CHAPTER 3 MAINTENANCE

3-1 Maintenance schedules

Keeping your generator well maintained will prolong the life of your generator.
Everything needs to be checked including the diesel engine, generator, control cabinet,
and frame. For overhauling procedures, please refer to the instruction manual of the
relative subassembly. If you need these manuals, please call our company and we will
send you one.

Before starting the maintenance, make sure the diesel engine is off.

Please refer to the Table 3-1 for the proper maintenance schedule.
