▶ Approval must be obtained from the site engineer or architect prior to beginning drilling work.
Drilling work on buildings and other structures may influence the static equilibrium of the structure,
especially when steel reinforcing bars or load-bearing components are cut through.
▶ 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 cleaner 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.
