Section 2 INTRODUCTION Your mower is only as safe as the operator. Carelessness or operator error may result in serious bodily injury or death. Hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of the personnel involved in the operation, transport, maintenance and storage of the equipment.
If the operator(s) or mechanic(s) cannot read English or Spanish, it is the owner's responsibility to explain this material to them. DO NOT wear loose fitting clothing. Loose clothing, jewelry or long hair could get tangled in moving parts. Do not operate the machine wearing shorts; always wear adequate protective clothing including long pants.

Section 2 To prevent tipping or loss of control, start and stop smoothly, avoid unnecessary turns and travel at reduced speed. Use caution when operating the mower on an incline with the optional grass catcher installed. When using any attachment, never direct the discharge of material toward bystanders or allow anyone near the machine while in operation.
ROLL-OvER PROTECTION SYSTEM WARNING The seat belt must be securely fastened during operation. Failure to do so could cause serious injury or loss of life.
