Operation
10 AB60JRT
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of -12°C
(10°F) or below.
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
17.
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 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. 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 6).
1. Pull the emergency stop button 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. Turn the boom speed knob to slow.
5. Hold the ground operation switch up while operating
the control toggle switches.
6. Hold the appropriate toggle switch in the desired
direction.
7. Release the function toggle switch to stop move-
ment.
8. 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.
1. At the lower controls, pull the emergency stop button
outward. Insert the key in the control selector and turn
the switch to the upper control 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 anti-restart master switch to on and pause
a few seconds while the alarm sounds to alert others
that the machine is about to start. Turn the switch to
start, then release it to on. The engine 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.
6. Let the engine warm to operating temperature.
Boom Operation
Use the following procedure to operate the turntable,
boom, or platform functions.
1. Turn the boom speed knob to slow.
2. Place the drive/boom selector switch in the boom
position.
3. Step down on the platform foot switch. This switch
must be held down to operate the upper controls.
4. Hold the appropriate control in the desired direction.
Always look in the direction of movement.
5. Gradually turn the boom speed knob to control
the boom extend, jib and platform rotate function
speed.
6. Releasing the control to its neutral position, or releas-
ing the foot switch will stop movement.
Driving and Steering
A
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive the
machine on grades that exceed 20 percent.
