IMPORTANT SAFETY WARNINGS
ELECTRICALPRECAUTIONS:
1. GROUNDINGINSTRUCTIONS:
This product must be grounded. If it should malfunction or breakdown,
grounding provides a path of least resistance for electric current to reduce the
risk of electric shock. This product is equipped with a cord having an
equipment-grounding conductor and a grounding plug. The plug must be
plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
2. DANGER:
Improper connection of the equipment-grounding conductor can result in a
risk of electrocution. Check with a qualified electrician or service personnel
if you are in doubt as to whether the outlet is properly grounded. Do not modify
the plug provided with the product - if it will not fit the outlet, have a proper outlet
installed by a qualified electrician. Do not use any type of adaptor with this
product.
3. GROUNDFAULTINTERRUPTERPROTECTION:
This pressure washer is provided with a Ground Fault Circuit Interrupter
(GFCI) built into the plug or the power supply cord. This device provides
additional protection from the risk of electric shock. Should replacement of the
cord become necessary, use only identical replacement parts that include
GFCIprotection.
4. EXTENSIONCORDS:

time.
1. Selection of high pressure can be achieved by turning the protective collar
clockwise as shown in Figure 1, left. While in the high pressure mode, water
is directed solely through the 15°spray nozzle creating a concentrated high
pressure "fan" spray.
2. Selectionof lowpressuredetergent applicationcanbe achieved byturningthe
collar counterclockwise as shown in Figure 2, left. Once the pressure is low
enough,the detergent injectoron the pressurewasher will drawdetergent into
thesystem. Asthecollaristurned, a water/detergentmixture exitsnotonlyfrom
the spray nozzle, but also around the nozzle. This creates a "fan/cone"
combination spray pattern.

WATERSUPPLY:
1. Select a water supply hose which is a quality grade of garden hose
measuring at least 3/4" ID and no longer than 50 feet.
2 Check the water inlet strainer (14) to ensure it is clean and free of any
obstructions. Periodiccleaningof thewaterstrainer willhelpprevent pump
problems. As a strainer becomes obstructed, it restricts proper flow of
watertothepump. This canresultincavitations which willcausepremature
failure of pump packings and valves. Using a screw driver, remove the
screen, clean or replace with Nilfisk-Advance #56632999 if necessary.
3. Connect the hoses:
a. Connect one end of the water supply hose to the water inlet (15) of the
unit.
b. Connect the other end of the hose to your pressurized water supply.
c. Connect thehighpressure dischargehose (23)tothe wateroutlet (20)
of the unit.
4. Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 20 pounds per square
inch (PSI) and a maximum of 125 PSI. (A typical outdoor faucet
will generally supply this PSI if turned completely "ON")
b. Incoming GPM must be approximately one gallon more than the
outgoing GPM stated on the pressure washer nameplate. (You
can check GPM by timing how long it takes to fill a 5 gallon
container)
c. Incoming watertemperaturemust notexceed190°F/ 88°C. Excessive
pump damage may result if the water temperature exceeds this
acceptablelevel.
5. Neverallowtheunit tooperatewithouttheincoming waterlineattachedand

6. With the trigger gun locked in the "OFF" position, turn the collar at the end
of the wand counterclockwise for low pressure as shown in figure 2, right.
7. To apply solution, unlock the trigger gun and squeeze the trigger. In a few
momentsa detergent/watermixture will exitthe lowpressure nozzle.Start
sprayingthelower portionofthe surface beingcleanedand moveup,using
long overlapping strokes. Applying from the bottom up helps avoid
streaking. Allowto soakbriefly. (Avoid workingon hotsurfaces orin direct
sunlightto minimizethe chancesof thedetergent drying,which may result
in damaging surfaces) Be certain to rinse a small section at a time.
8. To rinse: lock the trigger gun in the "OFF" position, turn the collar at the
end of the wand clockwise. Unlock the trigger gun and spray. It will take
about 30 seconds to purge all detergent from the line. For best rinsing
results, start at the top and work down.
9. Siphon a gallon of water through the low pressure detergent injection
system after each use. This prevents the possibility of corrosion or
detergent residue causing mechanical problems during the next use.
SHUT-DOWN:
1. Move the On/Off switch to the "OFF" position to turn unit off.
2. Turn the water supply "OFF".
3. Pointing the gun in a safe direction, trigger gun momentarily to relieve
any trapped pressure.
4. Once pressure is relieved, disconnect the nozzle assembly.
5. Disconnect the unit from the power source.
6. Disconnect and drain gun, wand and hoses.
7. Wipeunit cleanand storewithgun, wandandhoses ina safe, non-freezing
area.

PUMPMAINTENANCE:
Thepump oilmust bechanged after thefirst 25hours ofoperation. Once theinitial
oil change has been completed, it is recommended the oil be changed every 3
monthsor250 hourintervals. Ifoil appearsdirtyor milky,changesmay berequired
at a greater frequency. Use SAE 30W Non-Detergent oil and fill only to the center
of the oil sight glass. DO NOT OVERFILL!
NOZZLEMAINTENANCE:
Waterflowthrough thespraynozzle will erodetheorifice, makingitlarger, resulting
in a pressure loss. Nozzles should be replaced whenever pressure is less than
85% of the maximulm. The frequency of replacement will depend upon such
variables as mineral content in the water and number of hours the nozzle is used.

STORAGE & MAINTENANCE
WINTERIZING:
1. Forstorageandtransportationpurposesinsubfreezingambienttemperatures,
it will be necessary to winterize this unit. This unit must be protected to the
lowest incurred temperature for the following reasons:
a. If any part of the pumping system becomes frozen: excessive
pressure may build up in the unit which could cause the unit to burst
resulting in possible serious injury to the operator or bystanders.
b. The pumping system in this unit may be permanently damaged if
frozen. FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
If you must store your unit in an area where the temperature may fall below
32°F, you can protect your unit by following the procedure outlined below.
1. Gather the following items:
a. Two 5 gallon containers.
b. Onegallonofantifreeze.(Nilfisk-Advancerecommendsand
environmentallysafeantifreeze)
c. Water supply.
d. Three foot hose, 1/2-3/4 I.D. with a 3/4 inch male garden
hose fitting.
2. Procedure:
a. Shut off the unit and water supply.
b. Relieve system pressure by pointing the trigger gun in a safe
direction and squeezing the trigger until water flow ceases
to exit the nozzle.
c. Lock the trigger gun in an OFF position and remove the
nozzle.
d. In a 5 gallon container, mix the antifreeze and water according
tomanufacturer's recommendationsfor the temperature
you are winterizing to.
NOTE: Properwinterizingisbasedontherecommendedmanufacture'sinstructions
listedonthe "ProtectionChart"shown ontheback labelofmost antifreeze
containers.
e. Remove the water supply hose from the unit and attach the
3 foot hose securely to the inlet connection. Submerge the
opposite end into the antifreeze solution.
f. Point the wand into the empty container and start the unit.
g. Trigger the gun until the antifreeze begins to exit the wand.
Release the trigger for 3 seconds, then trigger the gun for 3
seconds. Continue cycling the gun several times until all the
antifreeze mixture is siphoned from the container.
h. Detach the 3 foot hose from the unit and drain any excess
antifreeze back into the 5 gallon container.
i. Disconnect the hose/gun/wand assembly from the unit and
drain any excess antifreeze back into the 5 gallon container.
j. Store the hose, gun and wand with the unit in a safe area.
k. Store antifreeze solution for next use or dispose of according
to state EPA laws.
3. OptionalProcedure:
a. Shut the unit off.
b. Relieve system pressure by pointing the trigger gun in a safe
direction and squeezing the trigger until water flow ceases
to exit the nozzle.
c. Disconnect and drain the hose, gun and wand.
d. Start the unit and allow it to run until all the water exits the
unit. Once the water has stopped flowing from the unit, turn
the unit off.
NOTE: When using this procedure, caution should be used as ice
chips can form from drops of water which could cause the
unit to burst if starting before completely thawed.
STARTINGUNITAFTEREXTENDEDSTORAGE:
1. BE CERTAIN the unit is NOT plugged into the power source.
2. Priorto restartingthe unit, thawout anypossible icefromthe wand,gun, hose
and unit.
3. After following all "PREPARATION" instructions, start the unit momentarily
andimmediatelyturn"OFF" toensureallpartsare lubricatedbeforeoperation.
