The Percussion Auger operation requires oil lubrication. The Lubricating Oil Tank stores oil of specifications ISO46~220. The tank is to be connected to the outlet of the air compressor leading to the air hose that connects the Percussion Auger. The regulating valve is adjustable to regulate the required amount of lubricating oil for the PAS operation. Constant supply of lubricating oil to the percussion auger is critical to prevent premature wear and damage to the internal mechanism.
