STEP 1:
Check engine oil level. Oil level should be level with the bottom
of the oil  ller neck. Be sure the ma chine is level when checking the oil
level. (Refer to the en gine's op er at ing manual included with machine.) We
rec om mend that the oil be changed after the  rst 5 hours of use, then once
every 50 hours.
Note:
Im prop er 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.
STEP 3:
Connect garden hose
to the cold water source and turn
wa ter on completely. Never use
hot wa ter.
STEP 5:
Rotate the fuel shut-off valve to the "On" po-
si tion. Slide the fuel valve lever to the "ON" position.
When the engine is not in use, leave the fuel valve in
the "OFF" position.
STEP 4:
Trigger the spray gun to
elim i nate trapped air then wait for a
steady  ow of water to emerge from
the spray noz zle.

sleeves are in proper position before ap ply ing wa ter
pres sure).
STEP 2:
Use detergent de signed
spe ci cal ly for pres sure washers.
House hold de ter gents could dam-
age the pump. Pre pare detergent
so lu tion as required by the man u -
fac tur er. Fill a container with pres-
sure washer de ter gent. Place the
 lter end of detergent suction hose
into the de ter gent container.
STEP 3:
With safety latch on spray

NOTE:
De ter gent can not be ap plied using red, yellow,
green or white noz zles.
STEP 4:
With the engine run-

into the ma chine and mixed with
water. Apply de ter gent to work
area. Do not al low de ter gent to

IMPORTANT: You must  ush the detergent in jec tion
sys tem after each use by plac ing the suction hose
into a buck et of clean wa ter, then run the pres sure
wash er in low pres sure for 1-2 minutes.
WARNING

AND GENERAL CLEANING
TECHNIQUES
THERMAL PUMP
PROTECTION
If you run the engine on your pres sure wash er for 3-5
min utes with out pressing the trig ger on the spray gun,
cir cu lat ing water in the pump can reach high tem per a-
tures. When the water reach es this tem per a ture, the
pump pro tec tor engages and cools the pump by dis-
charg ing the warm water onto the ground. This ther mal
de vice pre vents internal dam age to the pump.
CLEANING TIPS
Pre-rinse clean ing surface with fresh water. Place de-
ter gent suc tion tube di rect ly into clean ing solution and
ap ply to sur face at low pressure (for best re sults, lim it
your work area to sec tions ap prox i mate ly 6 feet square
and al ways ap ply de ter gent from bottom to top). Allow
de ter gent to re main on sur face 1-3 min utes. Do not al-
low de ter gent to dry on sur face. If sur face appears to
be drying, sim ply wet down sur face with fresh water. If
need ed, use brush to re move stub born dirt. Rinse at
high pres sure from top to bottom in an even sweep ing
mo tion keep ing the spray nozzle ap prox i mate ly 1 foot
from clean ing sur face. Use over lap ping strokes as you
clean and rinse any sur face. For best surface clean ing
action spray at a slight an gle.
Recommendations:
•
Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
dis tance for maximum cleaning results.
•
If painted surfaces are peeling or chipping, use
ex treme caution as pressure washer may re move
the loose paint from the surface.
•
Keep the spray nozzle a safe distance from the
sur face you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no dam age is found, continue to pressure wash-
ing.
CAUTION - Never use:
CAUTION - Never use:
CAUTION - Never use:
CAUTION - Never use:
•
Bleach, chlorine products and other corrosive
chem i cals
•
Liquids containing solvents (i.e., paint thinners,
gas o line, oils)
•
Tri-sodium phosphate products
•
Ammonia products
•
Acid-based products
These chemicals will harm the machine and will dam-
age the surface
being cleaned.
RINSING
It will take a few sec onds for the de ter gent to clear.
Apply safe ty latch to spray gun. Re move black soap
noz zle from the quick cou pler. Select and in stall the

SHUTTING
DOWN
AND CLEAN-UP
STEP 1:
Remove detergent suc tion
tube from container and insert into
one gallon of fresh water. Slide noz zle
for ward for low pressure or to con nect
black detergent nozzle. Pull trig ger on
spray gun and si phon water for one
minute.
STEP 2:
Turn engine switch to "OFF"
position.
STEP 3:
Turn off water
sup ply.
STEP 5:
Disconnect the garden
hose from the water inlet on the
machine.
STEP 6:
Disconnect the high
pres sure hose from high pres-
sure out let.
STEP 7:
En gage
the spray gun safe ty
lock.
STEP 4:
Press
trig ger to re lease
wa ter pres sure.
CAUTION: Al ways store your pressure washer in a
lo ca tion where the temperature will not fall be low
32°F (0°C). The pump in this machine is sus cep ti ble
to permanent dam age if fro zen. FREEZE DAM AGE
IS NOT COV ERED BY WARRANTY.
1.
Stop the pressure washer, squeeze spray gun trig-
ger to release pressure.
2.
Detach water supply hose and high pressure hose.
3.
Turn on the machine for a few seconds, until re-
main ing water exits. Turn engine off im me di ate ly.
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: Fail ure to follow the above di rec tions will
result in dam age to your pres sure washer.
When the pres sure washer is not being operated or is
be ing stored for more than one month, follow these
in struc tions:
1.
Replenish engine oil to up per level.
2.
Drain gas o line from fuel tank, fuel line, fuel valve
and carburetor.
3.
Pour about one teaspoon of engine oil through
the spark plug hole, pull the starter grip several
times and re place the plug. Then pull the starter
grip slow ly until you feel increased pressure which
indicates the pis ton is on its compression stroke and
leave it in that position. This closes both the intake
and ex haust valves to prevent rusting of cylinder.
4.
Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open  ame
or sparks.
NOTE:
The use of a fuel additive, such
as STA-BIL
®
, or an equivalent, will minimize the
for mu la tion of fuel deposits during shortage. Such
ad di tives may be added to the gasoline in the fuel
tank of the engine, or to the gasoline in a storage
con tain er.
After Extended Storage
CAUTION: Prior to restarting, thaw out any
pos si ble ice from pressure washer hos es,
spray gun or wand.
Engine Maintenance
During the winter months, rare atmospheric conditions
may develop which will cause an icing con di tion in the
car bu re tor. If this de vel ops, the engine may run rough,
lose power and may stall. This temporary condition can
be overcome by de ecting some of the hot air from the
en gine over the carburetor area.
NOTE:
Refer to the

nance of the engine.
