Clean and lubricate the chain with a teaspoon of Concept2 Chain Oil (a purified mineral oil), 20W motor oil, or 3-in-1 oil. Apply oil to a paper towel, and rub the paper towel along entire length of chain. Wipe off the excess. Repeat if needed.
Skewer Return Mechanism Information
Some Model A Ergometers came with a "skewer return mechanism" inside the monorail. All Model A machines with serial #84-8 to 85-66, or with serial #Nov. 4, 1985 and after have an improved return mechanism assembly already which is far easier to install than previous systems. This assembly is retrofittable to all Concept2 Model A Rowing Ergometers. No modifications are required to use the skewer in Model As with serial #83-13 and higher (these machines are easily identified by the black arms and feet, not chrome plated). For older machines, serial #83-12 and lower or no serial number at all, a modified leg bolt set is available at the cost of $1.40 (Part Number 343).
