Pressure Washer Rinsing
WARNING! Be extremely careful if you must
use the pressure washer from a ladder,
scaffolding or any other unstable location.
Pressure in a running washer builds as you
climb. When you press the trigger, the initial
spray recoil could cause you to fall. The high
pressure spray could also cause you to fall if
you are too close to the cleaning surface.
For Rinsing:
 Slide nozzle backward to high pressure and wait for
detergent to clear.
 Keep the spray gun a safe distance from the area
you plan to spray.
 Apply a high pressure spray to a small area and
then check the surface for damage. If no damage is
found, you can assume it is okay to continue
cleaning.
 Start at top of area to be rinsed, working down with
same overlapping strokes as you used for cleaning.
NOTE: You can also stop detergent from flowing by
simply removing siphon from bottle.
Automatic Cool Down System
(also known as Thermal Relief)
If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray
gun, circulating water in the pump can reach a
temperature between 140145°F. When the water
reaches this temperature, the automatic cool down
system engages and cools the pump by discharging
the warm water onto the ground. This system
prevents internal damage to the pump.

PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before
using it. Check for cuts, leaks, abrasions or bulging of
cover, damage or movement of couplings. If any of
these conditions exist, replace the hose immediately.
DANGER! Water spraying from a leak is
capable of injecting material into skin. Inspect
hose each time before using it. Never repair a
high pressure hose. Replace it with another
hose that exceeds the maximum pressure
rating of your pressure washer.
Check Chemical Injection Tube
Examine the filter on the detergent hose and clean if
clogged. The tube should fit tightly on the barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.
Check Gun and Adjustable Nozzle
Extension
Examine the hose connection to the spray gun and
make sure it is secure. Test the trigger by pressing it
and making sure it springs back into place when you
release it. Put the safety latch in the On position and
test the trigger. You should not be able to press the
trigger.
Check In-Line Filter
