! If the work environment is dusty,
increase the number of times that
perform this step.
It is necessary to replace the hydraulic
filter to maintain good machine
performance and service life. Dirty or
blocked filters may cause a decrease
in machine performance and
continuous use may result in damage
to components. An increase in the
number of replacement filters is
required for the extremely dirty
working condition.
