3. With the trays closed, check the ground clearance

under the pothole protector skids (refer to Figure 8.12).

Clearance should be at about 10.1 cm (4″) on both

sides of the aerial platform.

4. Raise the platform while watching movement of the

skids. The skids should lower to approximately 2.5

cm (1″) ground clearance when the platform is raised

approximately 61 cm (24″).

5. Fully lower the platform while watching movement of

the skids. The skids should raise to their stowed

position, with about 10.1 cm (4″) ground clearance,

when the platform is fully lowered.

6. Place a 3.8 cm (1

″) thick board, such as a 2 x 4,

under the skid on the left side (refer to Figure 8.13).

7. The board will prevent the skid from lowering fully.

Raise the platform. When the skid contacts the board,

the platform should stop raising and an alarm should

sound at approximately 2.1 to 2.4 m (7 to 8 feet)

platform floor height. The alarm should then sound

when the platform lift switch is activated and the plat-

form should not raise.

8. Lower the platform. Place the board under the skid

on the right side.

9. Raise the platform. When the skid contacts the board,

the platform should stop raising and an alarm should

sound at approximately 2.1 to 2.4 m (7 to 8 feet)

platform floor height. The alarm should then sound

when the platform raise switch is activated and the

platform should not raise.

AWarning

The potential for an accident increases when safety

devices do not function properly. Death or serious

injury can result from such accidents. Do not alter,

disable, or override any safety device.

10. If the platform raise function is not disabled, or the

alarm does not sound remove the aerial platform from

service until the problem is corrected.

Emergency Lowering

Using the lower controls, fully raise the platform. Locate

the emergency lowering handle (refer to Figure 8.14) at

the rear of the aerial platform.

Figure 8.14 – Rear of Chassis

While standing clear of the scissors structure, pull the

handle out and the platform will begin to lower. Push the

handle in to stop. Make certain the handle is all the way

back in after lowering the platform.

Structures

Visually inspect all mechanical structures including the

weldments and related components. It is important to in-

spect the fasteners that connect the components.

Weldments

Visually inspect all weldments for abnormal wear, abra-

sion, or deformation that could cause interference between

moving parts.

Inspect the welds on the structural components. The area

to be inspected should be clean and free of dirt and grease.
