft gur is in position, seurely fitte n in goo onition n tht the trtor PTO shft shiel is fitte. 2 Reple the PTO shft gur if ny of the following re evient: gur rke or mge ny prt of the PTO shft expose. Ensure the PTO shft gur is free to rotte n the nti-rottion hins re seurely fitte n effetive. 3 Ensure tht the orret gurs for the prtiulr opertion re properly fitte to the mhine n trtor t ll times n tht they re in goo onition. See setion on Gurs n Rottion. 4 The term REVERSE rottion in the following notes inites the iretion of the rottion of the rotor shft in reltion to the trtor wheels, ssuming tht the trtor is moving in forwr iretion. 5 EMERGENCY STOP. To stop the rotors in n emergeny use the trtor stop ontrol. Use of the trtor stop ontrol must only e one in n emergeny. Its use to stop the rotor n use mge to the hyruli omponents. After n emergeny stop of the rotor; ensure tht the PTO lever n rotor ontrol is set to OFF efore restrting the trtor. 6 While the trtor is running ll personnel shoul keep well ler of the re roun the mhine s there re numerous rushing, shering, impt ngers use y the mhine opertion. 7 THINK SAFETY - WORK SAFELY e f AVOID WIRE. It n e extremely ngerous if wire thes in the rotor, n every re must e tken to ensure this will not hppen. Inspet the working re efore ommening. Remove ll loose wire n ostrutions n lerly mrk those tht re fixe so tht you n voi them. Any unusul noise from the utting unit re inites tht the rotor shft my hve een foule y n ostrution. A visul inition tht wire is in ontt with the flils my e suen movement of the vegettion he of the utting unit. In ny suh event STOP the trtor engine INSTANTLY. On no ount move the utting unit until the rotor hs ompletely stoppe. NEVER IN ANY CIRCUMSTANCES run the rotor to 'ler itself'. When the rotor hs stoppe inspet it n remove ny ostrution tht my e present. If working uner rise mhine ensure tht it is sfely supporte. Before working on the rotor lwys stop the trtor engine. CHECK the flils for wer n the tthment olts for tightness every y uring work (see Mintenne). A few moments whenever the mhine is stoppe, e.g. whenever removing ostrutions, will help reue flil wer or loss. Keep your forwr spee to level pproprite to the operting onitions. High-spee mnoeuvres with the rms strethe out re very ngerous, prtiulrly on uneven groun. DIRECT the ut mteril wy from the trtor. It is importnt tht while operting the ut mteril is not irete towrs the opertor. Avoi positioning the utting unit so tht the unersie is ngle towrs the. 4 1

9 SAFETY PRECAUTIONS 1003 g h i Keep reful wth for pssers y who my invertently get in the wy of ut mteril eing thrown from the utting unit. Stop the rotor shft until ll people re well ler. Do not operte or trnsport with the rms extene rerwrs s instility will result. Keep the roller in position t ll times. 7 GRASS AND HEDGE CUTTING The stnr uil for hege trimming is REVERSE rottion with the steel gur n wire trp t the front of the utting unit. e The stnr uil for grss utting is REVERSE rottion with the flexile flp gur fitte t the front of the utting unit. See Setion 12 for etile guring instrutions. A wire mesh gur must e fitte on the outsie of the winow, etween the river n the utting unit, in suh position s to give the river mximum protetion. Where hege trimmer is use in onjuntion with trtors not fitte with glze sfety, ler sfety sreen must e fitte to the trtor etween the opertor n the utting unit. The sfety sreen must e use on s where winows re likely to e left open for ventiltion purposes. We emphsise tht winows on the operting sie MUST e intt, len n lose, or ler sfety sreen must e fitte where hege utting n trimming opertions re rrie out. The wire mesh gur in () ove must lso e fitte 8 SAFETY DECALS Sfety els re lote on vrious points of the mhine. They n e ientifie y the yellow upper pnel epiting the hzr, n the lower white pnel initing mens of voine or preutions to e tken. These els hve no text. It is essentil tht ll opertors n personnel ssoite with the mhine fully unerstn their menings, whih re shown on the following pges.

27 GENERAL OPERATION OPERATOR These notes re proue for guine n re intene to help you otin the est results from your mhine, with the minimum of troule n owntime. Re the following pges refully n fmilirise yourself with their ontents. Mke note of the seril numers; stmpe on the top of the minfrme n the utting unit itself, insie the front over of this mnul. Alwys quote these numers in ny orresponene with your eler. 2 INITIAL CHECKS Chek tht the trtor is equippe to eliver 540 rev/min t the PTO shft. The mhine is esigne to run t this spee n IN NO CIRCUMSTANCES MUST THE PTO EXCEED 600 REV/MIN. 3 MACHINE PRE-START CHECK Chek tht the rotor is free from ostrutions espeilly piees of wire. Chek tht ll flils re in goo onition n seurely tthe to the rotor. Chek tht ll gurs re in their orret ple (see Setion 12) n lso tht they re in goo onition. Chek the oil level in the tnk. The level is orret when up to the initor mrk in the sight glss or visile in the ottom of the filler ssemly striner. DO NOT OVERFILL. Most oils inrese in volume s they wrm up n erte n n then spill out through the rether. (Refer to Approve Oils Setion.) 4 STARTING UP PROCEDURE COLD START UP When strting the mhine for the first time, prior to ommening work, it is essentil not to run the pump initilly t too high spee. Therefore the trtor PTO spee shoul not exee 360 rev/min, n shoul only reh this spee grully. The ol strt up instrutions given elow shoul e stritly here to. Ensure tht the trtor PTO rive is in neutrl. Ensure tht the rotor ontrol lever (fitte to twin pump inepenent mhines) operting the iverter vlve (jent to the rm opertion levers) is in the rotor-stoppe position. Strt trtor engine, run t ile spee n engge PTO rive. Slowly move the rotor ontrol lever to strt the rotor. e Grully inrese engine spee. f Continue inresing engine spee until rotor is running smoothly n PTO spee is pproximtely 350 rev/min. g Run rotor t this spee for minimum of 5 minutes to llow oil in the system to wrm up. h The mhine is now rey for work. NORMAL START UP i j Never ttempt to strt the rotor while it is uner lo. Alwys free the rotor from ny ostrutions first. Never inrese or erese PTO spee rpily s this n le to pump n motor mge. 13 1

28 GENERAL OPERATION TRANSPORT Normlly the mhine will nee to e riven to the work site efore ommening work. To keep the mhine/trtor with to minimum it is neessry to fol the rms to the trnsport position. On moels with the slew/rekout rm the rms my e slewe k to provie nrrow trnsport position. Keep hoses wy from tyres. When the mhine is in the trnsport position it is essentil tht ll the isoltor vlves re lose. When trnsporting with the rms slewe k, keep the first rm vertil s the rms n oune forwr n mge the trtor. When trnsporting on the highwy, oey ll relevnt highwy lws. 13 2

29 GENERAL OPERATION CUTTING CONTROL Do not swing utting unit inor eyon vertil ut when rms re rise ove trtor height. In this position loss of ontrol n our. Roller Height The roller on the utting unit is set in its mile position efore the mhine leves the ftory. It shoul e reset to suit the operting onitions n ut length require. Grss Cutting Ajust the height of the roller to give require ut length. The higher the roller is rise the shorter the grss. Note: The higher the roller is set the greter the flil wer. Hege Trimming Rise roller to its mximum to give lowest ut possile. IMPORTANT THE ROLLER MUST BE KEPT IN POSITION AT ALL TIMES AS IT IS AN ESSENTIAL PART OF THE CUTTING UNIT GUARDING. 7 STOPPING THE CUTTING UNIT The rotor must only e engge/isengge y mens of the rotor on/off ontrol lever or swith epening on metho of ontrol (le or eletri). see Setion 7. Stopping the rotor y use of the trtor engine stop or PTO ontrol risks mge to the utting unit's hyruli system, n shoul only e use in n emergeny. If the rotor is stoppe y use of either the trtor engine stop or PTO ontrol, re must e tken to ensure the rotor ontrol lever is returne to the OFF position efore restrting the trtor. 8 ARM FLOAT ACCUMUATOR (Optionl) The mhine my fitte with n umultor to llow the rms to flot for grss utting pplition. The purpose of the rmflot is to permit the utting unit to follow uneven groun without opertor intervention s fr s possile n to llow most of the weight of the utting unit to e rrie y the trtor, thus minimising the teneny to slew. This lso reues wer on the rotor n in the erings of the roller. The rmflot is not use when hege trimming, s the utting unit woul e very iffiult to ontrol n uneven (stellte) results woul e otine. To shut off the rm flot lose the isoltor vlve. When opening the isoltor vlve ensure ll he weight is on the groun, otherwise the first rm my move unexpetely. WARNING THIS VALVE MUST BE CLOSED WHEN THE MACHINE IS TRAVELLING, WHETHER IN TRANSPORT POSITION OR NOT. 13 3

30 GENERAL OPERATION ADJUSTABLE FIRST RAM POSITION The purpose of the first rm position justment is to mximise the working envelope of the mhine. Two positions re ville - A, n B. The lower position "A" mximises the ownnk reh of the mhine. The upper position "B" optimises the mhine's geometry for high utting n nrrow lne situtions. IMPORTANT WHEN CHANGING THE FIRST RAM MOUNTING POSITION, DO NOT DISCONNECT ANY HYDRAULIC FITTINGS. ENSURE THE FULL HEAD WEIGHT IS ON THE GROUND AND THE TRACTOR IS SWITCHED OFF. 13-4

31 OPERATING HINTS OPERATING HINTS Keep trtor PTO spee t rev/min to mintin the orret rotor spee for the jo to e tkle. Depening on the uil of the utting unit fitte this my e either 3000 rev/min vise for HEDGE CUTTING, or 2485 rev/min vise for GRASS CUTTING (see Setion 16-10). Slower spees MAY reue the qulity of ut otine y the rotor, ut stisftory performne n e mintine own to rotor spee of 2100 rev/min. This n e n vntge with trtors with high ottom ger. e Exmine the piee of work to e ut. It is very importnt tht the work site is inspete efore utting n ll hien ostrutions remove or their position lerly mrke so tht they my e voie. Chek heges for wire n fening stkes, n ithes for tree stumps, rin pipes, lrge stones, et. Stlling in hevy growth is likely to use mge to the rotor. Do not operte the mhine with the utting he slewe more thn 40 kwrs. IMPORTANT DO NOT ALLOW PERSONNEL NEAR THE MACHINE WHILE IT IS OPERATING. f g h i DO NOT ngle the utting unit in suh wy s to throw ut mteril towrs the trtor. Avoi rushing into the work. Rememer tht the unit hs to hop up mteril s well s ut it to the require height. When hege utting lose the isoltor vlve on the rm flot umultor, (if fitte.) Alwys give the rotor shft enough mteril to 'ite' into, prtiulrly when hege hs lot of lef n very flexile thin stems. 2 GRASS CUTTING (Rotor Shft Spee 2485rpm.) Run the rotor t norml spee, i.e. 540 rev/min. PTO spee e f g h Avoi tking in too muh grss y regulting trtor forwr spee. If rotor shft slows own or egins to hoke up in grss, rise the utting unit little n llow grss to fll ler. Before proeeing with the utting let the rotor spee reover gin. Avntge my e gine in exeptionl onitions y tking nrrow ut with prt of the utting unit ler of the work. When working longsie or lering ithes, tke first ut long the ege of the ith so tht the ith limits n e seen. When working over hege or into ith, keep the highest point of the mower rms iretly over the ostle. Do not run the mhine for prolonge perios when the he is not t 90 to the iretion of trvel. 14-1

32 OPERATING HINTS HEDGE TRIMMING (Rotor Shft Spee 3000 rpm). Consier how the jo shoul e one efore ommening work, s every hege hs ifferent height, with, thikness n ensity of growth. Heges tht hve previously een ut y mhine ten to hve enser growth, n lthough they n e ut to ny esire shpe, it is visle to trim to the sme shpe n height s efore. The flils use the new growth to 'tiller' (spre out) n thiken up the hege. Therefore it is visle to ut the hege sie t slight ngle rther thn stright, otherwise the hege my eventully ie t the ottom ue to lk of light. The following informtion gives few hints on how to tkle hege. First trim the top own to the height of the previous yer's trim in one ut, ut o not ut into it s the ol growth will e very thik n strong n n use premture wer to the flil utting eges. Next trim the sies to the previous trim ut not into it. IMPORTANT DO NOT ANGLE THE CUTTING UNIT SO THAT ANY DEBRIS IS THROWN THROUGH THE HEDGE WHEN TRIMMING THE FAR SIDE OF THE HEDGE. ALWAYS ENSURE CUT MATERIAL IS DIRECTED AWAY FROM YOU OR ON TO THE GROUND. Finlly, lower the roller n trim long the ottom of the hege to ler eris n unergrowth. 4 STALLING THE ROTOR If the rotor oes eome hoke the trtor will stll, the elts will slip or the relief vlve will operte. If this ours follow the instrutions elow: Stop forwrs motion n isengge rive to utting unit immeitely y pling the lever ontrolling the rotor in the stop position. Ensure tht the rotor hs stoppe n lift the utting unit. Stop trtor engine. Remove ny ostrution tht my e present on the rotor. If working uner the rise mhine ensure tht it is sfely supporte. NEVER IN ANY CIRCUMSTANCES run or reverse the rotor to "ler itself". 14 2
