Please also observe the relevant national industrial safety regulations. Non-observance of
the safety instructions can lead to an electric shock, burns and/or severe injuries.
This manual should be kept for later use and enclosed with the magnetic drilling machine,
should it be passed on or sold.
Work area
1. Keep your work area clean and well lit. Cluttered and dark work areas increase the
change of accidents;
2. Do not operate a magnetic drilling machine in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. A magnetic drilling machine may create
sparks which could ignite the dust or fumes;
3. Keep bystanders, children and visitors away while operating a magnetic drilling
machine. Distractions can cause you to lose control.
Electrical safety
1. A magnetic drilling machine plug must match the outlet. Never modify the plug in any
way. Do not us any adapter plugs;
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded;
3. Do not expose the magnetic drilling machine to rain or wet conditions. Water entering
a machine will increase the risk of electric shock;
4. Do not abuse the cord. Never use the cord to carry the magnetic drilling machine or
pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords immediately. Damaged cords increase the risk
of electric shock;
5. When operating a magnetic drilling machine, use an extension cord suitable for
outdoor use, this reduces the risk of electric shock;
6. If operating a magnetic drilling machine in a damp location is unavoidable, use a
residual current device (RCD), this reduces the risk of electric shock.

not use oil because the oil can drip into the motor unit;
2. While operating the machine, the annular cutter must be cooled and lubricated with
high quality cutting lubricants;
3. Always remove the slug from the annular cutter after each hole.
WARNING: The metal slug can be sharp and very hot!
4. Use clamps or other practical solutions to secure and support the workpiece to a
stable platform. Holding the workpiece by hand or against your body is unstable and
may lead to loss of control;
5. Do not use the machine when the switch does not turn it on or off. Any machine that
cannot be controlled with the switch is dangerous and must be repaired;
6. 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;
7. Store your magnetic drilling machine out of reach for children and other untrained
persons. Tools are dangerous in the hands of untrained users;
8. Maintain your machine with care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cutting edges are less likely to break and are easier to
control;
9. Check for misalignment of moving parts, breakage of parts and any other condition
that may affect the machine’s operation. If you detect damage have the machine
serviced before use. Many accidents are caused by poorly maintained tools;

3.2 Prior to use
Please make sure that the contacting surface for the magnet is level, clean and rust-free.
Remove any varnish or primer. When working on materials that are not magnetisable,
suitable fixation devices, obtainable as accessories, e.g. suction plate, vacuum plate or pipe-
drilling device must be used. When work on steel materials with a material thickness of less
than 5 mm, the work piece must be reinforced with an additional steel plate in order to
guarantee the magnetic holding power.
Check the machine for possible damage; Before using the machine, you must carefully
check protective devices or slightly damaged components to ensure they are operating
perfectly and as intended. Check that moving are in perfect working order and do not jam
and check whether parts are damaged. All parts must be correctly installed and fulfill all
conditions necessary to ensure perfect operation of the machine. Damaged protective
devices and parts must be repaired or replaced according to specifications by the dealer.
DO NOT use under wet conditions or in presence of flammable liquids or gases. This
magnetic drilling machine is a professional power tool.
DO NOT let children come into contact with the machine. Supervision is required when
inexperienced operators use this machine.
ELECTRICAL SAFETY
The electric motor has been designed for one voltage only. Always check that the power
supply corresponds to the voltage on the rating plate.
Your magnetic drilling machine is designed in class I (grounded) according to EN 61029-1.
Earth wire is required.
If the supply cord is damaged, it must be replaced by a specially prepared cord available
through the service organisation.
EXTENSION CABLE
If an extension cable is required, use an approved 3-core extension cable suitable for the
power input of this tool (see technical data).The minimum conductor size is 1.5 mm² (for
220V) or 14 AWG (Amperage Wire Gauge for 110V). The maximum length is 30 metre
(± 100 ft).
WARNING: When using a reel, always unwind the cable completely!

1. Magnet switch
2. Motor switch

14
4.2 Electromagnet
Make sure the magnetic drilling machine is placed on a smooth, clean, level and solid
surface without any objects or debris in between to guarantee maximum adhesion.
The workpiece must be at least 6 mm (1/4") thick for the magnet to stick, but minimal 3 mm
(1/8") thick to hold the weight of the machine and to drill safely. In case the workpiece is
between 3 mm (1/8") and 6 mm (1/4"), make sure to make a proper base to create a good
magnetic field as shown below.
[image 4-2]
The electromagnet will work best on surfaces of at least 10 mm (3/8") thickness.
The electromagnet may not be able to create a good enough magnetic field. Causes may be:
-Surface not flat
-Workpiece not magnetisable (e.g. aluminium or stainless steel)
-Workpiece coated or painted
-Workpiece not thick enough
Make sure to solve any of these matters before proceeding in any way and creating unsafe
situations.
1. Connect the machine to the mains/work piece;
2. To activate the magnet, press the red magnet switch. It will be lit;
3. To deactivate the magnet, press the same switch again.
It is not a certainly that the magnet will not release from the material. We accept no
liability in case the magnet does not function or functions poorly.

15
Make sure that the magnet attaches tightly to the work piece before turning on the motor unit
of the magnetic drilling machine. Our magnets have 2 coils; make sure that both coils are in
contact with the material. Do not connect any other machines to the electrical outlet the
magnetic drilling machine is plugged into, as it may result in the loss of magnetic force.
Always use the safety chain included. Drilling above your head is extremely dangerous and
is not recommended. For the use of magnetic drilling machines on pipes, not-flat or non-
magnetic materials, you may refer to vacuum tightening systems, pipe clamping systems and
machines with permanents magnets for steel tubes.
4.3 Switching motor on and off
The motor unit can only be switched ON when the magnet is activated. To switch the motor
ON, press the green button with marking “I”. To switch the motor OFF, press the red button
with marking “O”.
4.4 Tool lubrication
HORIZONTAL APPLICATIONS
In order to use the lubrication system, the tank must be filled with a cutting fluid or oil
1. Make sure the flow regulator is closed;
2. Unscrew the cap;
3. Fill the container with cutting fluid or oil;
4. Screw the cap back on.
•Adjust the fluid flow as required using the flow regulator;
•Add more cutting fluid if the shavings (metal chips) become blue.
VERTICAL APPLICATIONS
Dip the cutter in cutting paste or apply an appropriate spray.
WARNING: Do not use the lubrication system in vertical drilling applications. Instead
use cutting paste or spray
Make sure to use only suitable cutting oil or fluid. Proper lubrication will help you create
better and faster results, and extend the lifetime of your tools.

16
5. Working with operation tools
5.1 Annular cutters
Annular cutters only cut material at the periphery of the hole, rather than converting the entire
hole to shavings. As a result, the energy required to make a hole is lower than for a twist drill.
When drilling with an annular cutter, it is not necessary to drill a pilot hole.
WARNING: Do not touch the cutter or the parts close to the cutter immediately after
operation, as they may be extremely hot and cause burns to the skin. Ensure nobody
is in the work area where the metal core is ejected.
DRILLING CONDITIONS
The ease with which material can be drilled depends on several factors including tensile
strength and abrasion resistance. Whilst hardness and/or strength is the usual criterion, wide
variations in machinability can exist among material showing similar physical properties.
The drilling conditions are dependent on requirements for tool life and surface finish. These
conditions are further restricted by the rigidity of the tool and the work piece, lubrication and
machine power available. The harder the material, the lower the cutting speed.
Some materials of low hardness contain abrasive substances leading to rapid cutting edge
wear at high speeds. Feed rates are governed by rigidity of set-up, volume of material to be
removed, surface finish and available machine power.
DRILLING A HOLE
Now that you have read the explanatory information and safety recommendations above, you
are ready to actually start drilling. Follow these 12 steps for best drilling result:
1. Install the annular cutter
-Place the pilot pin into the cutter;
-Align the flat faces on the cutter shank with the screws in the tool holder;
-Make sure the cutter shank is entered fully and correctly ;
-Tighten the screws
[image 5-1]
2. Precisely mark the centre of the hole;
3. Use the pilot pin to position the machine and in the correct position, with the tip of the
pilot pin to meet the marked center of the hole;

17
4. Switch on the magnet and verify that the drill is in the right position and that the
machine is pushed tight against the work piece;
5. If your machine is equipped with a lubrication system, put open the valve to release
the oil. If your machine does not have such a system, fill the holes of the spindle with
oil;
6. Switch the motor on at and allow it to run at the required speed;
7. Turn the arms to start drilling. Apply only a slight pressure when the annular cutter
touch the metal. Do not push the annular cutter with force into the metal;
8. Apply a regular pressure while drilling. The drilling performance does not improve by
putting more pressure on the tool. Too much pressure will overload the motor and
your annular cutter will be worn sooner.
A continuous, non-discoloured iron swarf is a sign of correct drilling speed and
a well-cooled, sharp cutter. Let the cutter do the job and give it time to cut the
metal!!!
9. Adjust the oil supply when necessary, if your drill does not have a lubrication system,
stop drilling regularly, refill the holes of the spindle and continue drilling;
10. Apply less pressure when the drill cuts through the material. The slug will be pushed
out of the cutter by the pilot pin;
11. Turn the arms to put the motor in highest position and switch off the motor unit;
12. Remove the burrs, metal chips and clean the cutter and surface without getting
injuries.
Caution: The slug can be sharp and very hot!!
5.2 Twist drills
Use twist drills with 19.05 mm (3/4") Weldon shank. Align the flat faces on the cutter shank
with the screws in the spindle. Make sure the shank is entered fully and correctly. Fasten the
screws with the provided Allen key.
5.3 Step drills and countersinks
Use step drills for reaming or countersink drills for countersinking with 19.05 mm (3/4")
Weldon shank and follow the steps mentioned in the previous paragraphs.

18
6. Maintenance
Your power tool has been designed to operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends upon proper tool care and regular
cleaning.
CAUTION: To reduce the risk of injury, turn unit off and disconnect machine from
power source before installing and removing accessories, before adjusting or
changing set- ups or when making repairs. Be sure the switch is in the OFF position.
An accidental start-up can cause injury.
Just as every magnetic drilling machine with moving parts, your magnetic drilling machine
also needs regular maintenance service. A few recommendations follow :
VISUALLY CHECK THE MACHINE FOR DAMAGE
Machine must be checked before operation for any signs of damage that will affect the
operation of the machine. Particular notice must be taken of the mains cable, if the machine
appears to be damaged it should not be used failure to do so may cause injury or death.
CLEANING
-Clean all dirt, dust, metal chips and burrs of your magnetic drilling machine;
-Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting
in and around the air vents. Wear approved eye protection and an approved dust mask;
-Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the
tool. These chemicals may weaken the materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get inside the tool; never
immerse any part of the tool into a liquid.
OPERATION OF THE MACHINE
The machines operation must be checked to ensure that all components are working
correctly. Replace any defective parts immediately. This prevents properly function parts
from being damaged.
CHECK MAGNETIC BASE
Before every operation the magnetic base should be checked to make sure that the base is
flat and there is no damage present. An uneven magnet base will cause the magnet not to
hold as efficiently and may cause injury to the operator. When the machine us put out of use
for a longer period, apply a small amount of machine oil to the underside of the magnetic
base for rust protection. Clean the magnetic base again with next use.
CHECK MACHINE GREASE
The gearbox grease should be checked once a month to ensure all moving components are
covered to prevent wear. The grease should be changed at least once a year to ensure you
gain the best from the machine.
CARBON BRUSHES
Brushes should be checked to make sure there is no abnormal wear present. This should be
checked at least once a week if used frequently. If the carbon brush has worn more than 2/3
the original length both brushes should be replaced simultaneously. Failure to do so may
cause damage to the machine.

19
CHECK ARMATURE
This should be checked at least 1 per month to check that there are visual signs of damage
to the body or to the commutator. Some signs of wear will be seen on the commutator over a
period of time this is normal as this is the part that comes in contact with the brushes but any
signs of abnormal damage and the part should be replaced.
ADJUSTMENT OF SLIDE
An essential requirement of the machine is that the slide can move in a smooth and
controlled manner, free of lateral movement and vibration.
This situation can be maintained by periodic adjustment of the slide and is accomplished in
the following manner:
1. Place the machine in an upright position and, by means of the capstan, raise the slide
to its highest position. Clean the aluminum rails and apply a small amount of light
machine oil to the wear surfaces;
2. Gently feed in setting screw with supplied Allen key 2.5 until slight resistance is
encountered. Follow your way down adjusting all setting nuts and screws;
3. Operate the slide up and down a few times to test the movement and make any
further necessary adjustments. Try to ensure that all the screws are exerting a
uniform pressure on the slide from top to bottom. A perfectly adjusted slide will
operate freely up and down without any sideways movement.
LUBRICATING THE FEED TRAVEL
The feed travel should be lubricated periodically with grease to ensure smooth operation.
-Raise the motor unit to the highest position possible;
-Lubricate the dove-tail guide way at both sides;
-Lubricate the gear rack.
After repeated use, the gear rack may become loose. If necessary, adjust the self-locking set
screws at the left side. Tighten screws in series until the gear rack moves freely in the dove-
tail guide but does not allow the motor to wobble.
REPAIR, MODIFICATION AND INSPECTION
Repair, modification and inspection of magnetic drilling machines must be done by the
manufacturer or an authorised dealer. The spare parts list will be helpful if presented with the
machine to the dealer for service when requesting repair or other maintenance.
Our machines are constantly being improved and modified to incorporate the latest
technological advancements. Accordingly, some parts (i.e. part numbers and/or design) may
be changed without prior notice. Also, due to our continuing program of research and
development, the specifications of machines are subject to change without prior notice.
