Installation instruction
For ϕ 8 to ϕ 12 and drill hole depths ≤ 250 mm
or ϕ > 12 mm and drill hole depths ≤ 20 · ϕ.
Blow 2 times from the back of the hole (if needed with nozzle extension) over the
whole length with oil-free compressed air (min. 6 bar at 6 m³/h) until return air stream
is free of noticeable dust.
Safety tip:
Do not inhale concrete dust.
Brush 2 times with the specified brush (see Erreur ! Source du renvoi introuvable.)
by inserting the steel brush Hilti HIT-RB to the back of the hole (if needed with
extension) in a twisting motion and removing it.
The brush must produce natural resistance as it enters the drill hole
(brush Ø ≥ drill hole Ø) - if not the brush is too small and must be replaced with the
proper brush diameter.
Blow again 2 times from the back of the hole over the whole length with compressed
air until return air stream is free of noticeable dust.
