OPERATION

TRAVEL WITH PLATFORM ELEVATED

NOTE: The machine will travel at reduced speed when the platform is elevated.

1. Check that the route is level and capable of supporting the wheel load, clear of holes and drop-

offs, persons and obstructions.

2. Check clearances above, below and to the sides of the platform.

3. Be aware of the potential crushing hazards when holding handrails while the platform is moving

in close proximity to other objects.

4. While the machine is elevated above 500mm, select “DRIVE” mode.

5. While operating the joystick interlock switch, push joystick to forward or reverse for desired

direction of travel.

6. If the chassis inclination exceeds the specication maximum inclination value, the tilt alarm

will sound and the machine will not lift or drive.

If the tilt alarm sounds, the platform must be lowered and the machine moved to a level

location before attempting to re-elevate the platform.

DRIVE SPEED

The drive speed is proportional to the joystick position. The further the joystick is moved, the faster

the machine will travel. Always slow down before travelling over rough terrain or surfaces.

Drive speed ranges are interlocked via a mast proximity switch which senses the platform position

(Stowed or Elevated).

When the platform elevation (platform oor to oor level) is below approximately 750mm

(29.5”), the full drive speed range is enabled.

When the platform elevation (platform oor to oor level) is above approximately 750mm

(29.5”), only reduced drive speed range is enabled.

Do not use the aerial platform if it drives faster than 0.43km/h (0.27mph) which is 3600mm (17’9”)

in 30 seconds when the platform elevation (platform oor to oor level) is above approximately

750mm (29.5”).

DRIVE/LIFT LEVEL SENSOR INTERLOCK

When the platform elevation (platform oor to oor level) is approximately 750mm (29.5”), lift and

drive functions are interlocked through a level sensor system. If the chassis inclination is greater

than 1.5 degrees side to side or 2 degrees front to back, platform raise and drive functions are

disabled and an alarm sounds when these controls are activated.

If the drive/lift level sensor interlock shuts off the platform raise and drive functions, lower the plat-

form and drive to a level surface.

W A R N I N G

The potential for an accident increases when safety devices do not function correctly. Death or serious injury could

result from such accidents. DO NOT alter, disable or override any safety device.
