Oil injection plug (injection port)

(2) How to Inject Oil

Inject oil through the oil injection port so that oil level reaches the center of the red circle in the oil gauge.

Oil gauge

Approx. 8 mm

Proper oil level range

NOTICE: If the oil level is below the lowest point of the red circle, pump performance may be degraded or oil may be deteriorated earlier than usual. Conversely, if the amount of oil is excessive,

oil may be blown out. Hence, the proper level of oil should be maintained.

(3)The oil used in this pump is NEOVAC MR-100(supplied by Matsumura Sekiyu).

(4)If oil has accumulated in the oil holder located at the center bottom of the rotary pump, you should push up the oil holder from the bottom of the base, remove the oil holder carefully and dispose of the oil in the oil holder.
