The EA4300FRDB is a best-in-class mid-sized Makita Chainsaw engineered with professional features. A key point of difference is the industrial 2-sided magnesium (not aluminum) crank case for less weight and added durability. For faster and easier starts, the spring-assisted starter with optimized engine management reduces force required for starting. The result is a versatile and durable chain saw with a superior power-to-weight ratio that delivers consistent performance, job after job.
