TABLE B PROCEDURES
B-8
Test the Ground Control Override
A properly functioning ground control override is
essential to safe machine operation. The ground
control override function is intended to allow
ground personnel to operate the machine from the
ground controls whether or not the Emergency
Stop button on the platform controls is in the
ON
or
OFF
position. This function is particularly useful if
the operator at the platform controls cannot return
the boom to the stowed position.
1 Push in the platform Emergency Stop button
to the
OFF
position.
2 Turn the key switch to ground control and lift
the red Emergency Stop switch cover and
move the toggle switch to the
ON
position.
3 Activate the function enable switch and operate
each boom function through a partial cycle at
the ground controls.
Result: All boom functions should operate.
B-9
Test the Platform Self-leveling
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 is controlled by the
master cylinder located at the base of the primary
boom. A platform self-leveling failure creates an
unsafe working condition.
1 Turn the key switch to ground control and lift up
the Emergency Stop Switch cover at the
ground controls and move the toggle switch to
the
ON
position. Pull out the Emergency Stop
Button to the
ON
position at the platform
controls.
2 Activate the function enable switch and lower
the boom to the stowed position.
3 Activate the function enable switch and adjust
the platform to a level position using the
platform leveling switch.
4 Activate the function enable switch and raise
and lower the primary boom through a full
cycle.
Result: The platform should remain level at
all times to within ±5 degrees.
B-10
Test the Service Horn
A functional service horn is essential to safe
machine operation. The service horn is activated
at the platform controls and sounds at the ground
as a warning to ground personnel. An improperly
functioning horn will prevent the operator from
alerting ground personnel of hazards or unsafe
conditions.
1 Turn the key switch to platform control and lift
the red Emergency Stop switch cover and
move the toggle switch to the
ON
position at the
ground controls. Pull out the Emergency Stop
Button to the
ON
position at the platform
controls.
2 Push down the service horn button at the
platform controls.
Result: The service horn should sound.
