Read and observe: “Wheels and tyres, safety instructions”. “Tyre pressure, safety instructions”. • Park the machine on firm and level ground. • Block the articulated joint. • Engage the parking brake. • Loosen the wheel nuts on the wheel to be replaced by about 1 turn. • If a rear wheel is damaged, raise the relevant side of the machine with the blade. Turn the blade so that one end of the blade is in front of the damaged wheel. Then raise the machine with the appropriate lifting cylinder.
• Tighten the wheel nuts by hand. • Remove the supports under the lifted axle and lower the axle. • Tighten the wheel nuts crosswise with the prescribed torque. For torques see “Fastening of wheels”. • Inflate the tyres to the correct pressure. See “Tyre pressures” and “Tyre pressure, safety instructions”. • Check the wheel nuts after 5 operating hours with a torque wrench for tightness. Î
• 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 “Securing the machine”.
