Rest the brace against the upper end of the column, extending it up to the ceiling and tighten it
through the upper contrast of the column.
IMPORTANT: NEVER TRUST THE ANCHOR OF ITS EQUIPMENT ON ITS OWN WEIGHT, PLUS THE
WEIGHT OF THE OPERATOR STANDING ON IT. THE RISK IS VERY HIGH TO CAUSE SERIOUS ACCIDENTS.
The risk is very high. There might be excessive vibrations that would adversely affect: the machine, the speed
of drilling and the performance of the diamond crown.
With any unexpected blockade of the crown, the possibility to increase the risk to lose segments is big. Worse
even is an accident of the OPERATOR (in the revolving transition that produces the drilling basis).
FIXATION WITH THE VACUUM PUMP:
Vacuum pump fixation is fast and cost effective. The surface must be smooth to avoid air leakage. The
surface should also be compact to avoid the separation of the top layer. In case the surface is rough or irregular, it
must be levelled until it is adequate.
WARNING: When carrying out works on walls and ceilings, the vacuum pump system is not enough and
should be combined with contrasts or underpinnings to prevent any fall of the equipment in case of anomalies in the
vacuum production system.
The vacuum pump system is not recommended for drilling diameters superior to 250 mm.
Proceed with the installation as follows:
1.
Remove the four screws of the rig.
2.
Place the air tightness rubber band in the rig.
3.
Install the pressure gauge in the slot of the rig.
4.
Connect the hose to the vacuum pump.
5.
Add some oil to the pump, switch it on, Wait to reach the pressure and the pointer is in the green area of
pressure gauge of the pump.
6.
Connect the hose of the pump with the pressure gauge.
7.
7. Once the system is connected and the pump is on and the air starts to be drawn in, the column is then
fixed.
Always work with the pointer into the green area of the manometer, the minimum pressure is 0.8
bars. Working below this pressure can cause accidents.
FIXATION WITH A COMBINED SYSTEM: When the system of anchorage, either with rods or with vacuum
pump, seems not to guarantee a safe fixation with drillings over 250mm, you should use a complementary fixation
with contrasts or underpinnings.
INTERRUPTING THE DRILLING: If the rig fixation is loosened and the drilling unit needs to be placed back,
you should centre very well the crown. Otherwise, this would provoke a strong dragging of the latter. If it not possible
to centre the crown, make a bore of 15 or 20mm diameter.
BLOCKS: In case of drilling in blocks that are not entirely part of a building, avoid that these move or be
uprooted.
7. HOW TO USE THE DRILL
7.1 PRELIMINARY CHECKUPS
WARNING: Before drilling a reinforced concrete structure, make sure not to drill in vital zones and not
damage the structure; Do it the way the project manager has recommended.
Do not damage the gas en water conduits in the working area.
When drilling walls where possible electrical cables are to be found, do not touch the metallic parts of the
machine. Use non-conducting materials and gloves to avoid any electrical charges
