ASSEMBLY & ADJUSTMENTS
REMOVING THE DRILL CHUCK
The drill chuck and taper shank are pre-installed on your milling ma-
chine. To replace the drill chuck with a collet or end mill holder, follow
the steps below for removing the drill chuck. Cover the table with a
spare towel or rag to protect it from getting damaged, in case parts
or bits are dropped onto the table.
1. Make sure the machine is unplugged to prevent accidental starting.
2. Remove 3 cap hex screws securing drawbar cap (Fig. 4 - 1) to the
headstock.
3. Secure the spindle (Fig. 5 - 1) from the bottom with the spindle
wrench and loosen the drawbar from the top by using the 8 mm hex
wrench and turning the drawbar only one full turn counter clockwise.
NOTE:
Do not completely unscrew the drawbar from the spindle. Do-
ing so before the next step of striking it with a hammer can poten-
tially damage the threads on both the drawbar and the arbor.
4. Tap the top of the drawbar with a dead-blow or brass-head ham-
mer to release the taper of the drill chuck.
5. Hold onto the drill chuck while fully unthreading the drawbar. Once
the drawbar is unthreaded, carefully remove the drill chuck from the
spindle.
INSTALLING DRILL CHUCK / COLLET / END MILL HOLDER
1. Make sure the machine is unplugged to prevent accidental starting.
2. Align the keyway of the chuck/collet with the pin inside the spindle
taper. Firmly press the chuck/collet into the spindle taper to seat it.
3. Hold the chuck/collet in the spindle and insert the drawbar into
the spindle from the top. Thread the spindle into the chuck/collet and
hand-tighten tighten the drawbar.

in the spindle to tighten the drawbar securely.
