1. GENERAL INFORMATION
1.1. Application
The HMSPECIAL140 is a drilling machine designed to drill holes with diameters of up
to 140mm by using annular cutters. The machine can also drill holes with diameters
of up to 47mm by using twist drill bits.
The machine can change the direction of rotation. This allows thread cutting by
using a tap chuck.
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.

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. Let only qualified electrician do the connection to the 115 V power source.
7. Set the MAGNET switch to ‘O’ before you move the machine. Use carrying handle
to move the machine.
8. Do not carry the machine by the power cord and do not pull the cord. This can
cause damage and electric shock.
9. Keep untrained bystanders away from the machine.
10. Before each use, ensure the correct condition of the machine, power source,
power cord, plug, control panel, and tools.
11. 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.
12. Keep the machine dry. Do not expose the machine to rain, snow, or frost.
13. Do not stay below the machine that is put at heights.
14. Keep the work area well lit, clean, and free of obstacles.
15. Make sure that the tool is correctly attached. Remove wrenches from the work
area before you connect the machine to the power source.
16. Do not use tools that are dull or damaged.
17. Unplug the power cord before you install and remove tools. Use protective gloves
to install and remove tools.
18. Unplug the power cord before you manually turn the spindle.
19. Use annular cutters without the pilot pin only when you drill incomplete through
holes. Do not use arbors without a spring.
20. Do not make holes/threads whose diameter or depth differ from those specified
in the technical data.

21. Do not use near flammable materials or in explosive environments.
22. Do not use on surfaces that are rough, not flat, not rigid, or have rust, paint,
chips, or dirt.
23. Do not use if the gibs are adjusted incorrectly.
24. Do not use if there is no grease on the gibs.
25. Do not use the gear switches if the motor is on.
26. 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.
27. Use eye and ear protection and protective clothing. Do not use loose clothing.
28. We do not recommend work on workpieces thinner than 10 mm (0.4″). The
clamping force depends on the workpiece thickness and is much lower for thin
plates.
29. Each time before you put the machine on the workpiece, rub the workpiece with
coarse-grained sandpaper. Make sure that the bottom of the base is in full con-
tact with the workpiece.
30. Do not touch chips or moving parts. Do not let anything catch in moving parts.
31. After each use, remove chips and coolant from the machine and the tool. Do not
remove chips with bare hands.
32. Unplug the power cord before you do maintenance or install/remove parts.
33. Repair only in a service center appointed by the seller.
34. 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.
35. Do not leave the machine when it operates.
36. 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.
37. If you are not going to use the machine for an extended period, put anti-corrosion
material on the steel parts.

3. STARTUP AND OPERATION
3.1. Installing the handles
Attach the handles to the feed shaft. You can install the shaft so that the handles are
on the opposite side of the machine. To do this, lift the motor to the maximum and
continue in the sequence that follows.
1
2 (20 mm, 0.8″)
3 (30 mm, 1.2″)
4
6 (30 mm, 1.2″)

3.4. Installing and removing the screw tap
Install the tap chuck as described before. Next, put the screw tap into the correct
adapter (1). Install the adapter into the tap chuck (2).
To remove the screw tap, unlock it and remove from the adapter.

3.6. Preparing
Before use, clean steel parts, including the MT4 socket, 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 annular cutter, drill bit, or screw tap that matches the required hole
diameter. When you drill holes with diameters of 18–32 mm (0.71–1.26″) by using
twist drill bits, select two bits: with 70% and 100% of the required diameter. When
you drill holes with diameters of 32–47 mm (1.26–1.85″) by using twist drill bits,
select three bits: 18 mm and with 80% and 100% of the required diameter.
Use a dry cloth to clean the spindle, arbor (drill bit, tap chuck), and cutter. Then,
as described before, install the arbor (and then the cutter), drill bit with the smaller
diameter, or tap chuck (and then the screw tap with adapter).
Put the machine on a flat ferromagnetic workpiece with the thickness of at least
10 mm (0.4″). 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. To connect the machine to a 115 V
power source, use the locking connector. Refer to the instructions included with the
connector.
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.
