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 hammer drill, always check that the hydraulic power source is supply- ing the correct hydraulic fl ow and a pressure to the tool as

listed in the table. Use a fl owmeter known to be accurate.

Check the fl ow with the hydraulic fl uid temperature at least 80o F / 27o C.
