INSTRUCTIONS AND PARTS

LIST FOR MODEL 25H

HAND-OPERATED HYDRAULIC PRESS

SETTING UP THE PRESS FOR OPERATION

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. Install the pressure gauge using a hydraulic sealant to ensure a sealed fit.

3. Insert pump handle into handle socket and fasten in place by means of the setscrew on top of the handle
socket.

4. CAUTION! Place the hoist crank on the lift drum shaft. The table is raised to the desired height by

turning the crank after removing the table pins. 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. Always place table pins under
the table channels before releasing the hoist crank when positioning the table channels for cable
tracking, servicing, or set-up for desired work opening. If a tracking problem exists, contact the
Dake factory for instructions. Be sure all table pins are fully inserted in place before applying
pressure. Always remove or release pressure on the cable before pressure is applied.

5. Fasten nosepiece to the end of the screw using the thumbscrew included.

OPERATIONS AND CONTROLS

The operator should acquaint himself with the use of the following controls:

A. Insert 4 table pins
B. Close release valve
C. Leave a gap of ½” between bumper and reservoir
D. Keep portion of screw extending beyond the ram as short as possible

1. The pump handle is the pressure supply source and is manually operated with an up and down motion.

2. Item number 41 (part no.10631) is the release valve handwheel. Always keep it firmly closed when
operating the press and it should only be opened when releasing the pressure to allow the ram to return.

3. By turning Item 33 (Part No. 716518), the ram screw can be adjusted in or out of the piston assembly.
Always keep the portion of the screw extending out of the piston as short as possible. It is advisable to
raise the table one or two sets of holes rather than running the screw out to its limit of travel. NEVER

EXCEED THE RECOMMENDED STROKE OF 5 INCHES FOR THIS PRESS. EXCEEDING THE
STROKE WILL CAUSE DAMAGE TO THE INNER P ACKINGS.

4. The two combination table plates-v blocks provided are used for supporting the work piece.

5. Always pump piston down ½” before nose piece comes in contact with work. Damage to piston may
occur.

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 2 ½ quarts of oil. UNDER
NO CIRCUMSTANCES USE OLD DIRTY OIL. Next remove the screw plug from the top of the cylinder and fill
with oil. Close the release valve handwheel and pump oil into the workhead until oil is visible in the top of the
cylinder. This will remove all air from the chamber above the piston. Then install the gauge. If oil leaks by the
piston. The reservoir should be drained and refilled (2 ½ quarts of oil) with the piston in the top position.

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 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 B11.2 standard can be obtained by contacting the following:

alert to the potential for personal injury.

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. This machine is

intended to be operated by one person. This person should be conscious of the press ram movement not

only for himself but also for persons in the immediate area of the machine.

Additional warnings

• Employer is responsible to perform a hazard/PPE assessment before work activity.

• Do not make repairs or adjustments to any hydraulic system unless you are competent or working

under competent supervision. If in doubt consult a qualified technician or engineer

• Only use Dake original parts

• Do not alter this press from the original design.

• Tag out procedures must be followed by authorized employees as per OSHA.

* Note: If press leaks around the ram but holds pressure the reservoir has been overfilled.

HYDRAULIC – Relieve all hydraulic pressure before servicing press. Turn the red release handle to relieve

pressure.

SPRING PRESSURE – Clamp ring on bottom of piston must be in place before removing cylinder.
GRAVITY – Hoist & table channel. Always place table pins under the table channels first then install remaining

pins. Always release pressure on the cable before using press.

TROUBLE SHOOTING – DAKE HAND HYDRAULIC PRESSES

PUMP PACKING LEAKAGE

If oil leaks past the pump packing, tighten the pump packing nut (551) until pump handle works hard, 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.

LUBRICATION

Keep all working parts of the press well oiled for easier operation. Also keep a light film of oil over the entire
surface of the ram to prevent rust.

IF PRESS DOES NOT HOLD PRESSURE

This condition is nearly always caused by dirt under pressure ball valve part number (586). See workhead
assembly drawing. To remedy this condition, first remove the reservoir drain plug and drain off all the oil in the
reservoir. Next, remove parts, 3/8” pipe plug (588), check valve spring (579) and valve ball (586) then clean
out port hole and valve seat thoroughly. Replace and using a small piece of brass rod as a drift, tap the brass
rod lightly to seat the ball properly. Replace spring and plug using extreme care to prevent dirt from entering.
Replace the drain plug and refill the reservoir with clean filtered oil.
If above procedure does not correct the condition, air may be present in the chamber above the piston and
should be removed as directed in Filling Press with Oil paragraph III.
