Komatsu machines are constructed exclusively for the handling, excavation and treatment of inert materials; there-
fore, the following uses are absolutely forbidden:
q
USE OF THE MACHINE BY MINORS OR INEXPERIENCED PERSONS.
q
USE OF THE MACHINE FOR THE LIFTING OF PEOPLE.
q
TRANSPORT OF CONTAINERS WITH FLAMMABLE OR DANGEROUS FLUIDS.
q
USE OF THE BUCKET FOR DRIVING OR EXTRACTING PILES.
q
USE OF THE MACHINE FOR TOWING DAMAGED VEHICLES.
1.3.4 MAIN CHARACTERISTICS
q
Simple and easy operation.
q
Hydrostatic transmission obtained through two axial piston motors that operate epicyclic reduction gears.
q
Rotation of the turret achieved by means of an axial piston hydraulic motor acting on an epicyclic reduction gear.
q
Main equipment controlled through servo levers ensuring also combined movements that can be modulated pro-
portionally and continually.
q
Boom swing and optional equipment operated through foot pedal controls.
q
Travel and blade operated through levers.
q
Travel speed selection push button.
q
Hydraulic track gauge adjustment (optional).
q
Complete series of instruments visible from the operating position.
q
Lever accelerator.
q
Easy maintenance with simplified intervals.
1.3.5 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 productivity and its
functionality will be shortly and untimely reduced.
Every new machine must be used carefully, paying special attention to the following instructions:
q
After the start, let the engine idle for 5 minutes, in such a way as to warm it up gradually before actual operation.
q
Avoid operating the machine with the limit loads allowed or at high speed.
q
Avoid abrupt starts or accelerations, useless sudden decelerations and abrupt reversals.
SYNTHETIC BIODEGRADABLE OIL TYPE HEES
For machines in which synthetic biodegradable oil type HEES is used, perform the following operations in addition
to the standard maintenance operations:
q
After the first 50 hours of operation, change the hydraulic circuit drain filter.
q
After the first 500 hours of operation, change the hydraulic circuit oil.
q
When changing the oil filters (cartridges), check their inner part to make sure that there are no deposits.
If considerable deposits are observed, find out what may have caused them before starting the machine.
q
The number of operating hours is indicated by the hour meter.
