Troubleshooting (OMAX Maxiem 1515)

Startup Problems

Turning on the air supply causes the bulk abrasive hopper to rattle and make a loud noise.

The tank has depressurised overnight when the air compressors are turned off and the person before you didn't close the AIR IN valve on the bulk abrasive hopper.

• Close the AIR IN valve on the bulk abrasive hopper.
• Remove the lid.
• Clean the mating surfaces of the seal.
• Pull up on the seal T-handle and hold it in place.
• Turn ON the compressed air supply (AIR IN) at the hopper.
• Once the seal holds itself in place, replace the lid.

The low pressure charge pump won't turn on.

Check you have turned on the PUMP WATER tap all the way. There is a flow sensor in the pump water supply that prevents the low pressure charge pump from running dry if the water supply is not turned on.

If turning the water on doesn't solve the problem ask a member of technical staff for help.

Garnet Hopper Problems

The bulk abrasive supply hose is spraying garnet from the tool head garnet hopper!

The bulk abrasive hopper has probably run out of garnet and needs to be refilled. This is a straightforward process but be careful you do not run out of abrasive in the tool head hopper - this will stop cutting and spray water everywhere.

• Pause the machine using the blue pause button on the machine pendant.
• Ensure the lid is on the bulk abrasive hopper.
• Close the AIR IN valve on the bulk abrasive hopper.
• Open the DUMP VALVE. Wait for the hopper to de-pressurise.
• Close the DUMP VALVE.

This will release the pressure and stop the spray of garnet from the tool head hopper. Ask a technician to help you restock the bulk abrasive hopper.

Pump Problems

Resetting the high pressure pump VFD doesn't clear the fault and the VFD pressure indicator always reads 30.

This may be due to clogged water filters. There are two pairs of water filters on the waterjet - a pair located in the pump frame and a pair mounted to the end of the tank itself. Each pair of gauges should read approximately the same. Any pressure differential between the two gauges indicates it is time to change at least one of the filters.

Ask a technician to help resolve this problem.

The high pressure pump only runs for a few seconds before the VFD faults.

This is probably a filter issue as well. See above.

Operation & Movement Problems

The machine doesn't want to move anymore. There doesn't appear to be any errors, it just won't jog anywhere or start a job.

Check the transparent-fronted safety box on the side of the tank, next to the PC trolley. There is a small rocker switch on the side that sometimes gets knocked - this should be in the "on" position. Press the blue button once it's in the right position, then press the black button on the machine pendant.

The Z-axis makes an awful creaking noise when it moves.

It shouldn't! Ask a member of technical staff to look at cleaning and greasing the rails and lead screw ahead of the recommended maintenance schedule.

Cutting Problems

The material isn't cutting and water is spraying everywhere.

Check that garnet is flowing freely through the abrasive delivery hose. If there is moisture in the hose it must be cleaned out. Occassionally water makes its way into the tool head garnet hopper. In this case the abrasive solenoid and the hopper must be cleaned. Ask a member of technical staff for help with this.

The material isn't cutting properly - water is spraying everywhere but the garnet is definitely flowing.

This may be one (or many) of a few different issues.

• The material type is set incorrectly. Check the material settings and adjust as needed.
• The material thickness is set too thin. Measure the material and compare with the material setting. Adjust as needed.
• You are trying to cut too quickly. This occurs very rarely with very thick material and very low quality settings. Ask a member of technical staff for help adjusting the garnet flow or the machinability grade of the material.
• There's a clog in the abrasive solenoid which is reducing the abrasive flow rate. Ask a member of technical staff to show you how to unclog it.
