A Caution
Not all hydraulic fluid is suitable to use in the hy-
draulic system. Some have poor lubricating char-
acteristics 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
-2°C (0°F) or below.
Preparing for Operation
Use the following procedure to prepare the aerial plat-
form for operation.
. 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
sandblast protection kit and the platform control
cover are properly installed. These options, when
used properly will protect the control placards and
cylinder 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
testing and inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls. Refer to
Figure 8.2.
. Pull the emergency stop button (refer to Figure 8.2)
outward. Insert the key in the control selector and
turn the switch to the lower control position.
2. Press the start button until the engine starts, then
release. The engine will not start if the control selec-
tor 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 operating
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 position
when no functions are being operated.
