Page 6: To The Operator
To the operator Be careful with the environment Dear operator! Respect the ecology. Do not throw trash away. This gesture of goodwill helps to protect our environment. Products such as oil, fuel, filters, batteries and others are spilt over the soil and can penetrate to the underground layers, compromising nature. - Page 7 To the operator Never use your bare hands to check hydraulic leaks, the high pressure can cause injuries. Never attempt to change the adjustments, clean or lubricate the equipment when the same is switched on or in movement. Be careful while driving on slopes. Risk of overturn. Prevent that chemical products (i.e.: fertilizers, treated seeds) make any contact with your skin or clothes.
- Page 8 To the operator • Only trained and qualified personnel are allowed to operate the equipment. • While working or during transportation, only the presence of the operator is allowed in the tractor. • Do not allow children to play or to get over the equipment while it is operating, during transportation or storage.
- Page 9 To the operator Transportation over truck or trailer Marchesan does not advise the equipment traffic on highways, because this practice involves serious security risks in addition to being prohibited by the current existing traffic law.

Page 27: Set-Up Instructions
Set-up instructions The following instructions must be carefully observed in order to get the best working performance. Preparing the tractor The addition of water ballasts in the tires and a set of weights on the front part and rear wheels of the tractor are the most used ways to increase the soil traction and give greater stability to the tractor. -
Page 28: Hitching To The Tractor
Set-up instructions Hitching to the tractor (hydraulic motor) Approach the tractor and couple the hoses (A) to the quick couplers. To do so, shut down the engine, relieve the control valve pressure by activating the lever a couple of times and check if the quick couplers are clean. - Page 29 Set-up instructions Hitching to the tractor Couple the hitch (A) to the tractor drawbar by placing a pin (B) and cotter pin. To facilitate hitching, use the jack (D) height adjustment. Fasten the chain (C) to the equipment and tractor to assure that the set will not get loose, but leave a small clearance to assure that the equipment can perform maneuvers.
- Page 30 Set-up instructions Coupling the cardan to the PTO Verify the length of the cardan shaft in the following way: 1) Separate the male bar from the female tube and couple it in the power take-off. For this, turn the quick lock on clockwise direction and push it to fit on the coupling lock device.

Page 31: Reducing The Cardan Shaft Length
Set-up instructions Reducing the cardan length If it is necessary, cut similar parts of the male and female drive shaft as well as the protecting covers. But before cutting the shaft, verify all possibilities of usage without reducing its length. The length adjustment will be done when the distance between the equipment and the tractor do not allow coupling. - Page 32 Set-up instructions Cardan shaft assembly When assembling the cardan shaft, it is necessary to be careful and leave the terminals on both ends aligned. The discrepancy of the terminals in 90° will cause vibrations and a greater wear on the universal joints, reducing the lifetime of the set. Observe the internal forks alignment Correct assembly Correct assembly...

Page 33: Jack Position For Working Or Transportation
Set-up instructions Jack position for working or transportation After hitching, the jack (A) must be removed. To do so, release the cotter pin (B) and pin (C). Remove the jack and place it on the frame side using a pin (C) and cotter pin (B), as shown below. - Page 34 Set-up instructions Equipment leveling Couple the drawbar and check the horizontal leveling of the equipment. If there is any adjustment that needs to be done, proceed as follows: Consult the tractor manual to check the possible drawbar working positions. Use a height that will better help leveling the equipment.

- Page 56 Maintenance Filtering element replacement indicator The main function of the pressure filters is to protect complex systems or critical particle components that may cause damages or the malfunction of valves or hydraulic motors, what would reduce the equipment durability. The contamination indicators help to monitor the filter. As the contamination on the filtering element increases, the loss of pressure on the filter carcass rises.
- Page 57 Maintenance Replacing the filtering element The filtering maintenance (A) of the equipment, as well as its replacement on the hydraulic system, is essential to assure a good functioning of the system. Usually, this replacement is done every third month or on a predefined interval stated by the filter manufacturer.
