The Warthog nozzle is an invaluable partner for your jetter if you keep it at full performance


Without question one of the most popular tools in the industry is the Warthog nozzle. With the right jetter, it is capable of cutting roots and clearing grease. If you purchased your jetter from Jetters Northwest, there is a good chance you already own and are using this valuable tool.

Jetters Northwest wants to ensure that those of you who own a jetter are getting the most from your investment. So lets talk about maintenance.

The most important component of keeping your Warthog at its full performance is to replace the viscous fluid that lubricates the seal and bearings, but also slows the tools rotation. This should be done on a regular basis. The factory recommends refreshing the oil every 40 hours of tool use and replacing the seal as needed (between 150 and 300 hours).

To fill the tool with viscous fluid: (Basic instructions for WT-3/8 and WS-1/2 inch models)

  1. Fill the syringe with viscous fluid. This is best done by unscrewing the handle from the tube and pulling out the plunger. Pour fluid into the tube; reassemble the syringe.
  2. Hold the Warthog with the inlet end up. Remove the port screw from the Warthog. Thread the syringe fitting into the port, and slowly squeeze fluid into the swivel until excess fluid comes out around the inlet end. If the fluid coming out appears dirty or watery, keep squeezing in new fluid until it comes out clean.
  3. Remove the syringe from the Warthog and install the port screw.

In addition, on the WT-3/8 model with the carbide inserts, now is a good time to check the inserts and retaining screws for tightness. You can remove loose screws and re-install them with a drop of Loctite 242 (removable) or similar thread lock. On WS-1/2 models this is a good time to look at the condition of the head and whip hose.

Of course you should also check the nozzle jets regularly for wear or blockage.

Other tips:

  1. Learn your tool. Listen to your Warthog’s rhythm. A change in cadence is the first sign something is not right.
  2. Look at cleaning patterns left behind with your camera. Incomplete coverage will tell you your tool is rotating too slow, or not at all, or possibly that you are moving the tool too fast for effective cleaning.
  3. Clear the blockage first; Warthogs (and all nozzles) are not as powerful under water.
  4. For root cutting, go past the roots and use your rear jets to cut. The rear jets are more powerful and there are two of them so the roots get hit two times per rotation.
