handling and control of the tool in unexpected
situations.
5) Service
a)
Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

1) Safety instruction for all operations
Always
wear safety
goggles
Always
wear safety
shoes
a)
Use the auxiliary handle. Loss of control can
cause personal injury.
b)
Brace the tool properly before use. This tool
produces a high output torque and without properly
bracing the tool during operation, loss of control
may occur resulting in personal injury.
c)
Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting accessory may contact hidden
wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
2) Safety instructions when using long drill bit
a)
Always start drilling at low speed and with the
bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting in
personal injury.
b)
Apply pressure only in direct line with the bit
and do not apply eccessive pressure. This can
provoke a loss of control, resulting in personal
injury.
3) Safety instructions when using a drill stand
a)
When the bit is jammed, stop applying
downward pressure and turn off the tool.
Investigate and take corrective actions to eliminate
the cause of the bit jamming.
b)
When
restarting
workpiece, check that bit rotates freely before
starting. If the bit is jammed, it may not start, may
overload the tool, or may cause the drill stand to
release from the workpiece.
c)
When securing the drill stand with anchors and
fasteners to the workpiece, ensure that the
anchoring used is capable of holding and
restraining the power tool during use. If the
workpiece is weak or porous, the anchor may pull
out, causing the drill stand to release from the
workpiece.
d)
When securing the drill stand with a vacuum
pad to the workpiece, install the pad on a
smooth, clean, non-porous surface. Do not
secure to laminated surfaces such as tiles and
composite coating. If the workpiece is not
smooth, flat or well affixed, the pad may pull away
from the workpiece.
e)
Ensure there is sufficient vacuum level before
and during drilling. If the vacuum level is
insufficient, the pad may release from the
workpiece.

f)
Never perform drilling with the drill stand
secured by the vacuum pad only, except when
drilling downward. If the vacuum is lost, the pad
will release from the workpiece.
g)
When drilling through walls or ceilings, ensure
to protect persons and the work area on the
other side. The bit may extend through the hole or
the core may fall out on the other side.

Read carefully the data reported on the data plate
of your core drill and on the Technical Data sheet
that you will find in the package together with
your product.
In the following text, figures are identified by numbers,
details inside the figures by letters. Figures are depicted on
the first pages of this user manual.
Drilling technique choice
dry drilling is more effective and safer if dust is
▪
removed by an industrial vacuum cleaner. In
particular you must remove the dust if you drill
vertically downwards;
▪
if you want to remove the dust with an industrial
vacuum cleaner, make sure that your core drill is
equipped with the dust extraction integrated device
(see figure 2) that allows you to connect your core
drill to an industrial vacuum cleaner. Otherwise use
a proper accessory, called dust extraction device
(figure 2 Q), that can be mounted to the front part of
the core drill;
the industrial vacuum cleaner must be suitable for
▪
thin dust;
always wear a dust mask when performing dry
▪
drilling.
Choose one of the following drilling techniques according to
the material you want to drill and according to the diameter
and the length of the hole you want to make.
Hand-held dry drilling
this technique is suitable for drilling into abrasive
▪
materials like tiles, gasbeton, poroton, concrete,
the
reinforced concrete;
Drilling with a drill stand
this drilling technique is safer and more effective
▪
than the hand-held drilling technique;
this technique is suitable when you want to make
▪
holes with diameter below the maximum drilling
diameter reported on your product, into any kind of
material. In particular you must use a drill stand if
you are drilling outside the limits defined before for
hand-held drilling.
Power supply
▪
when you have to operate with your core drill far
from an electrical socket, you can use an extension
cord. If you use it make sure that the section of the
cord is suitable and that the cord is provided with
ground conductor;
▪
the extension cord (made up of cable, plug and
socket) must be suitable for outdoor use. It is better
if the cord is made of rubber and it is H07RN-F;
