V1.2
Digger Safety and
Operation
A more detailed description of these components is provided in the following
Service and Maintenance section. The digger drive (and digger wind-up) is controlled by
a level located at the operator’s station. Right next to the level is another that opens and
closes the hydraulic stow latch mechanism, located inside the digger stow bracket.
The AUGER ROTATION level controls the direction of the auger flighting.
Operating it in a clockwise direction will turn the auger flighting in the “dig” direction, and
will un-stow the auger from the stow bracket on the side of the boom once the AUGER
LATCH is opened.
*NOTE* Stow auger only in the proper direction as indicated by this document,
and by the AUGER DEPLOY AND STOW PROCEDURE decal at the operator’s
station.
