CAUTION: Nozzle tip should always be directed
away from operator. Fuel from spray orifices
can penetrate clothing and skin causing serious
personal injury. Enclosing nozzle in a glass
beaker is recommended.
Before applying pressure to nozzle tester, be
sure all connections are tight, and fittings are
not damaged. Fluid escaping from a very small
hole can be almost invisible. Use a piece of
cardboard or wood, rather than hands, to
search for suspected leaks.
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.
Connect nozzle to nozzle tester. (See TEST INJECTION
NOZZLES earlier in this group.)
