The drill chuck and taper shank are pre-installed on your milling machine. To replace the drill chuck with a collet
or end mill holder, follow the steps below for removing the drill chuck. Cover the table to protect it from getting
damaged, in case parts and bits are dropped onto the table.
1. Make sure the machine is unplugged to prevent accidental starting.

2. Remove the cylinder protective cover by pulling it upward (Fig. 3 - 1).
3. Insert the spindle lock rod into the hole on the right side to lock the
spindle. Using the M14 open end wrench, loosen the spindle drawbar a
few turns by turning it counterclockwise (as viewed from above). Do not
loosen it fully or remove it.
4. Hold the drill chuck gently with your hand. With the other hand, gently tap the top of the drawbar with a rub-
ber or plastic mallet to unseat the tapered shank in the spindle. Then remove the taper shank. NOTE: To protect
the table from getting damaged,
5. Wipe clean the taper shank and the inside of the spindle sleeve. Safety store the taper shank and drill chuck.
INSTALLING THE DRILL CHUCK TAPER SHANK/END MILL HOLDER
1. Make sure the machine is unplugged to prevent accidental starting.
3. Wipe clean the taper shank and inside of the spindle sleeve. The mating surfaces should be clean of any debris,
oil, or other detritus, as they can improperly orient the taper shank when tightening.
4. Insert the taper shank into the spindle sleeve.
5. With the cylinder protective cover (Fig. 3 - 1) removed, insert the spindle lock rod into the right side hole to
lock the spindle. Using the M14 open end wrench, tighten (clockwise) the spindle drawbar to fix the taper shank
in place. The drawbar should be snug in the spindle threads, but do not overtighten it.
6. Remove the spindle lock rod and reinstall the protective cover.
INSTALLING A DRILL BIT
1. Grab the drill chuck key and fully insert the tip into the hole on the chuck. Hold the bottom part of the chuck
stationary while rotating the chuck key counterclockwise to loosen.
2. Wear work gloves when handling drill bits to prevent injuries. Clean the shank of your drill bit and insert the it
into the drill chuck.
3. Insert the drill chuck key and rotate it clockwise to fully tighten.
NOTE: The above steps only applies for installing drill bits into the drill chuck. For installing end mills onto the
collet and end mill holder, follow the instructions included with your accessory.
