Twine Electric Actuator Installation Adjustment

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

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

NOTE: The 547 Baler is illustrated for the following procedure. On the 447 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:
