ENGINE BREAK-IN REQUIREMENTS

Note: During the first 20 hours of operation, avoid long periods of no load or sustained maximum load operation. If
the generator is to run for longer than five minutes without a load, shut the generator down.
John Deere engines are supplied with engine break-in oil from the factory. Extra care during the first 100 hours of
engine operation will result in better performance and longer engine life. DO NOT exceed 100 hours of operation
with the break-in oil. Operate the engine at heavy loads (60-90% of maximum) as much as possible. If the engine
has spent significant time at idle, constant speed(s), and/or light load, or if makeup oil is required, a longer break in
period may be needed. Refer to the engine operator's manual for a full description of necessary procedures on the
addition of break-in oil and extension of the break-in period. For more information on regular maintenance intervals,
refer to
Basic Maintenance Schedule - John Deere
