MAINTENANCE
WATER FILTER AND NOZZLE CLEANING INSTRUCTIONS
A clogged or partially clogged water filter or nozzle can cause significant reduction
of water pressure coming out of the nozzle and/or cause the unit to pulsate while
spraying.
1. The water filter was installed inside the water inlet quick connector, should be
cleaned periodically. Rinse it with clean tap water, and then place it back into the
water inlet quick connector.
2. Using the nozzle tip cleaner provided (or an unfolded paper clip), insert the wire
into the nozzle hole and move back and forth until debris is dislodged. Back flush
water through the nozzles using garden hose and highest pressure available (either
standard water nozzle or use your thumb over the nozzle to create water pressure
for back flush).
STORAGE
Do not store pressure washer outdoors and store the pressure cleaner, parts, and-
accessories in an area with a temperature above 32°F (0°C).
Do not store pressure washer where it might freeze while there's water inside the
machine.
Serious damage will occur to the water system, pump and / or motor.

TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE WASHER
1. Never operate machine without water.
2. Pressure washer is not meant to pump hot water. Never connect to hot water
supply this will significantly reduce life of the pump.
3. Using detergent other than those formulated for pressure washers may cause
damage to pump components (o-rings,etc.).This also applies to chemicals such as
bleach, dish soap, etc.
4. Never operate unit for more than one minute without spraying water. Resulting
heat buildup will damage pump.
TROUBLESHOOTING
PROBLEM SOLUTION
Unit will not turn on. Make sure the power washer is in the “OFF” position. Plug in the electrical
cord to a grounded 120 volt outlet (no electrical extension cord should be
used). If the electrical cord will not plug into your outlet, your electrical
outlet is not properly grounded and should not be used. Use another
electrical outlet. Press the reset button on GFCI power box. If the colour of
red is not visible in the little window on the GFCI, unplug and plug in again.
Press reset, and look for the red colour in the window, this should remain
red in colour. If the colour is staying red, turn the power switch on the power
washer to “ON”. Squeeze the trigger on the spray gun and try again. If this
did not correct the problem, try plugging into another electrical outlet and
repeat the above procedure.
The high pressure (HP)
hose will not connect/
stay connected to the
spray gun. Is this a spray
gun problem?
In most cases, the spray gun is not the problem. The problem is the rubber
sleeve covering the fitting at the end of the high pressure hose. It has likely
slipped up toward the metal tip. The fix: wiggle, twist and/or pull the rubber
sleeve down until the entire tip is visible plus an 1/8” of the metal fitting
below the tip. Now try to insert the hose tip into the spray gun. It should
“click”into place and will not come out until the hose is released by pushing
in the lever on the underside of the gun. You may cut away the end of the
sleeve with a sharp knife if unable to move the sleeve down. Be careful not
to cut or puncture the hose.
The unit is running but
there is no water flow.
Check the water source. Unclog the nozzle on the lance (See nozzle
cleaning instructions under “Cleaning nozzles”). Or take o the lance and
just spray out of the spray gun. This will indicate what the problem is with
the lance.
Why is water leaking
where the high pressure
hose connects to the
spray gun?
Make sure there is an O-ring at the end of the metal tip of the high pressure
hose. If no O-ring is present, the connection between the hose and spray
gun will leak.
I can’t remove the lance
from the spray gun.
What should I do?
All lances and detergent tank are attached and removed from the spray
gun in the same manner. Insert the quick-release end of the lance together
(about a 1/8”) and turn clockwise. The lance will lock in place. Remove the
lance by reversing this procedure. Press the spray gun and lance together
and turn counterclockwise. The lance will slide out. Or, hold the spray gun
and lance in an upright position with the nozzle end on the floor. Push the
whole assembly straight down to loosen the connection, and then follow the
removal process again. You may also spray soapy water or a lubricant in the
area where the lance connects to the spray gun.

15
The power washer turns
on for 2 seconds, shuts
o,and will not turn
back on. Do I have a
defective unit?
It sounds like your power washer is working just fine. When the water is
connected, the accessories are assembled properly, and the power switch
is turned on, the power washer may turn on for 1-2 seconds to prime the
pump. It automatically shuts o and waits for the spray gun trigger to be
pressed. When the trigger is pressed, water starts flowing through the
pump. The water sensor in the pump “senses” the moving water and
automatically turns the power washer on. Or, turn the power switch to o,
hold in the trigger on the spray gun, so that you have a steady stream of
water. While you are holding the trigger open on the spray gun, at the same
time, turn the power switch on.
