ABOUT THE TROUBLESHOOTING SECTION​

Notes on troubleshooting and servicing​

OVERALL MACHINE​

No operation is possible.​

All systems working, but insufficient power.​

Lift arm and bucket fail to move or are too slow.​

TRAVELING​

Traveling fails.​

Right or left travel speed decelerates and the machine veers to one side.​

Operating temperature of the travel system is too high.​

2nd-speed travel is not possible.​

LIFT ARM​

Arm cylinder does not move​

Arm cylinder moves too slowly or lacks force​

When the control lever is pulled slowly, the lift arm drops once.​

Spontaneous drop of the lift arm is too large.​

BUCKET​

Bucket cylinder does not move.​

Bucket cylinder is slow or lacks force.​

Spontaneous drop of the bucket is too large​

SERVICE​
