a.
Piston ring life varies greatly, depending on application, gas, and operating pressures. Consult factory for additional
recommendations for your specific applications and operating pressures. The initial set of piston rings may wear
faster than replacement rings. Piston ring life tends to get better as the ring material transfers into the cylinder wall
surfaces. On units with coated cylinders it is recommended to replace the initial piston rings after 1,000 hours.
b.
Change oil and filter every 250 hours of operation or every 45 days, whichever occurs first.
c.
Holddown screws must be checked at least once in the first 200 hours of operation.
d.
Includes rings, valves, packing and gaskets.
e.
All bearings, crossheads, rings, valves, packing and gaskets.
*
Recommended maintenance as suggested above are general guidelines only. Your specific maintenance
requirements may vary depending on the operating conditions and duty cycle.
