WORKSHOP MANUAL
Avoid kinking or twisting chains or cables.
Carefully inspect cables or chains for aws or problems before
proceeding.
Do not pull through a kinked chain or cable as the high anoma-
lous 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 pos-
sible backlash in case of cable or chain failure or detach-
ment.
Be alert of soft ground conditions close to newly constructed
walls. The ll 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 ter-
rain, 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 over-
head 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, res, ravines,
steep slopes, rough terrain, ditches, crowns, ridge trenches,
diggings in trac 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 ma-
chine 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 cav-
ing 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 adher-
ence or traction with the ground, especially near slopes or drop-
os.
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-os.
Never use the machine as a work platform or scaolding. 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 condi¬tions.
- Nobody should be allowed to stand within the machine op-
erating range for any reason whatever. Never exceed specied
loading capacity. Incorrect fastening of slings or chains may
cause boom/arm failure or failure of the lifting means with con-
sequent bodily injuries and even death.
Always ensure that slings and chains used for lifting are ad-
equate 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.
Working on slopes is dangerous. Grade the working area if pos-
sible. Reduce work cycle time if it is not possible to grade the
working area.
We recommend to work on slopes after checking machine sta-
bility.
Properly judge ground conditions with particular attention to
consistency of the area you are going to work on.
Keep the machine suciently 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 tel-
ephone directory.
- Dene together which precautions should be taken to guaran-
tee work safety.
- Decrease work speed. Reaction time could be too slow and dis-
tance evaluation wrong.
- When working near gas mains or other public utilities instal-
lations, 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
