Kohler 3.5CFZ, 4CZ, 5CFZ, 6.5CZ installation manual Scheduled Maintenance

Section 3. Scheduled Maintenance

Use the following service schedule and the hourmeter on the controller to schedule routine maintenance. In addition to the routine services listed in this manual, there are other important steps that should be taken to keep a generator set in top condition. Usually tools and instruments required for these additional steps are not available to the generator set owner. For this reason, the set should be returned periodically to an authorized service dealer/distributor for complete servicing and tune-up. The benefits of such service will be improved performance and continuous satisfactory operation during a long trouble-free service life. Use the Operating Hour Service Log in the back of this manual to document services performed.

Service intervals are located on the top rows of the Service Schedule chart. It indicates how often maintenance tasks need to be done. Each service item is to be repeated at the specified interval. For example, an item required at 50 hours will again need to be performed at 100 hours, 150 hours, etc.

For continued satisfactory operation and longevity of the engine and generator set, proper maintenance and eventual overhaul by a competent mechanic/technician are essential. While it is not possible to anticipate component failure, rough operation, metallic noises, and excessive oil loss are among the indicators of potential problems. Do not ignore these conditions!

NOTE

Operate the generator set with load applied at least once a month. Allow generator set to run about one hour to reach operating temperature. This prevents the formation of corrosion on internal engine components when exposed to the breakdown of exhaust gases and seawater for long periods of generator inactivity. If unit is to be out of service for several months, see Storage Procedure.

WARNING

Accidental starting.

Can cause severe injury or death.

Disconnect battery cables before working on generator set (negative lead first and reconnect it last).

Accidental starting can cause severe injury or

death. Disconnect battery cables (remove negative lead first and reconnect it last) to disable generator set before working on any equipment connected to generator. The generator set can be started by remote start/stop switch unless this precaution is followed.

NOTE

HARDWARE DAMAGE! Engine and generator make use of both American Standard and metric hardware. Be sure to use the correct size tools to prevent rounding of bolt heads and nuts.

NOTE

High-mineral content seawater (salt water) can cause rapid destruction of metals. Wipe up all salt water spillage on and around generator set and keep metal surfaces free from accumulated salt deposits.
