5. ติดที่วางแขน: Position the armrests on either side of the seat, aligning them with the pre-drilled holes on both the seat and the backrest. Use the appropriate screws (typically 'B' type) to attach them. Do not fully tighten these screws at this stage.
6. ติดพนักพิง: Align the backrest with the armrests and the seat. Use the remaining screws (typically 'C' type) to secure the backrest to the armrests.

คำแนะนำการใช้งาน

Your Amazon Basics office chair offers several adjustable features for personalized comfort:

• การปรับความสูงของที่นั่ง: To raise the seat, lift the lever located under the seat while taking your weight off the chair. To lower the seat, lift the lever while remaining seated. Release the lever at the desired height.
• ฟังก์ชั่นเอียง: The chair features a tilt mechanism. To enable tilting, pull the lever outwards. To lock the chair in an upright position, push the lever inwards.
• การปรับความตึงเอียง: Rotate the round knob located under the seat (usually at the front of the mechanism) to adjust the tension of the tilt. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
• หมุนได้ 360 องศา: The chair is designed with a 360-degree swivel for easy movement and multi-tasking.
• Rolling Casters: The five-point base with casters allows for smooth-rolling mobility across various floor surfaces.

การซ่อมบำรุง

To maintain the appearance and longevity of your chair:

• การทำความสะอาด: เช็ดทำความสะอาดด้วยโฆษณาamp ทำความสะอาดด้วยผ้า หลีกเลี่ยงสารเคมีรุนแรงหรือน้ำยาทำความสะอาดที่มีฤทธิ์กัดกร่อน ซึ่งอาจทำให้หนังเทียมเสียหายได้
• ตัวล็อค: Periodically check all screws and bolts to ensure they remain tight. Re-tighten as necessary to prevent wobbling or instability.
• ล้อ: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling.

การแก้ไขปัญหา

If you encounter issues with your chair, consider the following:

• เก้าอี้รู้สึกไม่มั่นคงหรือโยกเยก: Ensure all assembly screws are fully tightened. Check the gas lift cylinder for proper seating in the base and mechanism.
• Difficulty leaning back or adjusting tilt: Check the tilt tension knob under the seat. Rotate it counter-clockwise to loosen the tension. Ensure the tilt lock lever is disengaged (pulled outwards).
• Screws not fitting or stripping: Ensure you are using the correct screws for each step as indicated in the assembly instructions. Do not overtighten screws during initial assembly; tighten fully only after all components are loosely fitted. If a screw is stripped, contact customer support for replacement parts.
• ล้อเลื่อนไม่หมุนอย่างราบรื่น: Inspect casters for trapped debris (hair, lint) and clean them. Ensure they are fully inserted into the base.
