The following instructions are intended to assist users installing StrongArmDOT 28 operator. StrongArmDOT
operator differs from standard StrongArm models by inclusion of a breakaway arm bracket, adjustable arm
height, and quantity of counterweights used. Please read all assembly instructions before installing the kit.
NOTE: Maintain tagged service nut on breakaway king pin during installation. Remove service nut after
installation is complete and breakaway bracket is fully secure.
1. If necessary, reposition operator side arm mounts on arm height adjustment legs to adjust operator
arm height. See "A" in drawing on next page.
2. See Arm Length and Counterweights Table (on previous page) for operator arm length and
counterweight options 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 "B" in drawing on next page.
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 "C" in drawing on next page.
5. Rotate breakaway king pin so alignment pin aligns with cast adapter shear brass bolt mounting
locations (3). See "C" in drawing on next page.
6. Align cast adapter and breakaway king pin with the forward panel of the conversion bracket. Use an
open-ended wrench to resecure bolt, lock washer, and flat washer to breakaway king pin head. See "C"
in drawing on next page.
7. Using a socket and ratchet, secure three brass shear bolts, lock washers, and hex nuts to the cast
adapter and conversion bracket. See "D" in drawing on next page.
NOTE: For initial installation, install two brass shear bolts and hardware. Number of brass shear bolts used is
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.
8. Using a socket and ratchet, secure the gate saver sleeve arm to cast adapter, and gate saver barrier arm
to gate saver sleeve arm using six bolts, flat washers, and nylon locknuts. See "E" in drawing on next
page.
