Figure 8.1 – Lower Controls
Axle Controls
To raise the boom above horizontal and to extend the
boom fully, while operating from either the lower or upper
controls, the rear axles must be extended and properly
locked into position.
The machine can be driven from the upper controls with
the axles extended or retracted. The boom must be low-
ered and retracted before beginning this procedure.
3. Place the warm-up switch in the on position.
4. After the hydraulic fluid reaches 10°C (50°F) as
indicated on the thermometer, place the warm-up
switch in the off position.
Manually Warming The Hydraulic System
The hydraulic oil may be warmed by placing the boom/
axle switch in the axle position. The boom must be in
the stowed position.
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
-13°C (10°F) 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
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 operated
from the lower controls. Boom elevation and extension
is limited when the rear axles are retracted. The lower
controls may be used for initial set up of the aerial plat-
form, and for testing 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.
