Test the Engine Idle Select
Operation - Engine Models
Genie specifications require that this procedure be
performed quarterly.
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 individual boom functions. Drive functions
will operate at low idle on most models, but at
reduced performance.
High idle
(rabbit symbol) should be used for
normal machine operation.
