OPERATION
Before operating the machine, ensure that the pre-operation safety inspection has been completed
and that any deciencies have been corrected. Never operate a damaged or malfunctioning ma-
chine. The operator must be thoroughly trained on this machine.
STEERING
NOTE: Steering is not automatically centred. Wheels must be returned to straight ahead position
by operating the steering switch.
1. Select DRIVE mode.
2.
While operating the interlock switch, push the steering switch to right or left to turn the
wheels in the desired direction.
Observe the tyres while manoeuvring the machine to ensure it moves in the correct
direction.
ELEVATING PLATFORM
NOTE: If the chasis 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 low-
ered and the machine moved to a level location before attempting to re-elevate the platform.
1. Check clearances below and to the sides of the platform.
2. Select LIFT mode
3. While operating the joystick interlock switch, push joystick forward to the up position. The fur-
ther you push the joystick, the faster the platform will elevate.
LOWERING PLATFORM
1. Check clearances below and to the sides of the platform.
2. Select lift mode.
3. While operating the joystick interlock switch, pull back on the joystick.
TRAVEL WITH PLATFORM LOWERED
NOTE: The machine’s full travel speed range is enabled when the platform is in the lowered
(stowed) conguration.
1. Check that the route is level and capable of supporting the wheel load, clear of holes and
drop-offs, persons and obstructions.
2. Verify that the chassis key switch is turned to platform control and the chassis emergency stop
switch is on by twisting and pulling the button out.
3. After mounting the platform, ensure gates are close behind you.
4. Check clearances above, below and to the sides of the machine.
5. Be aware of the potential crushing hazards when holding handrails while the platform is mov-
ing in close proximity to other objects.
6. Twist and pull the platform controller emergency stops switch up to the on position.
7. Select drive mode.
8. While operating the joystick interlock switch, slowly push or pull the joystick forward or
reverse to travel in the desired direction.

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.
