Care and Maintenance
Casters - Your casters do most of the work throughout the day and it is important that you clean them at least once a month. When used on hard floors or chair mats, casters will accumulate dirt and debris on the wheels. You can use a solvent based cleaner to wipe them clean. If you don't visually see debris, a canister or air will do the trick.
Hardware - Over time bolts and other hardware can become loose. You should go through your chair and tighten all hardware twice a year. This will help eliminate squeaks and ensure nothing is broken or damaged.
Lubrication - As you can imagine, lubricating your chair controls from time to time will be necessary. With all of the moving parts and the locking and unlocking of all the different adjustments, a can of white lithium grease will be your best defense against squeaks and creaks. RFM has specific diagrams for each of their chair controls (available upon request) that come in handy when it's time to lubricate parts.
Clutch Plate Adjustment - RFM chair controls are locked and released with the use of clutch plates. Over time with the constant adjusting of the seat, the clutch plates can start to loosen. As part of maintaining your chair you will need to tighten the clutch plates should they become loose and start to slip.
Upholstery - Vacuuming and a dry wipe down of your seat and back will help in keeping your upholstery fresh and clean. Spills on the fabric can be cleaned according to the fabric manufacturers specific instructions that are usually located on the back of the fabric card on their website.
