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 function­ality 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 hou rs of use, carr y out the following opera tions, in addition t o those to be p erformed 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 ad­dition 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.
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 ma­chine.
The number of operating hours is indicated by the hour meter.

2.1 SAFETY, NOISE AND VIBRATION PLATES

2.1.1 POSITION OF THE SAFETY PLATES

The safety plates must always be legible and in go od co ndi tio ns ; for this reas on, if they are dirty with dust, oil or
grease, it is necessary to clean them with a solution made of water and detergent. Do not use fuel, petrol or solvents.
If the plates are damaged, ask for new ones to Komatsu Utility or to your Komatsu Utility Dealer.
In case of replace men t o f a co mpo nent provided with a safety plate, ma ke sure that thi s pl ate is applied also on
the new part.
The machine can be provided with other plates in addition to those indicated below; in any case, keep also to the
instructions given in the additional plates.

2.1.2 PICTOGRAMS AND RELEVANT MEANINGS

The warning and danger plates applied on to the machine are accompanied or represented by pictograms. The personnel in char ge wi th th e ope ration and maintenance of the mac hi ne must know th e symb ol s c ont ain ed i n the pictograms perfectly; the following description illustrates what they look like and their respective meanings.
DANGER IN THE WO RK AREA (Only for machines with excavator)
Do not approach or stand within the equipment operating radius
when the boom and the bucket of the excavator are raised.

2.1.3 POSITION OF THE NOISE PLATES

The noise plates must always be legible and in good conditions;
for this reason, if they are dirty with dus t, oil or greas e, it is ne c­essary to c lean them with a solution made of water and deter­gent. Do not use fuel, petrol or solvents.
If the plates are damage d, ask for new ones to Komatsu Utility
or to your Komatsu Utility Dealer.
In case of rep lacement of a component provided with a noise
plate, make sure that this plate is applied also on the new part.

2.1.4 VIBRATIONS TO WHICH THE OPERATOR IS SUBJECTED

According to the results of the tests carried out to determine the vibrations transmitted to the operator by the ma-
chine, the upper limbs are subj ected to v ibrations lower than 2.5 m /sq.s ec., wh ile th e sea ted part of the bo dy is subjected to vibrations lower than 0.5 m/sq sec.

GENERAL PRECAUTIONS

2.2 GENERAL PRECAUTIONS

2.2.1 GENERAL SAFETY RULES

Only trained and authorized personnel can use the machine and perform maintenance operations.
When using the m achine or pe rforming maint enance op erations, follow all the safety rul es, precautions and in-
structions.
When working with o ther operators or when the wor k site is often occupied by other o perators, make sure that
everyone knows and understands all the agreed sign als and , in any ca se, th at everyone works in such a way as to be able to see the machine and to be visible to the operator.

2.2.2 SAFETY DEVICES AND GUARDS

Make sure that all the guards and c overs are in the correct position. Have guards and covers changed or re-
paired if damaged. Neither use the machine without guards, nor remove the guards when the engine is running.
Always use the proper safety devices to lock the machine when parking and remember to fasten the safety belt.
For the safety devices, see 3.1 SAFETY LOCKS”.
For the safety belt, see 3.5.6 SAFETY BELT”.
Do not remove the safety devices and always keep them in good operating conditions.
Improper use of the safety devices may lead to serious injuries or even death.
2.2.3 CLOTHING AND PERSONAL PRO­TECTION ITEMS
Do not wear large or loose clothes, rings and watches and do
not approach the machine with loose long hair, since they can get entagled in the moving parts of the machine and cause seri­ous injuries and damage. Avoid also wearing clothes dirty with oil or fuel, since they are flammable.
Wear a hard hat, goggles, safety shoes, mask, gloves and head-
phones when operating the machine or performing maintenance operations.
Always wear safety goggles, a hard hat and heavy gloves if your
job involves scattering metal chips or minute materials; these precautions are particularly useful when driving the equipment connection pins with a hammer and when blowing compressed air into the air filter and the radiator to clean them. During these operations, make also sure that no one is standing or working near the machine without the necessary protections.
When working for 8 hours with a noise lev el exceeding 90 dBA, it
is necessary to use headphones or ear plugs and to be particu­larly careful, especially at the end of the work shift.

2.2.4 UNAUTHORIZED MODIFICATIONS

Any modification made without the authorization of Komatsu Utility can involve hazards.
Before making a modification, consult your Komatsu Utility Dealer. Komatsu Utility declines any responsibility for
injuries or damage caused by unauthorized modifications.

2.2.5 LEAVING THE OPERATORS SEAT

When leaving the operatorís seat, even if temporarily, make
sure that the machine is in a safe position (see 2.4.11 PARK­ING THE MACHINE”).
Before leaving the operatorís seat, carr y out the following oper-
ations in the sequence indicated below: 1 - Rest the equipment on the ground.
RWA31780
2 - Apply the parking brake.
3 - Engage the safety device of the optional equipment c ontrol
pedal (if installed).
RWAA11160
RWAA12610
4 - Lock the equipment and travel control by shifting the sa fety
bars to the lock position.
5 - Stop the engine (see 3.8 STOPPING THE ENGINE”).
If you have to go so far away that you will not be able to see the machine, extract the ignition key.
