extension cord if it is damaged while working. Disconnect the supply cord plug from the power
outlet. Damaged supply cords or extension cords present a risk of electric shock.
▶ Never operate the machine when it is dirty or wet. Dust, especially dust from conductive materials,
or dampness on the surface of the power tool can, under unfavorable conditions, lead to electric shock.
Have dirtied or dusty power tools checked at regular intervals by Hilti Service, especially if they are used
frequently for working on conductive materials.
▶ Whenever you operate the diamond core drilling machine without DD AF-CA H, always install the
cover over the AC supply for the DD AF-CA H. Water entering the power tool will increase the risk of
electric shock.
Workplace
▶ 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 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.
