Pressure washers are useful cleaning tools designed to
clean almost any surface in two easy steps.
o The first step involves applying an appropriate deter-
gent/solvent solution to penetrate and loosen grime.
The detergent is applied at low pressure to avoid
splashing, overspraying and waste. Leave the solution
on surface for 3 to 5 minutes to allow solution to work,
o The second step involves cleaning the surface you
have prepared with the pressure washer and then
rinsing it clean.
To apply detergent follow these steps:
o Prepare your detergent solution as required by your
job.
o Place small filter of the clear, detergent siphoning tube
into the detergent container (Fig. 15),
o To stop flow of detergent, turn knob clockwise or re
move filter from detergent or set nozzle to high pres

OPERATION
FIG. 20
o Grasp the starter grip and pull slowly until you fee!
resistance. Then pull rapidly one time.
® When engine starts, move choke lever to "RUN" posi
tion. If engine fails to start, move choke lever to "RUN"
position and puli starter rope (maximum 2 pulls).
® If engine fails to start, repeat the previous two steps.
o Once engine has started, place the Safety Latch on
spray gun to the OFF position.
o Press trigger on gun and wand assembly. Water should
spray out the nozzle.
o Adjust nozzle for correct pressure, spray angle. You
can also turn the pressure control knob to the desired
pressure setting.
o Your pressure washer is ready to use.
IMPORTANT: AN INTERNAL THERMAL RELIEF VALVE
HAS A MAXIMUM TEMPERATURE SETTING OF 140°F
(60°C). IF YOU RUN THE PUMP FOR 5 MINUTES WITH
OUT PRESSING THE TRIGGER ON THE SPRAY GUN,
1/2 TO 1 OUNCE OF WATER IS RELEASED THROUGH
THE VALVE TO COOL THE UNIT. THE SMALL AMOUNT
OF WATER WILL DRIP OUT THE BOTTOM OF PUMP.
LOW OIL PRESSURE SHUTDOWN SYSTEM
The engine is equipped with a low oil pressure sensor that
shuts down the engine automatically when the oil pressure
drops below 6 psi. If the engine shuts down by itself and
the fuel tank has enough gasoline, check engine oil level.
INITIAL STARTUP
A delay built in the shutdown system allows oil pressure to
build during starting. The delay allows the engine to run for
about 10 seconds before sensing oil pressure.
SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the
engine shuts down. As the system shuts down, Oie low oil
light comes ON. However, once the engine has stopped
rotating, this light will go OFF, See Fig. 22 for schematic.
RESTARTING
If you try to restart the engine within 5 seconds after it shuts
down, the engine may NOT start, The system needs 5 to
10 seconds to reset.
If you do restart the engine after such a shutdown and
have not corrected the low oil pressure, the engine
runs for about 10 seconds as described above and then
stops.
SIPHONING
We recommend that you DO NOT siphon your water supply
from sources other than from connecting to household
water supply.
TIPS
Initially clean an area and then check the surface for
damage. If no damage is found, you can assume it is
okay to continue cleaning. Detergents work best when
applied to dry surface.
For most effective cleaning, keep spray nozzle be
tween 8 to 24 inches of cleaning surface.
Allow the detergent to soak in between 3-5 minutes
before washing and rinsing.
For cleaning, start at lower portion of area to be washed

SERVICE AND ADJUSTMENTS
ENGINE SPEED
CAUTION: ENGINE SPEED WAS PROPERLY AD
A
JUSTED AT THE FACTORY AND SHOULD RE
QUIRE NO ADDITIONAL ADJUSTMENT. DO NOT
ATTEMPT TO CHANGE ENGINE SPEED. IF YOU
BELIEVE THE ENGINE IS RUNNING TOO FAST OR
TOO SLOW, TAKE YOUR PRESSURE WASHER TO
SEARS AUTHORIZED SERVICE CENTER FOR RE
PAIR AND ADJUSTMENT. CHANGING ENGINE
GOVERNED SPEED WILL VOID ENGINE WAR
RANTY.
Your pressure washer runs at a constant speed. This
constant operating speed is maintained by a mechanical,
flyweight type, fixed speed governor. DO NOT try to adjust
the governed speed setting for the following reasons:
o High engine speeds are dangerous and increase the
risk of personal Injury or damage to equipment.
Low engine speeds impose a heavy load on the engine
when sufficient engine power is not available and may
shorten engine life.
ADJUSTING VALVE CLEARANCE
After the first 50 hours of operation, you should adjust the
valve clearance in the engine.
When adjusting valve clearance, engine should be at room
temperature and piston should be at Top Dead Center
(TDC) of compression stroke (both valves closed). Correct
clearance is 0.05-0.1 mm. Adjust valve clearance as fol
lows:
o Loosen the rocker arm jam nut. Use an alien wrench
to turn the pivot ball stud while checking clearance
between the rockerarm and the vaive stem with a feeler
gauge (Fig. 27).
o When valve clearance is correct, hold pivot ball stud
with alien wrench and tighten rocker arm jam nut with
crows foot. Tighten jam nut to 65-85 inch-pounds
torque. After tightening jam nut, recheck valve clear
ance to make sure it did not change (Fig. 28).
NOZZLE MAINTENANCE
If the nozzle becomes restricted or clogged with foreign
materials, such as dirt, excessive pump pressure may
develop. A partially clogged nozzle can cause a pulsing
sensation during use. This generally is not a pump related
problem, but rather a clogged or partially restricted nozzle.
If the nozzle becomes clogged or partially restricted, imme
diately clean the nozzle with the kit included with your
pressure washer by following tiiese instructions:
o Shut off the engine and turn off the water supply.
0 Separate the wand from the gun.
o Remove nozzle from the end of the wand using a 2mm
or 5/64 alien wrench (like the one included in the kit).
o Use the wire included in the kit (Fig. 29) or a small paper
clip to free the foreign materials clogging or restricting
the nozzle.
17
Page 18
SERVICE AND ADJUSTMENTS
Remove additional debris by back flushing water sup
ply through wand (Fig. 30). Back flush between 30 to
60 seconds. Turn wand to stream spray and move
nozzle from low to high while flushing.
Reinstall nozzle into the wand. DO NOT overtighten.
Reconnect the wand to the gun
Reconnect the water supply, turn on the water, and
start the engine.
STORAGE
AFTER EACH USE
Water should not remain in the unit for long periods of time.
Sediments of minerals can deposit on pump parts and
“freeze” pump action. Follow these procedures after every
use:
o Flush detergent hose by placing the injector filter into
a pail of clear water while running Pressure Washer
with nozzle in low pressure mode. Flush until you can
see clear water running ttirough the tube.
o Shut off the engine and let it cool, then remove all
hoses.
CAUTION: BE SURE THE THROTTLE LEVER IS IN
A
“STOP” POSITION BEFORE YOU CONTINUE. IF
YOU START THE ENGINE WfTHOUTTHE PROPER
WATER SUPPLY CONNECTED, YOU CAN DAM
AGE THE PUMP.
® Empty the pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most of the
liquid in the pump.
o Coil the high pressure hose and inspect it for damage.
Cuts in ttie hose or fraying of it could result in leaks and
loss of pressure. Should any damage be found, replace
the hose. DO NOT attempt to repair a damaged hose
and use it. Replace the hose with the genuine Crafts
man part.
® Drain water from hose and properly hang it on the wire
support provided on the guide handle.
NOTE: To protect the unit from freezing temperatures, you
can draw windshield washer fluid into the pump by pouring
the washer fluid into a 3-foot section of garden hose con
nected to the inlet adaptor and pulling the recoil handle
twice,
® Store in a clean, dry area.
LONG TERM STORAGE
WARNING: NEVER STORE ENGINE WITH FUEL IN
A
TANK INDOORS OR IN ENCLOSED, POORLY VEN
TILATED AREAS WHERE FUMES MAY REACH AN
OPEN FLAME, SPARK OR PILOT LIGHT AS ON A
FURNACE, WATER HEATER, CLOTHES DRYER
OR OTHER GAS APPLIANCE.
If you do not plan to use the Pressure Washer for more than
30 days, you must prepare the engine for long term storage.
Test the pressure washer by operating with nozzle in
the high and in the low position.
NOTE: As always, prepare the pressure washer pump as
you would after each use.
It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose or tank during storage. Also, experience
indicates that alcohol-blended fuels (called “gasohol" or
using ethanol or methanol) can attract moisture which leads
to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in
storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow these
instructions:
Protect Fuel System; Engines stored over 30 days need
to be protected or drained of fuel to prevent gum deposits
from forming in fuel system or on essential carburetor parts.
® For engine protection use a fuel stabilizer. Mix stabilizer
with fuel in fuel tank and run engine for short time to
circulate stabilizer through carburetor.
• If you did use “gasohol", run engine until engine stops
from lack of fuel. Make sure you have water supply to
pump inlet connected and turned ON.
Change Oil: While engine is still warm, drain oil from
crankcase. Refill with recommended grade.
Oil Cylinder Bore: Remove spark plug and pour about 1/2
ounce (15ml) of engine oil into the cylinder. Cover spark
plug hole with rag. Crank slowly to distribute oil.
CAUTIONI AVOID SPRAY FROM SPARK PLUG
A
HOLE WHEN CRANKING ENGINE SLOWLY.
o Install spark plug. Do not connect spark plug wire.
OTHER
® Do not store gasoline from one season to another.
® Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
e If possible, store your unit indoors and cover it to give
protection from dust and dirt. BE SURE TO EMPTY
THE FUEL TANK.
a Cover your unit with a suitable protective cover that
does not retain moisture.
IMPORTANT: NEVER COVER YOUR PRESSURE
WASHER WHILE ENGINE AND EXHAUST AREAS ARE
WARM.
