Note: For some applications of the machine, the
repeated duty cycle of the front linkage may only
require small angular movements of the boom or
stick. There might not be enough angular motion in
order to distribute the grease between the pin and
the bearing. The operator should operate the boom,
the stick and the implement in order to distribute
the grease within the joint assemblies.
Service a new machine after Every 10 Service
Hours only within the initial 100 service hours.
Illustration 279
After the initial 100 service hours of operation,
service the boom, the stick, and the implement
linkage after Every 50 Service Hours.
Note: If the machine is operated under severe
conditions that might cause abrasive material to
enter the bearings, service the linkage after Every
10 Service Hours.
1. Wipe all fittings before you apply lubricant.
Use Steps 1.a through 1.c to ensure proper

4. Apply lubricant through fitting (3).
Note: This fitting supplies grease to all other
bearings except the bearings on the stick end
through a distribution valve. The distribution valve
is designed to give the proper amount of grease to
all bearings. If the distribution valve will not accept
grease, one of the lines is blocked.
