HYDRAULIC SYSTEM, OIL CHANGE, CHANGING THE FILTER INSERT
DANGER
• Frequent skin contact with used hydraulic oil may cause
skin damages and other injuries! Wear rubber gloves for
changing the oil. Wash any hydraulic oil carefully from your
skin.
• The hydraulic tank is put under pressure! Danger of being
burnt by hot transmission oil! Wear rubber gloves and hold
the oil trough under the discharge hole in such a way that
you cannot come into contact with the extruding oil. Loosen
the screw plug (3) by a few turns to let the pressure escape,
before opening the cap (F).
Have a collecting container of sufficient capacity ready when carrying
out this work.
1. Park and secure the machine as described in chapter "Preparing
the Machine for Maintenance".
2. Remove screws (1) and open the cover (2) to he front via the
hydraulic tank.
3. Unscrew the venting filter (3) slowly so that the pressure can
escape.
4. Then unscrew the cap (F) of the oil filler inlet.
5. Place the collecting container below the drain valve.
6. Remove the drain plug (8) of the drain valve. Screw the drain pipe
(9) (included with tools) into the threaded hole of the drain plug
(8). This opens the drain valve. A hose can be connected to the
drain pipe in order to be able to collect the oil better.
7. After the oil has drained, unscrew the drain pipe and re-seal the
drain valve with the drain plug and an undamaged washer.
