Test the Engine Idle Select
Operation
Genie requires 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 three 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.
High idle (rabbit symbol) allows the operator
to control multiple boom and/or drive functions
simultaneously. This setting maintains a
consistent high idle.
Foot switch activated high idle (rabbit and foot
switch symbols) 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.
5 Push and release the rpm select button until low
rpm is selected (turtle symbol).
Result: The engine should return to low idle.
