PROPER LIFTING PROCEDURES
The following are guidelines for properly lifting the earth auger and auger bit from the hole. These guidelines are not intended to be all inclusive.
Plan your path and make sure there are no obstructions or tripping hazards. Consider how you set the load. The spinal column is a very sensitive
mechanism. At any given time, improper lifting procedures may cause damage that may lead to injury.
1) Position your feet at a comfortable distance (shoulder width) to help provide the necessary balance.
2) Tighten your stomach muscles by pulling in your stomach. Keep your back as straight as possible to keep the spine, back muscles and liga-
ments in correct alignment.
3) Remember to bend at the hips and knees as much as possible.
4) Start lifting the earth auger with a thrust of your feet while lifting as much as possible with your leg muscles. Use smooth movements.
5) Once you lift the earth auger, keep it close as possible to the body. Avoid turning at the waist. To turn, pivot your entire body.
6) Keep your shoulders, hips and feet pointed in the same direction.
7) Keep your footing firm and make sure that your intended path is clear before attempting to carry the earth auger.
MINIMIZING KICKBACK FROM AN OPERATIONAL STANDPOINT
Proper operator positioning enhances the control of the earth auger, reduces operator fatigue, and increase over all productivity.
1) Keep the left side of the handle as close to your body (left hip and leg areas) as possible to
minimize machine “kickback” when auger bit touches a buried obstruction.
2) Always keep in mind that the operating positions should allow your involuntary body reac-
tion against the torque sensation created by the digging process.
3) Keep upper arms as close to the upper body as possible to maximize mechanical lever-
age.
4) Keep your back as vertical as possible by bending the legs as required during the digging
process.
5) Positioning the left foot ahead of the right foot at a comfortable distance enhances proper
body position.
Maintaining proper operating position is one of the most IMPORTANT and EFFECTIVE proce-
dures for controlling kickback. Improper operating positions only increase the effects of kick-
back upon the operator.
Do not lean too far over the earth auger. Proper reaction and control may not be achieved in
the event of kickback.
CAUTION:
Maintain the operator handle and throttle control handle grip areas in good condition and free of moisture, pitch, oil or grease.
Wear gloves to improve your grip.
Bent or damaged handles, a throttle control with a damaged/no grip or handles without the gripping area material (PVC coating) increase the
effects of kickback. Do not operate the earth auger until such damage has been repaired or replaced. Damage to property and/or personal
injury can result.
