Other servicing that may be required is listed below:

• Periodic cleaning of the lubricator is desirable to

eliminate contamination that may have occurred in

the oil. To accomplish this, remove all pumping units

and clean the pumps and reservoir by brushing

loose all foreign matter, dipping in solvent and blow-

ing dry with compressed air.

• If external leakage is observed, determine the

cause (loose bolts, defective gaskets, or seals) and

repair as required.
