OPERATION: SPRAY NOZZLE USAGE
sThis pressure washer comes with a stainless
steel wand, its tip has a quick connect coupler
to fit different nozzles.
sThe spray pattern is adjusted by installing the
appropriate spray pattern nozzle to the quick
connect coupler. Five nozzles are included, 0°,
15°, 25°, 40° and a detergent nozzle.
sTo install a nozzle to the quick connect
coupler, pull the coupler ring backwards and
insert the desired nozzle, release the coupler
ring to lock it in place.

sDetergent (black) - This nozzle must be used in conjunction with a cleaning detergent at low
pressure. Only use this nozzle when using a detergent or cleaning solution.
ADJUSTING WATER PRESSURE:
sThe water pressure is regulated by the throttle
lever.
sMoving the throttle lever towards the left will
increase the engine speed thus increasing the
water pressure.
sMoving the throttle lever towards the right will
decrease the engine speed thus decreasing
the water pressure.
DETERGENT INJECTOR (LOW PRESSURE):
sThis pressure washer is intended for use with pressure washer detergents only.
sDo not use powdered soaps which clog the injection system.
sFollow the detergent manufacturer’s directions if you have any questions or concerns.

HOW TO USE DETERGENT WITH PRESSURE WASHER:
1) Ensure detergent siphon tubes are set up correctly. You may want to refer to assembly
instruction #8 on page 10 to verify that siphon tubes are set up properly.
2) Pour the two kinds of detergents into the detergent tanks. It is recommend to have one detergent
tank filled with All-Purpose detergent, and the other filled with a more specific cleaning detergent.

3) The indicator on the detergent dial shows the amount and the consumption of detergent(A).
4) When using a detergent, the stainless steel wand must be fitted with the detergent nozzle
(black). See “OPERATION SPRAY NOZZLE USAGE” on page 13 for instructions on how to
connect detergent nozzle to wand.(B)
5) If the throttle lever is not in the fast position, the injection of the detergent may be decreased or
stopped completely, in this case, move the throttle lever towards the left to increase engine
speed and pressure.
Important Note: When you have finished using the detergent injector system, remove the
injector filter from the detergent container and place it in a different larger container
containing only clean water and let the pressure washer run until you no longer notice
detergent coming out of the wand. This will prevent detergent from gumming up the wand
and reducing pressure for next use.

USING THE PRESSURE WASHER TO CLEAN:
sSome cleaning jobs can be completed by using only water, but for most, it is advantageous to use
a detergent to penetrate and remove the dirt more effectively. When using pressure washer
approved detergent, make sure the surface to clean is dry. Wetting the surface first is not
recommended; it will dilute the detergent and will reduce the cleaning effectiveness.
sAvoid hot surfaces or direct sunlight; this will minimize the chances of the detergent
damaging the painted surface.
s$/./4 let the detergent dry or it may damage the painted surface. Allow the detergent to remain
on the surface for a short time before rinsing with clean water under high pressure.
sPosition the tip of the wand 6-8’ (15-20 cm) away from the surface to clean at a 45°angle.

ENGINE MAINTENACE:
Engine Oil Replacement
sEngine oil should be replaced after the first 20 hours of operation or after the first month of use.
sIt should be replaced every 100 hours or 6 months.
sTo replace engine oil; Loosen the oil gauge dipstick(A). Place an oil
pan underneath drain hex bolt(B), remove hex bolt and drain oil.
Once all the oil has completely drained, retighten the hex bolt.
Recommended Engine Oil 
sIt is recommended to use SAE10W-30 4-stroke gasoline engine oil.
sFill with clean engine oil through the oil gauge dipstick hole to recommended level.
Inspecting, Replacing or Cleaning Spark Plug 
sThe spark plug should be checked every 100 hours of operation or every 6 months.
To replace or clean spark plug:
1) Dismantle the spark plug wire(A) by pulling it off the spark plug(B).
Using the supplied spark plug wrench, undo the spark plug by turning
counter clockwise.
 
2) Check to see if there is carbon sediment build-up, if so, remove it.
If the carbon sediment is excessive, replace the spark plug.
3) Measure the electrodes clearance using a feeler gauge. The spark plug electrode clearance should
be between 0.7-0.8 mm. If the clearance exceeds 0.8 mm, replace the spark plug. The original spark
plug supplied is an LG F7RTC, you can replace it with an NGK BP6ES spark plug or equivalent.

4) Reinstall spark plug in the reverse order.
PRESSURE WASHER STORAGE:
-If you plan on storing your pressure washer for an extended period of time, the following
steps should be followed:
1) Add fuel stabilizer to fuel tank to minimize the formation of fuel gum deposits during storage.
2) Run engine at least 5 minutes after adding stabilizer to allow it to enter the fuel system.
NOTE: If a fuel stabilizer is not used, all gasoline must be drained from the tank and carburetor to
prevent gum deposits from forming on these parts and causing possible malfunction of the engine
(see instructions on draining fuel below).
3) Drain engine oil from engine as described in “Engine Oil Replacement.”
4) Pour approximately one teaspoon of engine oil through the spark plug hole and pull the recoil
starter slowly until you feel increased pressure which indicates the piston is on its compression
stroke and leave it in this position. This closes both the intake and exhaust valves to prevent
the inside of the cylinder from rusting.
5) Use pressure washer antifreeze to ensure that your pump will not freeze during the winter and
to keep components lubricated for maximum efficiency. See instructions below on (Preventing
Freezing Damage).
6) Cover the pressure washer and store it in a clean, well ventilated
and dry place. Ensure storage area is at room temperature.
*** See in-store to purchase fuel stabilizer or pressure washer antifreeze.
-If you wish to drain the fuel instead of adding fuel stabilizer, please follow these steps:
1) Turn fuel shut-off valve to the “OFF” position, remove drain hex. bolt (A)from the carburetor(B).
2) Now turn fuel shut-off valve to the “ON” position and drain the fuel from the tank, carburetor and
hose.
3) Reposition the carburetor drain hex bolt once the fuel is completely drained.
PREVENTING FREEZING DAMAGE:
sIf your pressure washer is subjected to freezing temperatures, damage could occur. This type of
damage is not covered under warranty. To avoid possible damage, a small amount of antifreeze
can be used.
sPlace the unit on its side with the water inlet facing upwards,
pour 1/4 cup of antifreeze into the water inlet.
sDisconnect spark plug wire, and then pull recoil starter several times to circulate the antifreeze in
the pump system. Reconnect spark plug wire.
sIt is also important to make sure the wand and all hoses are disconnected and drained of all water
or they may burst.
sWhen taking pressure washer out of storage, run water through the system until it runs clear.
