Hilti HIT-DRS Dust removal system
3.2 Bore hole cleaning
• Check, if the dust removal system is safely connected to the vacuum cleaner.
• Switch-on vacuum cleaner.
• Check, if enough vacuum / air sucking flow is at the dust removal system.
• Place dust removal system over the bore hole to be cleaned and align its sealing disc
with bore hole centre.
• Insert cleaning tool (round steel brush, blow-out gun, tube with/without air nozzle)
through the dust removal system / sealing disc into the bore hole.
3.2.1 Blowing out
• Cleaning air flow should already be switched on when blow-out gun/ tube will be inser-
ted into the bore hole.
• Blow-out bore hole according to the conditions specified in the instruction for use /
operating instruction of the anchor which will be installed.
Note: At the end of cleaning no dust should be visible in the cleaning air coming out of
the bore hole.
Compressed air conditions:
- Cleaning air flow to bore hole:
- Compressed air pressure:
- Compressed air must be oil-free.
3.2.2 Brushing
Brush bore hole according to the conditions specified in the instruction for use / opera-
ting instruction of the anchor which will be installed.
Note: For round steel brushes above Ø 22mm / Ø 7/8" use the dust removal system
without sealing disc (no wear at brush and sealing disc, easier handling).
