Manitou Americas reserves the right to make changes or improvements in the design or construction of any part of the unit without incurring the obligation to install such changes on any previously delivered units.

Abbreviations

Purchase equivalent, quality XPRT tires for your loader. Contact your dealer for replacement tire information. Replacement batteries are not provided by Manitou Americas.
