How to Maintain a 7000-Series Aluminum Wheelchair

In our previous article—Inside a High-End Aluminum Wheelchair Factory: What Only Top Factories Know—we explained the differences between 7000-series and 6000-series aluminum wheelchairs. The response was overwhelmingly positive, and many distributors and buyers from around the world reached out to ask a follow-up question:

"How should I properly maintain a wheelchair, especially a high-end 7000-series aluminum model?"

Because 7000-series aluminum wheelchairs offer superior strength and performance, customers naturally want to know whether they require special care. To answer these questions clearly and professionally, we prepared this guide—covering the exact maintenance routines, differences between materials, and recommended service intervals to keep your wheelchair in optimal condition for years.

Key Conclusion

The core maintenance principles for 7000-series and 6000-series aluminum wheelchairs are the same (moisture protection, corrosion prevention, impact avoidance). Due to differences in alloy composition, there are small but important differences in corrosion resistance and structural checks:

• 7000 series → more attention to avoiding hard impacts

• 6000 series → stronger focus on rust prevention

Maintenance Differences

7000-Series Aluminum Alloy

• Impact Protection

7000 series has lower toughness than the 6000 series. Avoid hitting hard edges (steps, door frames) to prevent cracks.

Note: High-strength alloys develop cracks that can spread and affect structural safety.

• Corrosion Prevention

After exposure to salt (seaside environment, perspiration), wipe the frame clean promptly to prevent pitting corrosion from salt residue.

• Load-Bearing Component Check

Inspect load-bearing areas, including armrests and frame joints. Tighten as needed.

6000-Series Aluminum Alloy

• Rust Prevention

Avoid long-term exposure to moisture, which may accelerate oxidation.

• Deformation Handling

If minor deformation occurs from a small impact, it can usually be corrected under professional guidance (the material has better toughness and is not prone to cracking).

• Environmental Protection

Do not store the wheelchair in damp, dark places for extended periods. Apply a thin layer of anti-rust oil to the frame surface to enhance protection.

Universal Maintenance Guidelines (Both Materials)

• Daily Cleaning

Wipe the frame with a damp cloth or neutral cleaner to remove dust and perspiration. Dry completely afterward to prevent moisture buildup.

• Avoid Corrosive Contact

Keep away from acidic or alkaline substances (e.g., disinfectants, battery fluid). Rinse immediately with clean water if contamination occurs.

• Lubrication

Apply lubricant to bearings and folding joints every three months to reduce wear.

• Proper Storage

Store in a dry, well-ventilated place. Avoid prolonged exposure to sunlight.

Maintenance Schedule by Material Type

Clear routines by material help extend component lifespan.

Material Type	Maintenance Guidelines
7000-Series Aluminum Frame	1. Daily: Wipe off sweat and dust to prevent salt buildup. 2. Monthly: Check armrests and frame joints. 3. Every 6 months: Inspect for cracks or deformation; apply grease to bearings/joints.
6000-Series Aluminum Frame	1. Daily: Wipe with a cloth and neutral cleaner; dry completely. 2. Weekly: Clean sweat-prone areas; apply thin anti-rust oil in humid environments. 3. Every 6 months: Check oxidation; lubricate joints; adjust slight deformation if needed.
600D Flame-Retardant Oxford Fabric	1. Daily: Wipe stains; use neutral detergent for tough spots. 2. Monthly: Inspect for tears or loose stitching; repair promptly. 3. Quarterly: Air-dry in ventilation; avoid harsh chemicals to protect flame-retardant coating.
300D Pearl Cotton (Seat Cushion Inner Layer)	1. Monthly: Inspect for moisture. 2. Every 6 months: Open the cover and check for deformation or damage; air-dry if damp (no direct sunlight).
30D Foam (Backrest Inner Layer)	1. Monthly: Check rebound and odor; ventilate if necessary. 2. Every 6 months: Remove the cover and check for dents or damage; use low heat to dry damp spots.
12 mm Wood Board (Seat Support Layer)	1. Monthly: Check for flatness or loosening. 2. Quarterly: Open the seat to check for mold or cracks; air-dry if moisture is detected.

Notes

• Storage: Keep dry, ventilated; avoid humidity, high heat, or sun exposure.

• Emergency Treatment: If exposed to acids, alkalis, or salt, rinse with clean water and dry immediately to prevent corrosion.

Daily Tasks (5 minutes)

For 600D Oxford fabric + 7000/6000 aluminum frames

• Wipe aluminum frame (especially armrests and joints) to remove sweat and dust.

• Clean Oxford fabric surface with a damp cloth.

• Ensure no salt or moisture remains on the frame.

Monthly Tasks (15 minutes)

For all materials

• Frame: Tighten screws; check oxidation spots.

• Oxford fabric: Check for tears or loose stitching.

• Foam/Pearl cotton: Press the cushion/backrest to check rebound; ventilate if damp.

• Wood board: Check flatness and listen for unusual sounds.

Quarterly Deep Cleaning (30 minutes)

For wood board, foam, pearl cotton, Oxford fabric

• Inspect wood boards and padding for deformation or damage.

• Air the Oxford fabric (avoid direct sunlight).

• Dry foam/padding using low heat or natural ventilation.

• Apply anti-rust oil on 6000-series frames.

Handle all components gently during disassembly.

Semi-Annual Professional Maintenance (40 minutes)

For aluminum frame, bearings, core support components

• 7000 series: Inspect for cracks or deformation.

• 6000 series: Remove oxidation if necessary (light sanding).

• Bearings/Joints: Apply lithium-based grease.

• Core parts: Replace damaged wood boards or degraded foam.

If unsure about crack inspection, contact after-sales support.
