*: The power rating of the engine indicated in this document is the net power output tested on a production engine for the engine
model and measured in accordance with SAE J1349 at 3,600 rpm (net power) and at 2,500 rpm (max net torque). Mass
production engines may vary from this value. Actual power output for the engine installed in the final machine will vary depending
on numerous factors, including the operating speed of the engine in application, environmental conditions, maintenance, and
other variables.
