EN 40MAINTENANCE 6.3.3 ADJUSTMENT TO THE ENGAGEMENT AND BRAKE OF THE BLADES When the blade disengagement lever is operated, it also brings the blade brake into operation which stops the blades within few seconds. A stretched cable and changes in the length of the belt can impair the blades’ engagement or rotation. To compensate this, turn the adjuster (1) until the correct spring length (2) is achieved (measured from the outer ends of the springs with the blades engaged). 6.3.4 B RAKE ADJUSTMENT Should the brakes work poorly, consult a Licensed Service Centre immediately. 6.3.5 A DJUSTING THE TENSION OF THE DRIVE BELT Should you notice a drop in forward drive power, adjust the tension of the spring of the stretcher to return to former condi- tions. The adjustment is made by opening the engine hood to reach the right side of the engine. Turn the nuts (2) as much as necessary to reach length “A” of the spring (1) of: A= 119 - 121 mm (For mechanical drive models) A= 120 - 122 mm (For hydrostatic drive models) measured to the outside of the end of the spring. When the adjustment has been made, tighten the nuts (2). ➤ ➤ 294 ÷ 96 mm1 1 A 2
EN 41 MAINTENANCE When replacing the belt, take great care when using for the first few times as engagement may be sudden until the belt is sufficiently run in. 6.4 DISMANTLING AND REPLACEMENT 6.4.1 R EPLACING WHEELS Stop the machine on a flat surface and put a block under a load-bearing part of the frame on the side that the wheel is to be changed. The wheels are held by a snap ring (1) which can be eased off with a screwdriv- er. The rear wheels are directly coupled to the differential axle shaft and fastened by a key that forms part of the wheels hub. Should you substitute one or both rear wheels, ensure that they are of the same diameter, and check that cutting deck is horizontal to pre- vent an uneven cut. Before refitting a wheel, smear some waterproof grease on the axle and carefully refit the snap ring (1) and washer (2). 6.4.2 R EPLACING AND REPAIRING TYRES The tyres are of the «Tubeless» type and therefore all puncture repairs will have to be carried out by a tyre-repair expert in accordance with the methods for this kind of tyre. IMPORTANT NOTE NOTE 2 1
6.4.3 REPLACING BULBS( if fitted) The bulbs (18W) have a bayonet fitting and are installed in the bulb holder which can be taken out by turning it anti-clockwise, using pliers. 6.4.4 R EPLACING A FUSE The machine is fitted with fuses (1) with different capacities and functions. Specifically: – 6.3 A (delayed) fuse (1) = protects the main and power circuits of the electronic board. When it blows, the machine stops and the dashboard light switches off. – 25 A fuse (2) = protects the battery charger cir- cuit. When it blows, the battery gradually runs out and the machine will have problems start- ing. The fuse capacity is indicated on the fuse. A blown fuse must always be replaced by one of the same type and ampere rating, and never with one of another rating. If you cannot find out why the fuse has blown, consult a Licensed Service Cen- tre. 6.4.5 R EPLACING BELTS Replacing belts is quite a complicated process of dismantling and subsequent adjustment and must only be carried out by a Licensed Service Centre. Replace the belts as soon as they show obvious signs of wear! ALWAYS USE GENUINE REPLACEMENT BELTS! NOTE IMPORTANT ➤ EN 42MAINTENANCE 2 1

The engine stops but the light stays on 10.The blades do not engage 11.Uneven cutting and ejection– forward speed too high in relation to cutting height (☛5.4.5) – the safety devices cut in The protection of the electronic card has cut in due to: – earthed micro-switch – battery contains electrolyte but is not charged – overvoltage caused by the charge reg- ulator – badly connected battery (poor contact) – engine badly earthed – problems in the engine – cable lengthened or belt loosened – cutting deck not parallel to the ground – blade cutting badly – forward speed too high compared to height of grass (☛5.4.5) – cutting deck full of grass– reduce the forward speed and/or raise the cutting deck – check that the conditions allowing starting are met (☛5.2.b) Put the key in position «STOP» and look for the cause of the problem: – check connections – recharge battery (☛6.2.5) – contact a Licensed Service Centre – check connections (☛3.4) – check engine earth connection – contact a Licensed Service Centre – turn the adjuster (☛6.3.3) – check the tyre pressures (☛5.3.2) – realign the cutting deck to the ground (☛6.3.2) – check that the blades are fitted prop- erly (☛6.3.1) – sharpen or fit new blades (☛6.3.1) – check the tension of the belt and con- trol cable of the blade engagement lever (☛6.3.3) – reduce forward speed and/or raise the cutting deck – wait for the grass to dry – clean the cutting deck (☛5.4.8)
EN 45 TROUBLESHOOTING PROBLEM LIKELY CAUSE SOLUTION 12.Unusual vibrations while working 13.With the engine running, the machine does not move when the drive pedal is pressed ( for hydrostatic drive mod- els) ➤ – the blades are imbalanced – blades loose – fixing bolts loose – disengage lever in position «B» (☛4.33)– balance or replace any damaged blades (☛6.3.1) – check that the blades are firmly fitted (☛6.3.1) – check and tighten all the fixing bolts of the engine and frame – put into position «A» If problems continue after having carried out these operations, contact a Licensed Service Centre. Do not take on complicated repair work if you dont have the necessary equipment and the technical knowledge. The guar- antee is automatically revoked and the manufacturer declines all responsibility for any repairs which are badly done. !WARNING!
