as possible.
- Turn sleeve (2) in direction "GRIP, ZU" until the
noticeable mechanical resistance has been over-
come.

turning the sleeve (it must "click" when turning)
until it cannot be turned any further - only now is
the tool securely clamped.

9 Tips and Tricks
Drilling
- Preferably in 2nd gear (high speed).
AUF, RELEASE
a
- Activate the pulse function (depending on the
model) to drill steel, aluminium or tiles without
centre punching or pre-drilling.
- Drill tiles and other brittle materials without
impact (depending on the model).
- In the case of deep bores, pull the drill bit out of
the bore from time to time in order to remove the
drill dust or swarf.
Screws
- Preferably in 1st gear (low speed) and with
torque control.
- Before inserting screws with deformed heads
into wood, activate the pulse function
(depending on the model).
- Activate the pulse function (depending on the
model) to reach the maximum torque while
inserting screws.
- The chuck can be removed for screwdriving.
Insert screwdriver bit directly in the hexagon
socket of the spindle. The screwdriver bit is
retained if a bit clamping bush (accessory, order
no. 6.31281) is fitted.
Thread tapping
