This document is the Owner's Manual for the DKN H2Oar Rowing Machine, a high-quality, safe, and innovative piece of exercise equipment designed for indoor, home use. The manual provides essential information for assembly, operation, safety, maintenance, and exercise guidance.

Function Description

The DKN H2Oar Rowing Machine is designed to provide a full-body cardio-vascular workout. It simulates the action of rowing on water, offering a comprehensive exercise experience. The machine features a water tank system where the amount of water simulates the mass of an object being moved in water. Increasing the water level simulates a heavier load, while reducing it simulates a lighter load. The resistance is primarily altered by the user's rowing speed. The console provides real-time feedback on various workout metrics, helping users track their progress and achieve fitness goals.

- RESET: Clears last data entry; hold for 3 seconds to reset the display.
- ENTER: Confirms program selection or parameter settings.
- START/STOP: Starts, pauses, or stops a training session.
- UP/DOWN Arrows: Used to set values for time, calories, count, and distance, and for program selection.
Water Level Adjustment: The water level (L1-6) can be set using the console arrows, affecting the simulated mass moved during rowing.
Storage: The rowing machine can be stored vertically to save space. The manual illustrates how to fold and move the rower.

Maintenance Features

Regular Examination: The machine's safety level can only be maintained through regular examination for damage and wear, especially components like the pull cord, pedals, seat rail, and connection points.
Component Replacement: Stop using the machine immediately if defective components are found, and keep it out of use until components are replaced or repaired by a qualified engineer. Only use original spare parts; using 3rd party parts will invalidate the warranty.
Cleaning: DO NOT use aggressive cleaning products. Remove sweat drops immediately after training.
Water Tank Maintenance: Periodic maintenance of the water in the tank is required. Use provided water purification tablets every 6 months to prevent bacteria and algae growth. If water discoloration occurs, add a tablet immediately. If the water does not clear, empty, flush with clean water, refill, and add a purification tablet.
