Twine Electric Actuator Installation Adjustment

CAUTION: Twine arms can move unexpectedly when twine arm power is on. Stay out of the path of twine arms at all times when twine arm power is on. During service or adjustment procedures for twine arms or twine cutter mechanism, turn off power to twine arms BEFORE placing your hands in the path of twine arm travel.

If there is crop material which is holding twine arms from moving freely during twine arm cycle, it is recommended that twine arms be manually positioned to release any "hold" they may have on the crop material. Turn off power to twine arms. This will help to make the unplugging operation easier and prevent twine arms from moving unexpectedly while your hands may be in the path of the twine arms. Stay out of the path of twine arms at all times when power to twine arms is ON.

NOTE: The 556 Baler is illustrated for the following procedure. On the 456/456S Baler, actuator is installed on left-hand side.

If electric actuator has been removed or replaced, or the twine cutter tension adjustment cannot be made by moving washers on the cutter strap, make the following adjustment:
