Check and Adjust the
Engine RPM
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.
Gasoline/LPG Models:
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 the Genie
Industries Service Department OR
your local Ford dealer.
