11.7. Maintenance after every 400 hours of operation
11.7.1. Replacing the hydraulic oil
It is advised to replaced the hydraulic oil after 400 hours in order to maintain optimal perfor-
mance of the machine's hydraulic functions.
The whole hydraulic system contains 9 L (9.5 qt) oil. The content of the hydraulic oil tank is 8 L
(8.5 qt).
• Before draining the hydraulic oil allow the machine to run for about 5 minutes so that the
hydraulic oil reaches operating temperature. Warm oil is more liquid and will therefore run out
of the system more easily.
• Place a beam of +/-10 cm (+/- 4”) at the back of the track system so that the nose of the ma-
chine tips forward.
