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. Therefore, 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 tasks 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 every production operation performed on a
press production system.
A complete and current copy of the ANSI B.11.2 standard can be obtained by contacting the following:

SAFETY
Employer is responsible to perform a hazard/PPE assessment before work activity.
Follow recommended precautions and safe operating practices.
Additional Warnings:
•Carefully read all safety messages in these instructions and on your press safety
signs.
•Keep safety labels in good condition. Replace missing or damaged safety labels.
•Employer is responsible to perform a hazard/PPE assessment before work activity.
•Do not alter this press from its original design.
•Do not make repairs or adjustments to any hydraulic system unless you are competent

•This machine is intended to be operated by one person. This person should be
conscious of the press ram movement not only for themselves but also for persons in the
immediate area of the machine.
•Tag out procedures must be followed by authorized employees as per OSHA.
•Hydraulic – Relieve all hydraulic pressure before servicing the press. Turn the red
release handle to relieve the pressure
•Spring Pressure – Clamp ring on bottom of piston must be in place before removing
cylinder.
•Hoist and table channel – always place table pins under the table channels then install
the remaining pins. Always release pressure on the cable before using press.

SET UP
For shipping convenience, the gauge, pump handle, hoist crank, screw nose and base angles
were removed from the press. Assemble these parts to the press in the following order:
1. Bolt the base angles to the uprights using the four bolts and nuts furnished. Shoulder the
base angles against the stops on the uprights.
2. The press should be set on a level floor with the base angles touching the floor at all
points, using shims where necessary. Then secure the base angles to the floor using
four, 1/2” bolts included.
3. Install the pressure gauge using the hydraulic sealant to ensure a sealed fit.
4. Insert the pump handle into the handle socket and fasten in place by means of the set
screw on top of the handle socket.
5. CAUTION! Place the hoist crank on to the lift drum shaft. Remove the table pins and
turn the crank to get the table to a desired height. Check to make sure the hoist cable is
tracking correctly. Run the table channels from top to bottom, the cable should be on
each of the two upper pulleys and should track back and forth on the cable drum.
b. If a tracking problem exists, contact the Dake factory for instructions.
6. Fasten nosepiece to the end of the screw using the thumbscrew included.
FILLING PRESS WITH OIL
Recommended to replace hydraulic oil every 6 months of machine use.
IMPORTANT! ONLY FILL WITH NEW, CLEAN, LIGHT HYDRAULIC OIL. UNDER NO
CIRCUMSTANCES USE DIRTY OIL.
1. Use Mobil DTE 24 or equivalent.
2. Filter the oil to remove any possible dirt.
3. Put the piston in to its maximum upper position.
4. Fill the reservoir with 3 quarts of oil.
5. Remove the screw plug from the gauge extension on the top of the work head.
6. Close the release valve handwheel and pump oil into the work head until oil is visible in
the standpipe.
a. This will remove all air from the chamber above the piston.
If oil leaks by the piston, the reservoir should be drained and refilled with the piston in the
maximum upper position.

OPERATION
CONTROLS
Hand Crank: (Part No. 701653) on the side of the press is to assist in lowering and raising the
table of the press once the table pins are removed. Do not forget to replace the pins once you
have the table at the desired height.
Head Positioning Handwheel:can be loosened to allow the head to move along the upper
frame track and can be positioned at any length on the top frame. After in position, tightening
the handwheel completely will keep the head in place.
Handle:(Part No. 218) is the pressure supply source and is manually operated with up and
down motion. IMPORTANT! Always pump the piston down 1/2" before the nose piece meets the
work. Damage to the piston may occur if not pumped before meeting the work.
Release Valve Handwheel: releases the pressure to let the ram return to its raised position.
Always keep the valve firmly closed when operating the press until you want to release the
pressure.
Screw Handwheel: (Part No. 716519) raises or lowers the ram screw in and out of the piston
assembly. Always keep the portion of the screw extending out of the piston as short as possible.
Instead of overextending the screw it is recommended to raise the table rather than running the
screw out of its limit of travel. NEVER EXCEED THE RECOMMENDED STROKE OF 4 INCHES
FOR THIS PRESS. EXCEEDING THE STROKE WILL CAUSE DAMAGE TO THE INNER
PACKINGS.
MAINTENANCE
Recommended to replace hydraulic oil every 6 months of machine use.
LUBRICATION
•Keep all working parts of the press well-oiled for easier operation.
•Keep a light film of oil over the entire surface of the ram to prevent rust.
TROUBLESHOOTING
PUMP PACKING LEAKAGE
If oil leaks past the pump packing, tighten the pump packing nut (Part No. 551A) until the pump
handle moves with resistance, then slack off just enough to cause the handle to stay in position
by itself. After long periods of operation, it may be necessary to install new pump packings.

PRESS NOT HOLDING PRESSURE
This condition is nearly always caused by dirt under the pressure ball valve (Part No. 586). See
hand pump assembly drawing.
Steps to fix:
1. Remove the reservoir drain plug and drain all oil out of the reservoir.
2. Remove parts: pipe plug (Part No. 588), check valve spring (Part No. 579) and ball valve
(Part No. 586) then clean out the port hole and valve seat thoroughly.
3. Using a small piece of brass rod as a drift, tap on the brass rod lightly to seat the ball
valve in place.
4. Replace the spring and plug with extreme care to prevent dirt from entering.
5. Replace the drain plug and refill the reservoir with clean filtered oil.
See FILLING PRESS WITH OIL section in manual.
