Switching on the coolant pump (Fig. 12).
When working overhead or on
vertical surfaces, the coolant
container must not be used. Use a coolant
spray instead.
Liquids penetrating your elec-
tric power tool may cause electric shock.
Do not use the magnetic core drill unit
when the cooling-lubricant system is
defective. Check for tightness against leaks
and for cracks in the hoses. Prevent liquids
from entering or penetrating electrical com-
ponents.
➤
To activate the cooling lubricant flow,
press the button with the „
“ symbol.
The LED in this button lights up.
Actuating the button for clockwise or
anticlockwise rotation starts the pump.
➤
To end the cooling lubricant flow,

again. The LED goes out.
Switching the gear setting.
With the gear switch, you can select the
speed and thus the torque.
Adjust the gear setting only when the
machine is at a complete stop or when the
motor is running down.
➤
Set the switch to gear 1 to work at low
speed with high torque. This setting is
suitable for drilling with large drill bit dia-
meters and for tapping.
➤
Set the switch to gear 2 to work at
medium speed and medium torque.
➤
Set the switch to gear 3 to work at high
speed and low torque. This setting is sui-
table for drilling with small drill bit diame-
ters.
