Assembly Steps:

3. Insert Gas Lift: Place the gas lift cylinder into the center hole of the chair base.
4. Assemble Seat and Backrest: Secure the backrest to the seat using the provided screws and Allen wrench. Ensure all screws are tightened securely but do not overtighten.
5. Attach Armrests: Connect the armrests to the seat and backrest using the designated screws. The flip-up armrests should be oriented correctly.

4. Operating Instructions

The Sytas SLBY718 chair offers several adjustable features to customize your seating experience.

Adjustable Functions:

• Height Adjustment: Locate the lever under the right side of the seat. To raise the seat, lift the lever while standing. To lower the seat, lift the lever while seated. Release the lever to lock the height.
• Tilt/Rocking Function: The chair features a 135° tilt rocking function. Pull out the lever on the left side of the seat to enable rocking. Push it in to lock the chair in an upright position.
• Tilt Tension Adjustment: A round knob located under the front of the seat controls the tension of the rocking motion. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).
• Headrest Adjustment: The headrest can be adjusted vertically to three different levels. Gently pull up or push down on the headrest to set it to your desired height.
• Flip-Up Armrests: The armrests can be flipped up 90 degrees. This allows the chair to be pushed closer to a desk or stored compactly.

5. Maintenance

Proper maintenance ensures the longevity and performance of your Sytas office chair.

• Cleaning: Wipe clean with a damp cloth. For tougher stains on the PU leather, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
• Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack.
