4.3 Adjusting Foot Straps
Adjust the foot straps to comfortably secure your feet to the footplates. Your feet should be firm but not overly tight, allowing for a full range of motion during your stroke.
5. Operating Instructions
5.1 Understanding Water Resistance
The KINGSMITH WR20 uses water resistance, which naturally adjusts to your effort. The harder you pull, the more resistance you will feel, mimicking the feel of rowing on water. The 6-level adjustable water tank allows you to fine-tune the base resistance by changing the water volume.
5.2 Using the LCD Monitor
The built-in LCD monitor provides real-time feedback on your workout. It typically displays:
- TIME: Duration of your workout.
- DIST: Distance rowed.
- CAL: Calories burned.
- STROKES: Total number of strokes.
- SPM (Strokes Per Minute): Your current stroke rate.
- SPEED: Your current speed.

Enhance your training by connecting your WR20 to the Kinomap and KS Fit applications via Bluetooth. These apps allow you to:
- Track and save your workout data over time.
- Access guided workouts and virtual rowing routes.

- Optimize your training based on detailed progress reports.

5.4 Proper Rowing Technique
A proper rowing stroke involves four phases: the Catch, the Drive, the Finish, and the Recovery. Focus on smooth, controlled movements to maximize effectiveness and minimize injury risk.
- Catch: Knees bent, shins vertical, arms extended forward, back straight, core engaged.
- Drive: Push off with legs, then swing back with your torso, and finally pull the handle towards your abdomen with your arms.
- Finish: Legs extended, torso slightly reclined, handle at abdomen, elbows past the body.
- Recovery: Extend arms forward, then pivot torso forward, and finally bend knees to slide forward to the catch position.

- Cleaning: Wipe down the machine with a damp cloth after each use to remove sweat and dust. Avoid abrasive cleaners.
- Water Treatment: If using water treatment tablets, add one every 6-12 months, or as needed, to prevent algae growth in the water tank. If the water becomes cloudy, empty and refill the tank with fresh water and a new tablet.
