Use the power tool, accessories, tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• When working with the power tool always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
• Wear hearing protection. Exposure to noise can cause hearing loss.

попробую еще раз - mud shear guns, устанавливаются в амбарах (отстойниках) бурового раствора (pits), не могу нагуглить. какие-то гидромониторы? то ли для внутренней очистки отстойника, то ли для перемешивания раствора. Кто-нибудь знает, что за штуки?

Спасибо.
