Date:1646374713

1, Put the collet into the nut, turn the collet slightly. Push it into the nut at the offered direction evenly when the offset flange sinks into the undercut of the collet. Push on the bottom of the collet until the collet completely enters, and lines up with the nut. As the collet moves into proper alignment, you will hear and feel a distinct click, indicating that the top of the collet is safely.

      2, Fix the nut and the collet on the spindle rotate the nut until the collet is in pressing, wipe the straight shank of cutter and insert it into the pilot hole. The nut / collet assembly can now be screwed onto the spindle, loaded with one of those great precise bits. Tighten the nut with a wrench till the cutter is clamped heavily and made ready to use. (Caution: never tighten the nut without cutter in it for it will break).

      3, When changing the cutter bits, remove the nut / collet from the spindle and remove any bits from the collet bore. Loosen the nut and it shall bring out the collet and the cutter together. And then draw the cutter out, push out slightly the collet in the offered direction, it shall be ready for any change of the cutters.
