great care when using for the first few times as engagement may be sudden until the belt is sufficiently run in. 6.3.6 A DJUSTMENT OF THE SPRING OF THE PAWL FOR HOOKING THE GRASS-CATCHER If the grass-catcher tends to jump about and to open up when going over rough ground, or if it has difficulty in hooking back on after being emptied, the tension of the spring will need to be adjust- ed(1). Change the hooking point by using one of the holes (2) until the required result is achieved. 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 screwdriver. 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 prevent an uneven cut. Before re-fitting a wheel, smear some waterproof grease on the axle and carefully re-fit the snap ring (1) and washer (2). IMPORTANT NOTE EN 50MAINTENANCE 2 1 1 2
6.4.2 REPLACING 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. 6.4.3 R EPLACING BULBS The bulbs (18W) have a bayonet fitting and are installed in the bulb holder which can be taken out by turning it anti-clock- wise, using pliers. 6.4.4 R EPLACING A FUSE The machine is fitted with fuses (1) with differ- ent capacities and func- tions. Specifically: – 10 A fuse = protects the main and power circuits of the electron- ic board. When it blows, the machine stops and the dash- board switches off. – 25 A fuse = protects the battery charger cir- cuit. When it blows, the battery light comes EN 51 MAINTENANCE 1
on to indicate that the battery is going to run out and the machine will have problems starting. In electric tipping models: – 10A fuse = protects the control motor circuit. If it trips, the tipping system stops working electrically, so you can empty the grass-catcher using the manual lever (if fitted). 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 52MAINTENANCE

EN 56ACCESSORIES ON REQUEST 8. ACCESSORIES ON REQUEST 1. FRONT COUNTERWEIGHTS These improve stability at the front of the machine, particularly when being used on ground which is mostly sloping. 2. STONE-GUARD KIT For use in place of the grass-catcher when the cut- tings are not to be collected. 3. TOWING HITCH For towing a small trailer. 4. CLOTH COVER Protects the machine from dust when not in use. 5. CB01 MAINTENANCE BATTERY-CHARGER This makes it possible to keep the battery in good working order when the machine is in storage, guar- anteeing an optimum level of charge and a longer life to the battery. 6. KIT FOR “MULCHING” (only on prearranged models) It finely chops the grass cuttings and leaves them on the lawn, instead of collecting them in the grass-catch- er. 7. DEFLECTOR CHUTE KIT (only for mod. 102) Improves grass collecting when the cutting deck is close to the ground. 1 3 4 5 6 7 2
