The Makita 18V LXT Grease Gun Kit delivers 10,000 PSI of maximum pressure and a maximum flow rate of 10 oz. per minute. The grease gun also features an Auto-Speed mode, which automatically switches the flow rate to match the higher pressure of the part being greased based on resistance. This means more efficient greasing so users can get the job done faster and move on to the next zerk fitting. It’s powered by the same fast-charging 18V batteries that are compatible with over 275 LXT cordless products.
