WARNING
IMPORTANT SAFETY INSTRUCTIONS
1. Work Area Safety
a) Keep your work area clean and well lit. Cluttered or
dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2. Electrical Safety
a) Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodifiedplugs
and matching outlets will reduce risk of electrical shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock
if your body is earthed or grounded.
c) Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
d) Do not abuse the cord. Never use the cord for
carrying or unplugging the power tool. Keep cord
away from heat, oil, sharp egdges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
e) When operating a power tool outdoors, use an
outdoor extension cord suitable for outdoor use.
Use of cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
3. Personal Safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do not
use a power tool while you are tired or under the
infl uence of drugs, alcohol, or medication. A moment
of inattention while operating power tools may result in
serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid shoes, hard hat or hearing protection used for
appropriate conditions will reduce personal injuries.

Always remember that the magnet’s holding power is
directly related to the workpiece thickness and surface
condition. This drill is for use on 3/8" material or thicker.
Since magnetic attraction diminshes with thinner material

EJECTOR ROD ADJUSTMENT
In addition to providing a positive method to insure that a
slug is not retracted with the cutter, the ejector rod serves
as a conduit for the cutting uid and as a centering guide for
positioning the Mag Drill on the workpiece. Under normal
conditions, the point of the ejector rod should be kept at
least 1/16" above the work surface.
It is important that the point of the ejector rod not be
allowed to rest on the work surface for two reasons:
A) The point will drag on the work surface when Mag Drill
is repositioned which may cause the ejector rod to
become bent.
B) The ejector rod may hold the front of the magnet off of
the work surface, deminishing its holding ability.
GEAR COMBINATIONS FOR VARIOUS RPMS

Cover
To adjust the ejector rod:
1. Place the Mag Drill on a steel plate and turn the
magnet on.
2. Loosen the lock nut and rotate the knurled nut until the
point of the ejector rod is in the desired location.
3. When adjusted properly, the point should clear the
work surface (1/16" minimum) both when the magnet
is on and when it is off (Mag Drill riding on glide post).
4. When adjustment is complete, using a wrench,
retighten the lock nut against the underside of the tie
bar.

HINTS FOR SMOOTHER OPERATION
1. Keep the inside of Hougen Cutter clear of chips. Chips will interfere with cutting
to maximum depth, maybe impede the free oil ow 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 uid (preferably
Hougen Cutting Fluid.
5. Occasionally check metering of cutting uid ow. Lack of cutting uid 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 sufciently 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 at 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 uid 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. This will make it difcult to restart the cut.)
#1 cause of cutter
breakage and
prematurely dull
teeth is too little
feed pressure
"Babying" the cutter through the cut will only decrease tool life.
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 at
and/or le imperfections at on the work surface
as needed.
2. Trouble: Cutter tends to move across surface of work.

OPERATION OF CUTTING FLUID RESERVOIR
When everything is ready to go (Magnet ON and Impactors seated), open the Adjustment Needle to provide a generous
ow of cutting uid until a puddle approximately the diameter of the cutter being used is developed on the workpiece.
Once this initial supply of cutting uid is established on the workpiece, adjust the ow to a steady drip.

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.
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 rods, brass gibs, and the feed gear. For best results use Shell Cyprina-RA or equivalent.
5. The safety switch plunger should be clean and lubricated with penetrating oil periodically. As necessary remove the magnet
from drill and remove safety switch assembly from magnet. Push the plunger out of magnet. Clean out any debris from inside an
around plunger hole in magnet. Coat the plunger with anti-seize. Replace plunger and safety switch assembly and tighten down
screws. Replace magnet into drill housing.
