REMARKS
CLEANING (Cont)
g. The exterior surface of an
injector spray tip may be
cleaned by using a brass wire
buffing wheel. To obtain a
good polishing effect and
longer brush life, the buffing
wheel should be installed on a
motor that turns the wheel at
approximately 3000 rpm. A
convenient method of holding
the spray tip while cleaning
and polishing is to place the
tip over the drill end of the
spray tip cleaner tool and hold
the body of the tip against the
buffing wheel. In this way, the
spray tip is rotated while
being buffed.
CAUTION
Do not buff excessively. Do not use a steel wire buffing wheel or the spray tip
holes may be distorted.
h. When the body of the spray tip
is clean, lightly buff the tip
end in the same manner. This
cleans the spray tip orifice
area and will not plug the
orifices.
WARNING
Wear protective eye goggles when using compressed air to prevent eye injury.
i. Wash the spray tip in clean
fuel oil and dry it with
compressed air.
