You can help maintain system performance andcatch problems early by:• Following the inspection and maintenance schedule shown on this page• Enrolling hydraulics-intensive machines in our Custom Hydraulic Service Program• Paying attention to the repair indicators listed on page 15Custom Hydraulic Service (CHS)Once a year or every 2,000 hours, we recommend having your hydraulic systemsinspected by our trained service professionals. During these CHS inspections we:• Conduct a detailed visual walkaround inspection of the hydraulics, enginecompartment, cab, power train and ground engaging tools• Drift test all hydraulic cylinders• Perform complete checks of cycle times and system pressures• Stall test the hydraulic system• Take a sample of the hydraulic oil and perform S·O·S ServicesAfter interpreting the inspection and fluid analysis results, we’ll meet with you todeliver a complete report. If service is necessary, we’ll also provide a quote. Weoffer a variety of repair options and can help you decide on the one best for you.
