Crawler Sagging may occur on the tracks due to wear, so you are requested to adjust the track tension periodically. If the tension is not appropriate, the tracks risk detachment.
9.1 Adjustment method (1) Set up the machine on firm and level surface, retract the boom fully, and then rotate the boom to the right or left side of the chassis. (2) Set the “Boom stand B” and the “Wood block A” under the 1st boom section as shown in the figure below. Ａ Ｂ
Caution:
The “Wood block A” shall be longer than the width of the 1st boom section, and arrange it so that the boom comes to the center of the wood block. In the interest of safety, make sure the stand is stable.
(3) Press the boom against the wood block by lowering the boom slowly, and allow the clearance of 30～50 mm (1.2～2.0 in) between the track and the ground.
30 mm～50 mm (1.2 ~ 2.0 in)
Danger: • Be sure to conduct the boom operation from the “Lower control.” • Do not lift up the track more than 50 mm (2.0 in) above the ground. If the track is lifted up beyond what is necessary, the machine may become unstable.
