Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of 10°F
(0°C) or below.
Preparing for Operation
Use the following procedure to prepare the aerial platform
for operation.
1. Perform a prestart inspection as described in Chap-
ter 7.
2. Place the battery disconnect switch in the on posi-
tion.
3. Close and latch the doors.
4. Before painting or sandblasting make sure the sand-
blast protection kit and the platform control cover are
properly installed. These options, when used prop-
erly will protect the control placards and cylinder rods
from paint overspray and abrasion while sandblast-
ing.
Lower Controls
The lower controls override the upper controls. This means
that the lower controls can always be used to operate
the platform regardless of the position of the upper con-
trol emergency stop button.
Boom, turntable, and platform functions may be oper-
ated from the lower controls. The lower controls may be
used for initial set up of the aerial platform, and for testing
and inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls. Refer to
Figure 8.2.
1. On dual fuel machines, set the fuel switch to either
LPG or gasoline.
2. Open the shut-off valve on the tank if using LPG.
3. Pull the emergency stop button (refer to Figure 8.2)
outward and place the control selector switch in the
ground position.
4. Turn the start switch to on and pause a few seconds
while the alarm sounds to alert others that the ma-
chine is about to start. Turn the switch to start, then
release it to on. The engine will not start if the switch
is left in the on position for 30 seconds or longer
before turning it to start. The switch must be turned
back to off before the engine will start.
5. Let the engine warm to operating temperature.
6. Hold the ground operation switch up while operating
the control toggle switches.
Figure 8.2 – Lower Controls

rection.

The upper controls may be used for driving the aerial plat-
form and positioning the booms and platform while on the
job.
Use the following procedure to operate machine func-
tions using the upper controls.
1. At the lower controls, pull the emergency stop but-
ton outward and turn the start switch to on. Place
the control selector switch in the platform position.
2. On dual fuel machines, set the fuel switch to either
LPG or gasoline.
