INTRODUCTION
AVOIDACCIDENTS
The majority of accidents and injuries which occur in plants, in farms and at
home or on roads, are caused by the non-observance of some simple and
fundamental rules of precaution and safety. For this reason in the MAJORITY
OF CASES THEY CAN BE AVOIDED: it is sufficient to foresee possible
causes and to act according with the necessary precaution and care.
With any type of machine, as much as good planned or built, it is impossible
to absolutely avoid risks of accidents without involving negatively some
essential features for a reasonable access and an efficient operation.
Read carefully the indication and cautions of this manual contained in the
SECTION “SAFETY PRECAUTIONS”.
A careful and cautious operator is the best warranty against accidents.
The careful observation of a single and elementary safety precautions would
be enough to avoid many serious accidents. This precaution is:
Never attempt any cleaning, lubrication or maintenance operation when
machine is moving.
YYYS WARNINGYYY
Before carrying out any maintenance operation, adjustment and or repair
on machines equipped with attachments, controlled hydraulically or
mechanically, make sure that the attachment is lowered and safely set on
the ground. If in oder to get access to a machine part it is necessary to
hold the attachment lifted, this should duly be supported by means that
are not use to control the machine.

SSAFETY PRECAUTIONS
SAFETY PRECAUTIONS
GENERAL NOTES
Read the Operation and Maintenance Instruction Man-
ual carefully before starting, operating, maintaining,
fuelling or servicing the machine.
Carefully read the explanation to each and all safety
signs in the special section of this Manual before
starting, operating, maintaining, fuelling or servicing
the machine.
Machine-mounted safety plates are colour coded yel-
low with black borders when they refer to points
where special ATTENTION must be paid and failure
to observe them may cause a serious DANGER to
the integrity of machine operators.
They are white with red borders and black lettering
when they refer to a FORBIDDEN practice.
It is fundamental that all machine operators know very
well the meaning of each safety plate as this consid-
erably decreases operating hazards and accidents.
Do not allow unauthorised personnel to operate or
service this machine.
Do not wear rings, wrist watches, jewellery, loose or
hanging garments, such as ties, torn clothing,
scarves, unbuttoned or unzipped jackets that can get
caught in moving parts. Wear certified safety clothes
such as: hard hat, no-slip footwear, heavy gloves, ear
protection, safety glasses, reflector vests, respirators
every time the job requires it.
Ask your employer about safety regulations in force
and protective equipment.
Always keep the operator’s compartment, step plates,
grab-rails and handles clean and clear of foreign ob-
jects, oil, grease, mud or snow to minimise the dan-
ger of slipping or stumbling. Remove mud or grease
from your shoes before operating the machine.
Do not jump on or off the machine. Always keep both
hands and one foot, or both feet and one hand in con-
tact with steps and/or grab rails.
Do not use controls or hoses as hand holds. Hoses
and controls are movable parts and do not provide
solid support. Besides, controls may be inadvertently
moved and cause unexpected movement of the ma-
chine or its attachments.
Never operate the machine or its attachments from
any position other than sitting in the driver’s seat.
Keep head, body, limbs, hands and feet inside the op-
erator’s compartment at all times to reduce exposure
to external hazards.
Be careful of possible slippery conditions of the steps
and hand rails as well as of the ground around the
machine. Wear protective boots or shoes with the
soles made of highly no-slip rubber.
Do not leave the machine until it has come to a com-
plete stop.
Always check height, width and weight limitations
which may be encountered in the working site and en-
sure the machine does not exceed them.
Assess exact paths of gas ducts, water mains, tele-
phone lines, sewers, overhead and underground elec-
tric lines and all other possible obstacles.
Such paths should be opportunely defined by compe-
tent Authorities. If necessary, require that the service is
interrupted or said installations are moved prior to
starting the work.
You must know the working capacity of the machine.
Define the rear superstructure swing area and provide
for opportune barriers to prevent access into it.
Never exceed machine lifting capacity.
Remain within the limits shown in the loading capacity
chart located on the machine.
START UP
Never start up or set in motion a failed machine.
Before getting on, walk around the machineto in-
spect it. Before operating the machine, make sure
that any possible dangerous condition has been prop-
erly removed.
Before starting machine, check that steering and at-
tachment controls are in the neutral position and the
safety lever is in the LOCK position.
Immediately report any malfunction of parts or sys-
tems to the maintenance managers for proper action.
Prior to starting the engine, check, adjust and lock the
driver’s seat for maximum riding comfort and control
accessibility.
Prior to operating the machine and/or its attachments,
check that bystanders are outside the machine oper-
ating range. Sound horn.
Obey all hand signals, safety indications and signs.
Due to the presence of flammable fluids, never
check fuel level, refuel, charge the batteries or use
the starting fluid in the presence of smoking materi-
als, open flames or sparks.
Ensure that nobody is within the excavator operating
area before starting the machine, swinging the upper
structure or moving in any direction.
Adjust all rear-view mirrors for maximum visibility of
the area behind the machine.
Ensure that engine speed is appropriate to the job to
be carried out.
If any hydraulic control or system exhibits erratic per-
formance or responds abnormally, have the machine
checked for air in the system.
Air in these circuits may cause incorrect movements
with consequent accident hazard.
Refer to the Operation and Maintenance Instruction
Manual about corrective action to be taken.

2-2
SSAFETY PRECAUTIONS
OPERATION
Do not run the engine of this machine in closed build-
ings without proper ventilation capable to remove
harmful exhaust gases which concentrate in the air.
Keep the driver’s seat free from foreign objects, es-
pecially if these are not secured. Never use the ma-
chine to transport objects, unless proper securing
points are provided.
Do not carry riders on the machine.
Study and familiarise with escape routes alternative
to normal exit routes.
For your personal safety, do not climb on or off the
machine while it is in motion.
Make sure that bystanders are clear of the machine
operating range before starting the engine and operat-
ing the attachment. Sound horn.
Obey all hand signals, safety indications and signs.
When backing, always look to where the machine is
to be moved.
Be alert of the position of bystanders. Should some-
one enter the work area, stop the machine.
Maintain a safe distance from other machines or ob-
stacles to ensure required visibility conditions.
Always give way to loaded machines.
Maintain a clear vision of the surroundings of the
travel or work area at all times.
Keep cab windows clean and repaired.
When pulling loads or towing through a cable or
chain, do not start suddenly at full throttle. Take-up
slack carefully. Avoid kinking or twisting chains or ca-
bles.
Carefully inspect cables or chains for flaws or prob-
lems before proceeding.
Do not pull through a kinked chain or cable as the
high anomalous stresses existing in this condition
may induce failures in the kinked portion. Always wear
heavy gloves when handling chains or cables.
Chains and cables should be securely anchored us-
ing suitable hooks. Anchor points should be strong
enough to withstand the expected load.
Keep anyone clear of anchor points and cables or
chains. Do not pull or tow unless the operator’s
compartments of the machines involved are prop-
erly protected against possible backlash in case
of cable or chain failure or detachment.
Be alert of soft ground conditions close to newly con-
structed walls. The fill material and machine weight
may cause the wall to collapse under the machine.
In darkness, check area of operation carefully before
moving in with the machine. Use all lights provided.
Do not move into low visibility areas.
If the engine tends to slow down and stall for whatev-
er reason under load or at idle, immediately report
this problem to the maintenance managers for proper
action. Do not operate the machine until this condition
is corrected.
Regularly check all exhaust system components, as
exhaust fumes are toxic for the operator.
Operators must know the performance of the ma-
chine they are driving.
When working on slopes or near sudden level drops
in the terrain, pay attention not to lose adherence and
avoid loose soft ground since overturn or loss of ma-
chine control could result.
If noise level is high and exceeds 90 dB(A) over 8
hours at the operator’s ear, wear approved ear pro-
tection in compliance with local regulations.
Do not operate the machine if you are extremely tired
or feel ill.
Be especially careful towards the end of the working
shift.
Where removable counterweights are provided, do
not operate the machine if they have been removed.
When operating the machine, keep in mind height lim-
its of overhead doors, arches, overhead cables and
lines as well as width limits of corridors, roads and
narrow passages. Also, get to know load limits of the
ground and paving type of the ramps you are to work
on.
Beware of fog, smoke or dust that obscure visibility.
Check constantly the work areas to find out the dan-
gerous points. Some examples of dangerous work ar-
eas are: inclines, overhangs, trees, demolition rub-
ble, fires, ravines, steep slopes, rough terrain, ditch-
es, crowns, ridge trenches, diggings in traffic areas,
crowded parking lots, crowded service areas, fenced
zones. In such conditions, proceed with extreme
care.
Whenever possible, avoid crossing over obstacles
such as very rough terrain, rocks, logs, steps, ditch-
es, railroad tracks. When obstructions must be
crossed, do so with extreme care and at a square an-
gle, if possible.
Slow down. Ease up to the break-over point, pass the
balance point slowly and ease down the other side
also using the attachment, if necessary.
To overcome deep trenches or sinking ground, place
the machine perpendicular to the obstacle, drastically
reduce ground speed and start crossing using also
the attachment if necessary, only after assessing that
ground conditions allow the traverse safely and with-
out risks.
The gradient you may attempt to overcome is limited
by factors such as ground conditions, load being han-
dled, machine type and speed, and visibility.
There is no substitute for good judgement and experi-
ence when working on slopes. Avoid operating the at-
tachment too close to an overhang or high wall, ei-
ther above or below the machine. Beware of caving
edges, falling objects and landslides.
Remember that such hazards are likely to be con-
cealed by bushes, undergrowth and such.
Avoid faggots, bushes, logs and rocks. Never drive
over them, nor over any other surface irregularities
that discontinue adherence or traction with the
ground, especially near slopes or drop-offs.
Be alert to avoid changes in adherence conditions

2-3
SSAFETY PRECAUTIONS
that could cause loss of control. Work with extreme
care on ice or frozen ground and on stepped slopes
or near drop-offs.
The word “bulldozing” generally refers to work in vir-
gin rough terrain, characterised by the presence of all
the perils and risks listed above. We emphasise the
danger represented in these conditions by large tree
limbs and large roots,which may act as a leverage
under the machine when up-rooted and cause their
overturn. Position the machine according to the load-
ing and unloading areas in order to slew leftwards to
load and to obtain best visibility.
Never use the bucket or attachment to lift per-
sons or carry riders on the machine.
Never use the machine as a work platform or scaf-
folding. The machine must not be improperly used for
works not consistent with its features (such as push-
ing railway cars, trucks or other machines).
Always pay attention to people within the machine op-
erating range.
Never move or stop the bucket, other loads or the at-
tachment above ground personnel or truck cabs.
Before loading a truck make sure that the driver finds
a safe place. Load trucks from side or rear. Use only
the type of bucket recommended considering ma-
chine type, materials to be handled, material piling up
and loading characteristics, ground type and other
typical conditions of the work to be performed. When
travelling with a loaded bucket, keep it as rolled-back
as possible.
Ground speed should be adequate to the load and
ground conditions. The load must always be properly
arranged in the bucket. Move with extreme care when
transporting oversize loads.
Do not lift and move the bucket overhead where per-
sons are standing. When working on slopes avoid
travelling with bucket downhill because this could re-
duce the machine stability. Load the bucket from up-
hill side. Loads to be raised using the machine should
be exclusively hooked to the hitch specially provided.
The excavator is no lifting and transportation means,
therefore it should not be used to position loads accu-
rately. Should it be exceptionally used to lift and lay
building components, special caution must be taken
as follows:
• The machine should necessarily be equipped with
the special option supplied by Dealer. Besides, fol-
low carefully safety rules for the excavator used as
lifting means.
• Secure the loads to be raised using cables or
chains fastened with appropriate hooking mecha-
nisms.
• Nobody should be allowed to remain under the
raised load or within the excavator operating range
for any reason whatever.
Never exceed specified loading capacity. Incorrect
fastening of slings or chains may cause boom/arm
failure or failure of the lifting means with consequent
bodily injuries and even death.
Always ensure that slings and chains used for lifting
are adequate to the load and in good condition.
All loading capacities are referred to the machine
on a level surface and should be disregarded
when working on a slope.
Avoid travelling across slopes. Proceed from uphill
downhill and vice-versa.
If machine starts slipping sideways when on a slope,
lower the bucket and thrust bucket teeth into the
ground.
Working on slopes is dangerous. Grade the working
area if possible. Reduce work cycle time if it is not
possible to grade the working area.
Do not move full bucket or a load from uphill downhill
as this would reduce machine stability.
Do not work with the bucket turned uphill as counter-
weights protruding downhill would reduce machine
stability on the slope and increase risk of overturning.
We recommend to work on slopes with the bucket
downhill, after checking machine stability with the
bucket empty and attachment retracted, by slowly
swinging the upper structure by 360°.
Position the carriage at a right angle relative to
slopes, hanging walls, etc. to exit the working area
easily. Be aware when the upperstructure is turned by
180°, steering and travel controls are reversed.
Properly judge ground conditions with particular atten-
tion to consistency of the area you are going to work
on. Keep the machine sufficiently far from the digging
border.
Never dig under the machine.
Should it be necessary to dig under the machine, al-
ways ensure that digging walls are opportunely
propped up against landslide to prevent the machine
from falling into the trench.
Do not slew the upper structure, raise the load or
brake abruptly if not required. This may cause acci-
dents.
Prior to beginning the work near gas distribution
mains or other public utilities:
• Contact the Company Owner of the gas mains or its
nearest branch before starting the work. Look up the
number in the telephone directory.
• Define together which precautions should be taken
to guarantee work safety.
• Decrease work speed. Reaction time could be too
slow and distance evaluation wrong.
• When working near gas mains or other public utili-
ties installations, appoint a person in charge of sig-
nalling duties. This person will have the responsibili-
ty of observing the machine, any part of it and/or the
load approaching the electric line from a better
standpoint with respect to the Operator’s position.
This signal-man shall directly communicate with the
Operator and the Operator must pay special atten-
tion to any signals supplied.
• The gas distributing Company, if previously advised
and involved in the work, as well as machine Opera-
tor, Owner and/or any natural person or legal entity

2-4
SSAFETY PRECAUTIONS
having rent or leased the machine or being respon-
sible at the time by contract or by law, are liable
for the adoption of the necessary precautions.
Working near electric lines can be very dangerous,
therefore some special precautions must be ob-
served. Within this Manual, “work near electric lines”
means when the attachment or load raised by the ex-
cavator (in any position) may reach the minimum
safety distance established by local or international
Safety Regulations.
To work without risks, keep maximum possible dis-
tance from electric lines and never trespass minimum
safety distance.
Ensure that local or national safety regulations con-
cerning work near electric lines are observed.
Prior to beginning the work near electric lines:
• Contact the Company Owner of the electric lines or
its nearest branch before starting the work. Look up
the in the telephone directory.
• Define together with the Company representative
which precautions should be taken to guarantee
work safety.
• All electric lines should be considered as operative
live lines even though it might be well known that the
line in question is out of work and visibly connected
to the ground.
• The Electric Power Company, if previously advised
and involved in the work, as well as machine Opera-
tor, Owner and/or any natural person or legal entity
having rent or leased the machine or being responsi-
ble at the time by contract or by law, are liable for the
adoption of the necessary precautions.
• Decrease work speed. Reaction time could be too
slow and distance evaluation wrong.
• Warn all ground personnel to keep clear of the ma-
chine and/or load at all times. If the load has to be
guided down for laying, consult the Electric Power
Company to know which precautions should be taken.
• Appoint a person in charge to signal instructions.
This person will have the responsibility of observing
the machine, any part of it and/or the load ap-
proaching the electric line from a better standpoint
with respect to the Operator’s position. This signal-
man shall directly communicate with the Operator
and the Operator must pay special attention to any
signals supplied.
When working in or near pits, in ditches or very high
walls, check that the walls are sufficiently propped up
to avoid cave-in hazards.
Pay the utmost attention when working near overhang
walls or where landslides may take place. Make sure
that the support surface is strong enough to prevent
landslides.
When digging, there is the risk of cave-ins and land-
slides.
Always check ground conditions and conditions of the
material to be removed. Support everywhere it is re-
quired to prevent possible cave-ins or landslides
when:
• When digging near recently formed trenches filled
with filling materials.
• When digging in bad ground conditions.
• When digging trenches subject to vibration from rail-
roads, working machines or highway traffic.
STOP
When the machine is to be stopped for whatever rea-
son, always check that all controls are in the neutral
position and that the safety lever is on the lock posi-
tion to guarantee risk-free start-up.
Never leave the machine unattended with the engine
running.
Before leaving the driver’s seat and after ensuring no-
one is near the machine, slowly lower the attachment
until it rests safely onto the ground. Move possible ad-
ditional tools in the safe retracted position. Check that
all controls are in the neutral position. Move engine
controls to the shut-down position. Switch off the key-
start switch. Consult the Operation and Maintenance
Instruction Manual.
Park the machine in a non-operating and no-traffic
area. Park on firm level ground. If this is not possible,
position the machine at a right angle to the slope,
making sure there is no danger of uncontrolled slid-
ing.
If parking in traffic lanes cannot be avoided, provide
prescribed danger signals such as: flags, barriers,
flares and other signals. Moreover arrange further
danger signals on traffic lane so as to adequately
warn the oncoming drivers.
Always switch off the key-start switch before clean-
ing, repairing or servicing, or parking the machine to
prevent accidental unauthorised start-up.
Never lower the attachment or auxiliary tools other
than from sitting in the operator’s seat. Sound horn.
Make sure that nobody is within the machine operat-
ing range. Lower the attachment slowly.
Securely block and lock the machine every time you
leave it unattended. Return keys to the safe place
previously agreed upon.
Perform all necessary operations for stopping as de-
tailed in the Operation and Maintenance Instruction
Manual.
Drive the machine far from pits, trenches, rocky
hanging walls, areas with overhead electric lines, and
slopes before stopping it at the end of the working
day.
Align the upperstructure to the tracks in order to allow
to easily get on and off the driver’s compartment.
Move all controls to the position specified for machine
stopping. Refer the Operation and Maintenance In-
struction Manual.
Never park on an incline without accurately blocking
the machine to prevent unexpected movement.
Always follow stopping instructions contained in the
Operation and Maintenance Instruction Manual.
