Read the material instructions
Check the permitted cleaning method for the exact fabric, frame and wheels. Do not apply one product’s solvent, lubrication or machine-washing instructions to another.
Record the work
Use the service log for the date, task and parts used. Store receipts and serial numbers privately. A calendar reminder follows your chosen interval; it does not establish a universal service schedule.
Ask about faults
If a control, harness, brake or folding lock is damaged or not operating as described, stop relying on community guesses and contact the manufacturer or an appropriate service provider.
