How should I maintain my button?

The best way to ensure the smooth function of your button is an annual service carried out by a qualified professional.

But proper maintenance is a year-round job. Check your unit regularly for dust and debris, cleaning any bits of dirt you find with a smooth microfibre cloth (not supplied). Apply 2ml of warm water on the cloth using a fine pipette for stubborn marks and be sure to wear safety goggles at all times.

Run a test sequence twice a week, or four times a week in complex or humid conditions.

Carry out a visual inspection before and after each use. Using a small amount of specialist oil can often help ensure the smooth function of the button over time.
