CAUTION: The nozzle tip should always be
directed away from the operator. Fuel from the
spray orifices can penetrate clothing and skin
causing serious personal injury. Enclosing the
nozzle in a clear glass beaker is recommended.
Before applying pressure to the nozzle tester,
be sure that all connections are tight, and that
the fittings are not damaged. Fluid escaping
from a very small hole can be almost invisible.
To search for suspected leaks, use a piece of
cardboard or wood, rather than hands.
If ANY fluid is injected into the skin, it must be
surgically removed within a few hours by a
doctor familiar with this type injury or gangrene
may result.
1. Connect injection nozzle to nozzle tester.
