INSTRUCTIONS AND PARTS
LIST FOR MODEL 125H & 150H
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:
1. The pump handle is the pressure supply source and is manually operated with an up and
down motion.
2. Item number 45 (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 25 (Part No. 701760), the ram screw can be adjusted into 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 8 INCHES FOR THIS PRESS. EXCEEDING THE STROKE WILL CAUSE
DAMAGE TO THE INNER PACKINGS.
4. The two combination table plates-v blocks provided are used for supporting the work
while it is being straightened.
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 14 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 (14 quarts of oil) with the piston in the top position.

Label 6767
Label 607
Please order all parts by number and name. Also mention model number and serial number
as shown on the plate attached to the frame of the press. Prices for parts do not include
shipping charges.
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.
WARNING LABELS
To the left is the safety Alert symbol. When you see these safety alert symbols
on your press, be 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.

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.
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.
