OPERATION

TO FILL CONTAINER:

1. Raise lever and wipe off tip of container.

2. Loosen knurled thumb screws and slide cover to one side.

3. Fill container with lubricant, being careful that no air pockets are formed.

TO USE:

1. Check condition of hose and check to see that all connections are secure.

2. ADJUSTMENT INSTRUCTIONS:

Set lever at appropriate position (Figure 11)

a. for lightweight lubricants and warm temperatures.

b. for lubricants of medium thickness.

c. for cold weather and/or thick lubricants.

(To change positions, remove wing nut 79882 and slide pin 322423, with the wing

nut still attached, into alternate hole.)

2. Wipe fitting and coupler and place coupler on fitting.

3. Pump lubricant into bearing. Remove coupler.

4. Wrap hose around bucket and attach coupler to fitting on top of container. On most

models, this fitting serves as a pressure release and allows excess lubricant to run

back into the container.

IF PUMP FAILS TO BUILD UP PRESSURE OR DELIVER LUBRICANT:

1. Check if lubricant level is low or if air pockets have developed, allowing air to enter

pump.

2. Check hose and connection for leaks.

3. If pressure still fails to build up, overhaul pump with Major Repair Kit 398724 or

replace.
