Introduction
This manual provides essential information for the safe and effective use of your Cosydora R402KD Ultra Lightweight Foldable Rollator Walker. Designed for individuals seeking enhanced mobility and independence, this rollator features a reinforced aluminum frame, dual adjustable height settings, 8-inch all-terrain wheels, and a comfortable padded seat with a backrest. Please read these instructions thoroughly before assembly and first use to ensure proper function and user safety.
Setup
Unboxing and Initial Assembly
Carefully remove all components from the packaging. The rollator is designed for tool-free assembly. Ensure all parts are present and undamaged before proceeding.
Folding and Unfolding
To unfold the rollator, push down on the folding bracket located under the seat until the frame is fully extended and locked into place. To fold, lift the seat strap with one hand, allowing the rollator to collapse to a compact 9.5-inch width.

Attaching Wheels and Handles
The front and rear wheels are inserted into their corresponding numbered slots on the frame. Secure them using the provided triangular knobs. Similarly, insert the handtubes into the upper frame and tighten them with the triangular knobs. Ensure both handle tubes are set to the same height for balanced support.

Adjusting Height
The rollator features dual adjustable height for both the handles and the seat. Adjust the handle height (32.5"–38") to ensure a slight bend in your elbows when standing upright, promoting proper posture. Adjust the seat height (20"–22") so your feet rest flat on the ground when seated. Use the adjustment pins and knobs to secure your preferred height settings.

Figure 2: The rollator's handle height can be adjusted from 32.5 to 38 inches, and the seat height from 20 to 22 inches, accommodating users from 4'7" to 6'6".
Attaching Accessories
Attach the backrest by sliding it into the designated slots on the handle tubes. Ensure the 'Cosydora' logo faces the correct direction. The detachable under-seat storage bag can be secured with its straps, and the cup holder clips onto the frame.

Operating
Walking with the Rollator
Place your hands on the ergonomic hand grips. Push the rollator forward, maintaining a comfortable distance. The 8-inch all-terrain wheels with 360° swivel fronts provide smooth movement over various surfaces, including grass, gravel, and carpet.

Figure 4: The 8-inch PVC wheels are designed for all-terrain use, offering better stability and control over rough ground, with anti-vibration, silent movement, and non-slip properties.
Braking System
The rollator is equipped with a triple-mode braking system. To slow down, pull the brake levers upwards. To engage the parking brake (lock the wheels for sitting), push the brake levers downwards until they click into place. To release the parking brake, pull the levers upwards again.

Figure 5: The braking system allows users to pull the levers for resistance (safer for downhill) and push them down to lock the wheels, preventing movement when sitting.
Using the Seat
Before sitting, ensure the parking brakes are engaged and the rollator is stable. The extra-wide 13.8" x 12" padded seat and thickened, breathable backrest provide a comfortable resting station. The under-seat storage bag can hold up to 11 lbs of personal belongings.

Figure 6: The Cosydora rollator features a 120-degree breathable comfort backrest with airflow mesh, offering superior back support compared to basic designs.

Figure 7: The upgraded extra-comfort seat is 3cm thick, waterproof, and ergonomically designed for soft support, providing comfort for over 120 minutes of sitting.
Maintenance
Cleaning
Clean the rollator frame with a damp cloth and mild soap. Avoid abrasive cleaners. The padded seat and backrest can be wiped clean. The storage bag is detachable for easier cleaning.
Inspections
Regularly check all screws, knobs, and fasteners to ensure they are tight. Inspect the wheels for wear and tear, and ensure they rotate freely. Test the brakes periodically to confirm they engage and disengage properly. Check brake cables for any fraying or damage.

Troubleshooting
Wheels Not Rolling Smoothly
Check for debris or hair caught in the wheel axles. Clean as necessary. Ensure all wheel attachment knobs are securely tightened but not overtightened, which could restrict movement.
Brakes Not Engaging/Disengaging Properly
Inspect the brake cables for any kinks or damage. Ensure the brake pads are making proper contact with the wheels. Adjust the brake cable tension if needed (refer to Figure 8). If issues persist, contact customer support.
Rollator Feels Unstable
Verify that the rollator is fully unfolded and locked into place. Check that all height adjustment knobs for the handles and wheels are securely fastened. Ensure the handle and seat heights are set evenly on both sides.
