ADanger

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 emergency stop button in to turn off the electri-

cal power. The lower control functions should not operate

with the emergency stop in this position.

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′).

ing function. Wait for 5 seconds and then push the joy-

stick forward to continue lowering.

crete slab.

Tires and Wheels

Visually inspect the tires (refer to Figure 8.9). They should

be smooth without any cuts, gouges, or missing rubber

that might affect aerial platform stability.

Figure 8.9 – Tires and Wheels

Check the wheel lug nuts to see that none are missing,

damaged, or loose.

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.
