9. Tips and Tricks

Drilling
- Preferably in 2nd gear (high speed).
- 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 drill chuck can be removed for screwdriving.
Insert the bit directly in the hexagon socket on the
spindle.
With the BS 14.4 LT Quick and BS 18 LT Quick,
the screwdriver bit is held in place by a magnet.
Use the clamping bush for other tools. (The
screwdriver bit is retained if a bit clamping bush
(accessory, order no. 6.31281) is fitted. )
Thread tapping
- Lubricate the dies.
- Select 1st gear (low speed).
- Adjust torque control.
