Do not wear loose fitting clothing, scarves, neckties, jewelry or any item that may become tangled in surrounding growth or the chain saw itself. • Wear shoes with non-skid soles. DO NOT wear open toed shoes or operate unit barefooted. • Wear no-slip, heavy duty work gloves to improve your grip on the chain saw handles. The gloves also help reduce the transmission of machine vibration to your hands. HOT HUMID WEATHER • Heavy protective clothing can increase operator fatigue which may lead to heat stroke. Schedule heavy work for early morning, or late afternoon hours when temperatures are cooler. AVOID HOT SURFACES • During operation, the muffler or catalytic muffler and surrounding cover become hot. • Never suspend the saw on a lanyard with the engine running. • Always use the saw from the right-hand side of your body - NEVER from the left side. • Always wear proper safety clothing to protect your lower body from sharp saw chain and hot muffler. • Always keep exhaust area clear of flammable debris during transportation or when storing, otherwise serious property damage or personal injury may result. CS-450P 8 SPARK ARRESTOR MUFFLER • The spark arrestor muffler controls the exhaust noise and prevents hot, glowing particles of carbon from leaving the muffler. Make sure the spark arrestor screen is in good repair and properly seated in the muffler. • Certain internal combustion engines operated on forest, brush, and/or grass-covered areas in the states of Washington, Oregon, Idaho, California, Minnesota, New Jersey and Maine, are required to be equipped with a spark arrestor. This requirement also applies to all U.S. Forest Service lands. In some of these areas, the spark arrestor system must be certified per USDA Forest Service Regulation SAE J335. Check with your local or state authorities for specific regulations in your area. Failure to follow these requirements is a violation of the law.
