WARNING!
Read and understand all instructions and responsibilities before operating. Failure to follow safety instructions and labels could result in serious injury.

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.

SAFETY

This is the safety alert symbol. When you see this symbol on your press be alert to the potential for personal injury.
Employer is responsible to perform a hazard/PPE assessment before work activity.
Follow recommended precautions and safe operating practices.

• 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.
• Do not alter this press from its original design.
• Do not make repairs or adjustments to any hydraulic system unless you are competent or working under competent supervision.
• Only use Dake original parts.
• 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.

SET UP

1. Anchor press to floor using 5/8” holes on the base angles of the press.

2. Have an electrician connect starter to power source, pump can rotate in either direction.
   CAUTION: Only a licensed electrician that follows local and state laws is authorized to make an electrical connection to this machine.

3. Remove 3/4” pipe plug and 1/8” pipe plug from side of reservoir, fill with mobile DTE 26 or equivalent hydraulic oil thru 3/4” pipe hole. Fill with oil it reaches the 1/8” pipe tapped hole.

4. CAUTION: Strainer or filter should be used to make sure no contaminants get into reservoir. Replace both pipe plugs.
   Oil capacity: 7 Gallons

OPERATION

RAM MOVEMENT
To raise the ram, turn the release valve handle clockwise, so that the release valve is closed. Then press the raise button to raise the ram. The ram will raise as long as the operator presses the button. Ram movement can be stopped at any time by releasing the raise button.
After the work has been contacted, the press will continue to build pressure as the ram advances, until the press reaches its maximum tonnage. At this point the relief valve will open, allowing oil to return to the reservoir.  To release pressure and lower the ram, turn release valve handle counterclockwise to open the release valve. This permits the oil to return to the reservoir and the ram to lower.

HOIST
The hoist hand crank is provided to raise and lower the upper platen to the proper work height. To change the vertical position of the upper platen, sufficient tension must first be applied to the hoisting cable to permit removal of table pins. Then the upper platen may be raised or lowered to the desired position. All table pins must be inserted once desired position is achieved.

CAUTION: Be sure all the table pins are in place and there is slack in the cable before applying any pressure. It is advisable to lower the top platen opposed to running the lower platen to the end of its stroke.

MAINTENANCE

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.

REPLACING HYDRAULIC OIL
Recommended to replace hydraulic oil every 6 months of machine use. Amount needed may vary dependent on machine use

TROUBLESHOOTING

CAUTION:

• Oil Leaks around the Piston

  • Oil above the piston leather: If rated stroke of the press is exceeded repeatedly by running the piston past rated stroke, bypass hole in the side of the cylinder run bypass line that connects above the piston leather. Eventually enough oil may accumulate so that when the piston is raised to the top of it’s stroke, oil is forced out between the piston and piston guide. This can be remedied by disconnecting the bypass tube line from the cylinder, then raising the piston slowly, about 2-1/2” less than it’s rated stroke (rated stroke: 18”) allowing the oil above the piston cap to overflow out the bypass hole into a clean bucket. Replace tube line. Oil may be put back into reservoir by removing the fill plug on the top of the reservoir.

• Press does not hold pressure

  • Loosen tube connections, check all connections and tighten any loose tube nuts.

  • Dirt under release ball.
    Too correct this condition, remove the release valve rod packing nut, packing, and ball. Clean out the valve seat, reseat the valve ball using brass rod as a drift, tapping lightly. Reassemble valve.
    If this occurs frequently, the oil should be drained from the reservoir, then flush the reservoir to remove any dirt or contaminants. Refill reservoir with mobile DTE 26 or equivalent hydraulic oil. Oil must be filtered carefully to removed and contaminants. Refill reservoir with oil. See “SET UP” section of manual for instructions.

  • Worn leather cup
    If neither of the previous conditions seem to be the cause of the pressure not holding the piston leather may be worn or damaged. To inspect leather, remove the lower platen, then remove cap screws that bolt the piston guide to the cylinder flange. Piston and piston guide may be then listed out of the cylinder and inverted, the leather now can be inspected and replaced in necessary. Reassemble the press, take care not to damage the lip of the leather cup as it enters the cylinder.

• Press will not develop rated tonnage

  • Dirt under release valve ball. See B-2, previously.
  • Worm leather cup. See B-3, previously.
  • Relief valve set low.
    The relief valve has been set at the factory to bypass oil back to the reservoir when the press reaches its rated capacity. However, if the press does not develop rated tonnage and the 2 above conditions have been checked, the relief valve may need readjusting. To do this remove the 1/4” pipe plug in the connector block. The valve adjustment screw should now be accessible and should be adjusted with a 7/32” hex wrench. To increase the setting, turn the adjustment screw clockwise, only adjust screw in small increments before testing tonnage. Be careful not to adjust the valve over its rated tonnage or maximum operating pressure (6000PSI).
    CAUTION: Never exceed 150 tons or operating pressure of 6000 PSI

• No ram movement

  • Release valve open.
    Be sure release valve is firmly closed when operating press.

  • Insufficient oil
    Check oil level in the reservoir when the ram is complete down (rest position). Remove 1/8” pipe plug on side of reservoir. Oil level should reach this hole.

  • Pump loses its prime
    Make sure all intake connections are tight.
    Check to make sure there is enough oil in the reservoir

ELECTRICAL DIAGRAM

HYDRAULIC DIAGRAM

With pump (2) running and valve (4) centered pump (2) delivery is returned to reservoir (7).
For Pressing: valve (4) is shifted, directing pump (2) delivery to bottom of cylinder (6). Ram advances until contacting work, then builds pressure to rated capacity of the press, when press hits capacity then relief valve (3) opens, returning pump delivery to reservoir (7).
For Release: With valve (4) centered, and piston in extended position, release valve (5) is opened, releasing pressure from bottom of cylinder (6). Gravity returns ram to down position.
