Adjust Billhook Tongue

CC7858-UN-23SEP98

A - Stud

B - 23—68 N (5—15 lb.)

C - 3 mm (0.12 in.)

Adjust billhook tongue pressure when tongue is free of twine.

Billhook is properly adjusted when an outward pull of 23—68 N (5—15 lb.) (B) on billhook tongue will separate jaws of 3 mm (0.12 in.) (C). Tongue must be tight when closed.

To increase pressure on billhook tongue, tighten nut on stud (A). Loosen nut to reduce pressure.

Excessive pressure on billhook tongue may cause knots to remain on the billhook, thus breaking the twine. Incomplete knots may be the result of insufficient pressure on billhook tongue.

IMPORTANT: When using thick sisal twine (150 m/kg; 74.5 yd/lb.), correct billhook tongue pressure is 23 N (5 lb.), otherwise excessive stress on knotter parts will result during wiping operation.
