Unfortunately, our efforts to provide safe equipment can be wiped out by an operator’s single careless act. In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.
SAFETY RULES ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! Keep bystanders away from equipment. Never allow riders on power unit or attachment. Do not operate or transport equipment while under the influence of alcohol or drugs. MAINTENANCE Operate only in daylight or good artificial light. Keep hands, feet, hair, and clothing away from equipment while engine is running. Stay clear of all moving parts. Always comply with all state and local lighting and marking requirements.
