If Nozzle is too tight, use the provided 7mm and 11mm flat wrenches for leverage. With the 11mm
flat wrench, hold the wrench flats on the bottom end of the heater block. Use the 7mm flat wrench
to loosen the nozzle, being careful not to apply any twisting force to the heater block. Carefully
loosen the nozzle until able to remove with your fingers.

If you need to replace the PTFE liner in a nozzle, proceed to step 4, otherwise skip to step 5.
If nozzle is too tight to remove by hand, proceed to step 3, otherwise skip step 3.
Applying twisting forces to the heater block may damage the heatsink of the hotend. Be sure to hold the heater block firmly
when removing nozzles with wrenches to avoid damaging the heatsink. Do not try to remove cold nozzles with filament still in
the hotend.
