Site Layout, Shipping Weights, and Unloading of Major Components

------ WARNING! ------

Personal injury or death can result from lifting a heavy assembly.

The heavy assembly can fall if using an incorrect hoist to lift the load.

Be sure the hoist has the correct capacity to lift a heavy assembly. Approximate weight of the assembly is given below.


------ WARNING! ------

Personal injury or death can result from improper lifting or blocking.

When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component.

Approximate weights of the components are shown. Clean all surfaces where parts are to be installed.


Choose a flat, drained area for assembly. The area should have the following dimensions: 24 m (78 ft) long by 24 m (78 ft) wide.

Note: Do not open the bags of hardware. The bags of hardware are marked for easy identification and for orderly use.
