Keep hold of the starter handle and let the rope run back slowly. To stop: Put the accelerator lever into STOP position. n SAFETY FEATURE All motor-cultivators are provided with a safety feature which acts. The device causes the transmission to disconnect automatically anytime the respective control lever is released. n TRANSPORT A forklift truck should be used to move the machine. The forks should be opened as far as possible and inserted into the pallet. The weight of the machine is given on the Manufacturer’s data plate together with the other technical information. n HOW TO ASSEMBLE YOUR MOTOR-CULTIVATOR Unless otherwise agreed, the motor-cultivator is delivered disassembled and placed in a packing case. For assembly to be completed, the step by step procedure is as follows. n INSTALLING THE HANDLEBARS (Fig. 2) Fix the handlebars (Fig. 2, detail 1) to its mount (2) using screws (3). Important! The larger ENGLISH 9diameter washers must be installed by the slots. Adjust handlebar height with its xing screws (3). Position the gear lever (4) putting though its guide (5) and push the tip into the hole on the swivel (6) and clamp it with safety pin (7). n HOW TO MOUNT THE ACCELERATOR WIRE (provided with metal sheath) Fig. 3 Position the lever (g. 3, item 1) on the engine at the end of its stroke as shown by arrow “A “ in the gure. Move the throttle lever(2) on the handlebar to the end of its stroke as shown by arrow “B “ in the gure. Insert wire (3) into hole (4), secure the sheath (5) with retainer (6) and screw (7). The throttle wire must be xed to the engine at the sparkplug side. ATTENTION: in the position “stop” the throttle lever must stop engine. n BELT STRETCHER DRIVING WIRE (Fig. 4) The driving cable (1) is already linked to the belt stretcher lever of the frame to the lever (2). Please tighten the lever (2) on the handlebar using the screw (3) you can nd into the loose parts bag. n ATTACHMENTS ASSEMBLY (Fig. 5) The cultivator has a quick couple for attachments. Assemble the belt on the upper pulley A with the following attachments : grassland mower and rotavator. Assemble the belt on the lower pulley B with the following attachments : brush and cutting bar. n ATTACHING THE MOWER BAR (Fig. 6a) The cultivator has a quick couple for attachments. The motor should be shut down and the machine horizontal. Insert the cutter bar pin (1) halfway into its seating (2). Install the belt (3) in its pulley by moving the guide pin all the way to the end of its travel. Position 1 and 2 : turn the handle (13) until you are able to couple the spring (14) to the connection (15) . Position 2 and 3 : to complete the above coupling , rotate the handle (13) in the opposite direction until you are able to tension the spring (14). Replace the cowling (6) with its centering pin (7) and the threaded pin (8). Tighten home the nut with its washer on the cowling. n ATTACHING THE CULTIVATOR (Fig. 6b) The cultivator has a quick couple for attachments. The engine must be switched off and the machine on level ground. Insert the cultivator pin (1) halfway into its seating (2). Install the belt (3) in the appropriate pulley and push the pin (1) all the way in. Position 1 and 2 : turn the handle (13) until you are able to couple the spring (14) into the slot (15) . Position 2 and 3 : to complete the above coupling , rotate the handle (13) in the opposite direction until you are able to tension the spring (14). Install the cover (6) using its centering screw (7). The reverse gear blocking lever (8) will be correctly positioned with the gear lever (9). Tighten home the nut and its washer to x the cover (6) n REVERSING ROD ASSEMBLING (Fig. 12) Connect the extremity of the rod (2) in the hole of the lever (3), so lock with the R-shape pin. n ATTACHMENT DRIVE BELT REGISTRATION (Fig. 7) To increase belt tensioning between machine and attachment, use the register (2) so that the attachment begins to work only when the control lever has been moved more than halfway its travel (Fig. 7) If a mower is attached, to increase the tension on the two bottom mower drive belts, slacken off nut (9) and remove the washers between the half-pulleys (Fig. 5). If a cultivator is attached, check belt tension after two work hours (3, Fig. 6). n HOW TO OPERATE THE DRIVE OF THE CUTTING BLADE (Fig. 7): disconnect the safety lever (3), then push down the lever for the tool insert (4). ENGLISH 10n BELT-STRETCHER CONTROL ADJUSTMENT ( Fig. 8) Warning - Tyres should start rotating only when control lever is beyond halftravel. When lever is pulled to full extent (working position), the belt-stretcher load spring (2) should extend by 6 to 8 mm approx. For above described conditions be reached, action is to be taken on nut (1) set close to the belt stretcher control assembly. n REGULATING THE HANDLEBAR The handlebar can be height or side adjusted. Before beginning any work, it is good standard operating procedure to adjust the handlebar to the needs of the operator so that the machine can be easily manoeuvered at all times. The handlebar can be side adjusted so that the operator can use the machine without treading in the soft ground or damaging the crop. n HANDLEBAR SIDE ADJUSTMENT (Fig. 2) There are three positions for the handlebar side adjustment and these can be used either with rear-mounted attachments such as a cultivator or with front-mounted attachments such as a mower. Follow these steps: Turn lever (8) anticlockwise to disengage the clamp. Move the handlebar to the position you want it in. Clamp the handlebar again by turning lever (8) clockwise and check to be sure that the teeth are perfectly meshed. When turning the handlebar 180°, do so only clockwise so as not to damage the wires that run along the column. Furthermore, detach the gear change rod (4) and reconnect it when the handlebar is in its new position. When the handlebar is turned 180°, the position of the gears will be reversed - in other words, the reverse gear will become the forward gear and vice-versa. n HANDLEBAR HEIGHT ADJUSTMENT (Fig. 2) 1) Slacken off screws (3), adjust the handlebar to the required height 2) re-tighten the screws (3). n CUTTING BAR HEIGHT ADJUSTEMENT (Fig. 9) Adjust cut height with the adjusting shoes as needed but bearing in mind the type of terrain being cut. Follow these steps: a) Slacken off nut (1) - b) Move the shoes (2) to the required position - c) Retighten the nuts (1). Repeat on the other shoe. n REGULATING THE KNIFE (Fig. 10) After changing knife or after a certain number of work hours, the knife guide should be regulated by means of screws (1) and their locknut. To check the results after each regulation, rst remove the cowling and then turn pulley (2) slowly by hand and check to make sure that the knife is moving easily. n DEPTH ADJUSTMENT (Fig. 11) To ensure good soil cultivation and smooth machine movement, the attachment/ cultivator has a depth setting device (1) that regulates spade working depth. When the depth control lever (2) is pulled back and moved up or down, spade penetration into the soil is regulated. The cultivator is correctly regulated when the machine moves forward smoothly without lifting out of or digging into the soil. In the rst case (lifting out), move the lever to position “B” and in the latter case (digging in) move the lever to position “A”. CULTIVATING HARD GROUND: move the depth lever to position “B”. This position corresponds to a small soil penetration depth. CULTIVATING SOFT GROUND: move the depth to position “A”. This position corresponds to a deep soil penetration depth. Turn the engine on with the depth lever in position “B” as this enables the spades to break up the top surface. ENGLISH 11n GARAGING AND SCHEDULED MAINTENANCE Keep attention that all the nuts, screws and bolts are tightened in order to guarantee a good machine working on safety conditions. Leave the machine to cool before garaging anyhow don’t room it if the tank still contains some fuel as the vapours could reach some blazes or sparks. The fuel tank is to be drained outdoors only. To lower the re danger, keep the engine, the silencer and the fuel area free from leaves, grass or greasy substances. GEARBOX (Fig. 12, 13) Use SAE 80 oil. Oil capacity : 0,40 l. To check the oil level: the machine must be on level ground, Remove ller cap (1, Fig. 12) and check that the oil il level with the bottom of the hole. The ller cap acts also as the oil level. Check the oil level every 60 work hours. To change the oil: remove plug (1, Fig. 12) and tip the cultivator. Drain the oil when the engine is hot. When the oil has drained out completely, tip the machine back to its horizontal position and ll with new oil the bottom of the level hole. Replace the plug.(1,g.12). Remove the cap (2, g. 13), tip the cultivator and ll the gearbox with new oil up to the bottom of the level hole. Replace the plug. Change the oil every 150 work hours. ATTACHMENT COUPLE (Fig. 14) After use, clean and grease the couple (2) through the grease nipple (1). CUTTER BAR MAINTENANCE The cutter bar requires good and frequent maintenance. A rst and essential operation is to wash and clean the knife after each use. When the machine will not be used for long periods of time, the cutting bar and knife should be protected with corrosion inhibiting products and antioxidants. CHANGING THE CUTTING KNIFE (Fig. 15) To remove the top knife to change or sharpen it, remove screws (1) and pull the knife out with a pin push into hole (2). We recommend changing the knife after 2 or 3 sharpenings. The bottom knife should be changed after the cutting knife has been changed a coule of times though this will depend on the degree of wear. Always replace the plastic knife guide (3) when knifes are changed. SHARPENING THE CUTTING BLADE (Fig. 16) When the cutting blades are blunt (this will depend on work load) they must be reground. Do not exceed 15 hours of work. In orde to do this, the cutting blade is removed from the bar and cleaned. It is essential to check whether the backs and edges of the blades are bent; if so, they must be re-aligned. Only then can sharpening begin. Suitable for this purpose is a hand grinder with about 15000 - 20000 revolutions per minute, in conjunction with a cup-shaped grinding point with a diameter of 25 mm and a length of about 35 mm. Only the front side (face) of the grinding point is used in grinding in a movement from the back of the blade to the blade’s edges. Cutter bar blades need a cutting angle of 35 - 40°. CULTIVATOR MAINTENANCE (Fig. 17) Every time the rotary cultivator is used, the operator must check: -if the screws and nuts xing the right and left spiders to the shaft are tightened all the way home; - if all the screws and nuts xing the spades are tightened all the way home. Every 60 hours, check the oil in the gearbox by remove plug (1, Fig. 17). The oil must be level with the bottom of the hole. Change the oil every 150 work hours. To drain the oil, remove plug (1) and tip the cultivator over. Use SAE 80 oil. Drain the oil when the machine is hot. When the oil has drained out completely, tip the machine back to its horizo,tal position and ll with new oil the bottom of the level hole. Replace the plug. n DESCRIPTION (Fig. 18) 1) Start-Stop operating lever 2) Drive operating lever 3) Cutter bar clutching control lever 4) Engine 5) Lever to regulate the handlebar to the side. 6) Gear control rod.
