4. Determine the desired drive range for the specific
driving conditions. Place the drive range handle (refer
to Figure 8.6) in the appropriate position to achieve
the desired drive wheel operation.
• Use high range – Rabbit when traveling across
firm, flat, level surfaces. High range can only be
activated when the platform is stowed. High range
is for high speed, low torque operation.
• Use low range – Turtle for driving on loading
ramps or other steep grades and when safety
considerations demand slow deliberate machine
movement. Low range is for low speed, high torque
operation.

Platform
Use care when entering and exiting the platform to avoid
slipping and/or falling. Fully close the entry gate when the
platform is occupied.
A
Danger
The potential for an accident increases when the fold
down rails are lowered. Death or serious injury can
result in such accidents. Do not elevate the platform
with the fold down rails lowered. Use extreme care
when moving the aerial platform while the fold down
rails are lowered.
Be sure the fold down guardrails are up and the hardware
is securely tightened, 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.
Use the following procedure to raise the platform:
1. Move the aerial platform to a firm, flat, level sur -
face.
2. Place the lift/drive handle in the lift position.
3. Step down on the platform foot valve (refer to Figure
8.7). This valve must be held down to operate the
upper controls.

4. Push the joystick forward to raise the platform.
5. Pull the joystick backward to lower the platform.
6. If the tilt alarm sounds, lower the platform and drive
to a level surface or activate the speed level to level
the platform.
7. Releasing the control to its neutral position, or releas-
ing the foot valve will stop movement.
Driving and Steering
A
Danger
The aerial platform can tip over if it becomes unsta -
ble. Death or serious injury will result from a tip-over
accident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive the
machine on grades that exceed 30 percent.
A fully stowed machine may be operated on grades up
to 30 percent. A grade of 30 percent is a 36 ″ (0.91 m)
vertical rise in 10 ′ (3.05 m) horizontal length.
A
Warning
Death or serious injury could result from improperly
driving or steering the aerial platform. Read and un -
derstand the information in this manual and on the
placards and decals on the machine before operating
the aerial platform on the job.
