Q: How do I adjust the belt spring tension on a TUNTURI R35 rowing machine?

The TUNTURI R35 rowing machine is equipped with a magnetic resistance system with a simple transmission belt that does not require specific spring tension adjustment during normal use. Unlike air or water resistance rowers, the magnetic system of the R35 is a self-regulating mechanism that requires minimal maintenance. The resistance mechanism tension is fully regulated via the resistance adjustment knob located at the top of the support frame. Turn the knob clockwise (+) to increase resistance, or counterclockwise (-) to decrease it. The graduated scale from 1 to 8 above the knob allows you to easily select the desired level. To prolong the lifespan of your rowing machine and the resistance mechanism, always set the knob to level 1 after each training session . This practice recommended by Tunturi minimizes tension on the resistance mechanism when the device is not in use. Regarding general maintenance: regularly check that all screws and nuts are tight , especially those on the rails and support frame. Clean your rowing machine with a damp cloth after use. Do not use solvents. The inner surfaces of the rails can be cleaned if necessary, and you can lightly apply paraffin to improve the smoothness of the seat movement. Important: never remove the device's protections. The TUNTURI R35 requires only minimal maintenance. If you observe a malfunction or abnormal noise during use, immediately contact an authorized Tunturi dealer with your rowing machine's serial number.
