MANDATORY RULES FOR THE WORK PLACE
WARNING
The machine operators must start their work only after wearing protective gears
like eyeglasses, ear muffs, and insulated shoes tightened to the legs ensuring
comfortable movement.
SELF PROCTECTION
1. Say no to a messy work environment completely. Keep yourself protected
against fatal accidents by keeping the area clean.
2. In case the floor is wet, stop the usage of the drill machine immediately. You
will expose yourself to the risk of shock if you don't.
3. Only when the surroundings around are brightly lit, use the machine instead
of a dark environment.
4. You should not never place flammable material near the machine or avoid
using the drill machine in the presence of anything flammable. The drill
machine tends to produce sparks in the process of working, which may cause
fire.
Never operate the machine using your feet or remove the slug without wearing
the gloves. Never work towards the maintenance of the circuit board if you
haven't followed all the rules mentioned above.
It is mandatory to read and follow all the safety norms, regulations and
instructions given in this Guide before you operate the machine to avoid
unwanted and fatal accidents. Follow the mentioned workplace safety measures
in the guide strictly to ensure your safety against electric shocks or injuries.
6. Nobody should be in the area where the drill machine is being used by the
Operator.
5. Children should never be allowed near the drill machine, especially when it is
being operated.

MANDATORY RULES TO ENSURE SAFETY
5. Don't press the drill machine too hard as that may lead to an overload,
which tends to shorten the life of the magnetic drill. When in use, be
extremely attentive to the condition of the magnetic absorption of the
drill. Stop using the drill immediately if you notice any instability in the
magnetic absorption.
3. Study this manual well to understand the do's and don'ts of the drilling
tools. They should be used strictly according to the size specified. The
material of the drilling workpiece comes with a magnetized absorption
and works better on a smooth surface. Double check that its thickness
ranges between 10mm-75mm, without the 0.5mm thickness of Iron
scrap and the presence of paint, granular impurities and any other
foreign particles should be avoided.
6. Whenever the drill starts to operate or shuts down, ensure that the
operating sequence of the motor and magnetic switch has been
complied.
8. Do not use drilling machine for not more than a total duration of 30
1. Before starting the drill machine, make sure you inspect the condition of
the power cord and the plug. Replace them immediately if you see any
damage.
2. The power supply should always be in sync with what the equipment
requires. Hence, ensure the same while making sure that safety
measures for grounding and leakage are made available.
4. If the thickness of the drilling machine is less than 10mm, you must
ensure that it is well-supported by iron plates right at the bottom that
come with a thickness higher than 10mm. The supporting iron plate must
have a base area greater than the drilling machine's area of the magnetic
base if you need to improvise the reliability of the capability of the
magnetic base's absorption. In case you opt for a supporting iron plate
which is thinner than the requirement, you will notice the drilling
machine magnet becoming lose in the process of absorption that may
lead to unwanted and fatal accidents.
7. Do not continuously operate the magnetic base with a full load as that
will cast a strong effect negatively on the life of the magnetic base. It may
also get heated up to an extent that it may catch fire. Never touch the
magnetic base, especially when it is extremely hot as that will cause a
serious burn. Turn off the switch and unplug immediately once you stop
using the magnetic base.

11. Only use genuine spare parts and tools as it comes with guaranteed usage
safety.
14. While using the magnetic drill on a particular workpiece, do not do the
process of welding on the same work piece.
15. Use the handle function of the drilling machine to move it from one place to
another instead of pulling the power cable.
13. Even when the equipment stops working, never use your bare hands to
remove the slug after the drilling process as it is very hot.
17. The generation of the magnetic field affects devices such as watches, mobile
phones and pacemaker installed to regulate the heartbeat. Make sure that
the operator takes off the watch and keeps off the mobile phone before
operating the drilling machine and doesn't have a pacemaker installed in him.
16. Switch off the main power supply and unplug the drilling machine after the
usage. If this is not done and the spindle and the tool continue to rotate, then
do not let the operator remove the drill and replace the gear with his bare
hands. Make sure you practice this to avoid injuries.
9. Add a certain amount of coolant to the equipment whenever you replace the
drill. In case you notice a blockage, switch off the motor immediately.
However, you must leave the magnetic base power on. The logic behind this
process is that in case you shut down the power supply of the magnetic base
directly, it may result in the operator suffering from injuries. It will also harm
the motor because of the sudden loss of magnetic force of the magnetic
base.
minutes at a stretch. If done otherwise, it will lead to extreme heat getting
generated that will result in a fire or explosion. Switch off the motor when it is
not in use.
12. Do not remove the drill if the spindle and the drill are in continuous motion.
Unplug the drill from the main power supply to change its gear and never
touch it with your bare hands.
10. Whenever the magnetic drilling machine is in use and is suspended either in a
vertical or a horizontal position, you must get it fixedwith a device that gets
attached to the equipment so that it doesn't come down falling caused by the
sudden loss of power of the magnetic base. When you choose to drill in an
upside-down position, always opt for cutting paste or cutting spray a cooling
method that is reasonable. Say a frank NO to the option of liquid cooling
method as liquid will easily infiltrate into the equipment and result in leakage
of electricity. Instead of liquid cooling method, choose cutting paste or spray
coolant.

ENVIRONMENTAL PROTECTION AND WASTE DISPOSAL
CLEANING AND MAINTENANCE
1. Keep a close check on the bolt of the magnetic drill. It should not be loose and
the gap in the spindle should not be too large. The power cable of the drill
should be in a good condition. You must make sure that the machine is
maintained well.
4. It is always the after-sales service department or the designated dealer who
cater to the maintenance of the drill machine.
5. The operator must clean the magnetic drill after finishing the work, scrub the
side where the drill slides while working and apply lubricating oil on the drill
for the machine to last longer.
7. Switch the machine off and unplug it from the main power socket before you
start the process of maintenance and cleaning.
When it comes to the process of maintenance, inspection and repair pertaining
to their electrical aspects, only a qualified electrician must be contacted to cater
to the task. The qualifications of these electricians change according to their
respective countries. They must follow the effective rules put in place when it
comes to processing, inspection and the maintenance of a Circuit Board in order
to avoid accidents.
3. The lubricating grease in the Gear Box should be changed by a professional
once you have used the drill for three months. Inspect well once the
professional finishes to double check that all the parts have been fully
lubricated.
1. Disposal of the old electrical equipment: Make sure you process the product
in accordance with EC Directive 2002/96/EC-WEEE, also known as Waste
Electrical and Electronic Equipment. In case of doubts or queries, contact the
Department of Waste Disposal.

Operating Manual
WARNING: When drilling in inverted position, cutting oil can enter the motor and can
cause irreparable damage.
TIP: Do not use your magnetic drill on the same structure when ARC welding is in
progress. D.C. current will earth back through the magnet and cause irreparable damage.
TIP: For 100% magnet clamping force you need at least 10 mm of steel. Coatings,
paintings and dirt between magnet and workpiece will affect clamping force.
6. Handy Tips
TIP: When using models with gear and variable speed always select a setting with low
transmission ratio and high motor speed, if possible.
WARNING: After drilling the slug will be ejected and is very hot.
WARNING: When drilling in inverted position, metal swarf can enter the motor. This can
cause irreparable damage and can cause electrical shocks.
WARNING: This appliance must be earthed.
TIP: Most situations which cause problems or question marks have already occurred for
other users. Contact Schifler or your dealer to see if a solution exists for your situation.
(example: for drilling into non-magnetic material with your magnetic drill, a special
vacuum system has been designed).
WARNING: Steel plates of less than 10 mm thickness, coatings, paints and dirt between
magnet and workpiece can affect clamping force and create a possible dangerous
situation. Always make sure your magnetic drill is fastened with the supplied safety chain
and make sure your machine is sufficient attached to the workpiece to start drilling.
TIP: During drilling it is recommended after a certain depth the cutter should be pulled up
on free load in order to permit grease to run across the gear box.
TIP: It is recommended that machine is laid to rest every 30 minutes in order to permit
grease to run across the gear box .
