conditions, such as high-temperatures or dusty conditions, more
fre quent maintenance checks will berequired.
Engine
Consult the Engine Owner’s Manual for the man u fac tur er's
recommendations for any and all maintenance. NOTE: The
engine drain plug is located at the rear of theunit.
Pump
The pump was filled with oil at the factory. The pump on
this unit is maintenance free and requires no oil to be added
or changed. If there is a problem with the pump contact us

TroubleshootingGuide.
Connections
Connections on pressure washer hoses, gun and spray wand
should be cleaned regularly and lubricated with light oil or
lithium grease to prevent leakage and damage to the o-rings.
Nozzle Cleaning (Fig. L)
If the nozzle becomes clogged with foreign materials, such as
dirt, excessive pressure may develop. If the nozzle becomes
partially clogged or restricted, the pump pressure will pulsate.
Clean the nozzle immediately using the nozzle kit supplied and
the following instructions:
1. Shut off the pressure washer and turn off the watersupply.
2. Pull trigger on gun handle to relieve any waterpressure.
3. Disconnect the spray wand from thegun.

STORAGE
Engine
Consult the Engine Owner’s Manual for manufacturer’s
recommendations forstorage.
To Prevent Fuel-Related Problems
1. Add Ethanol Shield
TM
fuel stabilizer following the
manufacturer’s instructions. When adding a gasoline
stabilizer, fill the fuel tank with fresh gasoline. If only partially
filled, air in the tank will promote fuel deterioration during
storage. If you keep a container of gasoline for refueling, be
sure that it contains only freshgasoline.
2. After adding a gasoline stabilizer, run the engine outdoors
for 10 minutes to be sure that treated gasoline has replaced
the untreated gasoline in thecarburetor.
3. Turn the fuel valve to the OFFposition.
4. Continue to run the engine until it stops from the lack of
fuel in the carburetor fuel bowl. Running time should be less
than 3minutes.
Pump
The manufacturer recommends using SIMPSON

/
POWERWASHER
®
Pump Guard or equivalent when storing the
unit for more than 30 days and/or when freezing temperatures
are expected. SIMPSON

/ POWERWASHER
®
Pump Guard is
environmentallyfriendly.
NOTE: Using pump guard helps provide proper lubrication to
the internal seals of the pump regardless of temperature or
environment.
NOTICE: Risk of property damage. Use only SIMPSON®
