for ideal operator performance.
3. Using a socket and ratchet, secure conversion bracket to two Gate Saver Yokes using four bolts, eight
flat washers, four lock washers, and four nuts. See StrongArm CounterWeight Installation, B, on the

4. Using an open-ended wrench, remove the bolt, lock washer, and flat washer from the breakaway king pin
head attached to the cast adapter. See Figure 1, C.

dependent upon arm length and anticipated wind load. Shorter arms may require one brass shear bolt. Longer
arms in windy areas may require three brass shear bolts.
