MY PUMP WON'T RUN...

Machines this applies to: 2800, 3200, 3200MCD, 960, 975, 985

  1. Newer models of the 3200/975/985 are equipped with a switch at the top of the delivery table support chain on the non-operator side of the chain delivery.  Its purpose is to stop the paper feed (by shutting off the pump) if the delivery table gets too low.  Many times this switch gets gummed up with oil and powder and will no longer reset itself when the table is cranked back up.  If the pump was running fine but fails to run after you stop to unload the delivery dolly this may be your problem.  If your switch fails just unplug the connector and tuck it through the hole in the frame.  The press will run fine and the switch can be repaired at a more convenient time.
  1. Be sure the pump switch is off and see if you can turn the pump pulley at the bottom of the press by hand.  If the pump is very difficult to turn you may be able to free it up by doing the following:
    1. Remove the filter jar and filter just inside the access panel below the feed table.
    2. Squirt some WD-40 into the hole that is next to the filter mounting screw in the filter assembly.
    3. Immediately try to turn the pump by hand again with the switch off.
    4. If this loosens it up try turning the switch on again.
    5. Once you get the motor running squirt some light oil (10-20 wt.) up into the same hole.  The oil is very important - if you don't do this the pump will probably seize up.  Remember, WD-40 is not a lubricant.
    6. Reinstall  the filter and jar.
    7. You may want to do a complete pump flush at a convenient time.
