MAINTENANCE

In order to minimize wear on moving parts and to insure smoother operation and longer life for your magnetic drill,
the following maintenance should be done periodically, based on use.

1.  Regularly tighten all fasteners and replace all worn parts.
2.  Check motor brushes and replace if worn. (Break in period - 30 minutes at no load speed)
3.  Check power cord and cord from panel to motor and, if cracked or frayed, return to an authorized repair center for
     replacement.
4.  Apply grease to the slide dovetails, brass gibs, and the feed gear rack. For best results use Shell Cyprina-RA or
     equivalent.
5.  Remove arbor and pack the bearing in the front support bracket with grease. Use Shell Cyprina-RA or equivalent.

HINTS FOR SMOOTHER OPERATION

1.   Keep insides of Hougen Cutter clear of chips. Chips will interfere with cutting to maximum depth, may impede
      the free oil flow and can cause cutter breakage.
2.   Keep work, machine, arbor and Hougen Cutter free of chips and dirt.
3.   Tighten all bolts and fasteners regularly.
4.   We highly recommend using a light viscosity cutting fluid (preferably
      Hougen Cutting Fluid - Part No. 11742-4)
5.   Occasionally check metering of cutting fluid flow. Lack of cutting fluid may
      cause Hougen Cutter to freeze in cut, slug to stick and may result in poor
      cutter life.
6.   Always start cut with light feed pressure and then increase sufficiently to
      achieve maximum cutting rate.
7.   Ease off on pressure as cutter begins to break through at the end of the cut.
8.   Keep slide dovetails, brass gibs and feed rack lubricated and free of chips and dirt.
9.   When slug hangs up in cutter, turn off motor and bring cutter down on a flat surface. This will normally straighten a
      cocked slug, allowing it to be ejected.
10. When cutting large diameter or deep holes it may be necessary to stop in the middle of the cut to add cutting
      fluid and remove the chips from around the arbor. (When doing this DO NOT raise the cutter out of the hole.
      Doing so can allow chips to get under the teeth of the cutter and make it difficult to restart the cut.)

REMEDIES FOR HOLEMAKING PROBLEMS

1. 

Trouble:   Magnetic base won’t hold effectively to work

.

      a.  Cause:

 Chips or dirt under magnet.

           

 Remedy

:  Clear area of chips and dirt.

      b.  Cause:

 Irregular surface on bottom of magnet
 or on workpiece.

          

   Remedy:

 Lightly surface grind the bottom of the
 magnet flat and/or file imperfections
 flat on the work surface as needed.

2.  Trouble:  Cutter tends to move across surface

      of work.

      a.  Cause:

Magnetic base not holding effectively.

           

Remedy:

See causes and remedies under No. 1
above.

      b.  Cause:

Too much feed pressure at start of cut.

            

Remedy:

  Light pressure until a groove is cut.

The groove then serves as a stabilizer.

      c.  Cause:

Worn pilot.

         

  Remedy:

Replace pilot

3.  Trouble:   Out of round holes.

      a.  Cause:

Worn arbor support bracket bearing
and or ejector collar.

          

 Remedy:

Replace: (only a few thousandths
wear permissible.)

      b.  Cause:

Misaligned  support  bracket

           

Remedy:

Realign support bracket

4.  Trouble:   Motor and slide won’t stay in set position

     a.   Cause:

Gibs  too  loose

           

 Remedy

:   Adjust gibs

5. 

 Trouble:   Erratic or intermittent feed.

        a. Cause:

Worn or pinion and/or rack.

         

    Remedy:

Replace worn parts.

6.   Trouble:    Motor doesn’t run when motor START
       button is pushed.

       a. Cause:

Magnet is not turned on

          

  Remedy

: Push magnet ON button.

       b. Cause:

Magnet on rough or dirty work surface
and safety switch not fully depressed.

          

  Remedy:

File work surface flat and clean all
chips and oil from under magnet.

       c. Cause:

Safety switch out of adjustment

         

   Remedy:

Adjust safety switch

       d. Cause:

No power

          

  Remedy:

Check  power source and extension
cords.

        e. Cause:

Worn motor brushes

          

  Remedy:

Replace brushes

        f. Cause:

Faulty motor START switch

            

Remedy:

Return unit to an authorized repair
center to have switch replaced.

NOTE: If you are unable to correct any malfunction
after trying the above, do not attempt to operate the
drill. Return the unit to the factory or authorized
repair center for service.
