OpERATION

pRESSURE WASHER TERMINOLOGY

PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used
for air pressure, hydraulic pressure, etc.

GPM: Gallons per Minute. The unit of measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied by PSI equals CU.
Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is

not pulled. This feature allows the operator to release the trigger gun and reposition
themselves without having to turn the engine off in between cleaning actions.

11 - ENG

WARNING: Do not allow the unit to run for more than two minutes without
the gun trigger being pulled. This could cause overheating and damage to
the pump. When the temperature inside the pump rises too high, the thermal
relief valve will open and release a spray of water from the pump to lower the
internal temperature. The valve will then close.

Thermal Relief Valve (L, Fig. 5): When the temperature inside the
pump rises too high, this valve will open and release a gush of water
in an effort to lower the temperature inside the pump. The valve will

5

L

then close.
Detergent Injection System: Mixes cleaners or cleaning solvents with the water

to improve cleaning effectiveness.
Water Supply: All pressure washers must have a source of water. The minimum

requirements for a water supply are 20 PSI and 5 Gallons Per Minute. If your water
source is a well, the garden hose length can only be 30ft. (9m) max.

WARNING: To reduce the possibility of contamination always protect

against backflow when connected to a potable water system.

pRESSURE WASHER OpERATING FEATURES

pRESSURE ADJUSTMENTS

The pressure setting is preset at the factory to achieve op ti mum pres sure and
cleaning. If you need to lower the pres sure, it can be accomplished by these meth­ods.

1. Back away from the sur face to be cleaned. The further away you are, the

less the pressure will be on the surface to be cleaned.

2. Change to the 40˚ nozzle. This nozzle delivers a less powerful stream of water
and a wider spray pattern. Refer to How To Use Spray Wand.

NOTICE: DO NOT attempt to increase pump pressure. A higher pressure setting
than the factory set pressure may damage pump.

HOW TO USE SpRAY WAND

There are five spray pattern settings located on the 5n1 Multi-tip Nozzle. To select a
spray pattern, rotate the spray selector to the desired setting. Refer to the following
chart to choose the correct nozzle for the job to be performed.

DANGER: Risk of fluid injection. Do not direct discharge stream toward
persons, unprotected skin, eyes or any pets or animals. Serious injury will
occur.

WARNING: Flying objects could cause risk of serious injury. Do not attempt
to change nozzles while pressure washer is running. Turn engine off before
changing nozzles.

*NOTICE: The high pressure spray from your pressure washer is capable of
causing damage to surfaces such as wood, glass, automobile paint, auto striping
and trim, and delicate objects such as flowers and shrubs. Before spraying, check
the item to be cleaned to assure yourself that it is strong enough to resist damage
from the force of the spray.

HOW TO AppLY CHEMICALS/CLEANING SOLvENTS (FIG. 6)

Applying chemicals or cleaning solvents is a low pressure operation. NOTE: Use
only soaps and chemicals designed for pressure washer use. Do not use bleach.

To Apply Chemicals:

1. Ensure detergent siphon hose (F, Figure 6) is attached
tobarbed fitting location near high pressure hose

F

connection of pump as shown.

2. Place other end of detergent siphon hose with filter on
it into container holding chemical/cleaning solution.
NOTE: For every 7 gallons of water pumped 1 gallon
of chemical/cleaning solution will be used.

3. Select the SOAP setting on the 5n1 Multi-tip Nozzle,
see How To Use Spray Wand paragraph in this section.

4. After use of chemicals, place detergent siphon hose into container of clean
water and draw clean water through chemical injection system to rinse system

5. Connect water source (N) to pump inlet (J). NOTE: Water source must provide

a minimum of 5 gallons per minute at 20 PSI.

6. Connect high pressure hose (C) to pump outlet (I).

WARNING: To reduce the possibility of contamination always protect

against backflow when connected to a potable water system.

7. Choose the correct nozzle for the job to be performed. See How To Use spray
Wand instructions in this section. NOTE: If applying a chemical or cleaning

solution, see How To Apply Chemicals/Cleaning Solvents instructions in this
section.

8. Turn water source on.

NOTICE: Risk of property damage. Failure to do so could cause damage to the
pump.

9. Remove all air from the pump and high pressure hose by depressing trigger
until a steady stream of water is present.

10. Start engine. See Engine Owner's Manual for correct procedure.

WARNING: Risk of unsafe operation. If engine does not start after two
pulls, squeeze trigger of gun to relieve pump pressure. Pull starter cord slowly
until resistance is felt. Then pull cord rapidly to avoid kickback and prevent
hand or arm injury.

NOTE: If the oil level in the engine is low, the engine will not start. If the engine does
not start, check the oil level and add oil as needed.

WARNING: Risk of unsafe operation. Stand on a stable surface and
grip gun/spray wand firmly with both hands. Expect the gun to kick when
triggered.

12. Release trigger to stop water flow.

WARNING: Do not allow the unit to run for more than two minutes without
the gun trigger being pulled. This could cause overheating and damage to
the pump. When the temperature inside the pump rises too high, the thermal
relief valve will open and release a spray of water from the pump to lower the
internal temperature. The valve will then close.

WARNING: Risk of injury from spray. Always engage

10

the trigger lock (O) when gun is not in use. Failure to do so
could cause accidental spraying.

SHUTTING DOWN

1. After each use, if you have applied chemicals, place

WARNING: Risk of fire hazard. Always disconnect, spark plug wire,
let the engine cool and release all water pressure before performing any
maintenance or repair. The engine contains flammable fuel. Do not smoke or
work near open flames while performing maintenance.

To ensure efficient operation and longer life of your pressure washer, a routine
maintenance schedule should be prepared and followed. If the pressure washer is
used in unusual conditions, such as high-temperatures or dusty conditions, more
fre quent maintenance checks will be required.

ENGINE

Consult the Engine Owner's Manual for the man u fac tur er's recommendations
for any and all maintenance. NOTE: The engine drain plug is located at the rear of
the unit.

pUMp

The pump was filled with oil at the factory. The pump on this unit is maintenance
free and requires no oil. If there is a problem with the pump contact us at
www.simpsoncleaning.com

CONNECTIONS

Connections on pressure washer hoses, gun and spray wand should be cleaned
regularly and lubricated with light oil or lithium grease to prevent leakage and
damage to the o-rings.

NOzzLE CLEANING (FIG. 11)

If the nozzle becomes clogged with foreign materials, such as dirt, excessive

STORAGE

ENGINE

Consult the Engine Owner's Manual for manufacturer’s recommendations for
storage.

TO pREvENT FUEL-RELATED pROBLEMS

1. Add Ethanol Shield

er’s instructions. When adding a gasoline stabilizer, fill the fuel tank with fresh
gasoline. If only partially filled, air in the tank will promote fuel deterioration
during storage. If you keep a container of gasoline for refueling, be sure that it
contains only fresh gasoline.

2. After adding a gasoline stabilizer, run the engine outdoors for 10 minutes

to be sure that treated gasoline has replaced the untreated gasoline in the
carburetor.

3. Turn the fuel valve to the OFF position.

4. Continue to run the engine until it stops from the lack of fuel in the carburetor

fuel bowl. Running time should be less than 3 minutes.
