Medium-Term Maintenance Procedures

Interval: 300 hours
(6,000 lbs. of abrasive)

Cleaning the Pump Box Air Filter

The pump box Air filter needs to be cleaned roughly every 300 hours. If the Wazer is located in a particularly dusty area it should be checked and cleaned more often.  A clean air filter allows the the pump box to run far cooler, prolonging the life of all the components inside

Nozzle Replacement

The nozzle assembly is wear component and needs to be replaced after around 300 hours of cutting. The following guide details the replacement procedure.

Replacing the Orifice

You will need to replace the WAZER’s Orifice after 300+hr of run time, when the performance of your WAZER starts to decline, or if the orifice is damaged.

Pump Box Oil Change

The Pump Box oil needs to be changed after the first 50 hours of use, and then every 300 hours after that.

Lubricating the Gantry

Keeping the gantry lubricated is important to ensure that it is able to move freely along the guide rods. An unlubricated gantry may bind up and cause issues with movement.


[WARNING] WAZER tracks the number of hours it has been running.
Please check the “Total Cut Time“ in the maintenance menu regularly. If you do not abide by the regular maintenance procedures and schedule, the warranty and support for your WAZER will be void.

Before servicing WAZER:

  • Turn off or close the On/Off Valve or water supply to the machine.

  • Purge the high-pressure system by properly ending/completing a cut or performing a Nozzle Purge.

  • Turn off WAZER and disconnect AC power from WAZER and the Pump Box.

  • Never remove the cover of the Pump Box while it is plugged in.
