Use of non-Titan service parts may void warranty.

Ask for original parts made by Titan for best

services. This pump should receive a routine

servicing after approximately 1,000 hours of use.

Earlier servicing is required if there is excessive

leakage from the top packing or if pump strokes

become faster on one stroke or the other.

The use of Titan Piston Lube (P/N 314-480) is

recommended as an upper packing lubricant.

Do not substitute oil, water, or solvent for an

upper packing lubricant.
