Respect the information supplied for maintenance and technical assistance.
Any maintenance operation must be carried out with the crane power source
turned off. (in case of fixed mounting with hydraulic power pack, the electric
motor has to be turned off).
Do not place limbs, fingers or any other parts of anatomy into areas of the
crane, which present possibilities of shearing, without having blocked such
parts of the crane.
Do not weld, drill or grind any part of the crane without the Manufacturer’s
authorisation.
Do not weld the fixing rods of the crane (see plate DE1574 fig. 1)
When repairs to, or checks of, the hydraulic circuit and of the rams are carried
out, it is very important not to use, or be in the proximity of, materials which
can damage the circuit or contaminate the hydraulic oil eg. metal shavings,
sand or dust.
Do not use the high pressure washing on the controls (deviators, distributors,
double controls, hand cable controls...), on the electronic components (boxes,
control panels...), on the tanks.
Never use detergents, petrolsol or inflammable liquids, always use non flam-
mable or non toxic liquids.
To avoid down time, it is recommended to periodically carry out the following
checks.
TIRANTI: NON SALDARE!
FIXING ROD: DO NOT WELD!
TIRANTS: NE PAS SOUDER!
ZUGSCHRAUBEN: NICHT SCHWEISSEN!
