High-End Office Chair Repair
High-end office chair repair requires targeted handling based on the specific type of fault, with common repair methods including backrest gliding mechanism restoration, caster replacement, and selection of professional repair services.
1. Backrest Gliding Mechanism Repair
Taking the Sihoo C500 Second Generation Deluxe as an example, if the backrest bone block is loose and fails to stay securely in place, the back cover needs to be removed for repair. The specific steps are as follows: Use a tool to pry open the lower edge of the back cover, remove the five internal fixing screws, and then separate the aluminum alloy cup holder from the bone block connection structure. Check whether the card slots between the bone block and the cup holder are worn. If there is a gap, restore the tightness by adjusting the position of the cup holder or replacing worn components. After repair, repeatedly test the sliding resistance of the backrest to ensure smooth operation without any abnormal noise.
2. Caster Tilt and Replacement
When an office chair tilts to one side, it is necessary to first check the condition of the casters. Place the chair upright and upside down to observe whether the wheels make even contact with the ground. If bent or deformed casters are found, check the damage to each wheel individually:
- Removing Old Casters: Insert a flat-head screwdriver into the gap between the caster axle and the base, and gently pry to remove stuck wheels; if the wheels are fixed with screws, use the corresponding screwdriver to loosen and remove them.
- Installing New Casters: Apply a small amount of spray lubricant to the caster holes in the base, align the new wheels with the holes, and gently tap them in completely with a rubber mallet. After installation, invert the chair and manually rotate the wheels to test their smooth rolling, ensuring there is no jamming or deviation.
- Matching Models: When purchasing new casters, confirm that the diameter and axle length match those of the original wheels to avoid installation failure or further damage due to size mismatch.
3. Selection of Professional Repair Services
For complex issues such as air pressure pump leaks, armrest fractures, or five-star base deformation, it is advisable to contact a professional repair agency. For example, Shanghai Changfa Automatic Door Access Control System Installation and Repair Company provides comprehensive repair services for all components of high-end office chairs, including the repair and replacement of wheels, air pressure pumps, armrests, and other parts. Corporate users can sign long-term repair contracts to enjoy regular inspections and priority services, with repair fees negotiated based on the actual number of replaced parts. When selecting a service, it is necessary to confirm the agency's qualifications and request warranty periods for parts and repair records to safeguard after-sales rights.
Repair Precautions: Cut off the power supply before operation (if the chair has electric functions), and use professional tools to avoid damaging components; if unfamiliar with the structure, it is recommended to take photos of the state before disassembly as a reference to prevent difficulties in reassembly.
