SAFEGUARDING THE POINT OF OPERATION
ANSI B11.2 – Hydraulic Power Presses
Safety Requirements for Construction, Care and Use
It is important that Dake press users have a clear understanding of their responsibility involving the care and use
of their Dake hydraulic press, including point-of-operation safe guards. Dake strongly recommends that Dake
press users obtain a copy of the current American National Standard Institute (ANSI) B11.2 standard, for a
more complete understanding of their responsibilities.
ANSI B11.2 states the following, relative to point of operation safeguarding:
“Normally, only the employer (press user) can determine the requirements of the press productions system
components, including the dies and methods for feeding. There fore, the employer is ultimately responsible to
designate and provide the point-of-operation safeguarding system”.
The standard also discusses additional responsibilities of the employer. Some of the key responsibilities are:
•
The employer is responsible for the safety, use and care of the hydraulic power press production system.
•
The employer is responsible to consider the sources of hazards for all tacks to be implemented on the
hydraulic power press production system.
•
The employer is required to eliminate or control identified hazards in the scope of their work activity.
•
The employer is responsible for the training of personnel, caring for, inspecting, maintaining and
operating hydraulic press production systems to ensure their competence.
•
The employer is responsible to provide and ensure that point-of-operation safeguarding is used, checked,
maintained and where applicable, adjusted on ever production operation performed on a press
production system.

FILLING THE PRESS WITH OIL
It is extremely important that new, clean, light hydraulic oil be used in this press, Mobil DTE 24 or an
equivalent. It is strongly recommended that the oil be filtered to remove any possible dirt. The piston should
be in its maximum upper position when filling the reservoir. Fill the reservoir with 3 quarts of oil. UNDER NO
CIRCUMSTANCES USE OLD DIRTY OIL. Next remove the screw plug from the gauge extension on top of
the workhead, close the release valve handwheel and pump oil into the workhead until oil is visible in the stand
pipe. This will remove all air from the chamber above the piston. If oil leaks by the piston, the reservoir
should be drained and refilled (3 quarts of oil) with the piston in the top position.
