be required. The operator should contact: Local
fi re agencies for laws or regulations relating to fi re
prevention requirements.
7. Allow engine to cool for 1-2 minutes before refueling. If any fuel is spilled, make sure the area is
dry before testing the spark plug or starting the
engine. (Fire and/or explosion may occur if this is
not done.)
IMPORTANT SAFETY INFORMATION
PRESSURE WASHER
Gasoline engines on mobile or portable equipment
shall be refueled:
a. outdoors;
b. with the engine on the equipment stopped;
c. with no source of ignition within 10 feet of
the dispensing point; and
d. with an allowance made for expansion of the
fuel should the equipment be exposed to a
higher ambient temperature.
In an overfi lling situation, additional precautions are
necessary to ensure that the situation is handled
in a safe manner.
WARNING: Risk of injury. Disconnect battery
ground terminal before servicing.
8. When in use , do not place machine near fl ammable
objects as the engine is hot.
9. Oil burning appliances shall be installed only in
locations where combustible dusts and fl ammable
gases or vapors are not present. Do not store or
use gasoline near this machine.
10. Use No. 1 or No. 2 heating oil (ASTM D306) only.
NEVER use gasoline in your fuel oil tank. Gasoline
is more combustible than fuel oil and could result
in a serious explosion. NEVER use crankcase or
waste oil in your burner. Fuel unit malfunction could
result from contamination.
11. Do not confuse gasoline and fuel oil tanks. Keep
proper fuel in proper tank.

STEP 1: Check engine oil level. Oil level should be level with the bottom
of the oil fi ller neck. Be sure the machine is level when checking the oil
level. (Refer to the engine's operating manual included with machine.)
We recommend that the oil be changed after the fi rst 5 hours of use, then
once every 50 hours. Note: Improper oil levels will cause low oil sensor
to shut off engine. IMPORTANT! Do not run engine with high or low
oil levels as this will cause engine damage.

observe oil level in oil window (if
equipped). Use 40 wt. non detergent oil. The Legacy Axial Pump
does not require maintenance. Attemping to check oil on this pump
may damage it and will void your

The fi ve color-coded quick connect nozzles provide a wide array of
spray widths from 0° to 40° and are easily accessible when placed in the
convenient rubber nozzle holder, which is provided on the front of the
machine.
NOTE: For a more gentle rinse, select the white 40° or green 25° nozzle.
To scour the surface, select the yellow 15° or red 0° nozzle. To apply detergent select the black nozzle.
STEP 9: Pull the starter grip. If the engine fails to start
after 2 pulls, squeeze the trigger gun to release pressure and repeat step. Return starter gently. After the
engine warms up enough to run smoothly, move choke
to run position and throttle to fast position.

DETERGENT AND GENERAL CLEANING TECHNIQUES
PRESSURE WASHER
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nausea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Connect detergent injector to discharge nipple
on machine. Connect high pressure hose to injector
with quick coupler. (Check to make sure locking coupler
sleeves are in proper position before applying water
pressure).

THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 1-2
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high temperatures. When the water reaches this temperature, the
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal
device prevents internal damage to the pump.
OPERATOR’S MANUAL
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to
be drying, simply wet down surface with fresh water.
If needed, use brush to remove stubborn dirt. Rinse
at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately
1 foot from cleaning surface. Use overlapping strokes
as you clean and rinse any surface. For best surface
cleaning action spray at a slight angle.
STEP 2: Use detergent designed
specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent
solution as required by manufacturer. Fill a container with pressure
washer detergent. Place fi lter end of
detergent suction tube into detergent
container.
STEP 3: With safety latch on spray
gun engaged, secure black detergent
nozzle into quick coupler. NOTE:
Detergent cannot be applied using
red, yellow, green or white nozzles.
STEP 4: With the engine running,
pull trigger to operate machine. Liquid detergent is
drawn into the machine and mixed with water. Apply
detergent to work area. Do not allow detergent to dry
on surface.
IMPORTANT: You must fl ush the detergent injection system after each use by placing the suction
tubeinto a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.
8.780-013.0 • Xpert-HD • Rev. 10/12
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
extreme caution as pressure washer may remove
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desired high pressure nozzle. NOTE: You can also stop
detergent from fl owing by simply removing detergent
siphon tube from bottle.

SHUTTING DOWN AND CLEAN-UP

CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun trigger to release pressure.
2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately.
4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room which
does not reach freezing temperatures.
CAUTION: Failure to follow the above directions will
result in damage to your pressure washer.
When the pressure washer is not being operated or is
being stored for more than one month, follow these
instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve
and carburetor.
3. Pour about one teaspoon of engine oil through
12
the spark plug hole, pull the starter grip several

STORAGE
times and replace the plug. Then pull the starter
grip slowly until you feel increased pressure which
indicates the piston is on its compression stroke and
leave it in that position. This closes both the intake
and exhaust valves to prevent rusting of cylinder.
4. Cover pressure washer and store in a clean, dry
place that is well ventilated away from open fl ame
or sparks. NOTE: The use of a fuel additive, such as
STA-BIL
tion of fuel deposits during shortage. Such additives
may be added to the gasoline in the fuel tank of the
engine, or to gasoline in a storage container.
After Extended Storage
Engine Maintenance
During the winter months, rare atmospheric conditions
may develop which will cause an icing condition in the
carburetor. If this develops, the engine may run rough,
lose power and may stall. This temporary condition can
be overcome by defl ecting some of the hot air from the
engine over the carburetor area. NOTE: Refer to the
engine manufacturer's manual for service and maintenance of the engine.
