Note 1) Tank pressure is the pressure of Auto Feed Tank and line pressure is the pressure of Auto Feed Lube.
Note 2) Conditions: primary pressure 0.5 MPa, 5 drops/min, turbine oil class 1 (ISO VG32), temperature 20°C, needle fully open. Use air consumption rate for minimum operating flow.
Note 3) Capacity between levels; in the case of a float switch equipped model, the capacity is measured in levels between the level gauge upper limit and the lower limit of the float switch detection range.

Precautions
Mounting
- *If the line pressure is discharged, the oil could flow back if the operating pressure differential range (the difference between the tank and line pressures) exceeds 0.6 MPa. Therefore, make sure to also discharge the tank pressure.
- *Install the float vertically inside the bowl so that it will not come into contact with the siphon tube to prevent the oil from dripping poorly.
Maintenance and Inspection
*The auto-feed lube cannot be replenished while it is pressurized. Replenishing the lubricant from the cam handle (lubrication plug) of the auto feed tank is recommended.
*See the manufacturer's catalog for product information other than the above.
