First, make sure the pump is in proper working condition, i.e. gas, and oil levels, parts intact, etc. *Use 30 wt. Detergent Oil in engine and Gear Reduction. *Use Unleaded gasoline in Engine.

Connect inlet hose. Unit may be suction, gravity, or force fed.

Connect 8 foot outlet hose to the outlet piping. Performing a simulated test: will allow you to preset your test pressure and ensure working performance of test unit. To simulate a test on your unit connect a ball valve to the end of your outlet hose. The outlet hose will be your simulated test environment.

Open the outlet ball valve. If you are doing a simulated test or adjusting pressure regulator open ball valve at the end of outlet hose, also.

Start the engine.

Open the hose bib located below pressure gauge, releasing air from the piping and unit. Close this valve when water flows freely.

Allow pressure to build. For simulated testing or pressure regulator adjustment close ball valve on the end of outlet hose. If unit does not build pressure or a drop in pressure occurs; check for leaks, bleed air from system, consult manufacturer’s complete operating instructions for troubleshooting.

Adjust the T-Handle Pressure regulator to set the required test pressure. Clockwise to INCREASE pressure or counterclockwise to DECREASE pressure. Bleed air in between each adjustment.

Once pressure is met, and the air is bled from the system, close the ball valve on the unit, and shut off the engine, SIMULTANEOUSLY. Allow the test pump and the tested line to sit, holding pressure for your required test time.
