December 2013 Section 3 • Scheduled Maintenance Procedures
B-12
Test the Platform Self-leveling
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Automatic platform self-leveling throughout
the full cycle of boom raising and lowering is
essential for safe machine operation. The
platform is maintained at level by the platform
leveling slave cylinder which operates in a closed
loop hydraulic circuit with the master cylinder
located at the base of the boom.
A platform self-leveling failure creates an unsafe
working condition for platform and ground
personnel.
1 Start the engine from the ground controls and
lower the boom into the stowed position.
2 Hold the function enable/rpm select toggle
switch to either side and adjust the platform to a
level position using the platform level toggle
switch.
3 Raise and lower the primary boom through
a full cycle.
Result: The platform should remain level at
all times to within ±5 degrees.
B-13
Test the Engine Idle Select
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
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).
Result: The engine should not change to
high idle.
6 Press down the foot switch.
Result: The engine should change to high idle.
7 Move the engine idle control switch to foot
switch activated low idle (turtle symbol).
Result: The engine should change to low idle.
