Tool Head Cleaning: While the dual drive gears of the M175 extruder usually remain clean, you should inspect the drive gears from time
to time by turning the filament tension knob all the out (counterclockwise) and removing it from the quick release lever. The quick release
lever will open, exposing the dual drive hob gears. Use compressed air to clear any residual filament from the tool head and reassemble.
Reset the tool head tension as described in Section 5 of this Quick Start Guide after reassembly.
Check all fans on the tool head to ensure that they are functioning properly during printing. Note that the extrusion cooling fan on the
front of the tool head may not turn on while printing the first few layers on the print bed depending on the filament used. While the
printer is off, blow out all fans with compressed air to clear any build up of dust or debris.
The nozzle and heater block are coated to reduce the accumulation of filament. However, if
you notice an accumulation of filament on the nozzle and heater block, it can be cleaned by
heating the hot end up to 205°C (401°F) and then carefully wiping the affected areas using
the maroon Scotch-Brite ™ scrubbing pad from your TAZ Pro S tool kit.
Do not use metal to clean the nozzle
on your tool head. Metal will short the
self leveling function and can blow an
internal fuse or damage your printer.

HOT SURFACE BURN HAZARD. CONTACT MAY CAUSE BURN. DO NOT TOUCH THE HOT END.
The hot end on the extruder can quickly heat up beyond 180°C (356°F) and can burn your skin if you touch it.
