1. GENERAL INFORMATION
1.1. Application
The PRO 55 is a drilling machine designed to drill holes with diameters of up to 55
mm by using annular cutters. The machine can also drill holes with diameters of up to
18mm by using twist drill bits. It also allows machining holes with diameters of up to
55 mm by using countersinks.
The electromagnetic base clamps the machine to ferromagnetic surfaces. This
makes sure that the operator is safe and the machine works correctly. A safety strap
protects the machine from falling in case of a clamping loss.
Accessories allow you to drill in pipes and clamp the machine to flat non-
ferromagnetic surfaces.

2. SAFETY PRECAUTIONS
1. Before use, read this operator’s manual and complete a training in occupational
safety and health.
2. Use only in applications specified in this operator’s manual.
3. Make sure that the machine has all parts and they are genuine and not damaged.
4. Make sure that the specifications of the power source are the same as those
specified on the rating plate.
5. Connect the machine to a correctly grounded power source. Protect the power
source with a 16 A fuse for 230 V or a 32 A fuse for 115 V. If you are going to work
on building sites, supply the machine through an isolation transformer with class II
protection only.
6. Set the MAGNET switch to ‘O’ before you move the machine. Use carrying handle
to move the machine.
7. Do not carry the machine by the power cord and do not pull the cord. This can
cause damage and electric shock.
8. Keep untrained bystanders away from the machine.
9. Before each use, ensure the correct condition of the machine, power source,
power cord, plug, control panel, and tools.
10. Before each use, make sure that no part is cracked or loose. Make sure to main-
tain correct conditions that can have an effect on the operation of the machine.
11. Keep the machine dry. Do not expose the machine to rain, snow, or frost.
12. Do not stay below the machine that is put at heights.
13. Keep the work area well-lit, clean, and free of obstacles.
14. Make sure that the tool is correctly attached. Remove wrenches from the work
area before you connect the machine to the power source.
15. Do not use tools that are dull or damaged.
16. Unplug the power cord before you install and remove tools. Use protective gloves
to install and remove tools.
17. Unplug the power cord before you manually turn the spindle.
18. Use annular cutters without the pilot pin only when you drill incomplete through
holes.
19. Do not drill/machine holes whose diameter or depth differ from those specified in
the technical data.
20. Do not use in explosive environments or near flammable materials.

21. Do not use on surfaces that are rough, not flat, not rigid, or have rust, paint,
chips, or dirt.
22. Do not use if the gibs are adjusted incorrectly.
23. Do not use if there is no grease on the gibs.
24. Do not use the gear switch if the motor is on.
25. Use the safety strap to attach the machine to a stable structure. Put the strap
through the hole in the machine body. In the horizontal position, attach the strap
to the carrying handle. Do not put the strap into the buckle from the front.
26. Use eye and ear protection and protective clothing. The clothing must not be loose.
27. We do not recommend work on workpieces thinner than 6 mm (0.24″). The clamp-
ing force depends on the workpiece thickness and is much lower for thin plates.
28. Each time before you put the machine on the workpiece, rub the workpiece with
coarse-grained sandpaper. Make sure that the full bottom of the base touches
the workpiece.
29. Do not touch chips or moving parts. Do not let anything catch in moving parts.
30. After use, clean the machine and the tool. Do not remove chips with bare hands.
31. Unplug the power cord before you do maintenance or install/remove parts.
32. Repair only in a service center appointed by the seller.
33. If the machine falls, is wet, or has any damage, stop the work and immediately
send the machine to the service center for check and repair.
34. Do not leave the machine when it operates.
35. If you are not going to use the machine, remove the tool from the holder. Then,
remove the machine from the work area and keep it in a safe and dry place.
36. If you are not going to use the machine for an extended period, put anti-corrosion
material on the steel parts.

3.5. Monitoring system of the clamping force
The drilling machine has a system that monitors the clamping force of the electro-
magnetic base. The force will be lower if there is rust, paint, chips, or dirt. The force
will be lower also if the surface is thin, rough, not flat, not rigid, the voltage is lower
than required, or the bottom of the base is worn.
If the clamping force is too low, the system will not allow the machine to operate.
Then, after you release the green MOTOR button, the motor stops. This happens on
a surface thinner than 5 mm (0.2″). The clamping force is then only about 25% of the
force that you can get on a flat plate that is 25 mm (1″) thick. To drill on thin plates
then, press and hold the green MOTOR button.
3.6. Preparing
Before use, clean steel parts, including the spindle, from anti-corrosion material used
to preserve the machine for storage and transport.
Attach the handles to the feed shaft. You can install the shaft so that the handles
are on the opposite side of the machine.
Apply a thin layer of grease to the gibs.
Select the tool that matches the required hole diameter. Use a dry cloth to clean
the spindle and the tool. Then, install the tool as described before.
Put the machine on a flat ferromagnetic surface with the thickness of at least
6 mm (0.24″). Make sure that there is no rust, paint, chips, or dirt. They decrease the
clamping force. The force will be lower also if the surface is thin, rough, not flat, not
rigid, the voltage is lower than required, or the bottom of the base is worn.
Connect the machine to the power source. Set the MAGNET switch to ‘I’ to turn
on the clamping. Some types of steel (non-ferromagnetic) do not conduct magnetic
flux so the machine cannot clamp onto them.
Use the safety strap to prevent fall and injury if the machine loses the clamping.
Attach the machine to a stable structure by putting the strap through the hole in the
machine body. In the horizontal position, attach the strap to the carrying handle.
Make sure that the strap is tight and not twisted. If the machine comes loose from the
workpiece and hangs on the strap, replace the strap. Do not put the strap into the
buckle from the front.

Turn the handles to the left to put the tool tip above the workpiece.
For vertical drilling with an annular cutter, install the cooling system and fill it with
coolant. Do not use only water as the coolant. But you can mix water and drilling oil.
Then, make sure that the cooling system works correctly. To do this, lightly loosen
the bottle cap and use the lever to open the valve. Then, turn the handles to the left
to apply a light pressure on the pilot pin. The coolant should fill the system and start
flowing from the cutter.
The cooling system works by gravity. Thus, in the horizontal position, turn the bottle.
In the inverted position, use coolants under pressure or in the form of spray or paste.

Steel with a strength Rm≥500 N/mm2(70,000 psi), such as St5 (E295), 18G2A
(S355N), or 45 (C45), requires lower speeds. If the speed is too high or too low for
the workpiece strength and the type/diameter of the tool, the tool will wear faster or
be unable to drill the hole.

Press the green MOTOR button to start the motor. Turn the handles to the left to
put the tool into the workpiece.
When the annular cutter goes through the workpiece, the slug
core is pushed out with a large force.
When you use an annular cutter, drill only through holes. For incomplete through
holes do not use the pilot pin.
Keep the machine in the same position until the hole is made.
If you are going to drill holes deeper than 50 mm (2″), retract the tool from the
workpiece as often as possible. This allows chips to be removed from the hole. If the
grooves of the tool are clogged, turn off the motor and use a brush to clean them.
After you get to the depth of 40 mm (1.6″), retract the tool from the workpiece as
often as possible. Then, manually apply the coolant from the bottle into the drilling area.
After the hole is made, retract the tool from the workpiece, and press the red
MOTOR button to turn off the motor. Before you move the machine, set the MAGNET
switch to ‘O’ to turn off the base.
After the work is finished and the motor turned off, set the gear switch to the
opposite position. Then, turn on the motor and let it operate for a while with no load
to improve lubrication. Next, turn off the motor and the base, and then unplug the
power cord. Clean the machine and the tool, and then remove the machine from the
work area.

Tighten the bottle cap, close the valve, and then press the pilot pin to remove the
coolant that remains in the cooling system. Before you put the machine into the box,
remove the bottle, and use gloves to remove the tool from the holder.
3.8. Adjusting the gibs
Every 50 work hours, make sure that the gibs are correctly adjusted. To do this,
move the motor up and down and make sure that it moves smoothly.
To adjust the gibs, apply a thin layer of grease on them. Then, use the 8 mm
combination wrench, the 2.5 mm hex wrench, and the 5 mm hex wrench to loosen
the nuts and screws (1). Put the motor so that the slider is in the center of the gibs
(2). Then, lightly tighten the screws (3) so that they touch the gib. Move the motor up
and down and adjust the screws (3) so that the travel is smooth. Next, tighten the
screws (4) and then tighten the nuts (5).
