GENERAL DESCRIPTION
Accoustical Panels - The exclusive purpose of the accoustical panels is to control the sound level of the
operation of the earth auger, and do not contribute to the operation. Maintenance of most components requires
the removal of one or more panels for accessibility.
Air Cleaner - A Donaldson 5BG Series is designed for fast, easy disassembly so that it may be serviced
efficiently and quickly. The air cleaner should be inspected periodically to maintain maximum engine protection
and maximum service life.
Auger Bar - Is made of a high grade of AISI-4142H steel. The auger bar is a 2-1/2 inch square with round
corners. The auger bar is also referred to as the Kelly Bar. It is hydraulically fed for crowd and mechanically
rotated for drilling.
Auger Shaft - It is also known as the Feed Ram. It is the cylinder providing the hydraulic feed for the crowd of
the auger bar.
