NOTE
►
If possible, always select a setting
with low gear stage and high motor
speed. The motor is then set with a
higher torque and therefore protect-
ed against overheating under heavy
load.
Drilling with the machine
Drilling with twist drills
When drilling with twist drills, proceed as
follows:
Insert the twist drill from below into the
tool holder (2) of the machine.
Position and fix the machine at the
location of use.
Switch on the clamping magnet and
check the magnetic holding force (see
section
“Activating/deactivating the
magnetic clamp”
).
Select a suitable speed and switch on
the machine.
Direct the drill to the material with the
handle (9).
NOTE
Observe the following instructions when
drilling with twist drills:
►
Under excessive pressure, the drill
can wear out and the machine can be
overloaded.
►
In overhead operations, use the
high-performance ZHS 400 grease
spray. Spray the drill before taking on
drilling. Spray the drill on the inside
and outside before drilling. In the
case of larger drill depths, repeat this
procedure.
►
Make sure that swarf is removed
regularly. With larger drilling depths,
break up the swarf.
