Miscellaneous Procedures
You may need to perform these tasks during setup, maintenance, or in response to cutting issues, conditions,
or wear you notice during use or routine maintenance.
Priming the Plumbing
Required for initial WAZER setup and restart after maintenance
This procedure will ensure that both the low-pressure and the high-pressure water lines have no
air in them and are fully primed with water, setting up your machine to have an error free and
flawless cut. This will take you less than 5 minutes but if it is not done, you may have your cut
interrupted by water leveling errors or an abrasive clog.
After your initial cut, this procedure will not need to be conducted under normal daily or weekly
operation, however you may need to conduct it in the future under certain conditions:
•
If the tank is drained, the low-pressure system should be re-primed.
•
If the low-pressure or high-pressure lines are disconnected,
the high-pressure system should be re-primed.
Preparation:
Once your WAZER is setup to the point of the tank being filled and the water being plumbed into
the Pump Box (see Setting Up WAZER & Cut Preparation), you are ready to Prime the Low-Pressure
System and then Prime the High-Pressure System.
To Prime the Low-Pressure System:
•
Fill WAZER tank as instructed
•
Open Drain Filter Cover, lightly tap Drain
Filters, to let trapped air escape. You will see
bubbles coming out.
•
Turn WAZER on.
•
Select the “Setup & Maintenance” on the
Control Panel.
•
Select “Peripheral Check”.
•
Remove the front bucket cover.
•
Select Low Pressure Pump (“LP Pump”) and
allow pumps to run for 15 seconds. During
this period observe the outlets of the used
abrasive collection system. You should see
the water stream go from being anemic to a
steady and strong stream.
•
Refill water in the tank to the level of the cut
bed. If you didn’t see a steady strong stream,
make sure to repeat by selecting “Low
Pressure Pumps” from previous step.
To Prime the High-Pressure System:
•
Turn WAZER on.
•
Select “Setup & Maintenance” on the Control
Panel.
•
Select “Peripheral Check” >“HP Valve”.
•
Remove the Abrasive Hose End
from Cutting Head. This is critical, do
NOT
omit this step!
•
Raise the cutting head approximately 0.5”
(13mm) above the cut bed surface so you
have room to observe the stream coming out
of the nozzle.
•
Make sure door is closed. Press OK.
•
Watch and listen to the stream carefully as
the air leaves the stream and it transitions to
just water. This can be both seen and heard
as the water stream will change from a white
irregular flow that makes a slight hissing
sound to a clear smooth stream that should
be silent. If your water supply pressure is
relatively low (< 40psi) or water supply lines
are long, you may need to select the “HP
Valve” option from step 4 multiple times to
get all the air out of the system.
