QUADRANT TO BLADE
1. Lay the blade face down on some cardboard on
the fl oor to protect the fi nish.
2. Assemble the quadrant to the blade with the blade
ribs centered between the quadrant lugs. Secure
with two 3/4" x 5-3/8" clevis pins, washers and
cotter pins.
3. Thread one 5/8" nut halfway down on each of
two eyebolts. Hook a spring to each of the spring
brackets on the quadrant as indicated in the
diagram. Hook an eyebolt to the other end of each
trip spring.
4. Push the threaded ends of the eyebolts through
the two eyebolt brackets on the blade. Install a
second nut on each eyebolt.
CAUTION
Overtightening springs will not increase blade
trip force and can damage the springs.
5. Tighten the top nuts until the coils of the trip
springs begin to separate (a piece of paper such
as this instruction sheet should pass between the
second and third coils). Tighten the bottom nut
against the spring brackets to lock in place.
