▶ If the drill stand has not been fastened correctly, always move the machine mounted on the drill
stand all the way down in order to prevent the stand from falling over.
▶ Keep the supply cord, extension cord, water hose and vacuum hose away from rotating parts of
the machine.
▶ Use of the water collection system in conjunction with a wet-type industrial vacuum extractor is a
mandatory requirement for wet drilling overhead.
▶ Use of the vacuum securing method without an additional means of fastening is prohibited for
drilling in an upward direction.
▶ An additional means of securing the drill stand must be employed when the machine is secured
with the vacuum securing method (accessory) for horizontal drilling.
