PRESTART CHECKLIST

Before starting the generator, carefully read the prestart checklist. Make sure that all of the items are checked before

trying to start the generator. This checklist applies to both manual and remote starting of the generator.

 Read and understand ALL safety sections at the beginning of this manual.

 Make sure the control power switch is in the “CONTROL OFF/O” position.

 Make sure the circuit breakers are switched “OFF/O”.

 Check that the generator is properly grounded to a good earthen ground per local and NEC

regulations.

 Check all electrical connections at the connection lugs. Are they wired correctly?

 Are the connection lugs tight?

 Check the voltage selector switch and make sure that it is set to the desired voltage.

 Is the voltage selector switch locked?

 Is the generator sitting level?

 Thoroughly check for any water inside, on, or near the generator. Dry the unit before starting.

 Check oil, coolant, and fuel levels and engine battery connections.

 Check the engine fan belt tension and condition.

 Check the engine fan belt guard.

 Check the engine exhaust system for loose or rusted components.

 Check the radiator and surrounding shroud for debris.

 Are any of the generator covers loose or missing?

 Are all preventive maintenance procedures up to date?

 Check that the battery disconnect switch is in the “ON” position, if equipped.

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 operator’s 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.

MANUAL STARTING OF THE GENERATOR

All generators equipped with the Power Zone™ controller will initially start up in “Manual Mode”. This provides the

operator the ability to start the generator as soon as the controller is powered up. Use the following procedure to

start the generator in “Manual Mode”:

1. Move the control power switch to the “CONTROL ON/I” position.
