Section 3 - Maintenance Routine Maintenance Service Schedules Service Intervals for Attachments 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. 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. 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. Table 1.
Service Intervals for Hydraulic Oil and Filters according to Frequency of Breaker, Crusher or Pulverizer Use (1) The filters must be changed whenever the period of breaker/crusher/pulverizer use exceeds 100hrs, regardless of the total number of hours the machine has worked { Check oil level and top up as required z Change …
