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.
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. Check for damage
before use.
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. (15,9 mm) 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 nozzle
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.
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
nozzles for Model CP5101
are included with this
pressure washer. The
yellow nozzle is a 15°
high pressure nozzle and
the black nozzle is a 65°
detergent nozzle.
Pressure can also be
adjusted by moving closer
or further away from the
cleaning surface and by
adjusting the spray fan
angle as shown.

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.
