Check and Adjust the Engine
RPM
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.
Note: Two people will be required to perform this
procedure.
Note: Perform this procedure with the engine at
normal operating temperature.
1 Connect an rpm gauge to the engine, and then
start the engine from the ground controls.
Result: Low idle should be 2000 rpm.
Skip to step 3 if the low idle rpm is correct.

2 Loosen the lock nut, then turn the low idle
