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 flow of lubricant 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 RotaMagic Cutting Fluid)
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 suffi-
ciently 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, 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:
No power.
Remedy:
Check power source and extension
cords.
d. Cause:
Worn motor brushes.
Remedy:
Replace brushes.
e. 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.
