*   If other than Cat Pumps special custom blend, ISO 68 hydraulic oil is used, 

change cycle should be every 300 hours.

**  Each system’s maintenance cycle will be exclusive. If system performance 

decreases, check immediately. If no wear at 1000 hours, check again at 
1500 hours and each 500 hours until wear is observed. Valves typically 
require changing every other seal change.

Duty cycle, temperature, quality of pumped liquid and inlet feed 
conditions all effect the life of pump wear parts and service cycle.

**  Remember to service the regulator at each seal servicing and check all 

system accessories and connections before resuming operation.
