*Preferably to clean the dust before installing.
Hit the drop-in anchor inside with a hammer.
Fix the rod to the drop-in anchor.
Place the core drill stand to the rod.
* The 4 screws at the 4 corners of the base rig are for levelling purpose,do not remove it for anchoring purposes.
After placing onto the rod, lock it with a washer and
a nut. Make sure it is stable at its position.
Place core drill motor to the core drill rig.
Put on diamond core bit. Make sure is locked well.
If position not right, adjust it until you get the right position. Then, lock the anchoring well.
You are all ready to do the coring! If you are using dry coring, ensure you have a vacuum set up directly to the machine for a cleaner coring. Works the same for wet coring.
