OPERATING YOUR PRESSURE WASHER
1. HOW TO PRE-START PRESSURE WASHER
To start your pressure washer for the first time, follow these instructions. This
information also applies if you let the pressure washer sit idle for at least a day.
1.1 Place pressure washer near an outside water source capable of supplying
water at a flow rate at least 5 gallons/19L per minute and no less than 20 psi
at pressure washer end of garden hose.
1.2 Check all high-pressure hose connections are tightly connected to the pump,
valve, spray gun and Surface-Cleaner.
1.3 Make sure there are no kinks on hoses
1.4 Make sure the unit is in a levelled position.
2. ATTACHING HIGH-PRESSURE HOSE TO SPRAY-GUN
2.1 The spray gun is preassembled to a Swivel M22 Male Nipple or Male
Quick-Connect fitting (DWP-4000-H).
2.2 Connect the M22 female twist knob or Quick-Connect female fitting from
the high-pressure hose to the spray gun as shown by hand, make sure
it’s a tight fit and the threads are not cross threaded (the connection is a
self-sealed one, hence no plumbing is needed)
NOTE : newer models have Quick-connect fitting, which require no threads
