INTRODUCTION

Safety Symbol and Signal Words This manual and decals on the machine warn of safety hazards and should be read and observed closely. Manitou Group, in cooperation with the Society of Automotive Engineers, has adopted this: This symbol is used throughout this operator’s manual and on the decals on the machine. It identifies potential safety hazards, which, if not properly avoided, could result in injury. When you see this symbol in this manual or on the machine, you are reminded to BE ALERT! Personal safety is involved!

• It is the owner’s or employer’s responsibility to fully instruct each operator in the proper and safe operation and maintenance of the machine. A storage location is provided behind the operator’s seat for storing the operator’s manual. After using the manual, return it to the storage container.
• This manual is considered a permanent part of the machine and should be with the machine at all times. If the machine is resold, include this operator’s manual as part of the sale. Replace this manual promptly if it becomes damaged, lost or stolen. Some illustrations in this manual may show doors, guards and shields open or removed for illustrative purposes only.
• BE SURE all doors, guards and shields are in their proper operating positions BEFORE starting the engine to operate the machine. Because of ongoing product improvements, information included in this manual may not exactly match the machine. Manitou Group reserves the right to modify and improve products at any time without notice or obligation.
