During work, it is necessary to strictly adhere to the safety rules, strangers should not be in the working area. The device must be used strictly for its intended purpose, if it is provided for a diameter of 200 mm, then there is no need to try to enlarge it.
Pay attention to how the engine idles. After releasing the control lever, it should not rotate.
During drilling, the operator must use protective hearing capsules to limit the perception of loud sounds. During long-term operation, observe short breaks to prevent engine cooling and worker fatigue. After finishing work, inspect the device for leaks from the fuel tank. It must be stored in a dry place, away from sources of ignition.
If you have not used the tool for more than three months, then the fuel tank must be emptied and well ventilated for commissioning.

Peculiarities
The founder of Stihl is Andreas Stihl, who opened his design office 90 years ago. At that time he had a logging industry, which was based on manual logging. It was this hard work that provoked the owner to quickly make an electric chainsaw. So over the years, the time has come for the production of a motor-drill.
A motor-drill is indispensable in everyday life and construction, because with its help they build supports for various fences, dig depressions in the ground, its use greatly facilitates the installation of supports, poles and much more. Stihl manufactures a variety of gasoline powered mobile augers. They differ in their power, fuel tank volume, revolutions, size and cost.
