When using the dipstick to check oil level, DO NOT screw in
the dipstick while checking.
NOTICE
Check oil level often during the break-in period. Refer to the
Maintenance section for recommended service intervals.
CAUTION
This engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below the threshold
level.
NOTICE
We consider the first 5 hours of run time to be the break-
in period for the engine. During the break in period we
recommend using standard automotive non-synthetic blended
oils. After the break in period synthetic lubricant can be used
but is not required. Adjusting throttle setting will increase/
decrease engine speed helping to seat piston rings. Avoid
bogging or lugging the engine down and avoid prolonged
running at constant RPM. After the 5 hour break-in period,
change the oil. Using synthetic lubricants does not increase
the recommended oil change interval.

76503-N - 3100 PSI PRESSURE WASHER OPERATION
15
NOTICE
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not increase the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting
in cold ambient < 41º F (5º C) temperatures.
Add Fuel
Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 91 and an ethanol content of 10% or less by
volume. ybc
DO NOT mix oil with gasoline.
1. Remove the gasoline cap.
2. Slowly add gasoline to the tank. Tank is full when gasoline
reaches red circle on screen. DO NOT OVERFILL. Gasoline
can expand after filling. A minimum of ¼ in. (6.4 mm) of
space left in the tank is required for gasoline expansion,
although more than ¼ in. (6.4 mm) is recommended. Gasoline
can be forced out of the tank as a result of expansion if
overfilled, and can affect the stable running condition of the
pressure washer.
CAUTION
Use unleaded gasoline with a minimum octane rating of 91
and an ethanol content of 10% or less by volume.
DO NOT light cigarettes or smoke when filling the tank.
DO NOT mix oil and gasoline.
DO NOT overfill the tank. Fill tank to approximately ¼ in.
(6.4 mm) below the top of the tank to allow for gasoline
expansion.
DO NOT pump gasoline directly into the pressure washer at the
pump. Use an approved fuel container to transfer the gasoline
to the pressure washer.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
WARNING
Pouring gasoline too fast through the fuel screen may result in
gasoline splashing over the operator while filling.
NOTICE
The engine works well with 10% or less ethanol blend
gasoline. When using ethanol-gasoline blends there are some
issues worth noting:
–Ethanol-gasoline blends can absorb more water than
gasoline alone.
–These blends can eventually separate, leaving water or
a watery goo in the tank, fuel valve and carburetor. The
compromised gasoline can be drawn into the carburetor
and cause damage to the engine and/or potential hazards.
–If a fuel stabilizer is used, confirm that it is formulated to
work with ethanol-gasoline blends.
–Any damages or hazards caused by using improper
gasoline, improperly stored gasoline, and/or improperly
formulated stabilizers, are not covered by manufacturer’s
warranty.
It is advisable to always shut off the gasoline supply and
run the engine to starvation after each use. See Storage
instructions for extended non-use.

starter. After second pull, move choke lever to the “RUN”
position for up to the next 3 pulls of the recoil starter. To much
choke leads to spark plug fouling/engine flooding due to the
lack of incoming air. This will cause the engine not to start.
NOTICE
If the engine does not start after 2 pulls, relieve pump pressure
by pulling the trigger on the trigger gun.
NOTICE
If the engine starts but does not run make certain that the
pressure washer is on a flat, level surface. The engine is
equipped with a low oil sensor that will prevent the engine
from running when the oil level falls below a critical threshold.
Distance from Cleaning Surface
The distance between the spray nozzle and the cleaning surface is
another factor that affects the impact force of the water.
The impact force of the water increases as the nozzle is moved
closer to the surface. You can vary the impact force by controlling
–The nozzle’s fan pattern.
–The nozzle’s angle to the cleaning surface.
–The nozzle’s distance from the cleaning surface.
Never use a narrow high impact stream on a surface that is
susceptible to damage. Avoid spraying windows with a narrow
high impact stream or turbo nozzle. Doing so may break the glass.
1. Before triggering the gun, select a nozzle with a wide fan
pattern.
2. Place the nozzle approximately 4-5 ft. (1.2 m - 1.5 m) away
from the cleaning surface. Then hold the nozzle at a 45
degree angle to the cleaning surface. Trigger the gun.
3. Vary the fan pattern spray angle and the distance to the
cleaning surface until optimum cleaning efficiency is achieved
without damaging the surface.

High Pressure Wash
CAUTION
Always engage the trigger safety latch when the unit is not in
use.
The trigger safety latch prevents the gun from being triggered
accidentally. Push the latch fully down to engage it.
WARNING
Injection hazard.
Fully unwrap and straighten high pressure hose prior to and
during each use and do not allow it to become kinked. The
high pressure hose features an outer covering that provides
strength to the hose. If the outer covering becomes damaged,
stop using the hose and replace it immediately. A kinked or
damaged hose can develop a high pressure leak and result in a
possible injection or other serious personal injury.
NOTICE
If the starter grip and rope becomes difficult to pull, squeeze
the trigger to relieve water pressure before attempting to start
the engine again.
For high pressure cleaning, refer to the Nozzle Selection Guide for
more information about which quick connect nozzle to choose.
CAUTION
The narrow high impact spray can damage some surfaces.
A wide fan pattern distributes the impact of the water over a larger
area resulting in excellent cleaning action with reduced risk of
surface damage. Clean large surface areas quickly using a wide
fan pattern.
Low Pressure Wash
Detergent Use
The use of detergents can dramatically reduce cleaning time
and assist in the removal of difficult stains. Many detergents are
customized for pressure washer use on specific cleaning tasks.
Pressure washer detergents are as thick as water.
Using thicker detergents – like dish soap – will clog the chemical
injection system.
NOTICE
Use only detergents designed for pressure washers.
Do not use household detergents, acids, alkalines, bleaches,
solvents, flammable material, or industrial grade solutions,
which can damage the pump or cause property damage. Many
detergents may require mixing prior to use. Prepare cleaning
solution as instructed on the solution bottle. Always test in an
inconspicuous area before beginning.
You can effectively clean surfaces by combining the chemical
action of detergents with high pressure rinses. On vertical
surfaces, apply the detergent starting at the bottom and work
your way upward. This method prevents the detergent from sliding
down and causing streaks. Begin high pressure rinsing at the
bottom and work your way upward. On particularly tough stains,
use a brush in combination with detergents and high pressure
rinsing.
1. Fill the detergent tank with cleaning solution.
NOTICE
The trigger gun will only draw detergent from the tank when
the black quick connect nozzle is installed in the wand.
NOTICE
When spraying detergent, the detergent will be diluted 1:12.
Approximately 20.3 oz. (0.6 L) of detergent will be consumed
from the tank for every minute sprayed.
System Flush
After using detergents, flush the suction system by placing the
detergent suction tube into a bucket of clean water.
WARNING
NEVER turn the water supply off before turning the engine off.

Depressurize System
To depressurize, turn engine off, turn water supply off and squeeze
gun trigger for at least 15 seconds after engine is turned off.
WARNING
NEVER disconnect the high pressure discharge hose from the
machine while the system is pressurized.
To reduce the risk of bodily injury or property damage, always
follow this procedure whenever spraying is stopped, when work
is completed, and before checking or repairing any part of the
system.
1. Engage the trigger gun lock out.
2. Turn the unit off.
3. Shut off the water supply.
4. Disengage the trigger safety latch and trigger the gun to
relieve pressure.
5. Re-engage the trigger safety latch.
6. Before overnight storage, long term storage, or transporting
unit, disconnect the water supply and turn off the fuel supply
valve.
Operating Tips
CAUTION
Never operate your pressure washer without water.
CAUTION
Never connect your pressure washer to a hot water supply.
Connecting your pressure washer to a hot water source will
significantly reduce the life of the pump and will void the
warranty.
CAUTION
Running the unit for more than one minute without spraying
water causes heat to build up in the pump.
In the event that the pump gets too hot, a thermal relief valve
will open to release the hot water. Running the unit without
spraying water can damage pump components and will void
the warranty.
Stopping the Engine
1. Turn the fuel valve to the “OFF” position.
2. Let the engine run until fuel starvation has stopped the
engine. This usually takes a few minutes.
3. Press the engine switch to the “OFF” position.
4. Depressurize system.
5. Turn off water supply and unplug all hoses. Never start or
stop the pressure washer unless the water supply is turned
on.
Important: Always ensure that the fuel valve and the engine
switch are in the “OFF” position when the engine is not in use.
NOTICE
If the engine will not be used for a period of two (2) weeks or
longer, please see the Storage section for proper engine and
fuel storage.
Operation at High Altitude
The density of air at high altitudes is lower than at sea level.
Engine power is reduced as the air mass and air-fuel ratio
decrease. Engine power and output will be reduced approximately
3½% for every 1000 ft. of elevation above sea level. At high
altitudes increased exhaust emissions can also result due to the
increased enrichment of the air fuel ratio. Other high altitude
issues can include hard starting, increased fuel consumption and
spark plug fouling.
To alleviate high altitude issues other than the natural power
loss, CPE can provide a high altitude carburetor main jet. The
alternative main jet and installation instructions can be obtained
by contacting our Technical Support Team. Installation instructions
are also available in the Technical Bulletin area of the CPE website.
The part number and recommended minimum altitude for the
application of the high altitude carburetor main jet is listed in the
following table.
In order to select the correct high altitude main jet it is necessary
to identify the carburetor model. For this purpose, a code is
stamped on the side of the carburetor. Select the correct high

76503-N - 3100 PSI PRESSURE WASHER MAINTENANCE

altitude jet part number corresponding to the carburetor code
found on your particular carburetor.
Carb. Code High Alt. Jet Part Number Min. Altitude
P19-1-H 26.131017.00.01.H 3,500 ft.
(1,067 m)
WARNING
Operation using the alternative main jet at elevations lower
than the recommended minimum altitude can damage the
engine. For operation at lower elevations, the originally
supplied standard main jet must be used. Operating the
engine with the wrong engine configuration at a given altitude
may increase its emissions and decrease fuel efficiency and
performance.
MAINTENANCE
Make certain that the pressure washer is kept clean and stored
properly. Only operate the unit on a flat, level surface in a clean,
dry operating environment. DO NOT expose the unit to extreme
conditions, excessive dust, dirt, moisture or corrosive vapors.
WARNING
Never operate a damaged or defective pressure washer.
WARNING
Improper maintenance will void your warranty.
NOTICE
