Page 10: Pressure Relief Procedure
Installation Pressure Relief Procedure Air Lock Procedure Follow the Pressure Relief Procedure whenever you see this symbol. The reference letters used in the following instructions refer to the Typical Installation F . 1 on page 6. An air lock occurs when a bubble or pocket of air pre- vents the normal flow of the lubricant. - Page 11 Installation • It may take up to 20 the pump strokes to expel the air from the pump and deliver a continuous flow of grease. This will depend on the viscosity of the lubricant and temperature. • Allow a minimum of 5 seconds ON time for the for- ward stroke and 5 seconds OFF time for the return stroke.
