Troubleshooting

If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.

When diagnosing faults in operation of the tool, always make sure the hydraulic power source is supplying the cor- rect hydraulic flow and pressure as listed in the table. Use a flowmeter known to be accurate. Check the flow with the hydraulic fluid temperature at least 80 °F/27 °C.

	SYMPTOM	CAUSE	SOLUTION
	Tool does not run.	Power unit not functioning.	Check power unit for proper flow
			and pressure (3–9 gpm/11–34 lpm at
