flats on its head, and turn the sleeve (4) vigourously
in the direction of "AUF, OPEN".
8 Tips and Tricks
Only moderate pressure is required for hammer
drilling and chiselling. Applying a high degree of
pressure does not increase performance.
When drilling deep holes, remove the drill bit peri-
odically from the hole to remove dust.
Drill tiles and other brittle materials without impact.
9 Maintenance
Always keep the safety coupling (16) clean and
free from dust.
Always keep the spindle (6) clean and apply a light
coating of grease. (for information on special
grease, see Accessories section: order no.
