22 MAINTENANCE INSTRUCTIONS
22.1 Generality
To assure a long life to the crane, it is necessary to meticulously follow the
maintenance instructions.
General lubrication and small repairs can be carried out by the user; repairs of
a more complicated nature must be carried out by authorized service person-
nel.
Spare parts must be original.
Good maintenance and proper use are imperative to maintain efficient use and
guarantee the safety of the crane.
At least once a year you must take the crane to a Fassi Service Center for a
check.
(!) Before disconnecting any hydraulic hoses, ensure that there is no pressure
in the hydraulic circuit. After removing hoses always mark them and their
respective ports on the crane. Faulty replacement can cause damage to
the rams and to the hydraulic circuit.
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. 29)
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 hydrau-
lic 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.
