How to use:

• The nozzle you want to clean should be heated to the recommended printing temperature.
• As directed by the manufacturer of your printer, unload any existing filament.
• The heated nozzle should be gently removed from the heat block while it is still at printing temperature.
• With caution not to enlarge the nozzle hole, carefully insert the drill bit into the nozzle by hand, working from the inside out (following the filament's course).
• Re-heat the heat block to operating temperature after clearing any obstructions, then refit the nozzle (avoid overtightening).
• Before printing, level your print bed again.

Remember these usage tips:

• A 3D printer's nozzle should never be taken out of the machine before it has reached its maximum operational temperature.
• The drill bit should not be fastened to any power instrument.
• Because the drill bits are comprised of hardened tungsten alloy, use caution when applying excessive force.
• To remove built-up plastic, immerse the cooled drill bit in a solvent after usage.
