Note
We recommend to use the BOMAG filling and fil-
tering unit with fine filter to fill the system. This en-
sures finest filtration of the hydraulic oil, prolongs
the lifetime of the hydraulic oil filter and protects
the hydraulic system.

Fill in new hydraulic oil.
l
Insert a new filter and reassemble the filter
cover.
l
Replace the breather filter (2).
l
Perform a test run and check the system for
leaks.
