8.16 Hydraulic oil
CAREFUL! Never top up the oil in the oil tank if not all the cylinders have been retracted.
Changes in its level might otherwise cause the tank to flow over!
The type of hydraulic oil used is HDZ hydraulic oil. It is important that there is always sufficient
hydraulic oil in the tank. To see how much hydraulic oil is in the tank, lift the return filter. The
following steps must be taken to top up the tank:

Make sure that all cylinders are retracted.

Unscrew the cap of the return filter.

Remove the hydraulic oil return filter, ensuring that there is a clean drip tray and working
environment to prevent contamination in the hydraulic tank and in the filtration system.

Check the hydraulic oil level using a flashlight by looking in the hydraulic tank. The maximum
level is up to the edge of the filling neck.

Reinstall the hydraulic oil return filter and clean it.

Start the machine and operate the hydraulic function several times without load; if oil comes
out of the vent, this indicates that there is too much hydraulic oil in the system.
If there is excess, wrong or out-of-date hydraulic oil in the tank, it can be drained by loosening a hose
coupling on the underside of the tank. Collect this hydraulic oil. Flush the tank briefly with new
hydraulic oil to flush out the old hydraulic oil and any dirt. Re-tighten the hose coupling and fill the
tank with new HDZ hydraulic oil. Changing the hydraulic oil requires 55 litres of fresh oil.
