3. Operating Instructions

The WaterRower M1 Hi Rise provides a full-body, low-impact workout. Follow these guidelines for effective operation:

3.1 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, palms down.
• The S4 Performance Monitor will activate automatically when you begin rowing or can be manually turned on.

3.2 Rowing Technique

Proper technique is crucial for maximizing workout effectiveness and preventing injury. The rowing stroke consists of four phases: the Catch, the Drive, the Finish, and the Recovery.

1. The Catch: Begin with knees bent, shins vertical, arms extended forward, and back straight.
2. The Drive: Push off with your legs, then swing your back, and finally pull with your arms. The handle should come towards your abdomen.

3. The Finish: Legs are extended, back is slightly reclined, and the handle is at your abdomen.

The S4 Monitor displays key metrics to help you track your progress:

• Stroke Rate: Strokes per minute.
• Intensity: Power output (e.g., watts, calories per hour).
• Time: Duration of your workout.
• Distance: Distance covered (e.g., meters, miles).
• Use the buttons on the monitor to navigate through different display modes, set workout programs, and view stored data.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your WaterRower M1 Hi Rise.

• Water Treatment: Add a water purification tablet to the tank every 3-6 months, or as needed, to prevent algae growth. Do not use harsh chemicals.
• Cleaning: Wipe down the frame and rails with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners.
• Rail and Wheel Inspection: Periodically check the seat wheels and rails for any debris or wear. Keep the rails clean for smooth seat movement.
• Strap and Cord Check: Inspect the foot straps and the pulling cord for any signs of fraying or damage. Replace if necessary.
• Storage: The WaterRower can be stored upright to save space. Ensure it is stable when in the upright position.
