To change the drill chuck on the BOSCH GSB 16 RE Professional Impact Drill, follow these steps:
1. Pull the plug out of the socket before carrying out any work on the power tool.
2. If your power tool does not have a drill spindle locking mechanism, you must have the drill chuck changed by an authorized after-sales service center for Bosch power tools.
3. Removing the Drill Chuck:
a) Remove the auxiliary handle.
b) Insert a steel pin with a diameter of 4 mm and a length of approximately 50 mm into the hole on the spindle collar to lock the drill spindle in place.
c) Clamp a hex key in the keyless chuck, leading with the short shaft.
d) Place the power tool on a firm surface, such as a workbench. Hold the power tool in place and loosen the keyless chuck by turning the hex key in the rotational direction. A tightly seated keyless chuck is loosened with a light blow on the long shaft of the hex key. Remove the hex key from the keyless chuck and completely unscrew the keyless chuck from the power tool.
4. Fitting the Drill Chuck:
a) To fit the keyless chuck, perform the same steps in reverse order.
b) The drill chuck must be tightened using a tightening torque of approximately 30-35 Nm.
Please refer to the "Changing the drill chuck" section in the instruction manual for more detailed instructions and illustrations.
