Row Chair and Office Chair Installation

The installation of row chairs and office chairs should be carried out step by step according to the specific model, ensuring that the components are aligned and the screws are tightened to avoid omissions or incorrect installation.

Row Chair Installation (Taking the 311 Row Chair - Three-Seater as an Example)

1. Installing the Chair Legs

   • Use a large hex key to unscrew the screws on the chair legs and remove the iron plates.
   • Distinguish the front and back directions of the crossbeam: the right angle on the crossbeam's seat frame is the back, and the bevel is the front; the chair legs are shorter in the front and longer in the back.
   • Insert the chair legs into the left and right sides of the crossbeam, place the gaskets, and then screw in the screws to ensure a firm connection between the chair legs and the crossbeam.

2. Installing the Chair Back

   • Place the chair back on the crossbeam, aligning it with the hole positions of the small iron plates on the outside.
   • First, manually fix it with short hex screws, and then fully tighten them with tools to avoid screw slippage or loosening of the chair back.

3. Installing the Seat Cushion

   • Insert the card slot at the bottom of the seat cushion into the seat frame of the crossbeam, ensuring a complete fit between the card slot and the seat frame.
   • Screw in medium hex screws from the bottom at the front and long hex screws at the back, paying attention to matching the screw length with the hole positions to prevent penetration of the seat cushion surface.

4. Repeating Installation for Other Seats

   • Install the remaining two seats according to the above steps, ensuring that all screws are tightened to avoid abnormal noises or structural instability during use due to looseness.

Office Chair Installation (Taking Model 901 as an Example)

1. Checking the Goods

   • Check whether all accessories are complete, including the backrest, headrest, armrests, five-star base, decorative cover, 7 coarse screws, 6 short screws, and 5 wheels.

2. Installing the Five-Star Base

   • Insert the 5 wheels into the hole positions of the five-star base, ensuring that the wheels are properly installed and can rotate flexibly.
   • For other models, it may be necessary to place iron particles in the holes of the crossbeam and then fix them with long screws, depending on the specific structure.

3. Assembling Other Components

   • Depending on the model differences, it may be necessary to fix the backrest to the seat frame with coarse screws and connect the armrests or headrest with short screws.
   • Pay attention to aligning the components during installation to avoid damage to the screws or hole positions caused by forced screwing.

General Precautions

• Tool Usage: Select the corresponding hex key according to the type of screw to avoid slippage due to mismatched tools.
• Tightening Degree: All screws should be tightened, but avoid excessive force that may damage the threads.
• Safety Inspection: After installation, shake the chair to check for looseness or abnormal noises, ensuring structural stability.
