3.2 Lubrication
Remove the lubrication plug from the lubrication port, and add the pump oil which has been
delivered together with the pump or the pump oil specified by us (SMR-100) up to the range
marked with the line on the oil level gauge. When making the first lubrication, add oil near to
the upper oil level limit shown on the oil level gauge. After lubrication, mount the lubrication
plug to the pump (see Fig. 4).
Always keep the oil level of the pump within the oil limit range shown on the oil level gauge
during operation. If the amount of oil is incorrect, the performance of the pump will deteriorate
resulting in the malfunctioning of the pump. When the amount of oil has reduced and the oil
level has reached an area below the lower line which shows the lower limit on the oil level
gauge such that the level cannot be seen, the ultimate pressure increases and exhausting sound
may not cease.
Remove rication plug from the lubrication port, and add the pump oil which has been delivered
together with the pump or the pump oil specified by us (SMR-100) up to the range marked with
the red line on the oil level gauge. When making the first lubrication, add oil near to the upper
oil level limit shown on the oil level gauge. After lubrication, mount the lubrication plug to the
pump (see Fig. 4).

① Wear protective equipment such as rubber gloves and safety goggles.
② Be sure to read the attached “Safety Data Sheet” before adding oil. If
the oil accidentally comes into contact with your hands or enters your
eyes, take proper measures in accordance with the section “First-aid
treatment” shown in “Safety Data Sheet.”
Use only oils specified by us. If other oils are used, the pump performance
will deteriorate or its life will be shortened.
