The SV08 ships from Sovol with a 0.4 mm nozzle already installed. Like any nozzle, it will eventually clog, wear down from abrasive filament, or just need swapping for a different size. The SV08 is a Voron V2.4 derivative, so the hotend rides on the flying gantry at the top of the machine, and the design keeps routine nozzle work quick: the plastic cover over the hotend attaches magnetically instead of with screws, and it lifts straight off without reaching for a tool.
With the cover off, you’re looking at the nozzle mounting plate, a piece of sheet metal that actually holds the nozzle assembly in place. Three M3x12 screws secure it, and those are the fasteners you loosen to free the old nozzle and retighten once the new one is seated. Sovol doesn’t publish a torque spec for these, so treat “snug” as the target rather than cranking them down hard against a heated aluminum plate.
Sovol has a video on its wiki titled “SV08 Nozzle Cleaning and Replacement Tutorial” that covers both jobs together. Worth watching once before you open the cover yourself, since cleaning and replacement share most of the same steps right up until the point you actually pull the old nozzle out.
Search interest in this exact procedure is still small, about 10 searches a month in the US, though it’s climbing fast, up 100 percent year over year, as more SV08 units get into use and start needing this kind of upkeep. A nearby term, “sovol sv08 nozzle,” pulls roughly double that volume, but most of that traffic is people shopping for a replacement part rather than looking for instructions. This guide sticks to the swap procedure itself, not nozzle sizing or where to buy one.
The cover comes off without tools, so it’s worth popping it open just to look even when you’re not ready to swap yet, whenever you want to check the nozzle for wear or a partial clog before committing to a full replacement. Once everything’s back together, check that all three screws are evenly snug: that keeps the nozzle seated flush against the heater block, which matters more for print quality than how tight any single screw is.
A worn nozzle is one of the few SV08 parts that wears out on a predictable schedule; the SV08 maintenance schedule covers the belts, firmware and other checks that apply here too. For general context on how nozzle condition affects a print’s first layer, see the first-layer troubleshooting guide.
