Clean the dust shield on the chuck at regular intervals
using a clean, dry cloth. Carefully wipe the sealing lip
and grease it with a little Hilti grease. It is essential that
the dust shield is replaced when the sealing lip is dam-
aged. Proceed as follows: Insert a screwdriver at the
edge of the dust shield and lift it out in a forwards direc-
tion. Clean the contact surface and insert a new dust
shield. Press it in firmly until it engages.
Also take care of your insert tools. Clean off dirt and dust
deposits and protect your insert tools from corrosion
by wiping them from time to time with an oil-soaked rag.
Always keep the connection end clean and lightly greased.
