Service Intervals for Attachments
When using a breaker, crusher or pulveriser,
contamination and degradation of the hydraulic oil occurs
much more quickly than in normal excavating use. If the
machine is used with increasingly degrading oil it can
cause problems in the control valve, premature wear of the
hydraulic pump and damage to the hydraulic system as a
whole.
Servicing of the hydraulic oil and filters must be done more
frequently according to the percentage of total operating
hours involving use of the breaker, crusher or pulverizer.
When a breaker, crusher or pulverizer is fitted, ensure that
the oil and filters are changed at the intervals shown in the
table below.
The hydraulic oil must be sampled and checked for
contamination and degradation at the intervals shown.
Consult your JCB Distributor who will have the facilities to
do this work and ensure that the hydraulic system is
properly maintained.
