damage or deformation. Visually check the rail and
toeboard welds for cracks. All bolts and nuts fastening
the platform in place must be present and not show any
signs of looseness.
Inspect the gravity gate to be sure it is present, is not
damaged, and moves freely.
Inspect the swinging gate to see that it swings freely,
closes firmly, and is not deformed in any way. Make sure
the spring closes and secures the gate when closed.
Lanyard Anchors
There are two lanyard anchors below the upper control
panel (refer to Figure 7.18).
Visually inspect the lanyard anchors to make sure they
are in place, are not deformed and are securely fastened
to the platform.
Operating Controls
Use the following procedure to operate the machine from
the upper controls.
1. Turn the battery disconnect switch on.
2. At the lower controls, place the emergency stop
switch and the master switch in the on position. Place
the controls switch in the platform position.
3. At the upper controls (refer to Figure 7.19), pull the
emergency stop button outward.
Figure 7.19 – Upper Controls
4. Turn the master start switch on the front of the up-
per control panel to start until the engine starts, then
release it.
Note
If the machine has a GM engine, there will be a 7 to 10
second delay after starting the engine, before the throttle
will go to mid or high. Start the engine and wait 10 seconds
before proceeding with machine operation.
5. Let the engine warm to operating temperature.
A
Danger
Pinch points may exist between moving components.
Death or serious injury can result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure all personnel stand
clear of the aerial platform while performing the pre-
start inspection.
A
Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunc-
tioning. Death or serious injury can result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
6. Place the drive/boom selector in the boom position.
7. Test the platform foot switch by moving a boom
function control without stepping on the foot switch.
If movement occurs the interlock is not functioning
properly. Do not operate the machine until the prob-
lem is corrected.
8. Test the operation of each control in both directions
from the upper controls.
9. Place the drive/boom selector in the drive position.
The drive range switch and maximum travel speeds
are interlocked through a limit switch on the turntable
that senses the main boom position. When the main
boom is raised approximately 2.4 m (8
′) the machine
should travel in low speed only. To operate in high
speed the booms must be stowed.
Emergency Stop
Push the emergency stop button in to turn off the engine.
The upper control functions should not operate with the
emergency stop in this position.
Emergency Power
Pull the emergency stop button up and place the anti-
restart master switch in the on position.
Hold the engine/emergency power switch in the emer-
gency power position and step on the platform foot switch
to operate the aerial platform from the upper controls
using the emergency power system.
Horn
Press the horn button (refer to Figure 7.19) to ensure that
it sounds to warn personnel in the area.
Electrical Power Outlet
With the engine running, place the machine/generator
control (refer to Figure 7.20) in the generator position to
provide electrical power to the two electrical outlets at
the platform and to the outlet on the end of the genera-
tor housing.
