Manually move the X-axis assembly all the way to the front side of the printer.
Move the extruder approximately to the center of the X-axis.
If you have loaded the filament, unload it from the hotend. On the screen, navigate to Filament -> Unload Filament.
WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!
Remove the filament from the hotend. It is not necessary to completely remove it from the printer. Just a few centimeters (inches) above the extruder.

WARNING: The hotend and heatbed are very HOT. Do not touch these parts!!!
For the following steps, it is necessary to have the heaterblock and the hotend clean from the remains of the filament. Otherwise, it can be difficult to release the nozzle.
If you have a Prusa hotend sock on the hotend, remove it.
On the printer screen, go to Preheat and select the latest used material. (e.g. ABS)
Wait at least 5 minutes. The remains of the filament must be warmed up slightly so that they can be removed more easily.
Using the brass brush, carefully clean the heaterblock and the hotend from the filament residue. Avoid contact of the brush with the hotend cables, as this could cause a short circuit.
When the heaterblock and the hotend are perfectly clean, cool down the printer. On the screen, navigate to Preheat -> Cooldown.
Wait until the hot parts are cooled down to ambient temperature. It takes approximately 10 minutes.

Before you proceed, it is recommended to protect the heatbed.
Make sure the heatbed is cooled down to ambient temperature. Place the empty cardboard box approximately to the front center part of the heatbed.
From the rear side of the printer, turn the power switch OFF (symbol "O").
Unplug the PSU cable.

Step 6 Disconnecting the hotend

Using your left hand, insert the Torx TX 8 key all the way through the X-carriage until it reaches the grub screw in the extruder. Loosen the screw. Do not remove the screw, a few turns are enough!
Carefully pull the hotend assembly out of the extruder.
At the same time push the hotend cables behind the fan out of the extruder.

In the following steps, we will need to heat up the nozzle. Avoid touching the HOT parts on the hotend.
Remove the cardboard box from the heatbed!
Plug the power cord to the printer and turn it ON.
Now, you will need to set the nozzle temperature to 255°C. On the printer screen, navigate to Preheat-> ABS.
WARNING: From now, the hotend and heatbed are very HOT. Do not touch these parts!!!
Grasp the heaterblock with the wrench 13-16. Avoid pulling on the hotend!
Tighten the nozzle using the universal wrench. Do not overtighten it, you can damage the thread. Use the sufficient force. The prescribed tightening torque is 1.5 Nm.
NOTE: Avoid bending the hotend assembly while tightening! After that, there will be a gap of approximately 1 mm between the nozzle and the heater block.

Make sure, the hotend is cooled down. Push the hotend assembly all the way in.
Rotate the heaterblock as in the picture. There must be approximately 35° - 40° angle to avoid damaging the hotend cables.
Maintain the position and using the TX 8 Torx key tighten the grub screw to secure the hotend. Do not use extra force while tightening, it may damage the hotend nub.
