7.1 DESCRIPTION OF ELEMENTS

SAFETY DEVICE All the motorcultivators are equipped with an accident prevention device. Such device causes the clutch release and the machine stopping on the single or reverse speed position, to the release of the control lever, furthermore such device avoids the reverse speed insertion if the single speed is on. CAUTION! If the machine is on reverse speed the rotavators are automatically stopping. CONTROLS DESCRIPTION

THREE-POSITION WHEEL CLUTCHING DEVICE: The cultivator is equipped with a special device called a “THREE-POSITION FORK”. - In position 1 (free), the wheel turns freely on the shaft so that the machine can move when the engine is stopped. - In position 2 (locked), the wheel is inte- gral with the shaft, setting into drive, mean- ing ready to start working. This is the most commonly used position. - In position 3 (semi-differential), the wheel can perform about a half-turn turning on the shaft, in order to allow turns. CAUTION! All operations on the three-position fork must be performed when the engine is at a standstill. DANGER!

Use caution when handling flammable fluids. Fuel is highly flammable and ex- plosive. Do not fill the tank in closed or poorly ventilated environments. Before refilling the tank, switch off the machine and wait until the motor has cooled down (15-20 min). Do not smoke or use electron- ic devices near combustible fluids. Use suitable, undamaged filling devices such as fuel cans, funnels, etc. In case of fuel leakage, move the ma- chine before starting it up. When filling operations have been com- pleted, replace the cap and tighten it firmly.

7.3 START-UP AND SHUT-DOWN

Check correct functioning of the main- tained action levers and double safety command before using the machine. See the “CABLE ADJUSTMENT” paragraph to make adjustments. It is forbidden to use the machine in case of malfunction of the controls. CAUTION! At the first use of the machine it is absolutely necessary to verify that inside the chassis is present the lubrication oil. Do no start the unit/machine on before having done such control. For additional information please look at the chapter GEARBOX 10.5. CAUTION! When you have finished the assembly, switch the machine and check, bringing the accelerator to the stop position, the engine shuts completely down. DANGER! DANGER! DANGER! DANGER! DANGER! DANGER! DANGER!

DANGER! CAUTION! Before switching the engine on, carefully check if the motorcultivator is in perfect good conditions.

Engine instructions: Carefully read the istructions booklet enclosed to the relevant engine. Check if the air filter is clean. Fill the tank in as per the fuel de- scribed in the engine specifications and using a filter filling funnel. Do not change the calibration of the speeds control rotation device of the engine in order not to over-speed it.

Put the fork into position 1 (free) so that the wheel could freely turn on the shaft to allow the movements.

3. Move the machine to the borders to be

Put the fork into position 2 (blocked) working position. Check if the gearbox control lever (Fig.

1.7 part 4 only 2+2 speed version) is on

loose position. Adjust the handlebar to the requested position/height.

How to switch the engine on: Open the fuel cap (for the engine equipped like this), push to halway the accelerator lever on the handlebar. If the engine is cold, operate the starter device on the carburetor.

6. Bring the starter handle

and pull energetically. When the engine is on, after some bursts/ bangs, put the starter again at rest position.

Grasp the handlebar, insert the speed (for 2+2 speed version) pos. A slow speed, pos. B fast speed (Fig. 1.7). At the beginning we recommend you to work on position 1, slow speed.

Forward speed: hold the handlebar, press the safety catch shown in the figure inwards and then pull the lever forward with its grip to its maximum stroke, meaning to its limit. The lever must be held down to maintain blade rotation. If you remove your hand, the lever will rise and automatically disengage blade rotation.

Reverse speed: let go of the clutch lever (Fig. 3.6) and, after having pressed the relative safety

3.7 located on the handlebar, raising

the back of the machine so that the Rotavator comes out of the ground until the machine starts to back up.

At the end of the work: when you finish the work, to stop the engine, bring the accelerator lever to the bottom gear. In case you have to face an unforeseen and accidental obstacle, you should immediately leave the two driving levers (Fig. 3.6, 3.7). In case of severe impact in case you find deformations or obvious damages, please go on changing all the knives and the corresponding pins with screws and tightening nuts. Ask to an authorized ser- vice centre.

8. HANDLING AND TRANSPORT

Before proceeding, read and understand the chapter “SAFETY INSTRUCTIONS” in its entirety. With the motor off, the machine can be moved by hand by pushing or pulling it from the handlebar. LIFTING:

When the machine is not going to be used for long periods of time, it is essential to protect the tool with anti-corrosion and antioxidant substances. Clean the machine of leaves and/or dirt before storage. DANGER! Remove the fuel from the tank and close the tap (if present). Park the machine on flat ground, removing the ignition key (if present) and/or spark plug cap. DANGER! Protect the sharp parts and cover the machine with protective sheets if neces- sary. DANGER! DANGER! DANGER!

Before proceeding, read and understand the chapter “SAFETY INSTRUCTIONS” in its entirety. Keep all nuts, bolts and screws tightened to ensure safe operation of the machine and/or interchangeable equipment in safe conditions.

10.1 DEPHT ADJUSTMENT

To ensure good milling and smooth move- ment of the cultivator, the Rotavator is equipped with a depth control device (7 Fig. 1.7) that adjusts the working depth of the hoes. Pull the control lever back and move it up or down to control ground penetration: the correct adjustment has been achieved when the machine moves at a constant speed and without jerking. - Hard soils cultivation: bring the depth control device to position (B). Such position corresponds to a small soil penetration. - Soft soils penetration: Bring the depth control device to position (A). Such position corresponds to a deep soil penetration depth. CAUTION! When moving with the machine in motion on surfaces other than the working ground, keep the depth control device in position (B); in this way, the hoe will not scrape the surface.

10.2 HANDLEBAR ADJUSTMENT

HEIGHT ADJUSTMENT: The height of the cultivator handlebar can be adjusted. Before starting any work it is a good standard operating procedure to adjust the handlebar to the operator’s re- quirements so that the machine could be easily handled. Loosen the handlebar sup- port fixing screws. Adjust to optimal height, tighten the screws.

LATERAL ADJUSTMENT: Lateral handlebar adjustment keeps the operator from stepping on ground that has already been hoed and from damag- ing vegetation. Lower the lever to unlock the handlebar. Rotate the handlebar from the desired side (positions possible: -35°, 0°, 35°) and raise the lever to lock it. DANGER!

Every 50 working hours, grease the reverse speed shaft with the suitable greaser, upon disassembling of rubber cap. CAUTION! Once such operation has finished you must close the hole again with the rubber cap because inside the casing there are some gears/parts on motion.

10.4 CABLE ADJUSTMENT

FORWARD/REVERSE LEVER: Attention: the wheels should start to turn when the driving lever has crossed half its way. When the mentioned lever is com- pletely pulled, on working position, the belt control device (8, Fig.1.7) must be arranged as in figure 4.6B, with the “cyl- inder” in contact with the two washers on the sides. To obtain the am conditions you have to act on the M10 nut set close near the belt control device (Fig. 4.6A).

OIL LEVEL CONTROL: Verify the oil level every 60 hours: put the machine on flat surface, remove the cap 1 and check if the oil reaches the hole bottom edge. In case you need to fill it on you have to perform it from the hole of the cap 2. Go on with such operation until you see the oil coming out from control cap 1. Screw both caps again. OIL CHANGE: Change the oil every 150 hours. The oil drain has to be performed when the ma- chine is hot: remove caps 1 and 2 and tilt the machine to a complete emptying, then put the machine on flat land, fill it in with oil through the hole of cap 2 until the oil starts coming out from control cap 1. Screw both caps again. Use a syringe (not included) for easier and safer extraction. Use SAE 80 or equivalent oil. CAUTION! Waste fuel oil is a polluting material: don’t waste it in the sorroundings, please apply to suitable waste material centres.

INFORMATION! CAUTION!en Do not use pressurised water to wash the machine and/or interchangeable equip- ment. Doing so can damage the motor and any electrical systems or batteries. Avoid excessive use of water near labels. In the event of damage, labels must be replaced before using the machine and/ or the interchangeable equipment again. CAUTION! CAUTION!

If the wheels are not full, we recommend checking tyre inflation before each ma- chine use. The recommended value is 21 PSI (1.5 bar). Before inflating the tyre, always check the maximum PSI value on the tyre.

11. CLEANING AND WASHING

Before proceeding, read and understand the chapter “SAFETY INSTRUCTIONS” in its entirety. Wait for all the hot parts to cool down (at least 20 minutes) before washing and/or cleaning the machine or the interchange- able equipment. Use compressed air or a sponge with neutral detergent and water. CAUTION! DANGER!
