Check and Adjust Twine Cutter Knife

CAUTION: Twine arms can move unexpectedly when twine arm power is on. Turn off power to twine arms when standing or placing hands near twine arms.

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

IMPORTANT: Make sure that cutter anvil is properly adjusted before adjusting knife. (See ADJUST TWINE CUTTER-TO-TWINE ARM in this section.)

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

NOTE: Make sure that knife edge is straight. If not, rotate, replace, or sharpen 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 knife, if necessary.
