13 MACHINE LOADING/UNLOADING INSTRUCTIONS Unload the machine using a lifting device fitted with a hook (hoist, crane etc.) whose minimum capacity is 1500 kg. Machine weight with standard equipment : BNG 230 = 715 kg / 1573 lbs BNG 270 = 960 kg / 2112 lbs BNG 310 = 1155 kg / 2541 lbs Lifting device should be attached to the lower anchorage holes (Ø 40 mm) on the machine s side plates and to the top link pin. When the machine is being manoeuvred the wheels should be blocked in the transport position. Cables and hooks, in good condition and suitable for the machine s weight should be used. Check the load is distributed evenly before manoeuvring

14 FITTING INSTRUCTIONS AND WORKING HEIGHT ADJUSTMENT 1) Fitting instructions for the wheels or the roller To reduce transport size, machine can be delivered with the gauge wheels or the roller not fitted. Gauge wheel version : - Fix the yokes (P) in place on the inside of the rear beam (L) - Fix the wheel arm supports (R) on the yokes (P) using self locking nuts. - When using the machine with an open hood and security elements, ensure that the wheels do not clash with the side plates when pivoting. When transporting, the 2 wheels should be pivoted towards the inside and be locked in place using the pins designed for this. Gauge roller version : - Fix the gauge roller using the fixation holes (F) designed for this on the side plates. 2) Adjusting the wheel track The wheel supports can be slid onto the rear beam making sure that the machine s wheels are not positioned in line with those of the tractor (creation of ruts by the tractor wheels in damp conditions changes the regularity of the working height). When shredding maize stems, shredder wheels can be placed to run on top of the rows in order to keep a constant working height

15 3) Adjusting the working height The knives must not touch the ground. The minimum working height must not be lower than 40 mm. Gauge roller version : - raise the machine above the ground, - fix the parking stand in place, - loosen the screws (A) and position the roller supports at the required height, - tighten the screws. Gauge wheel version : - raise the machine above the ground, - fix the parking stand in place - place the wheel arms at the required height using the fixation holes on the wheel arm (C). BNG 230 BNG Never reverse when the wheels are resting on the ground. Tyre specifications Model Type of tyre Tyre inflation pressure BNG / Ply 3.0 bars / 40 psi BNG / Ply 3.5 bars / 50 psi BNG / Ply 3.5 bars / 50 psi

16 UNCOUPLING THE MACHINE Only uncouple the machine on a level firm surface. Stop the tractor motor. Take out the ignition key. Wait until the moving parts have come to a complete stop. - Lower the hydraulic lift so that the machine is resting on the ground. - Uncouple the top link on the machine side. - Rest the PTO transmission shaft in the support (G) to avoid it touching the ground and being dirtied. - Fix the stand (P) in place using pin (F) and spring cotter pin (S) - Disconnect the lower link arms and move the tractor away. - When setting down on the outside, check that the front part of the machine is slightly tilting downwards so that the water can drain away

17 COUPLING TO THE TRACTOR In the area around the 3-point hitch an operator or bystander can easily be pinched or trapped. Ensure that there is nobody in this area when operating the lifting mechanism. - Fix the pins (D) in place as well as the lynch pins (S) - Raise the parking stand (P) and lock it using pin (F) and spring cotter pin (S) - Fold hook (G) towards the rear and connect up the PTO shaft. Prevent the PTO shaft guard from rotating using chains (C). During transport, lock the tractor lift arms in order to avoid any side movement. IMPORTANT : Machine is correctly attached when horizontal in the working position. To do this, adjust the top link length

18 MACHINE OFFSET (BNG 230 only) The BNG 230 shredder can be offset by 40 cm to the right in relation to the tractor central axis. This offset is particularly useful for shredding maize so that the tractor does not press down the stalks. When offsetting the hitch frame, ensure that the mounting bolts and nuts are correctly torqued. (A) = spacer to be fixed as shown in the diagram below according to the attachment position

19 PTO TRANSMISSION SHAFT Connect the PTO shaft between the drive shaft of the machine and the tractor PTO. Ensure that the length of the PTO shaft is correct: 1 When extended to maximum ensure at least 300 mm / 12" tube overlap. 2 When in its shortest position, the tubes must not contact the opposite fitting. At least 2 cm / 1" must remain between the end of the tube and the opposite fitting. If required, cut the guards and tubes by the same length (photos 1 & 2), chamfer and clean the tubes (photo 3), and grease the inside of the outer tube (photo 4). 3 Never work the PTO shaft at too sharp an angle (30 maximum). We advise strongly that these preliminary adjustments be carried out, to avoid damage to the transmission. To avoid risk of serious accident, check carefully that the transmission guards are always correctly in place, and prevented from rotating by the chains. On the machine side, the chain should be fixed to the guard cone on the central gearbox. Replace immediately any damaged guard

20 ROTOR SPEED On BNG 270 and BNG 310, the correct rotor rotating speed can be obtained at 540 or 1000 PTO rpm. When the tractor has a PTO speed of 1000 rpm, it is advised to use it in order to obtain the maximum power generation. Using the machine at 540 or 1000 rpm is determined according to the position of the pulleys. Stop the tractor motor. Take out the ignition key. Wait until all moving parts have come to a complete stop. Position of pulleys (P.T.O. 540 rpm) Position of pulleys after having switched round (P.T.O rpm) Locking bolt torque on pulley : 2.5 danm / 20 ft.lbs. After reassembling the pulleys, check the parallelism between the rotor axis and the transmission axis (see chapter tensioning the belts page 25). Never work in stony or rocky grounds

(open position, figure B). For the positioning of the retractable hammers, refer to the opposite diagram

23 Always mount the retractable hammers in pairs on diametrically opposed holders to prevent rotor vibrations. Stop the tractor engine, remove the starter key and wait for all movements to stop prior to adjusting or maintaining the machine. The retracted position is obtained by blocking the connecting rods (1) against the rotor tube by means of spacers (2) and self-locking screws (3) (figure A). The opened position is obtained by removing the spacers (2) and self-locking screws (3) (figure B). To shred crops on ridges, the adjustment of the working height is made as follows : - place the tractor with the shredder in raised position between the rows. - lower the shredder so that the hammers are at ridge level. - adjust the gauge wheel height.

24 LIGHTING AND SIGNALLING ELEMENTS NOTE : The photos shown in this manual show the BNG 270 fitted with «lighting elements and signalling panels». According to the legislation in force in the different countries, this equipment is delivered with the machine or is available as an optional accessory under code : - No for BNG No for BNG No for BNG 310. To fit the kit, proceed as follows : - fix the 2 panel supports (A) on the 2 side plates (P) (photo 1) using 4 hexagon screws (H) (M 12 x 18) (torque 10 danm) (photo 2), - mount the 4 signalling boards (D) on the 2 supports (A) using bolts (M 10 x 20) and M 10 nuts (torque 6 danm) (photos 1 and 2), making sure that the red and white stripes are pointing in the right direction (the red corner must always be pointing upwards and outwards towards the panel), - fix the front lights (K) on the front signalling panels (see photo 1) - fix the rear left light (R ), whose connection plug is marked «L» and is marked in white, on the rear left signalling panel (photo 2) - fix the rear right light (I), whose connection plug is marked «R», on the rear right signalling panel (photo 2) - Affix the white adhesive reflectors (Q) on the front beam (photo 1) and the red adhesive reflectors (N) on the rear beam (photo 2) - Proceed with the installation of the wiring harness connector. This is fixed to the plates of the machine using rylsan clamp collars and self-adhesive bases. Notes : - The «road signalling» device requires the presence of an 7 pin electric plug at the rear of the tractor. - When parking the machine, ensure that the electric plug (E) is placed in the hole designed for this on the hitch frame

25 MAINTENANCE 1 Greasing - lubrication - Check that breather plug (T) is fitted correctly. A malfunction may cause too much pressure to build up in the gearbox and risk damaging the oil seals. - Primary PTO transmission shaft : after every 8 hours of use, clean and grease the joints of the PTO as well as the shaft tubes. - Transmission casing : first oil change after 10 hours of use, then every 250 hours or once per season. Type of oil : BNG (until serial number ) - BNG 310 : SAE 140 EP. BNG 270 (as from serial number ) : SAE 90 EP. Quantities : BNG 230 : 2,1 l. BNG 270 until serial number : 2,9 l as from serial number : 2,3 l. BNG 310 : 3,1 l. Check the level of oil regularly using the plug situated halfway up the side of the gearbox. Filling is done through the opening on the breather plug. The plug for the oil change is situated under the gearbox. - Rotor bearings (R) : grease every 8 hours - Wheel pivoting axle and roller bearings : grease every 50 hours Clean and oil the protection plate pivoting axles (B) regularly. Check that they are not warped and pivot freely

26 2 Belt Tension Check belt tension regularly especially during the first hours of use. The belt tension can be measured using a ruler scale (R ) placed through the hole in the hood. Checking the belt tension - Stop the tractor engine, remove ignition key and wait for all moving parts to stop before leaving the tractor - Loosen screws (A) and (B) which fix the central casing to the frame of the machine. - Loosen adjustment screw lock-nuts (C) and (D) - Turn the screw (F) clockwise until the belts are correctly tightened. The belt is correctly tightened when a force of 20 kilo gives a belt deflection of 10 mm/0.4" (see transfer) - Adjust adjustment screw (G) by the same amount so that the central transmission shaft (PR) is parallel to the machine rotor - Retighten screws (A) and (B) as well as lock-nuts (C) and (D)

27 Checking the parallelism between the rotor axis and transmission shaft Before adjusting, maintaining or repairing the machine, turn off the engine, remove ignition key and wait until all moving parts have come to a complete stop. - Remove the belt guard - Place a ruler against the sides of the rotor pulley - Slide the rotor pulley so that the ruler comes against the sides of the other pulley - The ruler must be in contact with the 2 sides of the two pulleys. If not, screws (F) and (G) should be adjusted again as well as the lock-nuts (C) and (D) - Remount the belt guard

28 KNIFE FITTING Check the condition and fixing of the knives regularly. Replace any worn or damaged parts immediately with genuine KUHN parts. BEFORE CARRYING OUT THIS WORK, ALWAYS DISCONNECT THE PTO SHAFT. ONLY USE GENUINE PARTS! - Remove all worn knives - Weigh all the new knives individually and put all the knives which have the same weight together. - Fit all pairs of knives with the same weight on diametrically opposite mountings. - Place the heaviest pairs to the outside of the rotor and lightest pairs towards the centre. - When changing a knife, tighten the M20 nuts to a torque of 20 danm/150 ft.lbs. After tightening the nut, there should still be a sideways play of 1 to 2 mm. - After fitting the knives, couple the machine to the tractor. Raise it slightly and gradually increase the PTO speed until it is at 540 or 1000 rpm (see table on page 10). - When the knives are correctly fitted, there should be no vibrations while the rotor is turning. - Check that the ventilation pallets are correctly fitted!
