SHEAR PIN REPLACEMENT
If gate arm is vandalized and the tapered pin in the output shaft
has been sheared, it must be replaced correctly and with the right
pin type. Replacement must be done by always punching out the
pin (or pieces) from the small end only. If drilling is required, DO
NOT DAMAGE THE SHAFT, use a drill bit smaller than the small
hole size of the pin. (Correct pin (P/N MA013) is a 2" pin with a
number 6 taper only.)
NEVER USE A BOLT AS A TEMPORARY FIX, THIS WILL
DAMAGE THE SHAFT AND COLLAR
1. Use S-3 to rotate bracket to up position
2. Turn off AC power and disconnect batteries small end first.
3. Remove gate arm bracket and pieces in collar

(Solid sharp blows are better than light ones)
