1. PulseJet will produce a consistent, fast, and tight oil pulse if the line is well primed, the dispenser needle is not clogged, and a recommended oil is being used.
2. To always keep the line well primed:
- Place the reservoir assembly near or above the spindle elevation
- never let the tank run completely dry
3. If you suspect that the dispenser needle is clogged, replace it. To do this, unscrew the knurled nozzle cap from the nozzle and gently twist and pull the yellow base of the needle off of the nozzle.
Note: This will expose the small check valve spring, do not lose it. Firmly press the replacement needle onto the nozzle taper. Re-install the nozzle cap finger tight.
4. Use recommended oil: light viscosity oils and tapping or cutting fluids work the best. Heavy viscosity oils such as motor oil, gear oil, or heavy tapping oils may not produce a high-quality stream.
5. If the oil line does get air bubbles inside, the pump inside the PulseJet nozzle will pass them through the system. While bubbles are moving through the nozzle, the stream will appear weak, aerated, and inconsistent. After the bubbles pass through, the stream will return to its proper form.
6. Always make sure the reservoir cap is installed and tightened when running PulseJet to maintain the proper tank pressure.
