HECKING HYDRAULIC OIL LEVEL
The control must be carried out with the platform (EWP) and the outriggers in the rest posi‑
tion on flat land. Check the oil level from indicator A; the oil must be half way on the level indi‑
cator.
If this is not the case, top‑up the oil through cap B.
7.13.1 H
YDRAULIC OIL
For top‑up or replacement of hydraulic oil ONLY use JLG oil.
7.14 C HECKING LEAKAGE FROM THE HYDRAULIC SYSTEM
Visually check all flexible pipes, connections and all other components in the hydraulic
system, to identify any possible leaks.
Leaks can normally be eliminated by tightening the connections correctly. Leaks from
gaskets (o‑ring, sealing rings, etc.), cannot be eliminated by just tightening as the gasket leaks
because it is damaged or hardened.
Sealing can only be restored by replacing the gasket.
