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 PACKINGS.

 

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.
