Test drive and brake
30.Press the drive function button.
31.Slowly move the control handle in the di-
rection indicated by the up arrow on the
control panel until the machine begins to
move, then return the control handle to the
center position.
⊙ Result: The machine should move in the
direction that the arrow points on the con-
trol panel, then come to an abrupt stop
when the control handle is returned to the
center position.
32.Press and hold the function enable switch
on the control handle.
33.Slowly move the control handle in the di-
rection indicated by the down arrow on the
control panel until the machine begins to
move, then return the control handle to the
center position.
⊙ Result: The machine should move in the
direction that the down arrow points on the
control panel, then come to an abrupt stop
when the control handle is returned to the
center position.
Note: The brakes must be able to hold the
machine on any slope it is able to climb.
Test elevated drive speed
34.Press the lift function. Press and hold the
function enable switch on the control han-
dle. Raise the platform approximately 2.1
m from the ground.
35.Press the drive function button.
36.Press and hold the function enable switch
on the control handle. Slowly move the
control handle to full drive position.
⊙ Result: The maximum achievable drive
speed with the platform raised should not
exceed 20 cm/s.
If the drive speed with the platform raised
exceeds 20 cm/s, immediately tag and re-
move the machine from service.
Test the tilt sensor operation
Note: Perform this test from the ground with
the platform controller. Do not stand in
the platform.
37.Fully lower the platform.
38.Place a 2x4 or similar piece of wood under
both wheels on one side and drive the ma-
chine up onto them.
39.Raise the platform approximately 2.1 m
from the ground.
⊙ Result: The platform should stop. The tilt
alarm should sound 180 times each mi-
nute.
40.Move the control handle in the direction in-
dicated by the up arrow, then move it by
the down arrow.
⊙ Result: The drive function should not work
in either direction.
41.Lower the platform and remove both
pieces of wood.
Test the pothole guards
Note: The pothole guards should automati-
cally deploy when the platform is
raised. The pothole guards activate
limit switches that allow the machine to
continue to function. If the pothole
guards do not deploy, an alarm sounds
and the machine will not drive or steer.
42.Raise the platform.
⊙ Result: When the platform is raised 2.1 m
from the ground, the pothole guards
should deploy.
43.Press on the pothole guards on one side,
and then the other.
⊙ Result: The pothole guards should not
move.
44.Lower the platform
⊙ Result: The pothole guards should return
to the stowed position.
45.Place a 2x4 or similar piece of wood under
a pothole guard.
⊙ Result: Before the platform is raised 2.1 m
from the ground, the alarm should sound,
the drive should not operate.
46.Lower the platform and remove the 2x4 or
similar piece of wood.
