LINK TO WATER TAP
For the cooling of the machine, always use the original machine water pipe that has a security tap
and a valve. This conduit is meant to cool the crown as well as the motor.
- Always use a water tap with a pressure not higher than 4 bar.
- Often check the integrity of the water hose.
For a correct use of the machine, the diamond segments are to be cooled when drilling and the holes should
be kept clean.
Make sure the water pressure and flowing is sufficient to cool the crown and clean the hole.
The diamonds segments could be damaged if there is not sufficient water even though they are used for a
short time.
You can know if the water flow is sufficient by observing the following:
-
If the water flowing out the hole is fluid, you are doing it right. .
-
If the water flowing out the hole is clay or if there is excessive dust, you should increase the refrigeration
volume.
-
If you have to enlarge a hole, you have to obstruct the anterior hole for a correct circulation of the water.
-
If you need to drill porous, fissured materials or materials that absorb big quantities of water, try to
reduce the leak of water throughout these materials and increase the water flow.
-
Carefully connect the water tube and avoid any leakage and hence loss of pressure.

DRILLING IN THE CEILING
When drilling in the ceiling, it is recommended to use a pneumatic or hydraulic motor. If an electrical motor is
used instead, a water collector should then be used to avoid water getting into the machine. Make sure the extension
cable is away from the water flow.
- We recommend using the water collector when drilling into walls and ceilings.
- To install the water collector, follow the manufacturer instruction manual.

FIXATION OF THE MACHINE
The correct anchorage of the drill is essential to ensure: security in the workplace, high-performance of the
drilling, quality in making holes, longer life of the engines and crowns. There are several ways of fixing the column,
observe and assess which is the most appropriate type of fixation.
Fixation system types:
Mechanical fixation with expansion rod:
this is the most used systems for floors and walls, by means of a
threaded asparagus. Proceed with the installation as follows:
-
Once fixed in the central drilling point, we define the bore of the metallic rod and we select the
adequate expansion rod according to the minimal indicated dimensions (M12).
-
We make a bore with the drill, and we introduce the metallic rod (minimal M12).
-
We place the rig and insert the asparagus through the slot on the basis fixing it through the washer
and its nut.
WARNING: The fixation by rod is inadequate when the material to drill does not have enough mechanical
strength to hold the rod, for example brickwork.
FIXATION WITH CONTRASTS (UNDERPINNINGS):
This is the most used system for its rapidity. There
are telescopic underpinnings specially manufactured for this end. Proceed with the installation as follows:
-
Place the drill unit in the defined point.
