— F-4 Even if power digging switch is pushed, power does not increase. Boom raise power is weak when performing digging operation.
— F-5 Boom, arm, or bucket single operation is not operated. Boom, arm, or bucket single operation speed is slow.
— F-7 When performing combined operation, arm does not start to move smoothly. Arm starts to move slightly slow when performing arm single operation. These troubles often occur when temperature is low.
— F-8 When performing combined operation, boom does not start to move smoothly. Boom starts to move slightly slow when performing boom lower single operation.
— F-9 Boom lower speed above ground is faster than other actuators when performing combined operation. Machine cannot be raised off the ground.
— F-10 Arm roll-in speed is slow when performing digging operation.
— F-11 Arm roll-in speed is fast when performing arm level crowding operation. Arm power is weak when performing digging operation.
— F-12 Arm roll-out speed is slow when performing combined operation of boom raise, arm roll-out, and attachment.
— F-13 Difficult to raise the machine off the ground.
— F-14 Bucket roll-in speed is slow when performing combined operation of arm roll-in and bucket roll-in. Attachment speed is slow when performing combined operation of attachment and arm roll-out.
— F-17 Bucket roll-in single operation speed is slightly slow. Bucket does not move smoothly in bucket roll-in single operation.
— S-1 Swing speed is slow or is not operated.
— S-2 Swing speed is slow when performing combined operation of swing and arm. Swing does not start to move smoothly. Swing power is weak.
— T-1 Both of right and left travels are not operated or travel speed is slow.
— T-2 One side travel is not operated or travel speed is slow. Machine mistracks.
— T-3 Machine mistracks when performing combined operation of travel and front attachment.
— T-4 Fast travel can not be selected. Travel mode does not change from slow speed mode to fast speed mode.
— T-5 Occasionally, machine may mistrack when traveling with engine running at slow speed.
— T-6 Attachment speed is slow when performing attachment single operation. Travel speed is slow when performing combined operation of attachment and travel.
— BL-1 Blade is not operated or moves slowly and power is weak.
— BL-2 Blade drifts remarkably
