Maintenance
■ Periodic inspection
To ensure efficient and smooth operation, perform periodic inspection. Be careful not to damage internal sliding parts
and plastic parts when dismantling the pump.
The magnetic force of a drive and a driven magnet is strong. Be careful not to catch the finger. Do not put electrical
devices such as a watch and a mag card close to those magnets.
