OPERATION GUIDELINES
DIGGING IN FROST OR HARD PAN
When digging in frost or hard pan, use carbide auger teeth and point. For digging in these conditions,
recommend using a slow speed and maximum down pressure. If auger head is allowed to slide, a tough ice
slick may form, which could prevent penetration. If digging is particularly severe, move the second section in
and out slightly or rotate the auger slightly to either side of vertical. This speeds digging by concentrating the
down pressure first on one side and then the other.
TILTING AUGER TO APPLY DOWN PRESSURE
NOTE: Always keep the auger rotating when doing this.
DIGGING DEEP HOLES
If it is necessary to dig holes deeper than 6 or 7 feet (2 m), move the auger to a lower attaching hole on the
hexagon extension shaft. This shaft is 60-inches (1.5 m) long and has several attaching holes that can be
used to extend the auger for deep holes or over an embankment. Do not stow auger in an extended position.
Return to shortest length before storing.
DIGGING DEEP HOLES OR OVER EMBANKMENTS WITH THE EXTENSION SHAFT
Too much side pressure can bend the auger stem.
