Check and Adjust the
Engine RPM - Ford and Deutz
Models
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Maintaining the engine rpm at the proper setting for
both low and high idle is essential to good engine
performance and service life. The machine will not
operate properly if the rpm is incorrect and
continued use may cause component damage.
Ford models:
Note: The engine rpm is controlled by the ECM and
can only be adjusted by re-programming the ECM.
If rpm adjustment or service is required, please
contact Genie Service Department OR your local
Ford dealer.
Deutz models:
Note: This procedure will require two people.
