Read entire instructions before beginning to install the loader. Personal injury and machine damage may be prevented if you read and understand these instructions and special safety messages.

TRACTOR PREPARATION

TRACTOR FRONT TIRES - Use front tires of equal size and maintain equal pressure in each tire. The pressure of the front tires must be increased to the maximum approved pressure recommended by the tire manufacturer to compensate for additional load placed on the tires with the Front End Loader. See your tractor Operator Manual. Adjust the front tires to the widest recommended setting on adjustable mod- els for maximum stability. Front end weights must NOT be used while loader is on the tractor.

Observe tractor preparation guide in loader Operator Manual. Pay particular attention to “minimum tread settings” information in your Mounting Kit Installation Instructions.

TRACTOR REAR TIRES - Maintain equal pressure in each of the rear tires. Use the widest recommend- ed rear wheel setting for maximum stability.

IMPORTANT: Do not exceed the maximum load capacity of the tires on your tractor. See Tire and Wheel Specifications in tractor Operator Manual for more information.
