Checking Multi-Luber (Optional)

IMPORTANT: Periodically check lines to ensure lubricant is reaching all outlet ports.

When operating properly, plunger will move through its full stroke without difficulty. If an oil line or bearing becomes clogged, the normal stroke of the plunger will be interrupted when it reaches the outlet port of the clogged line. Clear the obstruction in the following way:

1. Determine which line is clogged by estimating how far the plunger (A) has moved. Disconnect the suspected oil line at bearing and move plunger (A).
2. After disconnecting the clogged line, move plunger (A) to determine if the obstruction is in the bearing or the oil line.
3. Clean bearing if clogged, and refill with John Deere Multi-Luber lubricant or its equivalent befor4e attaching multi-luber feed line. If oil line is clogged, operate the pump until lubricant is forced through the line.

CAUTION: Do not force oil through oil line with a pressure grease gun. Burst pressure of the oil line is 20,685 kPa (207 bar) (3000 psi )
