MAINTENANCE 

C.1 

WARRANTY TERMS 

The manufacturer declines all responsibility for damage to the crane caused by failed maintenance 

or lubrication.  Preventive routine maintenance refers to machine use in non-abrasive and  non-

corrosive environments.  Failure to abide by this stipulation shall result in all guarantees for faults 

being declared null and void. 

 

  All repairs, modifications and maintenance (excluding routine) must be performed by an 

authorised assistance centre. All repair reports drafted by authorised assistance centres following 

routine and extraordinary maintenance must be recorded and archived by the owner of the crane. 

 

 

C.2 

ORDINARY MAINTENANCE 

The following routine maintenance shall be performed by the operator to ensure machine efficiency: 

-  greasing 

-  filling up the oil tank 

-  crane cleaning 

-  wire rope inspection (if present) 

 

Check the following before performing any maintenance operation: 

-  The vehicle must be switched OFF and the brake applied 

-  The power supply to the crane must be switched OFF 

 

 

C.2.1 

GREASING 

Grease the machine at regular intervals to improve crane functioning and avoid unnecessary 

extraordinary maintenance. Greasing occurs in two different ways: 

-  manual 

-  under pressure 

 

MANUAL GREASING 

Remove grease from telescopic extensions using a soft spatula (plastic or wood). Use a brush to 

spread a new layer of grease on the contact surface. 

Use a type of grease compatible with that indicated in the following table. 

 

Recommended grease (NLGI 0 - DIN 51818) 

TOTAL 

 

 

 

 

CERAN CA 

 

 

 

 

 

PRESSURE GREASING 

Carefully clean the grease nipple. Insert new grease until the grease is coming out of the joints to 

ensure that all the old grease is replaced by new grease. Carefully remove any excess grease. 

Use a type of grease compatible with that indicated in the following table. 

 

Recommended greases (NLGI 2 - DIN 51818)
