FILLER AND VENT ASSEMBLY
The air vent assembly (Figure 1, Item 33) located in the top of the reservoir is provided to establish a zero pressure
condition in the reservoir during operation of the pump assembly, permitting a free low of luid. The air vent must
be closed when the jack is not in use to prevent luid leakage and contamination of the luid by dirt and moisture.
