SAFETY GUIDELINES:
Material handling is dangerous. To reduce the
likelihood of injury to person or property:
•Read this manual in its entirety before installing,
using and maintaining this table for the first time!
The capacity of your table is based on a uniformly
distributed, centered load. DO NOT exceed the
capacity because permanent damage and/or personnel
injury could result. Contact the factory for side-loading
and end-loading capacities.
•DO NOT lower the unit onto the maintenance prop(s)
while the table is loaded.
•DO NOT go under the platform unless the
maintenance prop is in position.
•ONLY use AW-32 hydraulic oil (or equivalent), or
Dexron II transmission fluid in the tables reservoir. Do
not use brake fluids or jack oils.
•Check the settings and conditions of all safety
switches and stickers frequently.
•Never operate the table if it (or any component) is
in need of repair. Tag the unit "Out-of-service" and
notify maintenance personnel if, during operation, any
unusual noises, movements, or noticeable damage to
the understructure of controls, or if the table fails to
respond normally to control commands.

OPERATION

The table is equipped with a "dead man"
style push button controler. This type of operation,
also called "push-to- run", allows the operator to
move the deck of the table as much or as little as
necessary.
The air motor of the power unit requires a
minimum air supply of 70 CFM at 70 PSI.
