• A reacting motion may occur on the auger when
spinning drill has hit on stones or tree roots
under the ground. Always hold the auger
securely to control such motion.
• Start drilling with half-throttle, and gradually
increase the engine speed so that the drill may
get into the ground smoothly.
• When the drill has been caught in the ground
and cannot be pulled out, stop the engine and
rotate the auger counter-clockwise.
