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 cutoff saw, always check that the hydraulic power source is supplying the correct hydraulic flow and pressure to the cutoff saw as listed in the table. Use a flowmeter known to be accurate. Check the flow with the hydraulic oil temperature at least 80 °F/27 °C.
PROBLEM | CAUSE |
| REMEDY |
Tool does not run. | Power not functioning. | Check power unit for proper flow and | |
|
| pressure (15 gpm at 2000 psi/56 lpm | |
|
| at 140 bar). | |
| Coupler or hoses blocked. | Remove obstruction. | |
| Mechanical failure. | Disassemble tool and inspect for | |
|
| damage. |
|
Tool runs backwards. | Pressure and return reversed. | Correct hose connection or flow di- | |
|
| rection. Motor shafts with | |
|
| threads | rotate counterclockwise, |
|
| motor shafts with | |
|
| rotate clockwise. | |
Oil leakage between motor housing | Oil tube | Replace as required. | |
and | Motor face seal failure. | Replace as required. | |
Backpressure too high. | Should not exceed 250 psi at 15 | ||
|
| gpm/17 bar at 571 pm measured at | |
|
| the end of the tool operating hoses. | |
| Pressure and return reversed. | Correct for proper flow direction. | |
Saw cuts too slow. | Insufficient oil flow or low relief valve | Adjust oil flow to proper gpm. For | |
| setting. | optimum | performance adjust relief |
|
| valve to 2250 psi/155 bar. | |
| Wrong wheel for material being cut. | Use correct wheel. | |
Saw gets hot. | Hot oil or excessive oil flow. | Check power unit for adequate cool- | |
|
| ing; should maintain fluid at or below | |
|
| 140 °F/60 °C. Power unit may be | |
|
| producing more flow than the saw | |
|
| will accept under the existing cutting | |
|
| conditions. Reduce flow until saw | |
|
| performance starts to drop off. | |
