in personal injury.
Avoid unintentional starting. 7. Make sure you are prepared to begin work before
squeezing the handle on the Air Valve (40A).
Avoid off-center loads. 8. If the Pressure Head Assembly (22A) seems unusually
hard to press, immediately stop the operation. Disconnect the Shop Press from its
compressed air supply source, and adjust the workpiece to eliminate or diminish
an off-center load. Do not operate the Shop Press if the workpiece tilts or binds
during the down movement of the Pressure Head Assembly.
Prior to lowering the Pressure Head Assembly (22A) remove tool trays, stands, 9.
and all other tools and equipment from the Press Table (6A).

secure the workpiece with clamps (not provided).
Once contact between the pressure head and workpiece has been made, 13.
step away as far as possible and continue to slowly apply pressure until the
procedure is complete.
Never leave a compressed workpiece unattended. 14. When a workpiece is com-
pressed, there is a large degree of force that has been stored in the workpiece, this
must be controlled until the Pressure Head Assembly is released.
Keep the Shop Press properly filled with hydraulic oil. 15. For instructions, see
“Inspection, Maintenance, and Cleaning” section in this manual.
