CLEANING TECHNIQUES
• SAVE ALL INSTRUCTIONS
When cleaning with the pressure washer,
many cleaning tasks can be solved with water
alone, but for most tasks it is advantageous to
use a detergent also. A detergent ensures a
quick soaking of the dirt allowing the high
pressure water to penetrate and remove the
dirt more effectively.
Pressure washer chemicals are specially formulated to be used with your pressure washer.
APPLICATION OF SOAP OR
DEGREASER
1. Apply the solution to a DRY work surface.
On a vertical surface, apply horizontally
from side to side starting from the bottom
to avoid streaking.
NOTE: Wetting the surface first is not
recommended, as it dilutes the
detergent and reduces its cleaning
ability. Avoid working on hot surfaces
or in direct sunlight to minimize the
chances of the chemical damaging
painted surfaces. Damage may occur
to painted surface if chemical is
allowed to dry on the surface. Hold
nozzle far enough away from surface
to prevent damage to the surface.
2. Allow chemical to remain on the surface
for a short time before rinsing.
3. Rinse with clean water under high pressure.
On a vertical surface, first rinse from the
bottom up, then rinse from the top down.
Hold nozzle 6 to 8 inches from the work
surface at a 45° angle using the flat spray
as a peeling tool rather than a scrub brush.
APPLICATION OF WAX
1. Immediately after cleaning, apply pressure
washer wax. Place injection tube in
container of wax.
2. Apply the wax sparingly in an even layer.
Apply to wet surfaces from the bottom up
for even distribution and to avoid streaking.
3. Remove the suction tube from the wax
bottle and rinse off the surplus wax.
NOTE: IF SURPLUS WAX IS NOT
REMOVED, A HAZY FINISH MAY RESULT.
4. Wipe dry to reduce water spotting.
END OF CLEANING OPERATION
• SAVE ALL INSTRUCTIONS
When you have completed use of the chemical
injection system, remove tube from container.
Continue to run in low pressure position and
inject clean water through the tube and
injection system by placing end of tube in a
container of clean water. Continue to run until it
is thoroughly cleaned.

MAINTENANCE
• SAVE ALL INSTRUCTIONS
CONNECTIONS
Connections on pressure washer hoses, gun
and spray wand should be cleaned regularly
and lubricated with silicon grease to prevent
leakage and damage to the o-rings.
NOZZLE
Clogging of the nozzle causes the pump
pressure to be too high and cleaning is
immediately required.
WARNING
only be used when the spray nozzle is
disconnected from the gun or personal
injury could result.
1. Remove the nozzle from the wand.
2. Clear the nozzle with the nozzle cleaner
pin provided with the pressure washer.
3. Flush the nozzle backwards with water.
4. Re-install the nozzle into the wand.
Restart the pressure washer and depress the
trigger on the spray gun. If the nozzle is still
plugged or partially plugged, repeat above
items 1-4.
A nozzle cleaner must
WATER SCREEN
The pressure washer is equipped with a water
inlet screen to protect the pump. If the screen
is not kept clean, it will restrict the flow of
water to the pressure washer and may cause
damage to the pump. Do not damage the
screen while removing or cleaning screen.
Any foreign particles entering the pump may
damage the pump. Do not operate pressure
washer without the screen in place.
Remove the screen and back flush to remove
impurities from screen. Replace immediately.
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.
NOTE: Refer to the engine manufacturer’s
manual for service and maintenance of
the engine.
If the previous procedure does not clear the
nozzle, replace with a new nozzle.

STORAGE
• SAVE ALL INSTRUCTIONS
PUMP STORAGE
If you must store your pressure washer in a
location where the temperature is below 32°F,
you can minimize the chance of damage to
your machine by utilizing the following
procedure:
1. Shut off water supply and relieve pressure
in the spray gun by depressing the trigger.
Disconnect the garden hose from the
pressure washer, but leave the high pressure hose connected.
2. Tip the unit on its side with the inlet
connection pointing up.
3. Insert a small funnel (to prevent spilling)
into the inlet and pour in approximately 1/4
cup of RV antifreeze.
4. Disconnect spark plug wire.
5. Without connecting garden hose pull the
recoil several times to circulate the anti
freeze in the pump system. Continue to
add antifreeze and pull the recoil until the
antifreeze is expelled when the trigger is
pulled.
6. Turn the unit upright.
NOTICE
any possible ice from the pressure washer hoses, spray gun and wand.
Prior to restarting, thaw out
ENGINE STORAGE
When the pressure washer is not being
operated or is being stored 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 the spark plug hole, pull the recoil
starter several times and replace the plug.
Then pull the starter 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
the inside of the cylinder from rusting.
4. Cover the pressure washer and store in a
clean, dry place that is well ventilated away
from open flame or sparks.
NOTE: We recommend always using a
fuel stabilizer. A fuel stabilizer will
minimize the formulation of fuel gum
deposits during storage. The fuel
stabilizer can be added to the gasoline in
the fuel tank, or into the gasoline in a
storage container.
Another method of reducing risks of freeze damage is to drain your pressure washer as follow:
1. Stop the pressure washer and detach supply
hose and high pressure hose. Squeeze
the trigger of the discharge gun to drain all
water from the wand and hose.
2. Restart the pressure washer and let it run
briefly (about 5 seconds) until water no longer
discharges from the high pressure outlet.
