After the desired depth is reached, insert the extractor into the bit "upside down"
i.e., with the edges turned down (
∩
), at a slight angle, applying upward pressure.
Push the extractor in the full length. Turn the handle a half turn backwards to break
the core loose from inside the tree. The edge of the extractor should now be
pointed upwards (
∪
). Remove the extractor from the bit by pulling the end cap. The
core sample should be in the extractor, held in place by the serrated tip.
Note!
If the wood is very hard, it is possible that the core does not break loose
properly. In this case, move the bit to another spot, start again, and when the
desired depth is reached, turn the handle one and a half turns backwards to make
sure the core breaks loose from inside the tree.
5. Remove the bit immediately from the tree. This should be done before analyzing
the core sample. If left in the tree, even for a short period of time, the bit might
become "locked" in the tree.
6. Clean the bit and extractor at the end of each day with light machine oil. Never
store a dirty or wet borer. It is recommended that beeswax be applied before each
use.
7. Put the plastic cap on the tip of the bit to protect the threads, and store the bit and
extractor inside the handle.
