● Do not fill the fuel tank while the engine is running. Gaso-
line spilled on a hot engine may explode and cause serious injury to
personnel.
● Make sure all gasoline fumes are removed from tank before
starting welding operations. Fumes in tank can cause a severe explo-
sion if ignited.
● Do not start pump without first priming with water. Dry opera-
tion will damage pump seals and cause pump to fail. After priming, do
not run pump more than 3 to 5 minutes without water flowing through
it.
