A wheeled excavator is less stable on slopes than a crawler machine. Work across the slope rather than down it where possible, keep the blade or outriggers on the downhill side for support, and keep the bucket low.
Follow the gradeability limit in the operator's manual and reduce it further on wet grass, mud or loose gravel. If the machine starts to slide, lower the equipment and stop rather than steering out of it.
