and tested prior to shipment. Due to possible damage
in transit the following procedure must be performed
before the equipment is used.
1. Remove all protective covering making certain
that nothing is jammed or fallen into the moving
parts of the table.
2. Inspect the Table for damage in shipment. Be sure
to notify the trucking rm immediately if there is
any damage.
3. All Hydraulic Tables are equipped with a hand
operated oor lock.

stalled into the foot pump lever.
B. OPERATING PROCEDURE FOR HYDRAU-
LIC TABLES
The following instructions apply to the hydraulic
table. Carefully read and understand the procedures
before operating the equipment:
1. Maximum table capacity for the Hydraulic Table
is 2000 lbs. (Rubber wheels 1000 lbs. capacity.)
2. Before loading or unloading table, make sure
the hand operated oor lock is securely locked
against the oor. This requires you to pull up
