2.2. Installing and removing the arbor, twist drill bit, or screw tap chuck
Unplug the machine from the air source, and then rotate the spoke handles to the right (1, Fig. 3)
to raise the motor. Use a clean and dry cloth to wipe the spindle and arbor (twist drill bit, screw
tap chuck with axial compensation). Next, wear protective gloves and insert the arbor (drill bit, tap
chuck) into the spindle (2). Make sure that the vertical rod is not located between the hose fitting
and the horizontal rod (3).
To remove the arbor (drill bit, tap chuck), raise the motor, and then rotate the spindle (1,
Fig. 4) in such a way to align the openings in the spindle and gearbox (2). Next, insert the
MT3 drift (3) into the opening, and tap the drift using a mallet (4).
