Cardi DP2200 MA-16, Safety And Users Manual

Page: 9 / 28

English
The vibrations produced by the tool, if transmitted to
the hands and arms repeatedly in daily work can
cause personal injuries, also using the tool for short
period for many times. The use of a proper drill stand
with
“vibrations suppression” feature
reduces
drastically the level of vibration transmitted to the
operator’s hand
s and arms.
b) Always use the right tool for each job (to do the
job more quickly and expose you to less hand-
arm vibration).
c) Check tools before using them to make sure they
have been properly maintained and repaired to
avoid increased vibration caused by faults or
general wear.
d) Make sure cutting tools are kept sharp so that
they remain efficient.
e) Reduce the amount of time you use a tool in one
go, by doing other jobs in between.
f) Avoid gripping or forcing a tool or work piece
more than you have to.
g) Store tools so that they do not have very cold
handles when next used.
h) Encourage good blood circulation by:
•
keeping warm and dry (when necessary, wear
gloves, a hat, water proofs and use heating
pads if available);
•
giving up or cutting down on smoking because
smoking reduces blood flow; and
• massaging and exercising your fingers during
work break.
6) Throughout the whole operations always use:
Always
wear safety
goggles
Always
wear
safety
gloves
Always wear
ear
protection
Always
wear safety
shoes
Always
wear dust
mask

Service
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.
Instructions before use
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
Warning: this core drill has been designed
for dry use only. Do not use this product in
wet mode.
Choose one of the following drilling techniques according to
the drilling you have to perform. The following hints help you
to choose.
Hand-held drilling
This drilling technique:
▪
is suitable for drilling into abrasive materials like,
bricks, masonry, gasbeton, poroton, etc;
▪
is not recommended to drill concrete (reinforced or
not reinforced);
▪
is not recommended when using the Roto-
Percussion mode
(see chapter
“Rotative and Roto
-
Percussion modes”) .
Drilling with a drill stand
This drilling technique:
▪
is safer and more effective than the hand-held
drilling technique;
▪
is suitable to drill into any kind of material;
▪
allows you to drill in Rotative and Roto-Percussion
modes for longer time than hand-held.
The use of a proper drill stand
with “vibrations
suppression feat
ure”
, is highly recommended.
Always follow the instructions given by the drill
stand manufacturer.
Rotative and Roto-Percussion modes
Your core drill can be used in two modes:
▪
“Rotative mode”;
▪
“Roto
-
Percussion” mode:
while is rotating, the core
bit is also moved forward and backward, generating
impacts on the material you’re drilling
(fig. 2).
You can select the mode by operating the selector as shown
in figure 4.
Warning: The Roto-Percussion mode is not
recommended when drilling hand-held, due
to the vibration level the user is exposed to.
Devices to reduce vibrations
Core drills and more in general every power tool, expose the
user to vibrations that could be dangerous for the health if
prolonged and repeated for significant lengths of time.
The European Directives and Standards for Safety define
limits to time and level of exposure of workers to vibrations.
The employer is responsible for the safety and health of his
workers and he has to evaluate the daily vibrations exposure
taking action when the limits are exceeded.
To reduce the worker’s exposure to vibrations, CARDI
offers
specifically developed devices.
Ask your dealer for more information.
Dust suppression
▪
dry drilling is safer and more effective if dust is
removed by a proper vacuum cleaner;
▪
the core drill is equipped of an integrated dust
extraction system; just connect a proper vacuum
cleaner to the dust outlet;
▪
a proper vacuum cleaner must be suitable for
thin/fine dust;
