INSTRUCTIONS AND PARTS
LIST FOR MODEL 50H
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. 716519), 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 4 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.
