1.
Stop engine and remove the key.
2.
Check guards for signs of heating during run-up due to
insufficient clearance between guard and knife.
3.
Check gap between knifehead (A) and pitman arm (B). A
business card should slide easily through the gap. If not,
adjust gap by loosening bolt (C), and tapping knifehead (A)
with a hammer. Retighten bolt.
IMPORTANT:
Overgreasing can cause the knife to bend and make contact
with the guards closest to the knifehead. Check for signs of
excessive heating on first few guards after greasing. If
required, relieve some pressure by pressing the check-ball
in grease fitting.
