As a user or caretaker of a Personal Mobility Aid (PMA), such as a motorized wheelchair or a mobility scooter, you hold the key to a person’s independence. These devices are more than just a means of transport; they are lifelines that enable freedom and mobility. Proper care and maintenance are crucial to ensure they remain reliable and safe.
Inspired by the common challenges faced by our customers at DrWheelchair, we have created this guide to empower you with the knowledge to keep your PMA in top condition. By paying attention to these key areas, you can prevent unexpected breakdowns and costly repairs, ensuring a consistently smooth and safe ride.
1. The Heart of the PMA: Battery Care and Management
The battery is the single most important component of any motorized wheelchair or mobility scooter. Its health directly impacts the device’s performance, range, and longevity.
Daily Habits to Adopt:
- Charge when low battery: Make it a habit to plug in the PMA when the battery level is low. This practice prevents the battery from getting a “deep discharge,” which can permanently shorten its lifespan.
- Follow the Manufacturer’s Instructions: Different battery types (Sealed Lead Acid, Gel, or Lithium-ion) have specific charging requirements. Always use the charger that came with the device and follow the recommended charging times outlined in the user manual. Avoid leaving it plugged in for extended periods after it is fully charged.
- Avoid Draining to Zero: Never let the battery completely drain to empty. This can cause significant damage and may prevent the battery from being able to hold a charge again. It’s best to recharge when the battery indicator shows it is low.
Warning Signs of a Failing Battery:
- Reduced Range: The device cannot travel as far as it used to on a full charge.
- Inconsistent Performance: The motor sputters, struggles on inclines, or the lights dim when the user attempts to accelerate.
- Shorter Charging Time: The battery takes noticeably shorter to reach a full charge.
- Visible Damage: Look for a swollen or bulging battery case, or a white/greenish powdery substance (corrosion) on the terminals. These are serious safety hazards and require immediate professional attention.
2. The Foundation: Tyres and Wheels
Properly maintained tyres ensure a smooth ride, stability, and optimal battery performance.
- Check Tyre Pressure (for pneumatic tyres): Just like a car, tyres with incorrect pressure can impact handling and cause the motor to work harder, draining the battery faster. Check the manufacturer’s recommended pressure and use a simple gauge to ensure they are properly inflated. If you are using HSA compliant PMA then there is no concern because they are solid tyres.
- Inspect for Wear and Tear: Regularly check the tyres for cracks, punctures, or signs of uneven wear. If the treads are worn down, it’s time for a replacement. For solid tyres, check for any significant damage or cracks.
3. The Body and Structure: A Safety Check
A quick visual inspection can prevent major issues down the road.
- Cleanliness: Keep the device clean from dirt, dust, and debris. Use a dry cloth to wipe down the body and the control panel. Avoid using a hose or power washer, as this can damage the electrical components.
- Inspect for Loose Parts: Check all nuts, bolts, and screws to ensure they are secure. A loose part can lead to a safety hazard or cause damage to other components. Pay special attention to the armrests, footrests, and seat.
- Check Electrical Connections: Ensure all wires and connectors are securely in place and free from fraying or damage.
4. The Brains of the Operation: The Controls
The joystick or control panel is the user’s primary interface with the PMA.
- Test for Responsiveness: Make sure the controls respond smoothly and predictably. If the device pulls to one side or has a delay in response, it may need recalibration or repair.
- Keep it Dry: The control panel contains sensitive electronics. Protect it from rain or spills with a cover, and always dry it thoroughly if it gets wet.
5. When to Call the Experts
While regular at-home maintenance is vital, some issues require a professional touch.
- Strange Noises or Odors: If you hear unusual grinding sounds from the motor or detect a burning smell, stop using the device immediately and contact DrWheelchair.
- Error Codes: If the display panel shows a warning or error code, consult the user manual. If the problem persists, it indicates a deeper issue that needs a diagnostic check.
- Annual Servicing: We highly recommend a professional service check at least twice a year. A trained technician can perform a thorough inspection, test the battery, and ensure all components are functioning safely and efficiently. Book an appointment with DrWheelchair.
By following this checklist, you can play an active role in maintaining the reliability and safety of your PMA.
