8.2 MAINTENANCE
8.2.1 GX920XT DIPPER EXTENDER CONTROL:
The dipper extension feature on the GX920 requires some extra maintenance. There is a grease zerk
found on the peddle rocker block, and is accessible from the operators station, just under the foot rest.
Grease should be applied annually.

8.2.2 GX920XT DIPPER BOOM EXTENDER:
The dipper boom extension features two high strength plastic slides on each side and between the sliding dipper
and dipper base. These slides feature good abrasion & wear properties, and therefore
do not require any lubri-
cation.
