Caution
The hydraulic oil must also be changed after ma-

Perform the oil change when the hydraulic oil is
warm.
Replace the hydraulic oil filter elements with every
hydraulic oil change.
Change the filter only after the hydraulic oil
change and after the test run.
Clean the area round hydraulic oil tank, filler
opening and breather filter.
Do not start the engine after draining the hydraulic
oil.
Do not use any detergents to clean the system.
For quality and quantity of oil refer to the "table of
fuels and lubricants".
When changing from mineral oil based hydraulic
oil to an ester based biologically degradable oil,
you should consult the lubrication oil service of
the oil manufacturer for details.

We recommend to use the BOMAG filling and filtering
unit with fine filter to fill the system. This ensures finest
filtration of the hydraulic oil, prolongs the lifetime of the
hydraulic oil filter and protects the hydraulic system.
