Do not use acids, alkalines, solvents, flammable  
material, bleaches, or industrial grade solutions  
in this product. These products can cause physical  
injuries to the operator and irreversible damage to the  
machine.  
Loosen fuel cap slowly to release pressure and to keep  
fuel from escaping around the cap.  
Replace all fuel tank and container caps securely.  
Wipe spilled fuel from the unit. Move 30 feet away from  
refueling site before starting engine.  
Always operate the machine on a level surface. If the  
engine is on an incline, it could seize due to improper  
lubrication (even at the maximum oil level).  
If fuel is spilled, do not attempt to start the engine but  
move the machine away from the area of spillage and  
avoid creating any source of ignition until fuel vapors  
have dissipated.  
WARNING: High pressure jets can be dangerous if  
subject to misuse. The jet must not be directed at  
persons, animals, electrical devices, or the machine  
itself.

use of this product, familiarize yourself with all operating  
features and safety rules.  
RECOIL STARTER  
The recoil starter is pulled to start the machine.  
SPRAY WAND  
The spray wand has a gripping surface that provides added  
control of the spray wand and helps reduce fatigue. Both  
the spray wand and extension have storage areas located  
on top of the machine.  
BRIGGS & STRATTON ENGINE  
This Briggs & Stratton Q45engine enables the pressure  
washer to achieve 2,200 PSI (pounds per square inch) at a  
rate of 2.0 GPM (gallons per minute).  
THERMAL RELIEF VALVE  
FUEL TANK  
This fuel tank has a maximum capacity of 1 quart  
(.95 liters). Use unleaded automotive gasoline in the  
engine.  
This pump feature will prevent water temperatures from  
reaching harmful levels by releasing a small amount of water  
from a rubber hose. Once the water has drained, the thermal  
relief valve will reset itself.  
HOSE STORAGE  
Once the high pressure hose is rolled, hang it on the front of  
the machine using the hook and loop strap for convenient  
storage.  
TRIGGER WITH LOCK OUT  
Pulling the trigger releases a stream of water for high  
pressure cleaning. The lock out provides protection against  
unauthorized use.

MAINTENANCE  
CLEANING THE AIR FILTER  
See Figure 18.  
WARNING:  
A dirty air filter will cause starting difficulty, loss of  
performance, and shorten the life span of the engine. Check  
the air filter monthly. For best performance, replace the air  
filter at least once a year.  
When servicing, use only identical replacement parts.  
Use of any other parts may create a hazard or cause  
product damage.  
NOTE: DO NOT remove the shroud as you could disconnect  
or loosen the wire connecting the OFF switch to the engine  
making it inoperable.  
WARNING:  
Always wear safety goggles or safety glasses with side  
shields during power tool operation or when blowing  
dust. If operation is dusty, also wear a dust mask.  
Using the hole in the shroud for easy access, remove the  
air filter screw.  
Remove the air filter cover.  
Lift the edge of the air filter carefully and pull it out.  
Wash the air filter with warm, soapy water.  
Rinse and squeeze to dry.  
WARNING:  
Before inspecting, cleaning or servicing the machine, shut  
off engine, wait for all moving parts to stop, and discon-  
nect spark plug wire and move it away from spark plug.  
Failure to follow these instructions can result in serious  
personal injury or property damage.  
Put small amount of motor oil (SAE 30) on the filter  
sponge. Squeeze out the excess oil then reinstall the air  
filter.  
NOTE: Make sure the filter is seated properly inside the  
cover. Installing the filter incorrectly will allow dirt to enter  
the engine, causing rapid engine wear.  
NOTE:TheBriggsandStrattonQ45enginehasaseparate  
warranty found in the engine manual (included with this  
product).  
Reinstall the air filter cover and tighten securely using the  
air filter screw.  
GENERAL MAINTENANCE  
Avoid using solvents when cleaning plastic parts. Most  
plastics are susceptible to damage from various types of  
commercial solvents and may be damaged by their use. Use  
clean cloths to remove dirt, dust, oil, grease, etc.

Before running the engine, perform the following pre-  
operation steps:  
Check that all bolts, nuts, etc., are securely tightened.  
Make sure the air filter is clean.

MAINTENANCE  
CHANGING THE OIL  
See Figure 19.  
NOTE: Run the engine out of gas to prevent gas spills if  
machine is tilted. Allow 30 minutes of “cool down” time.  
OIL DRAIN PLUG  
CONTAINER  
Place a container under the pressure washer.  
Remove the oil drain plug and drain the old oil.  
NOTE: Drain the oil while the engine is still warm but not  
hot. Warm oil will drain quickly and more completely.  
Replace the oil drain plug.  
Replace the oil with new, clean oil. This engine will hold  
20 oz. or .6 liters of oil (SAE 30).  
NOTE: Consult hazardous waste management guidelines in  
your area for the proper way to dispose of used oil.  
CHECKING A FOULED SPARK PLUG  
See Figure 20.  
Clean carbon deposits off the spark plug electrode using  
Fig. 19  
a plug cleaner or wire brush.  
Check electrode gap. The gap should be .6 mm - .7 mm.  
Adjust the gap, if necessary, by carefully bending the side  
electrode.  
(Recommended spark plug: NGK BR-6HS; CHAMPION  
RL86C.)  
NOZZLE MAINTENANCE  
See Figure 21.  
0.6 - 0.7mm  
Excessive pump pressure (a pulsing sensation felt while  
squeezing the trigger) may be the result of a clogged or  
dirty nozzle.  
Fig. 20  
NOZZLE  
CLEANING TOOL  
Turn off the pressure washer and shut off the water  
supply. Pull trigger to release water pressure.  
NOZZLE  
Remove the nozzle from the spray wand.  
NOTE: Never point the spray wand at your face.  
Using the nozzle cleaning tool provided, free any foreign  
materials clogging or restricting the nozzle.  
Using a garden hose, flush debris out of nozzle by back  
flushing (running the water through the nozzle backwards  
or from the outside to the inside).  
Fig. 21  
Reconnect the nozzle to the spray wand.  
Turn on the water supply and start the engine.
