Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunction-
ing. Death or serious injury could result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
5. Test the interlock switch by moving the joystick with-
out engaging the interlock switch.
If movement occurs, the interlock is not functioning
properly. Do not operate the machine until the prob-
lem is corrected.
6. Place the drive/lift selector switch in the drive position
and test the operation of the joystick in both direc-
tions. The lift functions should not operate with the
selector in the drive position.
Squeeze and hold the interlock switch against the
joystick. Test the steer switch in both directions using
the steering switch.
5. Visually check the platform welds for cracks.
6. While facing the front of the platform, firmly grasp each
of the latch handles and squeeze firmly to unlock the
extension deck. Pull backward to retract the extension
deck to the stowed position. Release the handles to
lock the platform in position (refer to Figure 8.17).
7. Make sure the platform extension deck is locked in
position.
Operating Controls
Warning
The potential for an accident increases from improp-
erly driving or steering the aerial platform. Death
or serious injury could result from such accidents.
Make sure the upper control panel is securely fas-
tened inside the platform and facing the front of the
machine.
Avoid driving the platform with the upper controls facing
the rear or side of the machine. In this position the ma-
chine is difficult to control because the drive and steer
control movements and their resulting machine move-
ments will not correspond.
Only operate the upper controls when the upper control
panel is securely fastened inside the platform and facing
the front of the machine.
Use the following procedure to operate and test the ma-
chine from the upper controls:
1. Make sure the battery disconnect is turned on.
2. At the lower controls, pull the emergency stop button
outward.
3. Turn the control select/ground operation switch to the
upper control position.
4. At the upper controls (refer to Figure 8.18), pull the
emergency stop button outward.
