Product Usage Instructions

When using the Dake hydraulic press, it is of utmost importance to ensure the safety of the point of operation. Users are responsible for understanding and complying with the necessary precautions and safe guards. Dake strongly recommends obtaining a copy of the current American National Standard Institute (ANSI) B11.2 standard for a comprehensive understanding of responsibilities.
The ANSI B11.2 standard provides guidance on point of operation safeguarding. According to the standard, the employer (press user) holds the responsibility to determine the requirements of the press production system components, including dies and feeding methods. Therefore, it is the employer’s duty to designate and provide an appropriate point-of-operation safeguarding system.
The employer has additional responsibilities as outlined in the ANSI B11.2 standard. It is essential to review these responsibilities and ensure compliance for a safe working environment.
To obtain a complete and current copy of the ANSI B11.2 standard, individuals can contact the American National Standards

SETTING UP PRESS FOR OPERATION

The press is shipped completely assembled.

Place 25 & 50 ton presses on pedestal 33″ high (44-001). 75 ton presses on pedestal 19″ high (44-003).
258 a is nos ang unite sion press must be wired into customer’s power supply.
Connect hose from the water line to the water valve on the right hand side of the press.
Connect drainage hose or pipe to manifold on the left side of the press. 5. The press is now ready for operation.

OPERATING INSTRUCTIONS

Switch on current by means of the toggle switches and platens will start to heat up.
Heat is adjusted by turning the thermoswitch knobs in the back of each platen. Counterclockwise rotation increases the heat. Check temperature by reading thermometer in front of platens.
Place material to be processed between platens. 4. Close release valve on left side of base by turning handle clockwise.
Bring platens in contact by pushing pump handle away from you until it stops.
Push pump handle downwards for high pressure operation.
Continue this pumping, reading the platen pressure on the gauge, until the desired pressure is reached.
To open press, turn release valve handle in counterclockwise direction.

MOLDING INSTRUCTIONS

The mold is heated by the platens.
The mold may be bolted to the platens or placed on the platens without any permanent fastening.
The mold must be self-guided.

LAMINATING INSTRUCTIONS
For instructions on laminating with vinyl plastic sheets contact DAKE. When using other types of laminating material contact the manufacturer who has technical data available.

Material not specifically made for laminating should be coated with adhesive compound before beginning process.
Place material to be laminated highly polished plates and blotters.
Apply a pressure of approximately 250 P.S.I. and heat approximately 3 minutes. Pressure, temperature and heating time varies with the type of material being used.
For absolutely flat, clear laminations, cooling should take place in the press under pressure. Some work may be cooled outside the press; test the job on outside cooling to see if the finished product meets specifications.
In the 4-platen press, material may be heated by the upper platens at the same time that other material is being cooled under pressure by the lower platens.

ADDITIONAL INFORMATION

Check oil level in base tank. Oil level should be at ½ inch from bottom edge of rear hand hole. If oil supply is down, replace with Mobil D.T.E. heavy medium (D.T.E. 26) or its equal. Reservoir capacity – 25 ton press – 6 quarts; 50 ton press – 12 quarts; 75 ton – 24 quarts.
If operation requires more daylight, remove the ram adapter from top of ram by lifting up platen resting on it.
Do not exceed pressure rating of press.
Do not allow red warning marks on ram to go above top of cylinder.
The electrical heating can be shut of on any platen by means of the individual toggle switches at left of pressure gauge.
Pilot light is on when platen heater is operating. If pilot light goes out, the thermoswitch has cut the heating current.
Servicing of pump and cylinder is achieved through the opening at the rear of the base.
To cool platens, turn off toggle switch and open water valve gradually so as to prevent too rapid a change in temperature.

MAINTENANCE

If press loses pressure
- Check the release valve (item 27) to see if it is closed tight.
- Check all tube lines for leaks and tighten them.
- Check cone check valve (item 11) to see if O-ring (item 12) is in good condition.
- Check packings (item 6, 8 and 38) in pump and ram for wear or damage.

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.
