Before starting the working process
Before you start working, select the required speed. It is depending on the drilling diameter and
on the material used.
„Determining the cutting speed and the speed" on page 34
„Speed table B34H" on page 36,
WARNING!
For drilling jobs, it is necessary to clamp the workpiece firmly to prevent the bit catching
on the pieces. Example of suitable clamping devices include a machine vice or clamping
jaws.
Put a wooden or plastic board beneath the work-
piece to avoid drilling through to the work table,
vice, etc.
Use the drill depth stop when you want to have
several bore holes with the same depth.
When working with wood, make sure to use an
adequate dust extraction unit, as sawdust can
constitute a health hazard. Also use a suitable
protective mask for any work that generates dust.

During the working process
The spindle feed is being performed by the star grip. Make sure that the feed is being at a regu-
lar pace and not to fast.
The reset of the spindle is being performed by a track recoil spring.
WARNING!
Danger of clothing / or long hair getting caught.
•
Make sure to wear a well-fitting work suit during drilling work.
•
Do not use gloves.
•
If necessary, wear a hairnet.
CAUTION!
Danger of bumps by the levers on the star grip.
Do not release the star grip when repositioning the drilling spindle sleeve.
CAUTION!
Danger of crushing! Do not place your hand between the drill head and the spindle
sleeve.
The smaller the bit, the more likely it is to break.
In the case of deep drilling, remove the bit from time to time to remove drilling chips from the
bore hole. A few drops of oil will reduce friction and prolong the service life of the bit.
