  • Page 3: Safety Precautions

    Important information and Safety precautions ▪ Safety precautions WARNING Install in a safe area. To prevent a fire or explosion, install in an area free of flammable gases or organic solvents. Never install outdoors. To prevent fire or electric shock, never install outdoors. Turn off the main electric source.
  • Page 4 Important information and Safety precautions WARNING Not for use as life support. Serious bodily injury and/or death may occur. Unit must only be used to compress air. Do not touch. Keep hands and fingers away from fans, pulleys and belts while the power is on. Serious injury, including entanglement of fingers or hands can occur.
  • Page 5 Important information and Safety precautions CAUTION Use at ambient temperatures of 36°F to 104°F. Drain will freeze at less than 36°F and will cause unit failure. Using over 104°F will cause a shorter lifespan or unit damage. Use in an area free of dirt and dust. Failure to do so may result in equipment failure.

    Maintenance and inspection Carry out the following maintenance and inspection items according to the schedule below. This interval is based on conditions where ambient temperature is at around 86°F. If your location is warmer or running condition is severe, maintain at a shorter period. 30% from our recommendation at every 9 degree F. The maintenance time differs from guarantee period.

  • Page 45: Daily

    Maintenance and inspection To keep your compressor in good condition for a long time, you must conduct proper inspection and maintenance. Consider periodic inspection as a minimum standard, shortening the time if necessary. ▪ Daily • Drain the condensate from the air receiver. Activate the drain valve of air receiver before releasing compressed air in air receiver, and Drain condensate from air receiver.
  • Page 46 Maintenance and inspection • Safety valve Lift the stem of the safety valve at about maximum pressure and blow it off. Then push the stem down. • Check ventilation fan Check the ventilation fan to see if it rotates correctly and exhausts air during compressor operation.
  • Page 47 Maintenance and inspection ▪ Every 2,000 hours or yearly • Replace the intake filter. フィルタ Filter • Check the belt tension. See if the V belt makes a slipping sound at the startup, due to decrease of the V belt tension. If so, readjust the belt tension or replace it.

  • Page 48: Every 2000 Hours Or Yearly

    Maintenance and inspection • Check leakage Close the stop valve at the air receiver outlet and push the operating switch of the compressor to operate. When all compressors stop operation at maximum pressure, push the stop switch and check the air pressure of the operating panel.
