1.3.3 MAIN CHARACTERISTICS
1.3.4 RUNNING-IN
•
Simple and easy operation.
•
Hydrostatic transmission obtained through two variable displacement motors that operate epicyclic reduction
gears equipped with hydraulic brakes with negative control.
•
Upper structure rotation achieved through an axial piston hydraulic motor acting on an epicyclic reduction gear.
•
Lubrication of the ball-bearing ring toothing and of the pinion in grease bath.
•
Main equipment servo levers ensuring also combined movements that can be modulated proportionally and con-
tinually.
•
Boom swing and travel controls with servo assisted pedals that ensure proportional and continuous modulated
movements.
•
Travel speed increase by means of a button.
•
Servo controls also for the two-piece boom and the blade.
•
Complete series of instruments visible from the operating position.
•
Lever accelerator.
•
Easy maintenance with simplified intervals.
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 the start, let the engine 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 250 hours, carry out the following operations, in addition to those to be performed every 250 hours:
1 - Change the oil in the travel reduction gears.
2 - Change the oil in the swing reduction gear.
3 - Change the hydraulic circuit oil filter.
4 - Check and adjust the engine valve clearance.
SYNTHETIC BIODEGRADABLE OIL TYPE HEES
On machines in which the synthetic biodegradable oil type HEES is used, the following operations are to be per-
formed besides the standard maintenance operations:
•
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 innner part to make sure that there are no depos-
its.
If considerable deposits are observed, find out what may have caused them before starting the machine.
•
The number of operating hours is indicated by the Hour meter.
