Figure 5.9: Knifehead
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.

to rub against the guards, resulting in excessive wear from
binding. Do
NOT
overgrease 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. For instructions, refer to
