Changing the hydraulic drive oil - technical personnel only
The oil filter must be replaced after the first 25 hours of operating and after that every 100
hours of operation. The service should be carried by an authorised
workshop.
•
The oil change should be carried out in conjunction with an oil filter change (refer to the
appendix – spare parts list for spare part no.).
•
Allow the drive to run for a short while before changing the oil, so that the oil can drain out
more easily.
