Refer to illustrations on following pages to identify various locations that require lubrication.
Knifehead
Figure 4.78: Knifehead
Single Knife – 1 Place
Double Knife – 2 Places
IMPORTANT:
Overgreasing can cause knife to bend and make contact
with guards closest to knifehead. Check for signs of
excessive heating on first few guards after greasing. If
required, relieve some pressure by removing grease
fitting.
• To prevent binding and/or excessive wear caused by
knife pressing on guards, do NOT over grease
knifehead (A).
• Apply only 1–2 pumps of grease with a grease gun, or
just until knifehead starts to move away from arm. Do
NOT use an electric grease gun.
• If more than 6–8 pumps of grease gun are required to
fill cavity, replace seal in the knifehead.
• Check for signs of excessive heating on first few
guards after greasing. If required, relieve pressure by
pressing check-ball in grease fitting.
NOTE:
Use high temperature extreme pressure (EP2) performance with 1% max Molybdenum Disulphide (NLGI grade 2)
Lithium base grease unless otherwise specified.
