• Park the machine on firm and level ground. • Block the articulated joint. • Apply the parking brake. • Loosen the wheel-nuts on the wheel to be replaced by about one turn. • If a rear wheel is damaged, raise the relevant side of the machine with the blade, turning the blade in such a way that one end of the blade is in front of the damaged wheel. Then raise the machine with the appropriate lifting cylinder. • If a front wheel is damaged, raise the machine with the blade or with the front grading blade (optional equipment). • Prop up the raised axle with squared timber so that it cannot sink back down. • Secure the machine as described under "Securing the machine".
• Inflate the tyres with the correct pressure. See "Tyre inflation pressures" and "Tyre pressure Safety instructions". • Check the wheel nuts after 5 operating hours with a torque wrench for tightness.
