Retracting the Outriggers With an Outrigger/Boom
Interlock System:
The booms must be stowed before
the interlock system will allow the outriggers to be
retracted. Stow the booms as described in this
section, “Storing the Aerial Lift”. Select “ground
controls” with the control selector. Then raise the
outriggers as described previously.
HYDRAULIC TOOL OPERATION AT THE GROUND
(Optional)
- Select ground controls at the lift/ground
control selector then connect the hydraulic tool hoses
to the tool power outlets (quick-disconnect couplings).
Activate the tool-power valve by pulling the tool power
valve knob “out”. The other aerial lift controls will not
respond while the hydraulic tools are being operated.
To disconnect the hydraulic tools, the tool-power valve
must be turned “off” so that the pressure in the system
is relieved. This is done by pushing the tool-power
valve knob “in”. Then the tool hoses can be
disconnected safely and easily from the tool power
outlets (quick-disconnect couplings). The tool-power
controls are shown in Figure 4.3.
WARNING
: FAILURE TO RELIEVE
PRESSURE TO THE TOOL PORTS BEFORE
CONNECTING OR DISCONNECTING THE
HYDRAULIC TOOL HOSES MAY RESULT IN A
HIGH PRESSURE HYDRAULIC OIL SPRAY. THIS
SPRAY OR MIST CAN PUNCTURE OR BECOME
EMBEDDED BENEATH THE SKIN OR
CONTAMINATE THE EYES. THESE CONDITIONS
REQUIRE IMMEDIATE MEDICAL ATTENTION.

LOWER CONTROL OPERATION
The Lower Controls are located on the turret as shown
Figure 4.4.
CONTROL SELECTOR LEVER - The 3-position
control selector is used to select operation of the aerial
lift from the upper or lower controls. Also this control
serves as the emergency stop for the upper controls.
When a control station is selected the other is one
inoperable.
BOOM CONTROL LEVERS - The remaining control
levers at the lower control station are spring-loaded.
The lower control decal identifies the function of each
control lever and indicates which direction to move
the control lever for the desired movement. When
released the control lever will return to the centered or
neutral position and motion ceases. A locking handle
is installed over the platform leveling control lever to
lock the lever in the neutral position and prevent
inadvertent actuation. For actuation, the control
handle must be pulled out.
PLATFORM LEVELING CONTROL - This control
activates the hydraulic platform leveling to level the
platform.

ELECTRIC SELECTOR STATION - The electric
controls at the pedestal are arranged as shown in
Figure 4.5 A description of each control and the
method of operation is given on following page.
