LOCATING THE PROBLEM AREA
If the saw does not operate, the problem is either in the saw, the hoses, or the power supply. Locate the problem area as follows:
1. Stop the power supply.
2. Disconnect the existing saw from the hoses and power supply.
3. Connect a known working saw to the hoses and power supply. Refer to this manual for the proper hook-up procedure.
a.
If the known working saw operates, the problem is in the disconnected saw. See the Troubleshooting Chart.
b.
If the known working saw does not operate, the problem is probably in the hose or power supply. Proceed to Step 4.
4. Stop the power supply.
5. Disconnect the existing hoses from the known working saw and power supply.
6. Connect a different set of hoses to the known working saw and power supply.
a.
If the known working saw operates with the different set of hoses, the problem is in the disconnected hoses.
b.
If the known working saw does not operate, the problem is in the power supply. See the Engine manual for troubleshooting.
