Note (1)
Net power advertised is the power available at the flywheel when the engine is equipped with fan, air cleaner, muffler and alternator.
The operator sound pressure level was measured according to the test procedures and conditions specified in ISO 6396:2008. The measurement was conducted at the maximum engine cooling fan speed.
Note (2)
Net torque rise meets SAE J139.
Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors or windows are open for extended periods or in a noisy environment.
Note (3)
No engine derating required up to 3050 m (10,000 ft) altitude.
The machine sound power level was measured according to the test procedures and conditions specified in ISO 6395:2008. The measurement was conducted at the maximum engine cooling fan speed.
