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).

IMPORTANT: Periodically check lines to ensure that 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, normal plunger stroke will be interrupted when it reaches the outlet port (H) of the clogged line. Clear the obstruction as follows:

Determine which line is clogged by estimating how far plunger (B) has moved. This can be verified by disconnecting the suspected oil line at bearing and moving plunger (B).

After disconnecting line, move plunger (B) to determine whether clogging is in the bearing or in the oil line.

Clean bearing if clogged and refill with John Deere Multi-Lube Lubricant before attaching multi-luber feed line. If oil line is clogged, operate pump until lubricant is forced through the line.
