When operating an internal combustion
engine in an enclosed area, make sure
exhaust fumes are piped to the outside.

OPERATION
This pump is designed to handle most
non-volatile, non-flammable liquids
containing specified entrained solids
and corrosives. Do not attempt to pump
volatile, corrosive, or flammable liquids
which may damage the pump or endan-
