SETTING UP THE PRESS FOR OPERATION 

For shipping convenience some of the parts are not assembled.  Assemble these parts in the following order: 

1. Bolt the base angles to uprights using four bolts and nuts, which are provided.  Make sure base

angles are against stops on uprights.
NOTE:  The press should set on a level floor with the base angles touching the floor at all
points.  Use shims where necessary.

2. Switch box is mounted on left upright.  Have electrician connect switch to power line.  Pump can rotate

in either direction.

3. 
4. Oil Requirements:  Fill reservoir thru street elbow at back of press with Mobil DTE oil No. 24 or

equivalent.  NOTE: Oil level may be checked (with ram up) by removing the pipe plug on the
right side of reservoir near the front.  Replace plug before operating the press.

Model 8-025 uses 3 gallons 
Model 8-050 uses 3 gallons 
Model 8-075 uses 3 gallons 
Model 8-150 uses 10 gallons 

5. Attach nose piece to ram by inserting shank into ram and tightening the set screw.

6. 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 when servicing or tracking the cable.  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.
