Elec-Draulic I Presses: Set Up, Trouble Shooting, And Maintenance

Set Up, Trouble Shooting, And Maintenance Hydraulic Press

As promised, here is part three in the series “Dake presses, set up, trouble shooting and maintenance.” This press we are going to be looking at is our famous Elec-Draulic I series. Its self-contained workhead design goes back many years with trouble-free service. You don’t have to pump it up manually and it gives you plenty of smooth efficient pressure with joystick operation. Well, let’s move on and get this press set up so you can be making parts or squishing things in short order. As efficient as this press is, it won’t set itself up, so lets’ get started.



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.

  1. Motor starter box is mounted on left upright. Have electrician connect power to motor starter. Pump can rotate in either direction. (That saves time being rotation is always right the first time.)
  2. 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 1/8” NPT pipe plug on the right side of reservoir near the front. Replace plug before operating the press.

Model 5-025 uses 6 quarts

Model 5-050 uses 8 quarts

Model 5-075 uses 10 quarts

Model 5-150 uses 20 quarts

  1. Prime pump by removing the plug in the top of the pump opposite the intake line and allow the oil levels in the reservoir and pump to equalize. Fill pump with additional oil (if required), replace plug making sure seal is tight, and start motor.
  2. Attach nose piece to ram by inserting shank into ram and tightening the set screw.

CAUTION! Place the hoist crank on the lift drum shaft. Turn the hoist crank to relieve the pressure on the table pins. Keeping tension on the hoist crank, remove the table pins one at a time. After removing the tables pins, turn the crank running the table channels from top to bottom. Check to make sure the cable is tracking correctly. 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.



CAUTION: When disconnecting any parts of this machine be extremely careful that all parts are clean to prevent entrance of dirt in the hydraulic system.

For in depth trouble shooting and repair please refer to your owner’s manual or go to the manuals section of our website for details on SYMPTOM CAUSE SOLUTION. This will save you time and keep you safe when making repairs.

Next in our series we look at the brute force of hydraulic presses the Elec-Draulic II, with our double acting workhead. Until then, check out the details of this press on our website.
