Change the oil and oil filter after the first 100 hours, then every 250 hours. If John Deere Plus 50 II engine oil
is used, the interval can be increased to every 500 hours.
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 speeds and/or light load or if makeup oil is required, a longer break-in
period may be needed. Consult the engine operation and maintenance manual for a full description of necessary
procedures on the addition of break-in oil and extension of the break-in period. Use the schedule table above as a
guide for regular maintenance intervals.
EXHAUST FILTER SERVICE REQUIREMENTS
The exhaust filter system contains a diesel particulate filter (DPF). Over time, the DPF will require professional
servicing to remove ash buildup. The expected service interval will be at least 3000 or 4500 hours based on engine
power and operating conditions. Actual service should take place when the indicator light appears on the control
panel LCD. The DPF should be cleaned or replaced by an authorized service provider only. The removal of DPF
ash must be done by removing the DPF from the unit and placing it into specialized equipment.
CAUTION
Do not remove ash by using water or other chemicals. Removing ash by these methods
may cause equipment damage and create unsafe operating conditions.
CAUTION
Only a qualified service provider should remove, handle and dispose of diesel particulate
filters and ash. These materials may be considered hazardous under federal, state and local
regulations, and must be handled and disposed of properly.
To avoid unnecessary buildup of diesel particulates or soot in the exhaust filter system;
1. Utilize the Automatic (AUTO) Exhaust Filter Cleaning mode.
2. Avoid unnecessary idling.
3. Use proper engine oil. Refer to Engine Operator’s Manual.
4. Use only ultra low sulfur diesel fuel. Refer to Engine Operator’s Manual.
