Note - Oil level check and oil change (gearboxes) and lubricating the machine
Effect: Long expected service life of machine
• First oil change on all gearboxes after 50 operating hours, then every 200 operating hours
(but at least once a year).
• Before using the machine always check the oil level.
• With bio-degradable oils the changing intervals must be complied with absolutely because
of ageing of the oils.
