SAFETY INSTRUCTIONS
External environmental
factors
Temperature
The ambient temperature, both heat and cold, affects
the machine’s operational reliability. Temperature
variations also have an impact as they produce an
increased risk of condensation forming in the ma-
chine’s tanks.
Heat
NB! There is an increased risk of overheating in warm
environments. Both the machine’s hydraulic system
and electronic components can be damaged.
The maximum working temperature for hydraulic fl uid
is 90°C (194°F). Overheating results in deposits form-
ing in the fl uid, leading to increased wear, damaged
seals and leakage. Overheated hydraulic fl uid pro-
vides poor lubrication, resulting in inferior perform-
ance.
To avoid overheating:
• Keep the machine clean, in particular its cooler.
• Ensure that there is good ventilation when working
indoors.
• Radiant heat can cause local heating that dam-
ages parts of the machine. Screen off vulnerable
components.
• Additional cooling is required if there are high
ambient temperatures. Supply the machine with
forced cooling using compressed air.
To avoid damage to the machine:
• Change hydraulic fl uid and fi lters more frequently.
• Check the machine’s seals to prevent dirt in the
hydraulic system due to broken seals.
• Rubber caterpillar tracks must not be exposed to
temperatures of over 70°C (158°F). In hotter envi-
ronments steel tracks have to be used.
Cold
Do not use maximum pump pressure if the hydraulic
fl uid is less than 10°C (50°F). Allow the machine to
warm up slowly. Warm up the lower section by run-
ning the caterpillar tracks, fi rst slowly and then more
quickly with the outriggers extended. Move the upper
section back and forth and operate all cylinders in the
arm system without load. The machine is ready for
use when its temperature has risen to around 40°C
(104°F).
Moisture
When working in damp environments the operator
should ensure that electrical components, connectors
for example, are not submerged in water.
The machine must never be driven to such a depth in
water that it reaches up to the machine’s equipment.
The equipment can be damaged and the machine can
be live, resulting in personal injuries.
Dust and particles
Dust and particles can block the machine’s cooler,
cause overheating and increase wear on the ma-
chine’s bearings and shafts. Clean and lubricate the
machine regularly.
The hydraulic system is extremely sensitive to con-
taminants. Small particles can cause breakdowns and
increase wear in the components.
There is a high risk of contamination in conjunction
with servicing and repairs when the hydraulic system
is opened.
Contamination of the hydraulic system can be
prevented by:
• Keeping the machine clean, particularly before
servicing, repairs or changing tools.
• Carrying out daily inspections.
• Carrying out regular servicing.
