Landscapers and contractors are demanding more cordless alternatives to gas-powered outdoor power equipment. Makita is meeting demand with an expanding line of cordless OPE, including the 40V max XGT® Brushless 18” Chain Saw (GCU04Z).

With zero emissions, lower noise, and considerably less maintenance, the GCU04Z is a welcome solution for cutting and trimming applications. It’s powered by one 40V XGT® 5.0Ah battery for power and longer run time, and with the efficient Makita-built brushless motor users get high power efficiency that is equivalent to a 42cc gas chain saw.

The GCU04Z has an 18” guide bar and Makita-built motor with a variable-speed trigger that delivers 0-5,020 FPM for increased cutting speed. It has zero emissions and reduced maintenance: there's no engine oil to change, no spark plug to replace, and no air filter or muffler to clean. And there's no need to drain the fuel for storage.

Convenience features include lateral chain tensioning with dual stud for efficient chain retention, captured bar nuts, adjustable automatic chain lubrication with large oil reservoir, and a built-in L.E.D. on/off switch with auto power-off function which automatically shuts the saw off when operation is delayed for extended battery life.

XGT® is a system of equipment, tools, batteries, and chargers utilizing 40v max lithium-ion batteries. XGT® is engineered to deliver high power to take on high-demand applications, allowing users to completely transition to a cordless job site. XGT® is equipped with advanced brushless motor engineering, intelligent digital communication, and superior durability features to outpower, outsmart and outlast the rest.
