MAINTENANCE AND SERVICING
Every 25 Hours
Use high temperature extreme pressure (EP2) performance with 1% max molybdenum disulphide (NLGI Grade 2)
lithium base unless otherwise specified.
Knifehead: Lubricate the knifehead (A) every 25 hours.
Check for signs of excessive heating on the first few guards
after greasing. If required, relieve the pressure by pressing
the check-ball in the grease fitting.
IMPORTANT:
Over-greasing the knifehead puts pressure on the knife
causing it to rub against the guards, resulting in excessive
wear from binding. Do NOT over-grease the knifehead.
Apply only one to two pumps using a mechanical grease
gun (do NOT use an electric grease gun). If more than
six to eight pumps of the grease gun are required to fill
the cavity, replace the seal in the knifehead. Refer to
5.8.3 Removing Knifehead Bearing, page 347.
