Manually Warming The Hydraulic System
The hydraulic oil may be warmed by bottoming out the
boom extension cylinder. Raise the main boom so it is
horizontal and operate the boom retract function while
the machine is stowed. With the cylinder bottomed out
the oil flow will produce heat to warm the hydraulic oil.
A
Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating charac-
teristics and can increase component wear. Only use
hydraulic fluid as recommended.
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 plat-
form 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
properly will protect the control placards and cylin-
der rods from paint overspray and abrasion while
sandblasting.
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 control 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 test-
ing and inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls.
1. Pull the emergency stop button (refer to Figure 8.1)
outward. Insert the key in the control selector and
turn the switch to the lower control position.
Figure 8.1 – Lower Controls
2. Press the start button until the engine starts, then
release. The engine will not start if the control se-
lector switch is left in the lower control position for
30 seconds or longer before starting the engine. The
control selector switch must be turned back to off
before the engine will start.
3. Let the engine warm to operating temperature.
4. Hold the ground operation switch up while operat-
ing the control toggle switches.
5. Hold the appropriate toggle switch in the desired
direction.
6. Release the function toggle switch to stop move-
ment.
7. Place the ground operation switch in the off posi-
tion when no functions are being operated.
Upper Controls
The upper controls may be used for driving the aerial
platform 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. Insert the key in the control selector
and turn the switch to the upper control position.
