6. Operating Instructions
Your Benmar Office Chair offers several adjustments to customize your seating experience:
- Seat Height Adjustment: To raise the seat, lift the lever located under the right side of the seat while taking your weight off the chair. To lower the seat, lift the lever while seated. Release the lever at your desired height.
- Tilt Function: The chair features a tilt mechanism allowing the backrest and seat to recline together. Pull the lever (usually on the left side) outwards to unlock the tilt. Lean back to recline. Push the lever inwards to lock the chair in an upright position.
- Tilt Tension Adjustment: The round knob located under the front of the seat controls the tension of the tilt mechanism. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).
- 360-Degree Swivel: The chair's seat can rotate freely 360 degrees for easy movement and access to your workspace.
7. Maintenance
Proper care will extend the life and appearance of your office chair:
- Cleaning: Wipe the leather upholstery and stainless steel frame with a dry or damp cloth. Avoid abrasive cleaners or harsh chemicals that may damage the finish.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability and safety.
- General Care: Keep the chair away from direct heat sources and sharp objects to prevent damage to the upholstery and frame.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not adjust height. | Gas lift cylinder is not engaged or is faulty. | Ensure the height adjustment lever is fully engaged. If the problem persists, the gas lift may need replacement. |
| Chair is wobbly or unstable. | Loose screws or improper assembly. | Check and tighten all assembly screws. Ensure casters are fully inserted into the base. |
| Chair squeaks during movement. | Loose connections or lack of lubrication. | Tighten all screws. Apply a small amount of silicone-based lubricant to moving parts if necessary. |
| Difficulty reclining or locking tilt. | Tilt tension is too high or tilt lock is engaged. | Adjust the tilt tension knob counter-clockwise to loosen. Ensure the tilt lock lever is pulled outwards to unlock. |
