intrOdUctiOn
Lincoln Model 3650 20-gallon Used Fluid Evacuator
is designed for evacuating fluids (except gasoline
or other fuels) from automotive reservoirs. Recom-
mended fluids include engine oil, gear and trans-
mission oils, power steering fluid, coolants, brake
fluid, and other similar fluids.
It utilizes a venturi that operates on compressed air
between 90 and 150 PSI (6 to 10 bar), to develop
vacuum in the 20-gallon (76-liter) tank. The vacuum
is transferred via an evacuation hose from the tank
to a wand or adapter, which is immersed into a res-
ervoir of fluid, and the fluid is drawn into the tank.
