Test the Engine Idle Select
Operation
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
A properly operating engine idle select function is
essential to good engine performance and safe
machine operation. There are two settings.
Low idle (turtle symbol) allows the operator to
control multiple boom and/or drive functions
simultaneously, though at reduced speed. This
setting maintains a consistent low idle.
Foot switch activated high idle (rabbit symbol)
should be used for normal machine operation. This
selection activates high idle only when the foot
switch is pressed down.
1 Turn the key switch to ground controls.
2 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls.
3 Start the engine from the ground controls.
4 Push and release the rpm select button until
high rpm is selected (rabbit symbol).
Result: The engine should change to high
idle.
