Proper service and repair are extremely important for safe machine operation. The service and repair techniques recommended by Komatsu and described in this manual are both effective and safe. Some of these techniques require the use of tools specially designed by Komatsu for the specific purpose.

• If the shoe bolt is not loosened (if its rotational torque is not reduced to zero) even after it is loosened by 1 turn, loosen other bolts so that the bolt can be removed smoothly.
• Do not rotate the bolt forcibly when the torque is not zero. Otherwise, the bolt and link are deformed and become adhesive, and the maintenance work is required.
• When moving the shoe assembly, be careful not to damage the master link.
• If the gas cut of the shoe nut is performed to remove it by necessity, keep the seal temperature 80 °C or less, and take measures to prevent flame-cutting droplet from entering the clearance between links (to prevent seal deterioration due to heat).
