Operation

Preparing for Operation

Use the following procedure to prepare the aerial platform
for operation.
1. Perform a prestart inspection as described in the "Daily
Preventative Maintenance Checklist" on page 23.
2. Place the battery disconnect switch in the on position.
3. Close and latch the cowling doors.

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. 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 (ref: Figure
3 on page 8).
1. Place the emergency stop switch in the on position.
Insert the key into the controls switch and turn the
switch to the lower control position.
2. Operate the preheat button if required.
• When the engine is warmed up or the ambient tem-
perature is above 10°C (50°F), it is not necessary to
operate the glow plugs before starting the engine.
• When the ambient temperature range is 10°C
(50°F) to -5°C (23°F), press and hold the preheat
button for five seconds before starting the engine.
• When the ambient temperature is below -5°C
(23°F), press and hold the preheat button for ten
seconds before starting the engine.
3. 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.
4. Let the engine warm to operating temperature.
5. Hold the ground operation switch in the on position
while operating the boom and turntable control toggle
switches.
6. Release the function toggle switch to stop movement.
7. Place the ground operation switch in the off position
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 functions
using the upper controls (ref: Figure 4 on page 8).
1. At the lower controls, place the emergency stop
switch in the on position and place the controls switch
in the upper controls position.
2. Enter the platform and securely close the gate.
3. Attach the fall restraint lanyard to one of the anchor
points.
4. Pull the emergency stop outward.
5. Turn the start switch to the on position and pause a
few seconds while the alarm sounds to alert others
that the machine is about to start. Operate the preheat
switch if required.
• When the engine is warmed up or the ambient
temperature is above 10°C (50°F), it is not neces-
sary to operate the glow plugs before starting the
engine.
• When the ambient temperature range is 10°C
(50°F) to -5°C (23°F), press and hold the preheat
button for five seconds before starting the engine.
• When the ambient temperature is below -5°C
(23°F), press and hold the preheat button for ten
seconds before starting the engine.
6. Turn the switch to start, then release it to on. The en-
gine 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.
7. Let the engine warm to operating temperature.

Boom Operation

boom, or platform functions.
1. Step down on the platform foot switch. This switch
must be held down to operate the upper controls.
2. Hold the appropriate control in the desired direction.
Always look in the direction of movement.
3. To stop movement release the control to its neutral
