7.10 Annual maintenance
7.10.1 Hydraulic drive (oil change and filter cartridge)
To change the hydraulic oil, the oil reservoir for the hydraulic drive is fitted
with a drain hose, the free end of which is secured to a blind connector by
a jubilee clip.
• Remove the housing cover above the stop bar for the trolley hoist on the
right-hand side and on the outlet side of the machine.
• Undo the jubilee clip (1) and pull the drain hose (2) off the blind
connector. Drain off the oil into a suitable container outside the
machine.
• Then plug the drain hose back onto the blind connector and secure it
with the jubilee clip.
• Fill the tank with fresh oil through the filling opening (1) to rinse the tank
and then drain this oil off again.
• Fill the tank with fresh oil through the filling opening to at least half-way
up the sight glass (2).
