Test 6 – bucket test at the pump
1. Turn OFF the power. Remove the pump outlet, coolant line, and place it in a 3.8 liter (1 gallon) container.
AHypertherm coolant container works well.
2. Measure how long it takes to fill the container. Turn ON the power. Turn ON the pump manually using the manual
pump control button on your CNC screen (see step 1 under “Manual pump operation”). Write down how long it
takes to fill the container.
If it takes more than 65 seconds to fill the container, replace the pump and check the motor shaft for damage.
If it takes less than 65 seconds to fill the container, check the coolant supply line (from the power supply to the RHF/
LHF console) for kinks. If no kinks are found, replace the by-pass valve and perform this test again. If it still takes more
than 65 seconds to fill the container, replace the hoses between the power supply and RHF/LHF console.
