The CS-302 is a professional-grade chainsaw that has been fabricated Echo between 1977 and 1983. Even though it’s long been replaced by newer models in Echo’s product line, models of this nimble and hardy CS-302 are still to be used by chainsaw fans, and reconditioned units and parts are easily available on the secondary market.
Engine Specs
The CS-302 is powered by an air-cooled, two-cycle, one-cylinder engine fueled by a gas-and-oil mix. It features a 30.1-cubic-centimeter piston displacement, and it is equipped with a magneto-type flywheel, either a Walbro or Tillotson carburetor depending upon the model year and an automatic rewind starter. The saw’s power mind, minus the guide bar and chain, weighs in at 9.9 lbs.
String, Bar and Chain Brake
Standard equipment on the CS-302 was a 12-inch guide pub, but the saw could be outfitted with a bar around 16 inches . Its series has a quarter-inch pitch and 0.05-inch gauge. The CS-302 wasn’t equipped with a chain brake, a security mechanism that stops the spinning of the series when the saw goes back, as standard equipment, but an optional string brake was accessible as an extra-cost add-on.
Starting Sequence
The CS-302 is equipped with a conventional starter system that needs adjustment of the throttle and choke levers during the beginning sequence. The string involves locking the throttle open, closing the choke, yanking the rotor rope, opening the choke if the engine starts to fire and disengaging the throttle after the engine starts. Some newer Echo models, like the CS-355T, are outfitted with reduced-effort launching systems featuring digital ignition; the maker asserts that these systems require 30 percent less effort compared to those used on models like the CS-302.
CS-303T
The version closest in specifications to the CS-302 in the 2014 Echo lineup is the CS-303T. Like the CS-302, the CS-303T is equipped with 30.1-cubic-centimeter two-cycle engine, and it comes standard with either a 12- or 14-inch guide bar. The CS-303T has digital ignition, but it has a standard beginning system instead of the higher-end reduced-effort system. The CS-303T is also outfitted with an inertia-type series brake, and at 7.7 lbs, it is significantly lighter than the CS-302.
