into consideration when positioning pressure washer.

How to Start Your Pressure Washer

To start your pressure washer for the first time,
follow these instructions step-by-step. This starting
information also applies if you have let the pressure
washer sit idle for at least a day.
1. Place pressure washer near an outside water

source capable of supplying water at a flow rate
greater than 11 L (3.0 GA) per minute and no
less than 1.4 BAR (20 PSI) at pressure washer
end of garden hose.

2. Check that high pressure hose is tightly

connected to spray gun and pump. See

illustrations.

3. Make sure unit is in a level position.
