CAUTION
• When working on slopes or when working with trailer, set the wheel tread as wide as practical for maximum
stability.
• Support tractor securely on stands before removing a wheel.
• Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be
accidentally lowered. If necessary to work under tractor or any machine elements for servicing or
adjustment, securely support them with stands or suitable blocking beforehand.
• Never operate tractor with a loose rim, wheel, or axle.
