Maintenance
Important!
Before picking up an attachment, the operator must make sure it can be hitched

Perform maintenance on the quickhitch system once a day with the other mainte-
nance work for the machine.
Perform visual checks for possible defects, damage or cracks.
Remove all dirt on and around moving parts.
The claws must be clean and slightly greased.
Apply grease to the pins via grease nipples S.
Apply grease to the friction surfaces of the lock mechanism via 2 further grease nipples N
on either side of the quickhitch (see Fig. 80).
Before starting work, check the acoustic signal which must be audible when pressing
