Maintenance
A specific maintenance schedule shall be adopted for the machine if any hydraulic attachment is used over a signifi-
cant period of time. In particular, the maintenance of the hydraulic system shall be more frequent because the usage
of hydraulic attachments severely affects the properties of the hydraulic fluid.
The following table prescribes the required intervals for the maintenance operations to be performed on the hydraulic
system of the machine depending upon the percentage of the usage of the attachment.
Hydraulic oil level check
Hydraulic oil suction filter cleaning
Hydraulic oil return filter replacement
Pilot filter replacement
Hydraulic oil analysis
Hydraulic oil and filters replacement
Moreover, the following operations shall be performed every 10 h if any attachment other than a bucket is used:
• lubricate the bucket pins and the whole bucket linkage.
• check the tightening torques, in particular if the machine is used in demolition applications.
• check the frames and the structures for damages or cracks, in particular if the machine is used in demolition appli-
cations.
• if the hydraulic attachment is used, check the hydraulic lines and connections towards the attachment.
