The Wacker BTS 1140L3 cutoff saw, powered by a 6.1-hp two-stroke-cycle engine, uses a 16-inch-diameter blade and provides cutting depths to 5.7 inches. The new saw weighs 23.4 pounds and features a “Long-Life-Lubrication” (L3) piston with a special graphite surface coating to minimize piston and cylinder overheating during continuous operation. The BTS 1140L3 uses a multi-ribbed belt for power transmission and employs an air-cleaning system that automatically shakes dust from the primary filter.
