Note: Using lubricant on the vanes and vane slots during disassembly
and cleaning eventually causes a gummy residue to develop, rendering
the system inoperative.
DO NOT LUBRICATE VANES AND VANE SLOTS.
• Check the priming system by performing a “Dry Vacuum Test” per
NFPA standards. If the pump holds vacuum, but primer pulls less
than 22” Hg., it could indicate excessive wear in the primmer.
