How do I get high pressure?
• Useanycolortipexceptblack.Theblacktipisonlyusedforlowpressuredetergentapplication.
How do I get the soap suction to work?
1. Connect the clear plastic chemical suction tube to the plastic hose barb on pump, insert the other end into your detergent.
2. Install the black spray tip to apply low pressure detergent.
Why doesn’t the pressure washer apply detergents with high pressure?
Detergents “bounce” off cleaning surfaces as fast as they are applied. The pressure washer’s features allow for a detergent to be
drawn while in low pressure mode only. By applying detergent at low pressure, the effect of “bouncing” is reduced. Also, detergents
are only effective when time is allowed for them to work on the surface of whatever is being cleaned. After applying the detergent,
wait 1-3 minutes while it works, and then proceed to rinse the surface with high pressure.
What maintenance do I need to perform on my pressure washer?
1. After turning off the pressure washer and the water, depressurize the hose by triggering the gun.
2. Remove the garden hose and high pressure hose from the pump.
3. Turn the motor on for 5 seconds to purge water from the pump. This will help protect the pump from damage.
4. Do not store your pressure washer in an area where the temperature will drop below 32˚ F.
5. Follow proper storage and winterizing instructions found on pages 13 and 14.

Operating Instructions and Parts Manual
Glossary
Become familiar with these terms before operating the unit.
CAVITATION - The shock of thousands of bubbles collapsing inside the pump
quickly, pitting metal surfaces and seals. Cavitation is caused by lack of water at
the inlet of the pump.
CHEMICAL INJECTOR - A chemical injector allows the chemical or soap to be
injected into the water stream, making cleaning faster and easier than water
alone.
DETERGENT INJECTION SYSTEM - Cleaning detergents are drawn into the
water stream making cleaning more effective by allowing detergents to saturate
the soiled surface.
GPM (GALLONS PER MINUTE) - More water per minute can mean faster
cleaning, especially when washing off materials like mud and road tar.
GFCI (GROUND FAULT CURRENT INTERRUPTER) - GFCI protects user from
accidental electrocution (for electric powered pressure washers only).
HIGH PRESSURE OUTLET - A connection for high pressure hose.
HP (HORSEPOWER) - A unit of measure for work.
NOZZLE (QUICK CONNECT SPRAY TIPS) - The nozzle is the restriction at the
end of the wand that creates the pressure. Nozzles have different spray patterns
that can affect the width and strength of the spray. The 40-degree (white) nozzle
delivers a flat spray of about 40-degrees. There’s also a 25-degree (green) and the
most popular 15-degree (yellow) nozzles. The 0-degree (red) nozzle should be
used with caution, it can cut into wood and cause damage.
PSI (POUNDS PER SQUARE INCH) - A unit of measure for pressure. It
determines how much pressure is directly applied on the surface being cleaned.
The pressure that is delivered by the pressure washer is directly responsible for
breaking the bond between the debris and the surface being cleaned.
THERMAL RELIEF - A technique used to reduce the build-up of high
temperature water within a pressure washer pump caused when the spray gun
trigger is closed. This system prevents internal pump damage by cycling water
through pump when water reaches maximum water temperature. Warm water
will discharge from pump onto ground.
Figure 3 - Chemical Injector
115 Volt 230 Volt
Figure 4 - GFCI Outlet
Figure 5 - High Pressure Outlet
UNLOADER - A device used to relieve the water pressure within the pump
whenever the spray flow is blocked. It allows the motor to continue running
when the operator releases the trigger on the spray gun and stops washing. It
diverts the pressure, that would build up without the unloader, by taking the
water from the exit side of the pump and loops it back to the inlet side in a
continuous “bypass” mode. The unloader will return the flow of water to the
spray gun when the operator presses the trigger.

Operation
SURFACE PREPARATION
The following cleaning procedure will help you organize your cleaning task and
ensures that you will achieve the best results in the shortest amount of time.
Remember to use the spraying / cleaning techniques mentioned in the following
section.
Before starting a pressure washer cleaning job, prepare the surface you intend to clean.
Clear furniture from the area and make sure that all windows and doors are closed
tightly. Also, protect all plants and trees near the cleaning area with a drop cloth. A
covering ensures that your plants won’t be sprayed by the detergents.
Models CP5211, CP5216 and CP5321
Figure 17 - Trigger unlockedFigure 16 - Trigger locked
START UP
ALWAYS use this start up procedure to ensure that the unit is started safely and
properly.
If water has frozen in the pressure washer, thaw the pressure washer in a
warm room before starting. DO NOT pour hot water on or into the pump;
internal parts will be damaged.
1. Ensure that the power switch is in the “OFF” position.
2. Attach a garden hose to the inlet side of the pump and connect it to the water
supply. Use a hose with an internal diameter (I.D.) of 5/8 in. (1.58 cm) and a length
of 50 ft. (15 m) or less.
Some local plumbing codes require backflow prevention when
connecting to a fresh water supply. Install a backflow preventer upstream
from the pump if necessary.
a. If inlet water pressure is over 100 psi, install a regulating water valve at the
garden hose connection.
b. Do not exceed 100˚ F (38˚ C) inlet water temperature.
NOTE: The inlet water supply must have a minimum flow rate of 5 gpm (19 lpm).
3. Turn the water supply ON.
Never run the unit dry. Be sure the water supply is completely turned on
before operating the unit.
4. Trigger the gun until water sprays from the tip indicating that all air is purged from
the system. Set the trigger safety latch.
5. Plug the power cord into a grounded 120V outlet, that is on a dedicated circuit.
Press the reset button on the GFCI plug adapter. This must be done each time the
unit is plugged into an outlet.

Operating Instructions and Parts Manual
Operation (Continued)
INITIAL HIGH PRESSURE RINSE
Spray the cleaning surface with water to clear off any dirt or grime that may have
collected on the surface. Doing so allows the detergent to attack the deep down dirt
that has worked its way into the cleaning surface.
Trigger the gun 3 to 5 times to get any trapped air out of the system.
Adjusting the Spray Fan Angle
Two quick connect tips for Model CP5216 or five quick connect tips for Models CP5211
and CP5321 are included with this pressure washer. The tips have a range of spray fan
angles, ranging from 0°, narrow high impact, to a 65° wide fan spray.
Pressure can also be adjusted by moving closer or further away from the cleaning
surface and by adjusting the spray fan angle as shown.
Angle to the Cleaning Surface
When spraying water against a surface, you can generate maximum impact by striking
the surface head on. However, this type of impact can cause dirt particles to embed in
the surface and can prevent the desired cleaning action.
The optimum angle for spraying water against a cleaning surface is 45 degrees.
Spray water against a surface at a 45 degree angle to achieve the most beneficial impact
force and to efficiently remove debris.
Distance From Cleaning Surface
The distance between the spray tip and the cleaning surface is another factor that
affects the impact force of the water. The impact force of the water increases as the tip
is moved closer to the surface.
Counterclockwise:
Lower pressure
Clockwise:
Higher pressure
Figure 18 - Pressure adjustment for Model
CP5216
Figure 19 - Narrow high impact stream
How to Avoid Damaging Surfaces
Damage to cleaning surfaces occurs because the impact force of the water exceeds
the durability of the surface. You can vary the impact force by controlling the spray
tip angle to the cleaning surface and the distance from the cleaning surface and by
changing the spray tip. NEVER use a narrow high impact stream on a surface that is
susceptible to damage. Avoid spraying windows with a narrow high impact stream.
Doing so may break the window. The most sure way to avoid damaging surfaces is to
follow these steps:
1. Before triggering the gun, make sure the quick connect tip you are using is
appropriate for the application.
2. Place the spray tip approximately 4-5 feet (1,22-1,52 m) away from the cleaning
surface. Then hold the lance and spray tip 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.
DETERGENT APPLICATION
NOTE: Use only detergents formulated for pressure washers.Test detergent in an
inconspicuous area before use.
Detergents
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 and prevent the
application of the detergent.

Operation (Continued)
Models CP5211, CP5216 and CP5321
Once applied to a cleaning surface, detergents take time to
break down dirt and grime. Detergents work best when applied
at low pressure.
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. Follow manufacturer’s label directions for mixing correct
concentrations of soap/detergents. The soap detergent to
water ration through the pump is approximately 10% (1 to
10).
2. Insert the filter end of the clear plastic detergent tube into
the detergent container.
3. Use the black 65° quick connect spray tip.
4. Adjust the detergent injection flow by turning the collar of
the injector. Turning collar clockwise increases detergent
flow.
General Cleaning Tips
1. Apply the detergent so that it thoroughly covers the cleaning
surface. Apply the detergent from bottom to top to prevent
the detergent from sliding down and streaking. Wait a
couple of minutes for the detergent to break down the dirt
and grime. Use a brush to lightly scrub heavily soiled areas.
Never allow the detergent to dry on the cleaning surface.
2. To rinse: replace black 65° spray tip with another color tip.
Never replace quick connect tip when gun
is triggered. Always engage trigger lock on gun
before removing or installing quick connect tips.
3. After using detergents, flush the suction system by placing
the detergent suction tube into a bucket of clean water and
spraying with the black spray tip.

The easiest way to regulate the cleaning power of your pressure
washer is by changing the distance from the surface you are
cleaning. Begin spraying with a wide fan pattern while standing
several feet from the surface. Slowly move closer to the object
you are cleaning, adjusting the spray pattern as necessary, until
you find the most effective cleaning technique.
NOTE: The unit may have also a pressure adjustment knob on
the pump that can adjust the pressure.
FINAL RINSE
The final rinse should start at the bottom and work upward.
Make sure that you thoroughly rinse the surface and that you
remove all detergent.
PRESSURE RELIEF PROCEDURE
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 safety latch.
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. When checking or repairing unit, remove the wall outlet plug
from the wall.
7. Before overnight storage, long term storage, or transporting
unit, disconnect the water supply.
SHUTDOWN
1. Be sure all detergent is flushed from system.
2. Turn the motor OFF.
3 Turn the water supply OFF.
4. After the motor and water supply are turned off, trigger the
gun to depressurize the system.
NEVER turn the water supply off before turning
the engine/motor off. Serious damage could
occur to the pump and/or engine/motor.
NEVER disconnect the high pressure discharge
hose from the machine while the system is
pressurized. To depressurize, turn engine/motor off, turn water supply
off and squeeze gun trigger 2-3 times.
5. After each use, wipe all surfaces of the pressure washer with a
clean, damp cloth.
STORAGE
• Donotstorethepressurewasheroutdoors.
• Donotstorethepressurewasherwhereitmightfreezeunless
it has been properly winterized.
Winterizing Instructions
1. Disconnect the high pressure hose from the pump.
2. Insert a 12 inch to 14 inch piece of garden hose into the
pump inlet.
3. Place a funnel in the other end of the garden hose.
Read the manufacturer’s instructions for safe
handling and disposal of RV antifreeze.
4. Pour approximately 6 oz. of RV antifreeze into the funnel.
5. Jog the On/Off Switch briefly until the RV antifreeze comes
out of the pump outlet.

6. Disconnect the high pressure hose from the gun and drain the hose. Hold the gun
and lance in a vertical position and squeeze the trigger to drain the water out.
TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE WASHER
1. Never operate the unit without water.
2. Your pressure washer is not meant to pump hot water. Never connect your pressure
washer to a hot water supply as it will significantly reduce the life of the pump.
3. Running the unit for more than one minute without spraying water causes heat to
build up in the pump. Running the unit without spraying water can damage pump
components.
Maintenance
Observe regular maintenance intervals to ensure maximum performance and life
from the pressure washer. Refer to the schedule for recommended maintenance. If you
operate the pressure washer in dusty conditions, perform maintenance checks more
often.
MAINTENANCE SCHEDULE
Maintenance Schedule Action needed
Daily Check water inlet screen and filter.
