BHydraulic Oil Check with
Hydraulic Breakers
The hydraulic oil change after 1000 operating
hours in the operator's manual is based on the
type of work done. The following inspection
measures are valid when hydraulic breakers are
used:
1. Changing and filling up of hydraulic oil
(1) The hydraulic oil must be changed more
often when breakers are used because
the machine is subject to harder
conditions than at normal excavating
work.
(2) Use only the recommended oils
mentioned in the operator's manual
when changing or topping up oil.
(3) When filling up oil, do not mix oils of
different makes.
2. Changing the return filter and oil
(1) The filter must be changed more often
because of contamination resulting
from the frequent assembly and
disassembly of the hoses.
(2) Use the correct replacement filter.
(3) Oil change according to operating
hours.
