▶
Remove the hand wheel when you are going to operate the drilling system with the auto-feed unit.
When the auto-feed unit is operating in automatic mode, the hand wheel tends to turn and can lead to
injuries or cause cables or hoses to become wrapped around it.
▶
Make sure that the power tool is correctly and securely mounted on the drill stand.
The auto-feed
unit has to be engaged at one of the keyed positions and it must be secured with the securing screw.
Additional safety instructions
▶
Make sure that the supply cord cannot be damaged as the carriage advances.
▶
On account of the drilling system's dead weight, as soon as the carriage lock is disengaged the
drilling system can glide down the drill stand without any braking effect by the installed auto-feed
unit.
Be prepared for this and hold the drilling system in place with one hand.
▶
If the drill stand has not been fastened correctly, always move the drilling system with installed
core bit all the way down in order to prevent the stand from falling over.
▶
Keep the supply cord, extension cord and water hoses away from rotating parts.
