Checking and Adjusting Twine Cutter Knife

Twine arms can move unexpectedly. To avoid crushing, keep hands out of the twine arm path. Turn off power BEFORE servicing or adjusting twine arms or twine cutter mechanism.

Stay out of the path of twine arms at all times when power to twine ares is ON.

Twine knife has two cutting edges. Be careful when working around the knife. It is sharp.

Make sure that cutter anvil is properly adjusted before adjusting knife. (See Adjusting Twine Cutter-to-Twine Arm in this section.)

Do not operate twine arm with the pickup in raised position, or damage to pickup teeth can occur.

Make sure that knife edge is straight. If not, rotate, replace, or sharpen the knife.

If knife edge is less that 3 mm (1/8 in) from rear of hex flat, the knife has become too short due to sharpening. Invert or replace the knife, if necessary.

1. Remove crop material from knife and hex anvil area.

2. Move twine arms behind twine cutter as follows:
