Fuel System
TEST AND ADJUST INJECTION NOZZLE
OPENING PRESSURE
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 injured by escaping fluid, see a doctor
immediately. Any fluid injected into the skin
must be surgically removed within a few hours
or gangrene may result. Doctors unfamiliar with
this type of injury may call the Deere &
Company Medical Department in Moline, Illinois,
or other knowledgeable medical source.
