Drive/Lift Level Sensor Interlock

When the platform is elevated above 2.1 to 2.4 m (7 to 8

feet), lift and drive functions are interlocked through a

level sensor system. If the chassis is tilted more than

two degrees side-to-side or four degrees front-to-rear, plat-

form raise and drive functions are disabled and an alarm

sounds when those controls are activated.

If the drive/lift level sensor interlock shuts off the platform

raise and drive functions, lower the platform and drive to a

level surface.

Platform raise and drive functions may also be disabled

by the pothole protection interlock.

Steering

The steer control switch is located on the joystick (refer

to Figure 9.2). Use the following procedure to steer the

aerial platform using the upper controls.

1. Squeeze and hold the interlock switch against the

joystick.

• To turn to the left, tap lightly on the left side of the

steer switch.

• To turn to the right, tap lightly on the right side of

the steer switch.

Note

Holding the steer switch down too long may result in a

sharp turn. This is especially true when driving and steer-

ing at the same time. It may be easier to turn the wheels

in small increments using a series of quick taps on the

steer switch.

2. Set the steer wheels straight ahead after completing

a turn. The steering wheels are not self-centering.

Platform

Use care when entering and exiting the platform to avoid

slipping and/or falling. Make certain the entry gate is prop-

erly pinned in position. Fully lower the gravity gate when

the platform is occupied.

ADanger

The potential for an accident increases when the

swing-down rails are lowered. Death or serious in-

jury can result from such accidents. Do not elevate

the platform with the swing-down rails lowered.

Be sure the swing-down rails are up and the pins are all

installed, anytime the machine is not being transported.

Raising and Lowering

The raise speed is proportional to the joystick position.

The farther the joystick is moved, the faster the platform

raises. There is only one lowering speed.

1. Place the drive/lift selector switch (refer to Figure 9.2)

in the lift position.

2. Squeeze and hold the interlock switch against the

joystick.

• To raise the platform, slowly pull the joystick back

until the desired speed is reached.

• To lower the platform, slowly push the joystick for-

ward.

Lowering Interrupt

When the platform is lowered to about 1.5 m (5′) lowering

stops. The platform will not lower for five seconds regard-

less of the joystick position.

Center the joystick in neutral to reset the lowering func-

tion, then continue to lower the platform.

Overload Protection

When the load in the platform is near or at rated capac-

ity, an alarm will sound and the red light on the upper

controls (refer to Figure 9.3) will flash.

Figure 9.3 – Upper Controls

The alarm and light warn the operator that the platform is

close to becoming overloaded. All functions remain fully

operational.

ADanger

The aerial platform can tip over if it becomes un-

stable. Death or serious injury will result from a tip-

over accident. Do not exceed the capacity values

indicated on the platform rating placard.
