Check and Adjust the
Engine RPM
Genie requires 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.
Deutz models:
1 Start the engine from the
ground controls.
2 Push one of the LCD screen buttons shown until
engine rpm is displayed.
Result: Low idle should be 1500 rpm.
Skip to step 5 if the low idle rpm is correct.
3 Loosen the locknut on the low idle adjustment
screw.
