Test the Engine Idle Select

A properly operating engine idle select switch
is essential to good engine performance and safe
machine operation. There are two settings.
Foot switch activated low idle (turtle symbol)
allows the operator to control individual boom
functions.
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 Pull out the red Emergency Stop button to the
on position at both the ground and platform
controls.
2 Start the engine from the ground controls then
move and hold the function enable/rpm select
toggle switch to the high idle (rabbit symbol).
Result: The engine should change to high idle.
3 Release the function enable/rpm select toggle
switch.
Result: The engine should return to low idle.
4 Turn the key switch to platform controls.
5 Move the engine idle control switch to foot
switch activated high idle (rabbit and foot switch
symbol).

Test the Fuel Select Operation -
Ford Models
The ability to select and switch between
gasoline and LPG fuels as needed is essential to
safe machine operation. A fuel selection can be
made when the engine is running or not.
Switching malfunctions and/or the failure of the
engine to start and run properly in both fuel
modes and through all idle speeds can indicate fuel
system problems that could develop into a
hazardous situation.
1 Move the fuel select switch to gasoline and then
move the engine idle control switch to foot
switch activated high idle (rabbit and foot switch
symbol).
2 Start the engine from the platform controls and
allow it to run at low idle.
3 Press down the foot switch to allow the engine
to run at high idle.
Result: The engine should start promptly and
operate smoothly in low and high idle.
