- Page 9 INTRODUCTION SAFETY FEATURES FOUND IN THE MACHINE 1. Support stands: provide safe support of the front part of the machine when performing maintenance and ad- justments. 2. Safety chains: avoid lack of control over machine in case of accidental disengagement between the draw- bar of the Seeder and the drawbar of the tractor.
- Page 10 INTRODUCTION WARNING NOTES USED IN THIS MANUAL NOTE: This word indicates special technical instructions that, if not observed, can cause malfunction and eventually, damage to the machine. ATTENTION: This word indicates special technical instructions that, if not observed, can cause malfunction, damage to the machine and even risk of injury.
- Page 11 INTRODUCTION When removing, reinstalling or moving heavy assemblies • Always use appropriate devices to attach and lift whole and/or heavy assemblies. • Never stand under suspended loads. As safe as the lifting equipment may be, it is not worth running the risk! •...
- Page 12 INTRODUCTION • With the engine running: Do not touch or enter the seed or fertilizer box and not perform any repairs or adjust- ments, and also Do not access the supply platform. • Do not wear loose clothing, blankets or loose hair (if long), jewelery such as rings, bracelets and necklaces: moving parts could wind, pull and tear such items, with a risk of serious injury!
- Page 13 INTRODUCTION • Close all safety devices before starting the machine. This will prevent other materials from getting tangled on gears, chains, shafts and other moving parts of the system. SEM19101786 • Keep away from the articulated parts of the machine, such as row markers.
- Page 14 INTRODUCTION Care taken with hydraulic systems and fluids under pressure in general • Fluids escaping under pressure can penetrate the skin, causing injury and serious poisoning; fluids injected into the skin must be surgically removed as soon as possi- ble, as they may cause gangrene. •...
- Page 15 INTRODUCTION • Before disposing of used fluids and lubricants, always remember the environment: Do not pour or spill these products on the ground or water, or place them in con- tainers that could cause leaks. • Dispose of oils, solvents, paints and other products ad- equately, as established in the existing environmental legislation.
- Page 16 INTRODUCTION Welding work • Use the proper PPE for this activity: mask, gloves and a leather apron. • In case of electric welding: always seek to connect the negative electrode near the point to be welded. • Only perform welding in well ventilated areas to avoid the concentration of toxic gases and dust.
- Page 17 INTRODUCTION Basic instructions HITCH THE MACHINE ONTO THE TRACTOR CAUTION Transport hazard! Always connect a safety chain between the machine and the implement. Only use a safety chain with a strength rating equal to or greater than the gross weight of the implement. Failure to comply could result in minor or moderate injury.
- Page 18 INTRODUCTION Safety chain The chain (3) has the main function of safety in case of accidental disengagement of the machine. Engage the chain end (2) in the top link of the tractor's hitch system. The current (3) can be adjusted* to act as descent limiting of the lift arms, and therefore the drawbar (1).
- Page 19 INTRODUCTION HYDRAULIC SYSTEM Through the triple control valve (5) assembled on the machine frame, and the joystick type electric control (6), attached to the tractor, is possible to select the desired hydraulic function: • I — up / down the transport drive wheels. •...
- Page 20 INTRODUCTION Torque NOTE: The machines are designed with SI standard metric measurements. BAIL14SE00802AO NOTE: In case a special torque is specified for a given bolt or nut, do not use the values in the tables below. NOTE: When applying the recommended torque, make sure the threads are clean. NOTE: When replacing bolts and/or nuts, use new items with a class equal or superior to the original ones.
- Page 21 INTRODUCTION Recommended torque for steel hydraulic connections: 37° expansion connection Tube's external diameter / hose's internal diameter Thread size Torque in N.m 6.4 mm 1/4 in 7/16-20 in 8 -16 N.m 7.9 mm 11 - 22 N.m 5/16 in 1/2-20 in 9.5 mm 3/8 in 9/16-18 in...
- Page 22 INTRODUCTION Basic instructions INSTALLATION OF SNAP RINGS In the case of Seeger type rings (1) internal or external, installed and removed with pliers fitted in two holes (2) check for the correct side in the installation of the rings. This is because the holes (2) for fitting the pliers (3) are tapered: •...
- Page 23 INTRODUCTION BUSHING REPLACEMENT Bushing removal • Generally, bushings mounted under interference are re- moved only when they need to be replaced. • The removal can therefore be destructive. However, be careful not to damage the part where the bushing is mounted.
- Page 24 INTRODUCTION INSTALLATION OF SEALS IN HUBS WITH GREASE FITTING By introducing grease through the grease fitting (1), the old grease must be eliminated through the seal (2) In this case, check for the following: • Correct installation (2a): seal installed with the seal- ing lip turned out from the hub: the force of the grease moves the lip slightly away from the axis, allowing the outflow of the grease see indication by the arrows.
- Page 25 INTRODUCTION Seal installation procedure (with lip facing outwards) It is essential to use a tool (3) which supports the seal by its rigid base, without causing deformation or damage to the sealing lip. Move the seal until the rigid face reaches the bottom of the housing, but without forcing it.
- Page 26 INTRODUCTION Also analyze the state of the cage (4). If everything is in order, make a noise test (3) when rotat- ing the bearing with the hands, it cannot present metallic noises and its spinning must be completely smooth. The slightest irregularity in any of the above determines the replacement of the bearing.
- Page 27 INTRODUCTION REPLACEMENT OF ROLLER BEARINGS These bearings are usually made up of two parts: • Outer ring (or cup) (1). • "bearing cone" assembly (2), consisting of the inner track with the rollers (cylindrical or conical) and the cage. Thus, the removal and installation of tapered bearings is carried out in two parts: the cup and cone.
- Page 28 INTRODUCTION Heating or cooling of parts installed with interference • In the case of bearings, it is a good practice to heat them for their installation. The expansion of the heated parts reduces the force needed for installation, facilitating the procedure and reducing the chance of damage to them.
- Page 29 INTRODUCTION IDENTIFYING THE CAUSE OF FAILURE BEFORE DISASSEMBLY • Whenever possible, focus on making the complete di- agnosis of the problem before starting disassembly. • Take the necessary time for good previous planning, avoiding unnecessary operations and/or part replace- ments. •...
- Page 30 INTRODUCTION • Use wrenches correctly: see in the figure the correct direction of application of force on the lever relative to the angle of the socket (1). • Work in the opposite direction causes a greater effort in the structure of the key. Use this procedure only in special cases, such as bolts which are hard to access: in this case, switch positions, not recommended (X) and recommended (C) of the key until loosening the bolt.
