Clean the flange machine daily. Use these supplies:

Mild spray cleaner or soap and water

CAUTION: Do not exceed 30 psi (2 bars) when using compressed air for cleaning purposes.

Dirt and lint accumulation is the most common cause for a poorly operating machine. Lint build-up can destroy certain machine parts. It may be necessary to remove covers to access areas housing some components.

CAUTION: Do not service any of the pneumatic components until the unit is relieved of air pressure. Always wear a mask or turn your face away from the regulator when releasing air pressure. Oil, residue, and debris from the floor may spray with force into the air.
