System Operation

Pump Module
The pump module provides pressure and pressure relief function necessary for injector operation according to timer
programming.
1. Fill and prime pump module reservoir per instruction manual 308955 for air-powered systems and
manual 309098 for hydraulic-powered systems.
2. Bleed supply lines.
Run the primed pump at reduced output pressure to slowly fill the supply lines with lubricant. Remove the fitting
at the end of each branch line to allow air to escape from the line.
3. Bleed feed lines (two methods).
a. Disconnect the line from the bearing and cycle the automatic lubrication system until lubricant has filled all
the lines.
b. Disconnect the line from the bearing. Using a grease gun and the zerk fitting on the injector, fill the lines
with lubricant.
4. Set timer according to system requirements. See Instruction Manual 308950.
