1.3.4 Thoroughly inspect the area where the equipment is to be used and remove all stones, sticks, wires, bones, and other foreign objects which may damage the equipment or cause personal injury to the operator or bystanders. WARNING POTENTIAL HAZARD ♦ Engine exhaust contains carbon monoxide, which is an odorless deadly poison. WHAT CAN HAPPEN ♦ Carbon monoxide can kill you. HOW TO AVOID THE HAZARD ♦ Do not run engine indoors or in a small confined area where dangerous carbon monoxide fumes can collect.
DANGER POTENTIAL HAZARD ♦ In certain conditions gasoline is extremely flammable and highly explosive. WHAT CAN HAPPEN ♦ A static charge can ignite gasoline vapors. A fire or explosion from gasoline can burn you, others, and cause property damage. HOW TO AVOID THE HAZARD ♦ Purchase and store gasoline only in an approved container. ♦ Always place gasoline containers on the ground away from your vehicle before filling.
WARNING POTENTIAL HAZARD ♦ Operating engine parts, especially the muffler, become extremely hot. WHAT CAN HAPPEN ♦ Severe burns can occur on contact. ♦ Debris, such as leaves, grass, brush, etc. can catch fire. HOW TO AVOID THE HAZARD ♦ Allow engine parts, especially the muffler, to cool before touching. ♦ Remove accumulated debris from muffler and engine area. ♦ Install and maintain in working order a spark arrester before using equipment on forest-covered, grass-covered, or brush-covered unimproved land.
• See inside the back cover to determine the approximate slope angle of the area to be mowed. • Progressively greater care is needed as the slope increases. • Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope. • Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering.
