Office Chair Fixed Legs
The installation methods and wobble handling solutions for fixed legs of different models of office chairs are as follows:
F28 New Inclined Leg Chair Legs: For installation, prepare 4 coarse-medium screws (8x30) and 4 fine-extended screws (6x40). First, use the angle iron as a connecting component and initially fix the footrest to the corresponding position on the seat cushion with the coarse-medium screws. Then, use the fine-extended screws for further reinforcement to ensure a tight connection between the footrest and the seat cushion. This model of chair legs can have their height adjusted by rotating a knob to meet the needs of different usage scenarios. If the chair legs wobble, level them by installing foot pins: first, place 2 washers on the foot pins, then align and tighten the foot pins at the bottom of the chair legs, and do the same on the other side. If there is still slight unevenness, slightly rotate the foot pins on one side for adjustment.
w901 Inclined Leg Chair: During installation, place the washer between the crossbar and the footrest. The function of the washer is to increase the stability of the connecting parts and reduce wear. Then, use 4 medium screws to fix the crossbar to the footrest, ensuring the accurate relative position between the crossbar and the footrest. Finally, use 4 long screws to fix the footrest to the seat cushion, completing the overall installation. During the installation process, pay attention to the tightening force of the screws to avoid loose connections due to insufficient tightening or damage to the components due to over-tightening.
Chair NB98: This model fixes the five-star base to the seat cushion through a connector and 2-centimeter hexagon socket screws. The design of the five-star base provides more stable support, and the connector ensures precise alignment between the five-star base and the seat cushion. During installation, accurately insert the hexagon socket screws into the corresponding holes and tighten them with appropriate tools. After fixing the five-star base to the seat cushion, connect the overall structure through a gas spring. The gas spring not only provides support but also enables height adjustment of the seat.
