Benner Nawman BNGS710 Gas Cut-Off Saw

Two piston rings are better than one. Our saws have two piston rings which make it more efficient and extends the life of the engine. Competitors like the Makita only have one ring. Our tool has chrome coated cylinders much like the ones you would find in a high performance race car.

The coating reduces friction and wind resistance so more air is drawn into the combustion chamber, which results in better fuel mixture, more power, and longer engine life. The carburetor in this tool is the same model used in Husqvarna and Stihl saws.

The patented air duct system has angled fan blades on the flywheel that dramatically increases the air flow over the cylinder increasing power and efficiency. The saw has a three stage (foam and fiber) air filter to thoroughly remove even the smallest dust particles. The Saw is both Environmental Protection Agency (EPA) & California Air Quality Resource Board (CARB) Certified.

A sealed clutch bearing prevents oil from leaking on the shaft. Most other saws use an open oil lubrication system which can leak and cause maintenance problems. With the sealed clutch you won't experience this problem. A cylinder pressure release valve releases the pressure from in the cylinder and makes pulling the start cord much easier.

This tool has a powerful 71cc 4.4 hp engine that is strong enough for your highest quality blades. A speed regulator prevents over revving, keeping your saw from breaking down and extending the life of your blades. This tool has a Full 90 Day Warranty
