5. Operating Instructions
5.1. Resistance Adjustment
Your rowing machine features 12 levels of hydraulic resistance. To adjust the resistance, locate the knob on the hydraulic cylinder. Turn the knob clockwise to increase resistance (making it harder to pull) and counter-clockwise to decrease resistance (making it easier). Start with a lower resistance and gradually increase as your fitness improves.
