3. USE GUIDELINES
The device is designed to make through holes and blind
holes in mineral building materials such as e.g. concrete,
all types of walls, asphalt, all types of screed, natural stone,
using appropriate drills.
The user is liable for any damage resulting from
unintended use of the device.

3.2. PREPARING FOR USE
3.2.1. APPLIANCE LOCATION
Ensure good ventilation in the room in which the device
is being used. Keep the product away from hot surfaces.
The device should always be used when positioned on an
even, stable, clean, fireproof and dry surface, and be out of
the reach of children and persons with limited mental and
sensory functions. Position the device such that you always
have access to the power plug. The power cord connected to
the appliance must be properly grounded and correspond to
the technical details on the product label.
3.2.2. BEFORE FIRST USE
1. Power source. Ensure that the power source which is
utilized conforms to the power requirements specified
on the product name.
2. Power switch. Ensure that the power switch is in the
OFF position. If the plug is connected to a power
receptacle while the power switch is in the ON
position, serious accidents can occur.
3. Extension cord. When the work area has no power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be kept
as short as possible.
4. Make sure that the coolant is connected to the
machine through a 16 mm diameter tube. Lack of
water may cause damage to the device. The maximum
allowable liquid pressure is 0.12 MPa.
NOTE: Do not use contaminated water.
3.2.3. ASSEMBLING THE DEVICE
INSTALLATION OF THE COOLING FLUID HOSE AND THE
DRILLS
• Coolant feed hose assembly: Slide hose end over
device coolant feed valve. Once on, use a hose clamp
to secure the hose in place.
• Mounting a core drill on the device. To mount a core
drill on the spindle, screw it on clockwise.
3.3. CHECKING THE DEVICE
1. Inspecting the tool.
Since the use of a dull tool will cause the motor to
malfunction, it should be replaced with a new one
without delay when abrasion is noted.
2. Inspecting the mounting screws.
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
3. Maintenance of the motor.
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Inspecting the carbon brushes.
The motor employs carbon brushes which are
consumable parts. When they become worn or near
the "wear limit", it could result in motor trouble. When
an auto-stop carbon brush is equipped, the motor will
stop automatically. At that time, replace both carbon
brushes with new ones. In addition, always keep
carbon brushes clean and ensure that they slide freely
within the brush holders.

3.4. DEVICE USE
WARNING! If an unusual smell or smoke appears
during operation, please turn off the device
immediately.
Attach the drill bit and connect the water supply. Before
turning the device on, make sure that the lowest speed is set.
Connect the device to power and turn it on without load. If
it is working properly, open the water valve and when water
flows out the machine may start working with a load. When
changing speed, stop the machine. After finishing work, turn
it off, close the coolant valve and pull out the mains plug.
ATTENTION! When working, make sure that the core drills
are not in the workpiece.
WARNING! If the rotation speed starts to drop while
drilling, it means the motor is overloaded.
WARNING! The engine must not be flooded with
water or oil.

3.5. CLEANING AND MAINTENANCE

a) Unplug the mains plug and allow the device to cool
completely before each cleaning, adjustment or
replacement of accessories, or if the device is not
being used.
b) Use only non-corrosive cleaners to clean the surface.
c) Store the unit in a dry, cool place, free from moisture
and direct exposure to sunlight.
d) Do not spray the device with a water jet or submerge
it in water.
e) Do not allow water to get inside the device through
vents in the housing of the device.
f) Clean the vents with a brush and compressed air.
g) The device must be regularly inspected to check its
technical efficiency and spot any damage.
h) Use a soft, damp cloth for cleaning.
i) Do not use sharp and/or metal objects for cleaning
(e.g. a wire brush or a metal spatula) because they
may damage the surface material of the appliance.
j) Do not clean the device with an acidic substance,
agents of medical purposes, thinners, fuel, oils or
other chemical substances because it may damage
the device.
k) Do not wipe any plastic parts with solvents. Solvents
such as gasoline, thinner, benzene, alcohol, ammonia
and oil may damage and crack the plastic parts. Do
not wipe them with such solvents. Wipe the plastic
parts with a soft cloth lightly dampened with soapy
water.
REPLACING CARBON BRUSHES
When the device is operated, carbon brushes steadily wear
out. When the insulation tip integrated inside the brush gets
revealed and touches the commutator it will trip the engine
automatically. When this happens, both brushes must be
replaced with new brushes of the same type. Inspect the
carbon brushes after approx. 300 working hours. When the
brushes are worn down to a length of about 7 mm, they
should be replaced.
ATTENTION! BEFORE COMMENCING CARBON-BRUSH
REPLACEMENT, make sure the device is switched off and
the power cord is unplugged.
Replacing the carbon brushes:
1. Unscrew the screw securing the carbon brushes on
the side of the device housing.
Rev. 06.10.2020
2. Remove worn out carbon brush, insert new brush and
tighten the screw. Replace the carbon brush on the
other side of the housing in an analogous manner.
