Follow the recommended procedure for removal and installation of tires and or wheel assemblies.Ensure that the machine and tire and or wheel assembly are properly supported at all times.Improper procedures that are used to remove and install tires and or wheel assemblies can result in personal injury or death.
Improper blocking of the rear axle housing can cause personal injury.The rear axle housing is made to oscillate. During removal and installation of the rear tires and rims, the rear axle housing must be prevented from oscillating.Place wood blocks between the rear axle housing and the rear main frame to prevent oscillation of the rear axle housing.
Note: The following procedure is performed on the front axle. The procedure for the rear axle is similar. Park the machine on firm level ground. Apply the parking brake and block all the wheels except the wheel that requires removing.
Raise the front or the rear of the machine until the tire and rim to be removed is just off the ground.
