Step 8: Turn on the printer and pre-heat hotend to 280°C (Read Part 2 if you have current hotend cannot heat above 260°C) [Do note: if you using larger adjustable wrench you may need to wait until temperature to equalised, you may need to perform a PID if you having issues reaching these higher temperature.]
The hotend is now at 280 degrees celsius.
Be extremely careful not to burn your fingers when tightening the
nozzle and the grub screws
Step 9: Using a provided spanner and adjustable wrench tightening the unit as shown in below photo, one holding the heatbreak in-place and one on the nozzle.
