11.5.8 Replacing the hydraulic oil and the oil fi lter
Although the hydraulic system has a closed circuit, oil will be contaminated in due course. This
dirt will be continuously fi ltered away by an hydraulic fi lter. The fouling of this fi lter will reduce
the fl ow of oil and, therefore, cavity may occur. We, therefore, recommend replacing the oil and
the fi lter every 400 working hours.
• Fold away the large safety guard to the left of the machine
to quickly access all involved parts (see § AP.A-P1).
• Find the drain plug at the bottom of the large tank (30L).
(1)
• Place a receptacle that can hold 40 L under the drain
plug and loosen it. (A/F 19)
• After the 30 L oil has drained away from the tank, screw
the plug back and clean up all spilled oil.
• Loosen the hydraulic oil fi lter (2). A specifi c tool can be
used for this. authorised ELIET dealer.
(2)
• Always place a tray under the fi lter (2 L) because when
you unscrew items, oil may fl ow.
• Apply a fi lm of new oil to the seal of the new fi lter.
• Turn the fi lter manually until the seal touches the seat of
the fi lter housing.
• Tension the fi lter by turning it another 1/3 turn.
• Top up the tank by using new hydraulic oil. (capacity: 30 l.)
• Use oil that has a viscosity degree of 46 (see the refer-
ence list in the appendix).
• Clean up any spilled oil. (see § AP.B)
• Carefully close the safety guard upon completion of this
maintenance (see § AP.A-P1).
Note:
Check whether there are any leads during the hours and days after performing these
maintenance tasks. If required, tighten the drain plug a bit extra.
Consider the environment:
Take the oil and fi lter to an authorised collection point that guaran-
tees the expert processing or recycling of oil. Never pour the oil in a sewer drain.
