Page 8: Section 2 - Safety Information
2.1 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. -
Page 9: Operation Considerations
Section 2 2.3 BEFORE OPERATION CONSIDERATIONS (CONT'D) 6. If the operator(s) or mechanic(s) cannot read English or Spanish, it is the owner's responsibility to explain this material to them. 7. DO NOT wear loose fitting clothing. Loose clothing, jewelry or long hair could get tangled in moving parts. -
Page 10: Roll Over Protection System (Optional)
2.4 OPERATION CONSIDERATIONS (CONT'D) 3. To prevent tipping or loss of control, start and stop smoothly, avoid unnecessary turns and travel at reduced speed. 4. When using any attachment, never direct the discharge of material toward bystanders or allow anyone near the machine while in operation. - Page 11 Section 2 This mower has been designed for good traction and stability under normal mowing conditions. However, caution must be used when traveling on slopes, especially when the grass is wet. Do not mow on wet grass. Wet grass reduces traction and steering control. Any or all parts of the Roll Over Protection System MUST NOT be removed.
