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.

 

Con

tact

-

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 setting

s

 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

OPERATION

 

The  table  is 

equipp

ed  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.
