5. Operating Instructions

The hjh OFFICE Shake 100 chair offers several adjustment options to customize your seating experience.

5.1. Seat Height Adjustment

To adjust the seat height, locate the lever typically found under the right side of the seat. While seated, pull the lever upwards to lower the seat. To raise the seat, stand up slightly and pull the lever upwards. Release the lever at the desired height to lock it in place. The seat height can be continuously adjusted thanks to the gas spring mechanism.

5.2. Rocking Mechanism and Tilt Tension

The chair features a rocking mechanism that allows for relaxed tilting. To activate or deactivate the rocking function, locate the lever under the seat (often the same lever as for height adjustment, pushed inwards/outwards). To adjust the resistance of the rocking mechanism, turn the rotary knob located under the seat. Turn clockwise to increase tension (less tilt) and counter-clockwise to decrease tension (more tilt), adjusting it individually to your body weight.

This diagram illustrates the key adjustable features of the chair, including the gas lift lever for seat height adjustment and the rotary knob for tilt tension control, along with various views of the chair's components.

6. Maintenance

Regular maintenance helps prolong the life and appearance of your chair.

• Cleaning: The fabric material can be cleaned with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners. Spot clean as needed.
• Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
• Casters: Keep the casters free from hair and debris to ensure smooth movement.

7. Troubleshooting

If you encounter any issues with your chair, refer to the following common solutions:

• Chair Squeaks: Check and tighten all assembly screws. A small amount of silicone spray on moving metal parts (avoiding the gas lift cylinder) may help.
• Chair Does Not Adjust Height: Ensure the gas lift lever is fully engaged or disengaged. If the gas lift is faulty, it may need replacement.
• Chair Feels Unstable: Verify that all casters are properly inserted and all screws on the base and seat mechanism are tightened. Ensure the chair is on a flat, even surface.
• Casters Not Rolling Smoothly: Clean any debris (hair, dust) from the caster wheels.
