Bird Technologies 6730B Series - Manual (Page 29)

Models 6736A and 6736-030A;
1. Replace the vent plug, P/N 2450-094, with the
shipping plug, P/N 2450-049. Make sure to use
the O-Ring seal to avoid leakage.
2. Stand the unit on its back end, with the connec-
tor up, and brace it if necessary to prevent it
from tipping over.
3. Loosen the 10-32 x 1-1/2 inch screw on the clamp-
ing band and remove the clamping band.
4. Grasping the RF connector, slowly lift the load re-
sistor assembly out of the radiator tank allowing
the excess coolant to drip back in.
5. Inspect the O-Ring seal to be sure it is free of
twists and positioned evenly around the beveled
flange of the resistor housing. If the O-Ring is
not soft and pliable or shows signs of surface
cracks, replace it with P/N 5-230.

Oil
Models 6732B, 6734B, 6734B-030, 6737A and 6737-030A.
1. Put the diaphragm back in place on the radiator
tank.
2. Press the cuplike swelling in the center of the di-

trapped air bubble. To allow the air to escape,
pry the diaphragm away from the edge of the
tank.
3. Through the same opening add more oil, if neces-
sary, until the oil level is flush with the top of
the tank.
4. Replace the diaphragm cover and the clamping
band.
