Centeralized Lubrication Unit Adjustment

1) Adjusting pump delivery

• The delivery amount to each lubrication point is controlled by the metering type distribution valve with automatic intermitent lubrication pump, and no further adjustment is necessary.

• A metering type distribution valves are provided at the machine rear(inside the cover) and at the right side of the tailstock. The delivery condition of lubricating oil can be checked visually. (Use sufficient care when checking the delivery condition.)

2) Maintenance and countermeasure.

When no lubricating oil is delivered :

a) Oil level is low. Replenish the lubricating oil of the same brand.

b) The pump is at a rest: The pump operates intermittently.

The pump operation interval is set at 5 minutes.

c) The oil strainer is clogged. Clean the oil strainer at least every six months. (See Fig. E-8.)
