Use the same 5 mm hex wrench and six screws to fix the tool holders to the
spindle disk (
3
). Then, select up to three tool bits suitable to planned use and place
them in the holders, with blades directed according to the rotation direction (
4
). Next,
use the 4 mm hex wrench and two of the screws (
5
) to tighten each tool bit. The whole
pressing surface of the screws must be in full contact with the tool bits.
3.2. Installing (removing) the mandrel and adjusting the clearance
Loosen the nut and use the 5 mm hex wrench to loosen the set screw (
1
, Fig. 3), and
insert the mandrel into the machine (
2
). Make sure that tool bits installed are not in
contact with the mandrel. Next, rotate the handles to the right (
3
) by at least 10 turns
until the mandrel engages with the machine fully. Then, tighten the set
screw
(
4
)
and
check whether the handles can be rotated in both directions easily.
If the screw is too
tight, readjust it. Finally, tighten the lock nut (
5
).
