Office Chair Footrest Assembly

The assembly of footrests for different models of office chairs should be carried out step by step according to the specific structure, with core steps including component alignment, screw fixation, and phased leveling. Key details must strictly adhere to the model requirements.

Assembly Steps for W901 Inclined Footrest Chair

1. Crossbar and Footrest Connection: Place a gasket between the crossbar and the footrest contact surface, and use four medium-sized screws to initially fix the crossbar. The screws do not need to be fully tightened at this stage, leaving room for adjustment.
2. Footrest and Seat Cushion Fixation: Align the footrest with the mounting holes at the bottom of the seat cushion, and connect them with four long screws, keeping the screws loose as well.
3. Leveling and Tightening: After adjusting the levelness of the footrest, gradually tighten all the screws in a diagonal sequence to avoid local stress concentration causing structural misalignment.

Assembly Steps for W889 New Inclined Leg Chair

1. Footrest Steel Pipe Docking: Unscrew the reserved screws on the footrest, align the steel pipes on both sides, and insert them into the designated slots, ensuring a complete fit at the interface.
2. Screw Fixation: Use four reserved screws to pass through the corresponding holes in the steel pipes and the footrest, initially fix them, and then tighten them with a wrench, applying even force.
3. Foot Pin Installation: Slide a gasket onto the threaded part of the foot pin, vertically screw it into the threaded hole at the bottom of the chair foot, adjust the overall stability of the chair by rotating the foot pin, and finally confirm that all foot pins are in contact with the ground.

Assembly Steps for Red Heart Solid Wood Foot Office Chair

1. Gas Lift Insertion: Invert the solid wood chair foot, vertically insert the gas lift into the center hole of the chair foot, gently press until it is fully embedded, and check for no gaps at the connection.
2. Dust Cover Installation: Sequentially slide a small dust cover onto the upper part of the gas lift and a large dust cover onto the lower part, ensuring that the covers are flush with the surface of the chair foot to prevent dust from entering the internal structure.

Assembly Steps for Universal Computer Chair Footrest

1. Bracket Direction Confirmation: Install the footrest bracket with the horizontal hole facing the front of the seat cushion and the vertical hole facing the backrest direction to avoid restricted movement due to incorrect orientation.
2. Initial Screw Fixation: Connect the bracket to the chair body with screws, initially tightening them only until they cannot be turned by hand, leaving room for adjustment.
3. Adjustability Testing: After completing the installation of other components, adjust the angle of the footrest bracket according to usage habits, and finally tighten all the screws to fix the position.

Precautions:

• For the W901 and W889 models, tighten the screws in stages to avoid structural deformation caused by one-time locking.
• For solid wood chair feet, focus on checking the firmness of the connection between the gas lift and the chair foot to prevent detachment during use.
• When installing the footrest, the white plug only needs to be installed on one side (usually the non-movable side), and it is not necessary to install it on both sides.
