Set up Precautions
1. Gasoline fuel and fumes are ammable, and
potentially explosive. Use proper fuel storage
and handling procedures. Do not store fuel
or other ammable materials nearby.
2. Have multiple ABC class re extinguishers nearby.
3. Operation of this equipment may create sparks
that can start res around dry vegetation. A spark
arrestor may be required. The operator should
contact local re agencies for laws or regulations
relating to re prevention requirements.
4. Set up and use only on a at, level,
well-ventilated surface.
5. The work area should have adequate
drainage to reduce the possibility of
a fall due to slippery surfaces.
6. Wear ANSI-approved safety goggles,
heavy-duty work gloves, and dust mask/
respirator during set up and use.
7. Use only oil and fuel recommended in the
“Specications” section of this manual.
8. Only use cold Water or pressure washer
detergent in this tool. Do not use caustic
materials, solvents, ammable materials, or
detergents not designed for pressure washers.
Use of any such material can cause injury,
or damage this tool or personal property.
9. Do not dry run this product. Dry running
will cause serious damage to the seals.
Make sure the water supply used for the
Pressure Washer is not dirty or sandy.
10. Prior to starting the Pressure Washer in
cold weather, check all of the parts of the
unit to make sure ice has not formed. Do
not store the unit anywhere that the
temperature will fall below 32° F (0° C).
Operating Precautions
Only use OUTSIDE and far away from windows,
doors, and vents.
2. Keep children away from the equipment,
especially while it is operating.
3. Do not leave the equipment unattended
when it is running. Turn off the equipment
(and remove safety keys, if available)
before leaving the work area.
4. Wear ANSI-approved safety goggles
and hearing protection during use.
5. People with pacemakers should consult their
physician(s) before use. Electromagnetic
elds in close proximity to a heart pacemaker
could cause pacemaker interference or
pacemaker failure. Caution is necessary when

6. Use only accessories that are recommended
by Harbor Freight Tools for your model.
Accessories that may be suitable for
one piece of equipment may become
hazardous when used on another one.
7. Do not operate in explosive atmospheres,
such as in the presence of ammable
liquids, gases, or dust. Gasoline-powered
engines may ignite the dust or fumes.
8. Stay alert, watch what you are doing and
use common sense when operating a
piece of equipment. Do not use a piece of
equipment while tired or under the inuence
of drugs, alcohol or medication.

Vibration Hazard:
This tool vibrates during use. Repeated or
long-term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should rst be examined by a
doctor and then have regular medical checkups to ensure medical problems are not being
caused or worsened from use. Pregnant women
or people who have impaired blood circulation
to the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue ngers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and ngers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration when there
is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
24. The high pressure water ow can damage
the work surface if not used properly. Always
test the spray in an open area rst.
25. When dispensing detergent, apply the detergent
to the cleaning area at low pressure only.
Detergent dispensing only works when the
spray wand is in the low-pressure position.

Service Precautions
1. Before service, maintenance, or cleaning:
a. Turn the engine switch to its “OFF” position.
b. Allow the engine to completely cool.
c. Then, remove the spark plug
wire(s) from the spark plug(s).
2. Keep all safety guards in place and in
proper working order. Safety guards include
mufer, air cleaner, mechanical guards,
and heat shields, among other guards.
Page 5
3. Do not alter or adjust any part of the
equipment or its engine that is sealed by the
manufacturer or distributor. Only a qualied
service technician may adjust parts that may
increase or decrease governed engine speed.
4. Wear ANSI-approved safety goggles,
heavy-duty work gloves, and dust mask/
respirator during use and service.
5. Keep the high pressure hose connected to
the pressure washer and spray gun while the
system is pressurized. Disconnecting the
pressure hose while the unit is pressurized
is dangerous, and may cause injury.
6. Do not allow the high pressure hose to come
in contact with any hot part of the unit. The
hose might be damaged, possibly causing
it to burst or leak under high pressure.
7. Maintain labels and nameplates on
the equipment. These carry important
information. If unreadable or missing, contact
Harbor Freight Tools for a replacement.
SAVE THESE INSTRUCTIONS.
8. If water is leaking out of the Pressure Washer
immediately turn off the unit. Unplug the
Pressure Washer, and discharge all pressure
before tightening ttings or having repair
work done by a qualied technician.
9. When the engine is running, do not allow
the Pressure Washer to remain idle for more
than two minutes. If allowed to remain idle,
the water in the unit will heat up, possibly
causing damage to the Pressure Washer.
10. Have the equipment serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the equipment
is maintained. Do not attempt any service or
maintenance procedures not explained in this
manual or any procedures that you are uncertain
about your ability to perform safely or correctly.
11. Store equipment out of the reach of children.
12. Follow scheduled engine and
equipment maintenance.
Refueling:
1. Do not smoke, or allow sparks, ames,
or other sources of ignition around the
equipment, especially when refuelling.
2. Do not rell the fuel tank while the
engine is running or hot.
3. Do not ll fuel tank to the top. Leave a little
room for the fuel to expand as needed.
4. Refuel in a well-ventilated area only.

Operating Instructions
Read the ENTIRE IMPORTANT
SAFETY INFORMATION section at the
beginning of this manual including
all text under subheadings therein
before set up or use of this product.
Starting the Engine
Inspect engine and equipment looking
for damaged, loose, and missing
parts before set up and starting. If
any problems are found, do not use
equipment until xed properly.
Checking Engine Oil Level
CAUTION Your Warranty is VOID if the engine’s
crankcase is not properly lled with oil before
each use. Before each use, check the oil level.
Do not run the engine with low or no engine
oil. Running the engine with no or low engine
oil WILL permanently damage the engine.
Checking Pump Oil Level
1. The Oil pump is lled with 3.75 -oz of
SAE 10W-30 NON DETERGENT oil at the
factory. Under normal conditions there is no
reason to add any oil or change the oil.
2. Turn off engine, allow it to cool and
disconnect the spark plug wire.
3. Twist the Dipstick on the Pump Breather Plug
until the arrow on it lines up with the arrow
on the Plug and remove the Dipstick.
4. Remove the Pump Breather Plug from the Pump.
Clear oil

Figure 3
Remove dipstick and wipe away the oil with dry
3.
cloth. Reinsert the dipstick into the oil ller neck,
but do not screw in, then remove it to check the oil
level. The oil level should be up to the full level as
shown above. Low oil level can trigger the low oil
sensor to shutdown the engine and prevent restart.
4. If the oil level is low, add the appropriate type of
oil until the oil level is at the bottom lip of the oil ll
hole.
Oil type:
32° F or above = SAE 10W-30
Below 32° F = SAE 5W-30.
5. Replace the Oil Filler Cap.
CAUTION Do not run the engine with too little or too
much oil. The engine will be
permanently damaged.

Wipe the Dipstick off with a clean, dry cloth.
Insert the Dipstick into the pump housing and
remove it. The oil level should be at least to
the lower (L) notch on the dipstick, but not
above the upper (H) notch. Add SAE 10W30 NON-DETERGENT oil as needed.
7. Thread the Pump Breather Plug
back into the pump.
