Makita is meeting demand for cordless outdoor power equipment with the 40V MAX XGT Brushless 18 in. Chain Saw. With zero emissions, lower noise, and considerably less maintenance, the GCU04 delivers power equivalent to a 42cc gas chain saw via its efficient Makita-built brushless motor. The 18 in. guide bar and variable-speed trigger deliver 0-5,020 FPM for increased cutting speed. Convenience features include lateral chain tensioning, captured bar nuts, adjustable automatic chain lubrication, and a built-in L.E.D. on/off switch with auto power-off. This kit includes two 40V MAX XGT 5.0Ah batteries and a rapid charger, ready to run right out of the box.
