• Preventive maintenance is planned exchange, overhaul, modification, checking, etc. to prevent breakdown
beforehand and maintain the product usable.
• Contact the merchandise or service center for periodic maintenance.

frequency, pulse) is dynamic; operation time is long and exposed to dust, salinity, and oil mist environment;
vibration or shock is occurred; and the operation is operating out of range.
