Otherwise the tool can be damaged.
WARNING!
m
Move the speed control switch away from
the chuck to position 1 for low speed (0 to
450rpm).
m
Use the low speed mode for screw driving
and for drilling holes with a large diameter.
m
Move the speed control forwards towards
the chuck to position 2 for high speed (0 to
1600 rpm).

holes.
The drill bit can jam in deep holes. Release
the power switch immediately if the drill bit
jams. Switch to anticlockwise rotation and
run the drill bit loose at low speed.
