ADJUSTMENT

Generally, the TC-2

™

trailer control brake valve should

deliver full reservoir pressure; however, there are a few
exceptions in special applications.

1. If the delivered pressure is below specifi ed fi nal delivery

pressure, it can be adjusted by removing the head and
the adjusting ring lock washer and rotating the adjusting
ring clockwise to raise the delivery pressure.

2. If the delivery pressure is above the specifi ed fi nal

delivery pressure, it can be lowered by rotating the
adjusting ring counterclockwise.

A spanner wrench can be used to rotate the adjusting ring,
but if such a wrench is not available, the adjusting ring
can be turned with a small screwdriver inserted in one of
the inner notches of the ring. Turning the adjusting ring
one notch will raise the delivered pressure approximately
5 psi.
