Unfolding the Rowing Machine
The machine is designed with a tri-fold mechanism for compact storage. To unfold it for use:
- Locate the folded rowing machine. It occupies approximately 3.23 ft² (28.94" x 18.9" x 22.83") when folded.

Filling the Water Tank
The water tank provides the resistance for your workout. Refer to the markings on the tank for recommended water levels. Use distilled water to prevent mineral buildup.
- Remove the rubber stopper from the top of the water tank.
- Using the provided siphon pump, fill the tank with water to your desired resistance level. The machine offers 6 levels of adjustable water resistance.
- Replace the rubber stopper firmly to prevent leaks.

Operating Instructions
Getting Started
- Sit on the seat and place your feet securely in the foot straps. Adjust the straps for a snug fit.
- Grasp the handle with both hands, ensuring a firm but comfortable grip.
- Begin rowing with a smooth, controlled motion. The rowing stroke consists of three phases: the catch, the drive, and the finish.
Proper Rowing Technique
- The Catch: Start with your knees bent, shins vertical, and arms extended forward. Your back should be straight, leaning slightly forward from the hips.
- The Drive: Push off with your legs, then swing your back, and finally pull with your arms. Your legs should do most of the work.
- The Finish: Your legs should be fully extended, back leaning slightly back, and handle pulled to your abdomen.
- The Recovery: Extend your arms forward, then pivot your hips forward, and finally bend your knees to slide the seat back to the catch position.

- Speed: Your current rowing speed.

Maintenance and Care
Regular maintenance ensures the longevity and optimal performance of your rowing machine.
- Cleaning: Wipe down the machine with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners.
- Water Tank: Periodically check the water level and quality. If the water becomes discolored, replace it with fresh distilled water. A water purification tablet can be added to prevent algae growth (not included).
- Rail and Wheels: Keep the rail clean and free of debris to ensure smooth seat movement. Inspect the seat wheels for wear.
- Straps and Connections: Regularly check foot straps, handle connections, and all bolts and screws for tightness. Tighten as necessary.
- Storage: When not in use, fold the machine into its compact state and store it in a dry, cool place away from direct sunlight.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on monitor | Batteries are dead or incorrectly installed. | Replace batteries or ensure they are installed correctly. The monitor is battery powered. |
| Rough or noisy seat movement | Rail is dirty or seat wheels are worn. | Clean the rail with a damp cloth. Inspect seat wheels for damage and contact support if replacement is needed. |
| Resistance feels too low/high | Water level in the tank is incorrect. | Adjust the water level in the tank using the siphon pump. More water increases resistance, less water decreases it. |
| App not connecting to machine | Bluetooth is off, app not updated, or machine not discoverable. | Ensure Bluetooth is enabled on your device. Update the app to the latest version. Restart the rowing machine's monitor. |
