The EA4300FRDB Mid-Sized Chain Saw is engineered with an industrial two-sided magnesium (not aluminum) crank case for less weight and added durability. The spring-assisted starter with optimized engine management reduces force required for starting. Unlike common spring-aided starters, Makita's easy-start feature combines spring-aided engineering with a new low spark ignition coil that includes memory-power-ignition (IPM) technology. With IPM, the ignition coil requires much lower revolutions of the flywheel to fire. IPM stores energy from pulling the rope and running the saw which creates a stronger spark.
Additional features include a fleece air filter with a two-piece cover that opens simply by turning a knob for true tool-less access, as well as a single choke/run/touch stop switch engineered for added convenience over common two-switch designs. Consistent with all Makita chain saws, the EA4300F40B comes with a two-point inertia/mechanical chain brake, and metal (not plastic) spike bars for added durability.
