INTRODUCTION 1.3.3 MAIN CHARACTERISTICS Simple and easy to use. Cab (ROPS/FOPS level 2). Servo steering through hydraulic system with priority to steering needs. Three steering modes selected with push buttons: - Two-wheel steering (compulsory for travelling on roads) - Four-wheel steering (round steering) - Crab steering Selection of the machine operating mode (travel – travel + work - work). Gearshift with electronic selection of gears through solenoid actuators and transmission with hydraulic convert- er; reversal and speed change with controls on a single lever.
Boom lifting and equipment swinging control with servo lever that makes it possible to modulate the movements in a proportional and continuous way. Boom extension with potentiometer acting on a proportional solenoid valve. Safety valves for each movement of the cylinders. Controls and instrumentation visible form the work position. Accelerator pedal. Service brakes with foot control acting on the two axles. Simplified maintenance with reduced intervals. Independent controls for the stabilizers (optional). Frame levelling controlled through a water level (spirit level) and a rocker switch control with automatic return to the central position (optional). SLI-Safe Load Indicator.
Axle-frame lock that engages automatically when the boom inclination exceeds approximately 30° (optional). 1.3.4 RUNNING-IN Every machine is scrupulously adjusted and tested before delivery. A new machine, however, must be used carefully for the first 100 hours, in order to ensure proper running-in of the various components. Every new machine must be used carefully, paying special attention to the following indications: After the start, let the engine idle for 5 minutes, in such a way as to warm it up gradually before actual operation.
When warming the engine up, carry out some lifting cycles with an average load and extend the boom a few times, so that the hydraulic oil warms up more easily. Cover short distances at low speed to warm up the axles and transmission oil. Avoid operating the machine reaching the load limits allowed or at high speed. Avoid abrupt starts or accelerations, useless sudden decelerations and abrupt reversals, especially when travel- ling at the maximum speed allowed for each gear. After the first 250 hours of operation, besides the maintenance operations to be performed every 250 hours of operation, it is also necessary to: 1 - Change the transmission filter.
2 - Change the oil in the differential unit (front and rear axle). 3 - Change the oil in the final reduction gears (front and rear axle). 4 - Change the hydraulic circuit oil drain filter. 5
