Preparation and Set-up

1. DO NOT alter or modify the work platform in any manner.

2. Make sure that the work platform is securely attached to the quick attach or

forks. Follow the platform manufacturerís instructions.

3. Make sure the platform, carriage and forks are secured to prevent them

from pivoting from side to side.

4. On side tilt or swing carriages, the carriage must be centered and/or lev-

eled horizontally and vertically. The hydraulic system quick disconnects
must also be disconnected and plugged and the carriage securely fastened
to prevent any tilting or side to side swinging motion.

5. Ensure the vehicle has a firm footing and is level.

6. Be sure the vehicle is in a level position (side to side) before any operation

is begun. Use the frame sway to level the vehicle. If the vehicle cannot be
leveled, reposition the vehicle.

8. Engage the parking brake switch. Blocking the wheels is also recom-

mended.

before use.

10. Before lifting or lowering personnel, be sure the vehicle lifting mechanism

operates smoothly through the entire lifting and lowering of the platform
and maintains its self leveling function. The vehicle must operate smoothly
both empty and loaded.

11. Be sure any lift limiting devices and latches are functioning properly.

12. Any body belt, lanyard or deceleration devices which have sustained any

deformation or damage must be replaced before using the work platform
again.

13. Before elevating personnel, the area around and under the work platform

should be marked to warn anyone on the ground that overhead work is
being done.

14. Protection must be provided for the personnel on the work platform from

any pinch points or moving parts while in their normal working position on
the platform.

15. Provide any overhead protection device as required by worksite conditions

or if requested by the user of the platform.
