1.2 INFORMATION ON SAFETY
Many accidents are caused by insufficient knowledge of and failure to comply with the safety regulations pre-
scribed for the maintenance operations that must be performed on the machine.
In order to avoid accidents, before starting work and before carrying out any maintenance operation, carefully
read and be sure to understand all the information and warnings contained in this manual and given on the plates
applied onto the machine, so that you can follow the instructions without making mistakes.
To identify the messages regarding safety that are included in this manual and written on the machine plates, the
following words have been used.
• This word is used in the safety warnings in the manual and on the plates when
the situation is dangerous and it may possibly result in serious injuries or even
death.
These messages describe the safety precautions to be taken in order to avoid
any risk. Non-compliance with these instructions may also result in serious
damage to the machine.
• This word is used in the safety warnings in the manual and on the plates to sig-
nal risks that may cause moderate damage or injuries.
The message can be used even to indicate the risk of damage to the machine
only.
• This word is used when precautions are indicated, which must be taken to avoid
actions that may shorten the life of the machine.
Komatsu Utility cannot reasonably predict every circumstance that might involve a potential hazard during the op-
eration or maintenance of the machine; for this reason, the safety messages included in this manual and applied
onto the machine may not include all possible safety precautions.
If all the procedures and operations prescribed for this machine are kept to, you can be sure that the operator and
the persons in the vicinity can work in total safety, with no risk of damaging the machine. In case of doubt regard-
ing the safety measures necessary for some procedures, contact Komatsu Utility or your local Dealer.
DANGER
•Before starting any maintenance operation, position the machine on firm and level ground, engage the
safety locks of the equipment and of the controls, stop the engine and apply the parking brake.
DANGER
•To make the information clearer, some illustrations in this manual represent the machine without safety
guards. Do not use the machine without guards and do not start the engine when the engine protection
casing is open, if this is not expressly prescribed for some specific maintenance operations.

1.3.3 MAIN CHARACTERISTICS
1.3.4 RUNNING-IN
•Simple and easy operation.
•Servo-assisted steering with priority hydraulic system.
•Gearshift with electronic gear selection through solenoid valve actuators and transmission with hydraulic con-
verter; reversal and gear shift with controls on a single lever.
•Loader control through a single lever ensuring also combined movements that can be modulated proportionally
and continually.
•Backhoe controls with two levers ensuring also combined movements that can be modulated proportionally and
continually.
•Complete series of instruments visible from the two operating positions (loader or backhoe).
•Separate accelerator controls for the two operating positions.
•Foot brake control.
•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 func-
tionality will be shortly and 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 opera-
tion.
•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 hydraulic transmission oil and filter.
2 - Change the differential unit oil (front and rear axle).
3 - Change the oil in the final reduction gears (front and rear axle).
4 - Check and adjust the engine valve clearance.
5 - Change the hydraulic circuit oil filter.
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 ma-
chine.
•The number of operation hours is indicated by the hour meter.
