INTRODUCTION
1.3.3 MAIN CHARACTERISTICS
• Simple and easy operation
• Hydrostatic transmission obtained through two axial piston motors that operate epicyclic reduction gears.
• Revolving frame swing archieved by means of an orbital hydraulic motor.
• Main equipment serv olevers ensuring also combined mov ements that can be modulated proport ionally and
continually.
• Pedal controls for the boom swing and the optional equipment.
• Lever controls for travel and blade.
• Travel speed increase by means of a pedal (optional for PC12R, standard on PC15R).
• Complete series of instruments visible from the operating position.
• Lever accelerator.
• Easy maintenance with simplified intervals.
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 hour s, in order to ensur e proper running- in of
the various components.
If the machine is subjected to excessive work load at the beginn ing of operatio n, 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 t he engine idle for 5 minutes, in such a way as to warm i t up gradual ly befor e actual op era-
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 hou rs, carry out the following ope rations, in addition to those to be performed every 250
hours:
1 - Change the oil in the travel reduction gears.
2 - Check and adjust the engine valve clearance.
SYNTHETIC BIODEGRADABLE OIL TYPE HEES
On machines in which the syn thet ic bio degrad abl e oi l ty pe HEES is used, the fol lo win g ope ra tio ns are to be performed 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 ar e observed, find out what may have caused them before star ting 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 good conditions; for this reason, 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 replacement of a component provided with a safety plate, make sure that this plate is applied also on
the new piece.
• The machine can be provided with other pl ates in addition to those indicated bel ow; keep also to the instruc-
tions given in the additional plates, in any case.

2.1.2 PICTOGRAMS AND RELEVANT MEANINGS
The warning and danger plates applied onto the machine are accompanied or represented by pictograms.
The personnel in charge with the operation and maintenance of the machine must know the symbols contained in
the pictograms perfectly; the following description illustrates what they look like and their respective meanings.
DANGER IN THE WORK AREA
• Do not approach or stand within the eq uip men t operating radi-
us when the boom and the bucket are raised.

DO NOT OPEN THE HOOD
• Do not open or remove the hood when the engine is running.
CONSULT THE MANUAL
• Carefully read the contents of the manual before using the ma-
chine or performing maintenance operations.

2.1.3 POSITION OF THE NOISE PLATES ON MACHINES WITH CAB
• The noise plates must always be legible and in good condi-
tions; for this reason, if they are dirty with dust, oil or grease, it
is necessary to clean them with a solu tion 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 replacement of a c omponent provided wi th a noise
plate, make sure that this plate is applied also on the new
piece.
NOISE OUTSIDE THE CAB
• This value indic ates the noise level outside the machine an d
refers to the noise pe rceived by persons i n the vicinity of the
work area.
NOISE INSIDE THE CAB (PC12R)
• This value indicates the maximum noise level perceived by the
operator’s ears inside the cab when this is completely closed.
