Maintenance
Before performing any maintenance, make sure the drill press and pump
are turned off.
Changing the Core Bit
1. Lower the core holding tray so that it is at least 6" below the tip of the
core bit.
2. Turn the core bit counter-clockwise to loosen it.
3. Pull the core bit straight down to remove it from the water swivel.
4. Place the new core bit into the water swivel and turn it clockwise to
tighten it in place.
Water Swivel Maintenance
1. Disconnect the pump from the flexible hose leading to the water swivel.
2. Loosen the chuck in the drill press and remove the water swivel.
3. Unscrew the screws on the side of the water swivel. This will open the
swivel body and give you access to the bearings and seals.
4. Remove both bearings and both seals.
5. Insert a new set of seals, then insert a new set of bearings.
6. Close the swivel body and tighten the screws.
7. Re-insert the swivel body into the drill press and tighten the chuck.
