  Miranda GordonAug 7, 2025
  The IHI Compact Excavator might not travel fast and powerfully due to several reasons: * The hydraulic oil level may be low. Refill the oil to the specified level. * The pressure set for the relief valve could be lowered. * There may be a defect in the motor or reduction gear. * There may be a defect in the pump. * The crawler might be over-tensed. Adjust the tension on both the right and left sides to the regular value.
