TROUBLESHOOTING

If the attachment is not working correctly, check the hydraulic system of the machine thoroughly before making any
repairs on the attachment. Attachment problems can be affected by a hydraulic system that is not operating to
specifications. Connect a flow meter to the machine to check the hydraulic pump output, relief valve setting and tube
lines to check flow and pressure. (See the machine’s Service Manual for the correct procedure to connect the flow
meter.)
Use the following troubleshooting chart to locate and correct problems which most often occur with the attachment
