SAFETY PRECAUTIONS
GENERALITIES
Read the Operation and Maintenance Instruction Manual 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
yellow 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 considerably 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, grabrails and handles clean and clear of foreign objects, oil,
grease, mud or snow to minimise the danger 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 contact
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 machine 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 operator’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 complete
stop.
Always check height, width and weight limitations which
may be encountered in the working site and ensure the
machine does not exceed them.
Assess exact paths of gas ducts, water mains, telephone lines, sewers, overhead and underground electric
lines and all other possible obstacles.
Such paths should be opportunely defined by
competent 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 upperstructure swing area and provide
for opportune barriers to prevent access into it.
STARTING
Never start or operate a failed machine. Walk all
around the machine before mounting.
Before operating the machine, make sure that any possible dangerous condition has been properly removed.
Before starting machine, check that steering and attachment controls are in the neutral position and the
safety lever is in the LOCK position. Immediately report
any malfunction of parts or systems 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 operating range. Sound the horn.

MANUALEQUIPOSPESADOS.COM
SAFETY PRECAUTIONS
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
someone enter the work area, stop the machine.
Maintain a safe distance from other machines or obstacles 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 cables.
Carefully inspect cables or chains for flaws or problems
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 using
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 properly protected against possible backlash in case of cable or
chain failure or detachment.
Be alert of soft ground conditions close to newly constructed 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 whatever
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 machine
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 machine control could result.
If noise level is high and exceeds 90 dB(A) over 8 hours
at the operator’s ear, wear approved ear protection 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
limits 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.
Always inspect the working area to identify potential
risks such as: inclines, overhangs, trees, demolition
rubble, fires, ravines, steep slopes, rough terrain, ditches, 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, ditches, railroad
tracks. When obstructions must be crossed, do so with
extreme care and at a square angle, 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 without risks.
The gradient you may attempt to overcome is limited by
factors such as ground conditions, load being handled,
machine type and speed, and visibility.
There is no substitute for good judgement and experience when working on slopes.
Avoid operating the attachment too close to an overhang
or high wall, either above or below the machine. Beware
of caving edges, falling objects and landslides. Remember that such hazards are likely to be concealed 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 that
could cause loss of control.
Work with extreme care on ice or frozen ground and on
stepped slopes or near drop-offs.
Never use the machine as a work platform or scaffolding.
The machine must not be improperly used for works not
consistent with its features (such as pushing railway
cars, trucks or other machines). Always pay attention to
people within the machine operating range.
Ground speed should be adequate to ground conditions.
- Nobody should be allowed to stand within the machine
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 features 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.

Keep the machine sufficiently far from the ditch edge.
Do not swing the upperstructure, raise the load or brake
abruptly if not required. This may cause accidents.
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 utilities
installations, appoint a person in charge of signalling
duties. This person will have the responsibility of observing the machine, any part of it and/or the load approaching the gas mains from a standpoint more favourable than the Operator’s. This signal man (flagman)
must be in direct communication with the Operator and
the Operator must pay undivided attention to the signals supplied.
- The gas distributing Company, if previously advised
and involved in the work, as well as machine Operator,
Owner and/or any natural person or legal entity having
rent or leased the machine or being responsible 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 observed.

standpoint more favourable than the Operator’s. This
signal man (flag-man) must be in direct communication
with the Operator and the Operator must pay undivided
attention to the 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.
Always check ground conditions and conditions of the
material to be removed. Support everywhere it is required to prevent possible cave-ins or landslides:
- near previous trenches filled with material, - in bad
ground conditions,
- when working trenches subject to vibration from railroads, working machines or highway traffic.

explosions and serious personal injuries.
TYRES AND WHEELS
Make sure that the inflation pressure of the tyres is
according to the specifications issued by the Manufacturer and check it periodically.
Should the pressure be changed, stand on the side of
the tyre at a safe distance.
Pressure check operations must be performed with
unloaded machine and cold tyres.
Never use reconditioned tyre rims, since eventual weldings, heat-treatments or repairs not performed correctly can weaken the wheel, thus causing subsequent
damages or dangers.
Do not perform torch cutting or welding operations on
rims with tyres installed.
