Eibenstock END 1550 P Originalbetriebsanleitung Seite 24

Before drilling in supporting parts, make sure that you do not disregard
the statics. Observe the instructions of the experts who are responsible
for the design.
Make sure that you do not damage any gas mains, water mains or
electric cables while drilling.
Make sure that the drill bit is well fixed.
Only use tools which are suitable for the particular material.
For the END 1550 P we recommend the application of the centuring
device with water collection (order number 35836).
overhead the application of the water collection is compulsory.
Put the gas pressure spring together with the water collection ring and the
guide ring matching the diameter of the drill bit with the clamping clip on the
gearbox neck of the machine. Push the gas pressure spring until the
segments of the bit are covered by the water collection ring. Tighten the
wing screw in the clamping clip.
When drilling overhead, pay attention that you only open the water supply
after having switched on and attached the vacuum cleaner on the wall or
the ceiling.
Open the ball valve and switch the machine on. Hold the machine with both
hands.
While drilling, especially pay attention that the drill bit does not tilt.
Adapt the feed to the diameter of the drill bit and to the power of the
machine.
You have hit reinforced iron when you recognise while drilling that the feed
rate gets very low, when you need to use more force, or when the water
leaking from the bore hole clearly shows some metal chips. Reduce the
pressure on the drill bit to cut through the reinforced iron without any
problems. You can increase the pressure again when you have cut through
the reinforced iron.
If the drilling machine jams, do not try to solve this problem by switching on
and off the machine. Switch off the machine immediately and remove the
drill bit by turning left and right with a open-ended wrench. At the same
time, pull the machine carefully out of the bore hole.
Instruction for drilling without centering device with water collection:
Attach the machine with a small inclination. After the drill bit has penetrated
into the surface (about 1/8 – ¼ of the circumference), put the machine in a
90° angle and continue drilling.
