WARNING! Read and understand all instruction before operating any drilling system. Failure to
follow all instructions listed below may result in electrical shock, damage to drilling system and
even personal injury.
GENERAL SAFETY INSTRUCTIONS
Work area
Keep your working area clean and well lighted. Cluttered benches and working stations
causes accidents as well as dark spaces. Always ensure working stations are clean and well lit.
Do not operate power tools in explosive atmosphere, such as in the presence of flammable
liquids, gases or extreme dust. Power tools create sparks that may ignite gases as well as
flammable liquids. Dust may enter the ventilation system causing clogging and causing
overheating.
Keep bystanders, children and visitors away from moving parts of the power tool. Any
distractions can cause you to loose control of the power tool and an injury could take place.
Electrical Safety
Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the ground prong or modify the
dance plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if
you are in doubt as to whether the outlet is properly grounded. If tools should electrically
malfunction or break down, grounding provides a low resistance path to carry electricity away
from the user.
Never carry a tool by the cord or hose and “yanking” the cord or the hose to disconnect it
from the receptacle. Always carry the power tools properly and store in dry and dust free
place.
Keep cords and hoses away from heat, oil and sharp edges. Damaged cords increase the risk
of electric shock.
Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.

PORTABLE MAGNETIC CORE DRILLING SYSTEM
When operating a power tool outside, use an outdoor extension cord marked .W-A. or. W..
These cords are rated for outdoor use and reduce the risk of electric shock.
Personal Safety
Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment
of inattention while operating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts.
Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your
finger on the switch or plugging in tools that have the switch on invites accidents.
Remove adjusting keys or switches before turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in personal injury.
Do not overreach. Keep a proper footing and balance at all times. Proper footing and
balance enables better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hardhat,
or hearing protection must be used for appropriate conditions.
Tool use and care
Use clamps or other practical way to secure and support the work piece to a stable platform.
Holding the work by hand or against your body is unstable and may lead to loss of control.
Do not force tool. Use the correct tool for your application. The correct tool will do the job
better and safer at the rate for which it is designed.
Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the
tool accidentally.

5
PORTABLE MAGNETIC CORE DRILLING SYSTEM
Store idle ling tools out of reach of children and other untrained persons. Tools are dangerous
in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with
sharp cutting edges are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tools operation. If damaged, have the tool serviced before
using. Poorly maintained tools cause many accidents.
Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used on another
tool.
Service
Only qualified repair personnel must perform tool service. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
When servicing tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of electric shock or injury.

PORTABLE MAGNETIC CORE DRILLING SYSTEM
SPECIFIC SAFETY RULES AND REGULATIONS
Always use safety chain. Mounting can release.
The magnet’s adhesion depends on the thickness of the work piece. Always ensure that the
work piece is a minimum of 12mm (7/16 in.) thick. If it is not, then use a piece of steel plate at
least12mm thick and larger than the magnet below the work piece to supplement the
magnetic adhesion.
Metal chips and other debris will seriously hamper magnetic adhesion. Always ensure that the
magnet is clean.
Other units used on the same receptacle will cause uneven voltage that could lead to the
magnet releasing. Always use the tool alone on the receptacle.
It is hazardous to use the drill upside-down. Do not exceed 90 degrees from horizontal.
Avoid the magnet releasing. Ensure that the magnet has properly adhered to the work piece
before beginning drilling.
Avoid operating annular cutters without coolant fluid. Always check coolant level before
operating.
Do not operate with dull or damaged cutting tools. This may overload the motor.
Protect the motor. Never allow cutting fluid, water, or other contaminants enter the motor.
Metal chips are often very sharp and hot. Never touch them with bare hands. Clean up with a
magnetic chip collector and a chip hook or other appropriate tool.
CAUTION: NEVER position machine on a work piece between the electrode and the ground of
any arc type welder. Damage to the machine will result, as the welder will ground
through the machine’s ground cable.
WARNING: NEVER attempt to use machine with incorrect current or abnormally low voltage.
Check machine nameplate to ensure that correct voltage and Hz are used.

PORTABLE MAGNETIC CORE DRILLING SYSTEM
ASSEMBLY
Coolant tank assembly required. First attach clear tube to the bottom of the coolant tank. To
do this, first loosen the nut and slide nut onto the tube. Then slide tube onto the nipple. Then
tighten the nut. Slide tank hanger over the screw on the upper right hand side of slide and
tighten. Finally insert the other end of the tube into the quick-release connector in the
gearbox. Just directly push in to install. (To remove, first firmly push the red collar of the
connector and pull the tube out.) Cutting coolant fluid is always required when using annular
cutters. Open tank cover and fill. Check coolant fluid level often. Keep coolant tap closed
when not in use.
Chip guard must be used. To attach the chip guard, use the supplied butterfly bolts to bolt to
the magnet. It is not necessary to remove guard to clean chips. Simply raise guard to its upper
position.
Safety chain must be used. Loop chain around the work piece and feed through the
machine’s handle and clip in place.
MOUNTING ANNULAR CUTTERS
CAUTION: Never use a cutting tool that is larger than the maximum rated capacity of the
machine.
1. To insert an annular cutter, first insert the pilot pin into the
cutter. Then slide the cutter into the arbor, align the proper
flat with the locking screw(s) and tighten securely with the
supplied hex wrench.
CAUTION: Ensure that the locking screw is on a flat of the cutter and not just against the
rounded shank.
2. Ensure that the oil feed tap is on and coolant feeds properly by pushing the pilot pin. If it
feeds too quickly or slowly, adjust the tap accordingly. Keep the tap closed when not in use.

9
SPECIAL INSTRUCTIONS FOR 4-SPEED MT3 EQUIPPED MODELS
CHANGING TOOLS & ADAPTORS WITH MT3 SHANK
To insert a tool, turn the tool until the tang lines up and firmly
push into place. It is helpful to tap with a soft-faced mallet to
fully engage the taper. If it is properly in position, one will not be
able to pull it back apart by hand. To remove, line up the
ejector slot of the arbor with the ejector port in the gear case,
slide the ejector drift into the slot and tap with a hammer to
eject the tool.
CAUTION: When removing, take care that the cutting tool
does not crash down and get damaged or injure
anyone below.
MT3 ANNULAR CUTTER ADAPTOR
This machine is equipped with a unique annular cutter adaptor system with built-in coolant
directly to the gearbox. No stop bar is needed.
1. To install the annular cutter adaptor, first insert the taper end of the adaptor into the arbor of
the machine as described above.
2. Attach the coolant tank to the slide and ensure that the tube is attached properly.
3. To insert an annular cutter, first insert the pilot pin. Then slide the cutter into the adaptor,
align the proper flat with the locking screw(s) and tighten securely with the supplied
hex wrench.
4. Ensure that the oil feed tap is on and coolant feeds properly by pushing the pilot pin. If it
feeds too quickly or slowly, adjust the tap accordingly. Keep the tap closed when not in
use.
OPERATION
The operation instructions under “OPERATION-GENERAL” also apply to this machine. Please see
the additional instructions specific to the 4-speed Morse taper model below:
PORTABLE MAGNETIC CORE DRILLING SYSTEM

10
PORTABLE MAGNETIC CORE DRILLING SYSTEM
WARNING: NEVER operate 60mm (2-3/8 in.) or larger cutters unless the plate thickness is mini
mum 20mm (13/16 in.) MAGNET LIFTING MAY RESULT. If the plate thickness is not
enough, supplement the magnetic adhesion by adding a 10mm or thicker plate
directly the magnet’s position under the work piece.
CAUTION: Machine is equipped with a reversing switch. Always ensure that direction of
rotation is correct before operating. Operating in the wrong direction could result
in damage to the cutter.
Select desired gear range by first popping the tab out of its detent
and then sliding selectors up or down in the proper combination.
Refer to the chart to achieve the correct combination for the
desired speed. (It may be necessary to turn the arbor slightly in
order for the gears to mesh properly). Follow the recommended
speed ranges on the cutting speed chart to set the proper speed
and gear range.
NOTE: These speeds are general recommendations only. The material should determine actual
speeds and the cutting speed recommended by the cutting tool manufacturer.
NOTE: the left and right side gear selectors have a different engagement design:
For The LEFT HAND SLIDER must ALWAYS ensure that the machine is FULLY STOPPED before
attempting to change gears! NEVER change the Left hand slider gears on a running machine!
4 SPEED GEAR CHART:
GEAR NO LOAD SPEED FULL LOAD SPEED CUTTERS TAPS

11
PORTABLE MAGNETIC CORE DRILLING SYSTEM
For the RIGHT HAND SLIDER the gears select by engagement dogs, similar to a motorcycle
transmission design. These MUST BE SELECTED BY TURNING THE ARBOR to allow the dogs to
engage. They may also be engaged while the motor is running, provided that it is not under
load.
Select desired direction of rotation. This switch has 3 positions:
up is forward, middle is neutral, and down is reverse rotation.
WARNING: If the motor is switched on with the direction switch in the
neutral position, the machine will not turn but will be
“live”, as soon as either forward or reverse is selected,
the arbor will begin turning! Take due care to avoid
surprises. This in NOT the proper order of operations.
Proper order of operations for normal drilling (not
tapping) is as follows: magnet: on. direction: forward.
motor: on. motor: off. magnet: off.
TWIST DRILLS
NOTE: A pilot hole may be necessary when drilling with larger twist
drills. If a MT3 twist drill is used, it may not be necessary to
remove the arbor support bracket.
CHUCK
If a MT3 chuck adaptor & chuck are used, then the bracket must
be removed.
To replace, see the instructions above under
“ARBOR SUPPORT BRACKET REPLACEMENT”.
TAPPING
CAUTION: To avoid damage to the tap, always very carefully line the tap up with the hole and
ensure that the size of the hole is correct for the tap to be used.

12
CAUTION: To avoid damage to the tap or machine, be very
careful to stop the machine in time to NOT allow the tap
bottom out. The motor continues to coast for a while
after being shut off, so plan for this and anticipate.
This machine does NOT have a clutch.
CAUTION: To avoid damage to the machine, ALWAYS allow the machine to come to a full stop
before reversing rotation.
1. Select the proper speed according to the chart for the size of tap used.
2. Begin with forward direction of rotation with standard right hand threads.
(Opposite with left-hand threads)
3. Allow the tap to determine the feed rate. A light touch on the feed handle is all that is
needed once it is started in the hole.
4. When the desired thread is tapped, hit the red motor stop switch. Allow the machine to
come to a full stop. Then reverse direction and restart machine by pressing the green motor
switch to remove tap. Guide the tap back out with the feed handle. Proper order of
operations for normal tapping is as follows: magnet: on. direction: forward. motor: on. motor:
off. THEN: direction: reverse. motor: on. motor: off - magnet: off.
MAINTENANCE
1. Keep the machine clean and free of chips.
2. Check for loose fittings and tighten as needed.
3. Ensure that the ventilation slots are clear so that motor can be cooled normally. Blow
low-pressure compressed air through the ventilation slots with the motor running to keep
motor clean.
THE ARBOR SHAFT
Keep the arbor shaft free of dirt and lightly grease as needed. If the arbor support bearing is
noisy, it may be dirty or have a chip lodged in it. Remove the arbor shaft to clean and
re-grease the arbor support bearing.
PORTABLE MAGNETIC CORE DRILLING SYSTEM

13
THE GIBS (DOVETAIL SLIDES)
The gibes require adjustment if too loose. To adjust, loosen the lock
nuts and adjust the adjustor screws evenly while moving the handle
up and down. Adjust so that there is no free play, yet any binding
anywhere in its range of travel. Then retighten the lock nuts.
Periodically check, lubricate, and adjust as needed.
PORTABLE MAGNETIC CORE DRILLING SYSTEM
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and must be replaced when they reach their
wear limit.
Caution: Always replace the brushes as a pair.
To replace:
1. Remove the 4 screws and remove the motor tail cover.
2. Using pliers rotate the brush spring out of the way and slide
the old carbon brush out of the brush holder.
3. Unscrew the screw to remove the brush lead. The old
carbon brush may now be lifted away.
4. Install a new brush. Installation is the reverse of removal.
5. Replace the motor tail cover.
AUTO STOP CARBON BRUSH
Due to the new auto stop carbon brush if the machine comes
to a stop without any reason, the brushes have to be
checked. The auto feature stops the machine before the
carbon brushes are finished and protects the motor.
