4. Operating Instructions
Your Sandberg Voodoo Gaming Chair offers several adjustment options for optimal comfort.
- Seat Height Adjustment: Pull the lever located on the right side of the seat base upwards to raise or lower the seat. Release the lever at the desired height.
- Backrest Recline: Pull the lever on the left side of the seat base upwards to recline the backrest. Release the lever to lock the backrest in position.
- Tilt Tension Adjustment: Rotate the knob located underneath the front of the seat base to adjust the tension for the rocking function. Turn clockwise to increase tension, counter-clockwise to decrease.
- Armrest Adjustment: Press the button on the side of each armrest to adjust its height. Release the button to lock.
5. Maintenance and Care
Proper maintenance will extend the life and appearance of your gaming chair.
- Cleaning: The chair's faux leather material can be cleaned by wiping with a damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Regular Checks: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the material to fade or crack.
- Weight Limit: Do not exceed the recommended weight limit for the chair to prevent damage and ensure safety.
6. Troubleshooting
If you encounter any issues with your chair, refer to the following common problems and solutions:
- Chair Squeaks: Check all bolted connections and tighten any loose screws. A small amount of silicone lubricant can be applied to moving parts if the squeaking persists.
- Chair is Unstable/Wobbly: Ensure all casters are fully inserted into the star base. Verify that the gas lift is properly seated in both the star base and the mechanism plate. Check all assembly screws for tightness.
- Gas Lift Not Functioning: Ensure the height adjustment lever is fully engaged or disengaged as required. If the gas lift still does not operate, it may require replacement.
- Difficulty Reclining/Locking Backrest: Check the recline lever for obstructions. Ensure the tilt tension knob is not set too high, preventing easy recline.
