Check and Adjust the
Engine RPM - Ford and Deutz
Models
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:
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 Industries
Service Department OR your local
Ford dealer.
Deutz models:
This procedure will require two
people.
1 Remove the two engine pivot plate retaining
bolts. Swing the engine pivot plate out away
from the machine and secure it from moving.
Crushing hazard. Failure to secure
the engine pivot plate from moving
could result in death or serious
injury.

2 Connect an rpm gauge to the engine, and then
start the engine from the ground controls.
Result: Low idle should be 1500 rpm.
Skip to step 4 if the low idle rpm is correct.
3 Loosen the low idle lock nut, then turn the low
idle adjustment screw clockwise to increase the
rpm or counterclockwise to decrease the rpm.
Tighten the low idle lock nut and recheck the
rpm.
