Installing or Removing the Core Bit
Caution! Always be sure that the machine is switched OFF and unplugged before installing or removing the bit. Clean the core bit
before installation. Apply a light coat of grease to the core bit thread. (This can make the bit be easier to remove after operation.)
Screw the selected core bit onto the drive spindle. Make sure that the threads of the core bit and the drive spindle are matching.
Otherwise, use a suitable adapter.
Run the machine at an idle after tightening the core bit to check the running vibration of the core bit. To remove the bit, use a
wrench to hold the drive spindle and a wrench to loosen the core bit. Always unscrew the core bit from the drive unit when the
drilling task is finished. With wet-drilling operations in particular, there is also a danger of the core bit becoming corroded, making
it difficult to remove
Caution:
Wear protective gloves when replacing/removing the core bit. The core bit can become hot after prolonged operation of the
machine.
Switch Operation
This machine is equipped with a fault-current safety switch. To start the machine, simply pull the switch lever up to the “ON"
position and pull it to the "OFF" position to stop the machine
The fault-current safety switch will automatically break off when overcurrent occurs. Should this be happened, switch off the
machine and restart it about three minutes later to let the switch cool down.
Installing the Water Collector
Mount the two retainers to the base by loosening the adjustment screws and let the retainers press on the water collector Tighten
the adjustment screws so that the water collector will be pressed against the surface to be drilled. And then connect the hose to d
rain outlet so drain water will come out through the outlet.
Caution:
Overhead drilling without water collector is forbidden.
