Check the listing for details. 1/4” 13mm Pneumatic Pistol Drill with Forward & Reverse Rotation Pneumatic Drill. Condition: New. Listed at 54.89 USD. Suggestion for using pneumatic tools: ◆ Please inject 2-3cc of # 60 pneumatic lubricating oil (laundry oil) before and after daily use ◆After oil injection, please allow it to run freely for a few seconds ◆ Generally, in traditional air compressors, most of the gas compressed by the compressor contains water, as well as the lubricating oil carried out by the compressor piston. If an oil-water separator is not used, water and oil will enter the pneumatic tool with the gas, causing the fan blades to stick. If the tool moves together, it may not be able to shake the blades and may not start. If it can start, it will result in insufficient torque. It is important to inject pneumatic oil from the rear air inlet and then press the pneumatic tool to idle for a few seconds, The torque can be restored to normal
