The manufacturer has designed this implement to be used with all its safety equipment properly attached to minimize the chance of accidents. BEFORE YOU START!! Read the safety messages on the implement and shown in your manual.
Page 7 SAFETY INSTRUCTIONS (continued) EQUIPMENT SAFETY GUIDELINES Safety of the operator is one of the main concerns in designing and developing a new piece of equipment. Designers and manufacturers build in as many safety features as possible. However, every year many accidents occur which could have been avoided by a few seconds of thought and a more careful approach to handling equipment.
