7.12 C
HECKING THE HYDRAULIC OIL LEVEL
The check must be carried out with the platform (EWP) and the stabilisers in the resting
position on flat ground.
Check the oil level on indicator A; the oil must be half way up the level indicator.
If this is not the case, top up through cap B.
7.12.1 H
YDRAULIC OIL
To top up or replace the hydraulic oil ONLY use JLG oil.
7.13 C HECKING FOR LEAKS IN THE HYDRAULIC SYSTEM
Visually check all hoses, connections and all other components in the hydraulic system, in
order to identify any possible leaks.
Leaks from hoses can normally be resolved by tightening the fittings.
Leaks from gaskets (O rings, sealing rings etc.) cannot be eliminated by simply tightening, as
gaskets usually leak because they are damaged or have become hard.
The correct tightness can only be restored by replacing the gasket.
