Although hazard control and accident prevention are partially dependent upon the design and configuration of the vehicle, these factors are also dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the vehicle. Improper use or maintenance of the vehicle can result in injury or death. To reduce the potential for injury or death, comply with the following safety instructions. WARNING To reduce the potential for injury or death, comply with the following safety instructions. Before Operating 1. Read and understand the contents of the Operator’s Manual and Operator’s Video before starting and operating the vehicle. Become familiar with the controls and know how to stop the vehicle and engine quickly. A replacement Operator’s Manual is available on the Internet at www.Toro.com or by sending the complete model and serial number to: The Toro Company Attn. Technical Publications 8111 Lyndale Avenue South Bloomington, Minnesota 55420­1196 2. Keep all shields, safety devices, and decals in place. If a shield, safety device, or decal is defective, illegible or damaged, repair or replace it before operating the vehicle. Also tighten any loose nuts, bolts or screws to ensure vehicle is in safe operating condition. 3.
