Check and Adjust the Engine
RPM
Genie specifications require that this procedure be
performed every 500 hours or six months,
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.

can only be adjusted by re-programming the ECM.
If rpm adjustment or service is required, please
contact Genie Product Support.
