Hydrow is very low maintenance. As long as the machine is being operated indoors in 32°F to 104°F and stored in -4°F to 140°F, and the screen is not in direct sunlight, no maintenance of the internal components should be needed. The only real maintenance is keeping the track clean from debris.
CAUTION: Keep hands away from moving parts. Do not insert objects into openings in the Hydrow. Read all safety information and instructions in the Hydrow Manual before assembly and use. Failure to do so could result in injury. Do not store Hydrow upright without the Hydrow storage kit.
