Essential Maintenance Tips to Keep Your Assistive Technology Safe and Functional

Why Regular Maintenance Matters for Assistive Technology

Every day, Australians rely on power wheelchairs, mobility scooters, manual chairs, hoists and other assistive technology (AT) to stay active, independent and connected. When these devices are well-maintained, they perform reliably, stay safe and retain their value – crucial factors for NDIS participants who want to protect their funding and resale prospects.

This guide walks you through the essential care routines for each major AT category, highlights warning signs that call for professional help, and provides a handy safety checklist you can print and post next to your equipment.

Power Wheelchair Battery Maintenance

1. Adopt Smart Charging Habits

• Charge before the battery drops below 20%. Deep discharge shortens lithium-ion lifespan.
• Use the manufacturer-approved charger. Unmatched voltage can cause overheating.
• Avoid overnight "trickle" charging. Modern chargers stop automatically; a timed outlet prevents over-charging.
• Keep the charger in a cool, dry spot. Heat accelerates cell degradation.

2. Proper Storage for Infrequent Use

1. Store the wheelchair in a temperature-controlled room (15-25°C).
2. Charge the battery to about 50% before long-term storage.
3. Re-charge every 3–4 months to avoid deep-sleep mode.
4. Cover connections with a dust-proof cap to prevent corrosion.

3. Recognising When a Battery Needs Replacement

Typical lithium-ion packs last 2–4 years. Watch for these signs:

• Reduced range despite a full charge.
• Rapid voltage drop during use.
• Swollen or hot cells.
• Error codes on the control panel.

Tyre and Brake Checks for Power Wheelchairs and Mobility Scooters

Tyre Health

• Inspect tread depth weekly. Minimum legal tread is 1.6 mm; less can affect grip on wet surfaces.
• Check tyre pressure daily. Under-inflated tyres strain motors and reduce range.
• Look for cracks, sidewall bulges or embedded debris. Replace any tyre showing damage.

Brake Performance

1. Test the hand-brake or foot-brake by pulling while stationary; the wheel should lock firmly.
2. Listen for squealing or grinding – signs of worn pads or discs.
3. For electric brakes, verify the "hold" function on inclined surfaces.
4. Lubricate brake cables (if applicable) with a light silicone spray every 6 months.

Joystick and Electronics Care

Keeping Controls Clean

Dust, sweat and oils can corrode contacts, leading to erratic movement.

• Wipe the joystick with a lightly damp microfiber cloth weekly.
• Avoid harsh chemicals – use mild soap solution only if sticky residue appears.
• Cover the control panel when the wheelchair is not in use.

Protecting Wiring and Connectors

• Look for frayed cables, corrosion at connector pins and loose clamps.
• Secure any dangling wires with zip ties (avoid over-tightening).
• Secure the controller housing with the supplied screws after any service.

Manual Wheelchair Frame and Bearing Maintenance

Frame Inspection

• Check welds and joints for cracks or fatigue, especially after a fall.
• Ensure all bolts (e.g., axle, foot-rest, arm-rest) are tightened to manufacturer torque.
• Apply a thin coat of rust-inhibiting spray to aluminium or steel frames every 12 months.

Wheel Bearings

Bearings enable smooth rolling; neglect leads to wobble and increased effort.

1. Spin each wheel; any grinding or uneven resistance signals bearing wear.
2. Clean bearings with a brush and wash out old grease.
3. Re-grease with a high-temperature bearing grease; replace seals if cracked.
4. Re-assemble and test for free rotation.

Hoist Sling Inspection and Safety

Daily Visual Check

• Look for tears, cuts or worn edges on the fabric.
• Inspect metal rings and buckles for deformation or corrosion.
• Verify that all stitching is intact; loose threads can unravel under load.

Load Testing (Every 6 Months)

Secure the sling to a sturdy anchor and gently apply a test load (no more than 10% of its rated capacity). If the fabric stretches or the buckles slip, replace the sling immediately.

Annual Service Requirements

Even with diligent DIY care, certain components require specialised tools and calibration. An annual service typically includes:

• Comprehensive battery health assessment and firmware update.
• Full brake system bleed and adjustment.
• Electronic diagnostics for motor controllers and safety cut-offs.
• Frame alignment verification and bearing re-lube.
• Hoist load-capacity certification (if applicable).

DIY vs. When to Call a Technician

Tasks You Can Safely Do Yourself

• Battery charging routine and storage preparation.
• Tyre pressure checks and tread inspection.
• Cleaning joysticks, frames, and sling fabrics.
• Tightening loose bolts (using the correct torque rating).

When Professional Help Is Required

1. Battery replacement or any high-voltage work.
2. Brake system overhaul, hydraulic fluid changes or electronic brake calibration.
3. Motor or controller replacement, firmware updates, or fault-code diagnostics.
4. Bearing replacement involving press-fit components.
5. Any repair involving structural welds or load-bearing frame sections.

Protecting Your NDIS Funding and Resale Value

NDIS participants receive funding based on the principle of "value for money". Proper maintenance demonstrates responsible use, which can:

• Reduce the frequency of claim-based repairs, keeping more funds for upgrades.
• Provide clear service records that auditors view favourably.
• Maintain the device's market value – a well-kept wheelchair can retain up to 70% of its original price after 3 years.

Quick Safety Checklist

1. Charge battery to 100% before each long outing; avoid dropping below 20%.
2. Check tyre pressure and tread before every ride.
3. Test brakes on a level surface; listen for unusual sounds.
4. Wipe joystick and control panel; ensure no moisture.
5. Inspect manual wheelchair frame, bolts and bearings.
6. Examine hoist sling for tears, wear and correct buckle function.
7. Log any odd noises, reduced range or performance dips.
8. Schedule an annual professional service and keep the report.

Final Thoughts

Consistent, simple upkeep not only extends the life of your assistive technology but also safeguards your independence, complies with NDIS requirements and preserves resale value. By following the tips above, you'll enjoy smoother rides, fewer breakdowns and the confidence that your equipment remains as safe as the day you first trusted it.
