chever comes first. The hydraulic oil change is best done when the

Firstly, the used oil must be drained from the tank; this is done by
the tap (A).
1. Remove the cap from the tap (A) and fit a hose connection + tube
(1/2") to the tap (A).
2. Open the ball-valve on the tap and lead the waste oil, via the
tube, into an appropriate container.
3. Close the ball-valve and fit and tighten the cap to the tap (A)
again when all the waste oil has been drained.
Additionally, new oil is filled into the tank.

oil until the level is between min. and max. on the level glass (C). The
tank contains approx. 45 l. Regarding oil specification - see section
