Inspecting the High-Pressure O-Rings
[NOTICE] The High-Pressure Hoses need to be checked for wear every 20 – 50 hours. If you do not properly identify wear in the High-Pressure O-Rings, they can become damaged and lead to a severe leak.
To check the High-Pressure O-Rings:
Follow the “Safety Instructions” on the “Hose Disconnect Procedure” label next to both sides of the High-Pressure Hose connections. This includes:
Ensure the High-Pressure Hose is purged by selecting Setup & Maintenance > Maintenance > Nozzle Purge on the Control Panel. Allow the Nozzle Purge cycle to finish.
Turn off WAZER.
Disconnect Pump Box and WAZER Power Cables.
Disconnect Pump Box Signal Line.
Turn off the water supply.
Unplug Water Inlet Hose.
[WARNING] Disconnect both sides of the High-Pressure Hose before inspecting it. To completely disconnect it pull back on the knurled collet of the Connector and pull the hose out of the Connection.
Look into the ends of the High-Pressure Hose Connector and check to see if the O-Ring is frayed, worn, misaligned, or otherwise damaged and needs to be replaced.
If one or both of the High-Pressure O-Rings look damaged in any way, simply replace them with one of the spare O-Rings we provide in the Spare Parts accessory bag. If you are out of spare O-Rings, please contact WAZER Customer Support for replacements.
To replace the High-Pressure O-Ring:
• Push a fresh high-pressure O-ring into the connector and use a pick or needle nose pliers to push it into place. You should see it nest inside the connector if installed correctly.
• Reconnect the High-Pressure Hose to WAZER and Pump Box. If your O-Rings were damaged, ensure that the High-Pressure Hose does not bend or turn aggressively.
After re-installing the High-Pressure Hose, it is important to follow the guide Maintenance > Maintenance > Priming the machine Hydraulics to get rid of any air in the High-Pressure system before stating to cut again.
