Further notes.
Use a cutting spray when working.
When the power supply is disconnected
while the motor is running or when the
switched-on power tool is plugged in, the
motor will not restart.
Carry out core-drilling processes without
interruption, if possible. To complete a
started and interrupted drilling run, repeat the
center-drilling process.
For stationary use in a drill stand, remove the
switched off power tool from the drill stand
at operating temperature every 50 operating
hours and turn it by 180° to achieve uniform
lubrication.
Replace dull centering drill bits; they may not
be reground.
After each drilling operation, remove the
chips and the slug.
Chippings and the core are
CAUTION
sharp and hot!
When changing a cutting tool, pay attention
not to damage the cutting edges.
When core drilling layered material, remove
the core and the chips after having drilled
through each layer.
