How To Use Your Pressure Washer
On the end of your spray gun is a nozzle that you can
twist from side to side. With the adjustable nozzle you
can adjust the nozzln.to either high pressure or low
pressure.
• Turn the nozzle in a counter clockwise direction to
achieve low pressure. Turn nozzle clockwise for high
pressure.
• For most effective cleaning, keep spray nozzle
between 8 and 24 inches of cleaning surface.
IMPORTANT; If you get spray nozzle too close,
especially on high pressure, you may damage the
cleaning surface.
• The pressure control knob Is located on the pump.
You can increase the pressure by turning the knob
clockwise or decrease the pressure by turning the
knob counterclockwise.
NOTE: The first step involves applying an appropriate
soap/chemical solution to penetrate and loosen grime.
The soap/chemical applied at low pressure to avoid
splashing, over spray and waste. Leave the solution
on surface for 3 to 5 minutes to allow solution to work.
NOTE: The second step involves cleaning the surface
you have prepared with the pressure washer and then
rinsing it clean.
• Turn the adjustable nozzle counter clockwise to low
pressure mode. Soap/chemicals cannot be applied
with nozzle in high pressure position.
• Review the use of the adjustable nozzle.
• Connect garden hose to water inlet (see ’To Start Your
Pressure Washer”), check that high pressure hose is
connected to spray gun and pump (see Assembly),
and start engine.
• Apply soap/chemicals to dry surface, starting
bottom and working up.
• Allow the soap/chemicals to soak in between 3-5
minutes before washing and rinsing.
• For cleaning, start at lower portion of area to be
washed and work upward, using long, even over
lapping strokes.
Your pressure washer is equipped with a chemical
injector adjustment knob. With the knob fully opened
you will get a 7 to 1 water to chemical ratio. With knob
fully closed you will get no chemical draw. Turn knob in
counterclockwise direction to achieve more chemical
draw and clockwise for less chemical draw.
NOTE: The maximum pressure for the unit is factory
adjusted. Do not attempt to adjust beyond this factory
setting.
Using Soaps/Chemicals
IMPORTANT: Use soaps and chemicals that are
designed specifically for use with pressure washers, to
apply soap/chemicals follow these steps:
• Prepare the soap/chemical as required by your job.
•

BEFORE STARTING THE ENGINE
To operate the engine you will need to do the following.
A CAUTION: Always check engine oil level before
every start. Running engine low of oil or out of oil
could result in serious damage.
A CAUTION: Always check pump oil level before
every start. Running pump low on oil could result
in pump damage.
Adding Pump Oil
Before running the high pressure washer, check the
pump oil level by viewing the sight glass on the side of
the pump. When properly filled, the oil will be at the
half way point marked by the two triangles. Your
pressure washer pump is shipped with oil. Add oil only
if oil level is lower than the half way point on the sight
glass. Do not overfill. Use 30 weight non-detergent oil
If necessary.
A CAUTION: Do Not use engine oil that has been
shipped with your unit in your pump. Engine oil is
detergent and your pump uses a non-detergent oil
Detergent oil can cause damage to your pump.
ftTAHUMG TCMPSaATURE WnCtWTED SEFORC NEXT OtL CHWtQE
Air cooled engines run hotter than automotive engines.
The use of multi-viscosity oil such as {10W-30, etc.) in
ambient temperatures above 40“F (4*C) wilt result in
higher than normal oil consumption. If multi-viscosity
oil is used, check the oil level more frequently to
prevent any posssible engine damage due to lack of
lubrication.Use of SAE30 oil below 40“F (4*C) wilt result
in hard starting and possible engine damage due to
inadequate lubrication.
Gasoline
Your pressure washer engine is 4 cycle. Use unleaded
fuel only.
A CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
A WARNING: Never fill fuel tank indoors. Never
fill fuel tank when engine Is running or hot. Do
not smoke or have open flame when filling fuel
tank.
Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Do not mix oil with gasoline.
If unleaded fuel is not available, leaded fuel may be
used-
IMPORTANT: it is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter hose or tank during storage. Also,
experience indicates that alcohol-blended fuels (called
gasoho! or using ethanol or methanol) can attract mois
ture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30
days or longer. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may
occur.
NOTE: Never start pressure washer without water
source turned on and connected to pressure washer.
To Start Your Pressure Washer
Make sure fuel shutoff valve is turned to the open
position.
CLOSED
OPENED
Squeeze trigger on pressure washer wand to relieve air
pressure caused by turning on the water. Water will
spew out of the gun in a thin stream. This will make it
easier to start the engine.
Engage the safety latch on the spray gun. This locks
the trigger in place and keeps you from accidentally
spraying a high pressure stream.
On the engine there is a choke/run lever. Place lever
to the choke position.
CHOKE
LEVER
• Remove gas cap
• Add unleaded gasoline, slowly, to fuel tank.
• Do not overfill.
Connect garden hose to the water inlet on the
pressure washer. Tighten by turning water inlet
counterclockwise.
