Horn
Press the optional horn button (refer to Figure 7.29) to
ensure that it sounds to warn personnel in the area.
Figure 7.29 – Upper Control Panel
Electrical Power Outlet
Connect a source of 125 volt AC power to the power-
input connector (refer to Figure 7.30). The connector is
on the left side of the turntable, near the tilt sensor, at
the rear of the machine.
Figure 7.30 – Left Side of Turntable
Some machines may have an electrical outlet cable
already plugged into the outlet on the lower control
panel. In that case, power is supplied by an optional AC
generator. An external power source is not required.
With the engine running, place the optional machine/
generator control (refer to Figure 7.29) 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 generator housing.
Plug an electrical tool into the receptacle at the platform
and at the generator and try to operate the tool to verify
proper operation of the outlet.

4. Turn the master start switch on the front of the upper
control panel to start until the engine starts, then
release it.
5. Let the engine warm to operating temperature.
Danger
Pinch points may exist between moving compo-
nents. Death or serious injury can result from
becoming trapped between components, build-
ings, structures, or other obstacles. Make sure all
personnel stand clear of the aerial platform while
performing the prestart inspection.
6. Test the platform foot switch by moving a boom
function control without stepping on the foot switch.
If movement occurs the interlock is not function-
ing properly. Do not operate the machine until the
problem is corrected.
7. Test the operation of each control in both directions
from the upper controls.
8. The drive range switch and maximum travel speeds
are interlocked through a limit switch on the turn-
table that senses the main boom position. When
the main boom is raised slightly above horizontal
or extended approximately 8′ (2.4 m) 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 out 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.
