The Warthog nozzle (previously known as Blizzard) is one of the best known and most popular nozzles in the industry. It easily removes grease and ice, cuts roots and deals with all other kinds of stubborn blockages. The Warthog is hydraulically braked, creating a very powerful jet for unclogging, cleaning or descaling. The Warthog is suitable for different pipe diameters with a range of accessories that centralise the nozzle in the pipe.

Proper maintenance will extend the life of your nozzle

We can’t say it enough - correct and regular maintenance will help extend the life of your equipment and accessories including the Warthog nozzle. To help you maximise the life of your Warthog, we’ve compiled this checklist of key maintenance points.

Checking the oil level

As the Warthog is hydraulically braked, oil is present in the nozzle. In order to guarantee optimal operation, it is important that the oil level is checked regularly. If the nozzle rotates too fast, the oil level is probably too low or water has entered the oil reservoir. You can easily check the oil level yourself following these steps:

  1. Hold the nozzle vertically, with the front of the nozzle pointing down (As shown in the diagram below).

  2. Open the screw with a flat screwdriver. The oil is not pressurized in the nozzle, so you can simply unscrew the fixing.

  3. Check the oil level. When the oil level is just below the screw thread it is sufficient.

  4. If necessary, top up the oil using the syringe. Push the oil from the syringe into the reservoir. When oil comes out through the inlet section, the reservoir is filled. If the liquid that comes out is dirty or watery, keep adding fresh oil until clean liquid comes out.

  5. Close the oil reservoir by replacing the slotted screw. Make sure to tighten the screw so that the oil reservoir does not leak.

Changing the oil

IChanging the oiln addition to checking the oil level, from time to time it’s also necessary to change the oil completely. For example, when the oil in the reservoir has become dirty, or after about 100 operating hours. You can easily do this yourself following these steps:

  1. Hold the nozzle vertically, with the front of the nozzle pointing down (As shown in the diagram below).

  2. Open the screw with a flat screwdriver. The oil is not pressurized in the nozzle, so you can simply unscrew the fixing.

  3. Pour any old oil from the nozzle and discard it safely.

  4. Wipe all parts clean.

  5. Fill the reservoir with fresh oil using the syringe. Push the oil from the syringe into the reservoir. When oil comes out through the inlet section, the reservoir is filled.

  6. Close the oil reservoir by replacing the slotted screw. Make sure to tighten the screw so that the oil reservoir does not leak.

 

Cleaning rotating parts

In order to achieve optimal results, it is important that the rotating parts move freely and do not get stuck. If the nozzle is dirty, it can block and prevent water from passing through. You can easily solve this yourself following these steps:

    1. Firstly, try gently rotating the nozzle by hand. If this is difficult and feels rough, the spray head probably needs to be repaired. The bearings or seals are likely to be worn out and need to be replaced. Always have repairs carried out by an approved company.

    If you can rotate the nozzle without problems, but little or no water comes through the nozzle, there is probably a blockage in one of the jets.

    1. Disconnect the nozzle from the high pressure hose and check all nozzle holes. Even if only one jet is clogged, this can stop the entire nozzle from rotating.

    2. Remove the jets from the nozzle and clean them thoroughly. There is no point in pushing dirt back into the jet. This will cause the blockage to cause problems again at a later time.

    3. When all jets have been cleaned, place them back into the nozzle. You can now use the nozzle again.
