Purchase a spare belt...keep it in a sealed zip lock bag and out of the sun (UV rays are bad for rubber). According to the "Needle Doctor" (who I asked this exact question) the belt can last up to five years or as little as six months. Go figure. I am going to change the belt every two years just for good measure. If you have the 'new' dc drive motor, no maint. is required for its design life.
