Maintenance

To ensure the longevity and optimal performance of your BOLISS Drafting Chair, follow these simple maintenance guidelines:

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the materials.
• Regular Checks: Periodically inspect all screws and bolts to ensure they are tight. Re-tighten if necessary.
• Caster Care: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling.

Troubleshooting

Here are solutions to common issues you might encounter:

• Foot Ring Slips Down: The foot ring may occasionally slip if not tightened sufficiently. To resolve this, ensure the locking knob is tightened very firmly. For a more permanent solution, some users have found success by adding a standard metal hose clamp just below the foot ring on the lift cylinder and tightening it securely.
• Chair Does Not Adjust Height: Ensure the protective cap cover has been completely removed from the gas lift cylinder during assembly. If it was not removed, the cylinder will not function correctly.
• Squeaking Noises: Check all bolted connections and tighten any loose screws. Applying a small amount of silicone lubricant to moving parts can also help.
