Office Chair Immobility Issues-Ehang Furniture

Immobility issues with office chairs may involve problems with multiple components and require troubleshooting based on specific symptoms.

Foreign Objects Stuck: Check for paper scraps, hair, threads, or other debris around the wheels. Use tweezers or a soft brush to carefully clean them, avoiding damage to the wheel structure.
Wheel Damage: Observe if the rubber part is severely worn or cracked. If rolling is affected, replace the wheel with a new one, ensuring the model matches.
Axle Issues: Check if the wheel axle is loose or rusty. Tighten the screws if loose; spray rust remover to eliminate rust and then add lubricating oil (such as WD-40) to restore rotation.
Floor Problems: Adjust the chair's position to a flat, smooth surface (such as tiles or wooden floors) to avoid increased resistance from carpets or uneven surfaces.
Dust and Dirt Accumulation: Regularly wipe the wheel surface with a neutral cleaner and a soft cloth to reduce friction.
Old Wheels: After long-term use, wheels may become worn and aged, requiring replacement to restore smoothness.

Improper Operation: Check if the control lever under the seat has been accidentally pushed in or not fully pulled out. Adjust it to the correct position to release the lock.
Foreign Object Blockage: Clean the bottom of the backrest, the pivot area, and the gaps in the base for any loose clothing, data cables, or other foreign objects that may cause physical obstruction.
Mechanical Failures:
- Hydraulic System Failure: If the hydraulic rod (gas lift) is damaged, contact a professional for repair or replacement.
- Lock Block/Tongue Failure: When the lock tongue moves abnormally, is worn, or breaks, disassemble and replace the lock block assembly.
- Lock Post Deformation: If the lock post is bent, causing misalignment and jamming, correct or replace the lock post.
- Control Tab Damage: When the metal tab is broken or deformed, replace the base control components.
- Spring Failure: If the thick spring loses elasticity or breaks, replace it with a new one to restore the reset tension.

Height Adjustment Stuttering/Noises: Apply lubricating grease (such as white lithium grease) at the connection between the base and the gas lift to reduce metal friction.
Inflexible Rotation: Apply white lithium grease (NLGI 2 viscosity grade) to the base turntable track to restore smooth rotation.
Loose Armrests/Difficult Adjustment: Disassemble the armrest height adjustment buckle and apply a small amount of lubricating grease to the internal rack to reduce wear.
Backrest Rebound Failure: When the plastic gear set of a synchronous backrest is worn, apply food-grade lubricating grease to restore rebound function.
Poor Caster Rolling: Each year, use a cotton swab dipped in lubricating grease to coat the wheel axle to reduce the impact of dust friction.
