INTRODUCTION 1.3.3 MAIN CHARACTERISTICS Simple and easy operation. Hydrostatic transmission obtained through a double variable displacement pump and axial piston motors operat- ing epicyclic reduction gears. Four driving wheels always engaged through oil-immersed roller chains. Main equipment and travel control through servo levers ensuring also combined movements that can be modu- lated proportionally and continually. Foot control for the optional equipment (if installed). Foot accelerator. Lever accelerator. Parking brake control. Complete series of instruments visible from the operating position. Easy maintenance with simplified intervals. Road travel (on request).
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. If the machine is subjected to excessive work load at the beginning of operation, its potential yield and its function- ality will be untimely reduced. Every new machine must be used carefully, paying special attention to the following indications: After starting the engine, let it idle for 5 minutes, in such a way as to warm it up gradually before actual operation. Avoid operating the machine with the limit loads allowed or at high speed.
Avoid abrupt starts or accelerations, useless sudden decelerations and abrupt reversals. After the first 50 hours of use, carry out the following operations, in addition to those to be performed every 50 hours: 1 - Check the gearing chain tension. 2 - Check the wheel nut tightening. After the first 250 hours of use, carry out the following operations, in addition to those to be performed every 250 hours: 1 - Change the hydraulic circuit drain filter. SYNTHETIC BIODEGRADABLE OIL TYPE HEES On machines in which the synthetic biodegradable oil type HEES is used, carry out the following operations in ad- dition to the routine maintenance:
After the first 50 hours of operation, change the hydraulic circuit drain filter. After the first 500 hours of operation, change the hydraulic circuit oil. IMPORTANT When changing the oil filters (cartridges), check their inner part to make sure that there are no deposits. If considerable deposits can be observed, find out what may have caused them before restarting the ma- chine. The number of operating hours is indicated by the hour meter. 5
