Setup, Compatibility & Care
To replace the cutting wheel, locate the pin securing the current wheel within the cutter head of your NT4023, NT4028, NT4035, or NT4067 model. Remove the pin, slide out the old wheel, and insert the replacement, ensuring the cutting edge faces the pipe stop. Reinsert the pin securely before use.
