Check the wheel lug nuts to see that none are missing,
damaged, or loose.
Parking Brakes
Inspect the brake release cam for rust, dirt, and proper
orientation. Make certain the ground strap (refer to Fig-
ure 8.10) is securely fastened to the chassis. It should
be long enough to contact the ground surface to elimi-
nate static electricity from the machine.
Figure 8.10 – Rear of Chassis
Ground Strap
Make certain the ground strap (refer to Figure 8.10) is
securely fastened to the chassis. It should be long enough
to contact the ground surface to eliminate static electric-
ity from the machine.
Lower Control Station
With no personnel in the platform, test the operation of
each control from the lower control station (refer to Fig-
ure 8.11).
Figure 8.11 – Lower Controls
Operating Controls
Use the following procedure to operate the machine from
the lower controls.
1. Turn the battery disconnect switch on.
2. At the lower controls, raise the red cover and push
the emergency stop switch up, to the on position.
3. Insert the key into the control selector switch and
turn the switch to the lower controls position.
A
Danger
Pinch points may exist between moving compo-
nents. Death or serious injury will result from be-
coming trapped between components, buildings,
structures, or other obstacles. Make sure all person-
nel stand clear of the aerial platform while perform-
ing the prestart inspection.
Test the operation of the platform raise/lower switch in
both directions.
Place the battery disconnect switch in the off position.
The platform should not raise or lower with the discon-
nect in this position.
Emergency Stop
Push the red safety guard down over the toggle switch to
turn off the electrical power. The lower control functions
should not operate with the emergency stop in this posi-
tion.
Lowering Alarm and Interrupt
Raise the platform approximately 3 m (10 ′). Lower the
platform and make sure the alarm sounds. The platform
should stop lowering when it reaches about 1.5 m (5 ′).
Release the raise/lower toggle switch to reset the lower-
ing function. Wait for 5 seconds and then push the joy-
stick forward to continue lowering.
Pothole Protector Interlock
Perform this test using the lower controls.
1. Stow the aerial platform on a smooth, flat, level con-
crete slab.
2. Remove all persons and materials from the platform.
3. With the trays closed, check the ground clearance
under the pothole protector skids (refer to Figure 8.12).
Clearance should be at about 8.3 cm (3 1 /
