HOW TO USE YOUR PRESSURE WASHER
IF YOU HAVE ANY PROBLEMS operatingyourpres-
surewasher, please call the pressurewasher helpline
at 1-800-222-3136.
A
WARNING NEVER adjustspray pattern
when spraying. NEVER put hands in front
of spray nozzle to adjust spray pattern.
You could be injured.
HOW TO USE THE-ADJUSTABLENOZZLE
On the end of your spray gun is a nozzle that you
can slideforward and backward and that you can
also twist from side to side. With theadjustable noz-
zle you can adjust the spray pattern to be either high
pressure or low pressure. You can also adjust the
spray so it is concentrated in a stream pattern or
expanded into a fan pattern.
• Slide the nozzle forward when you wish to adjust
the spray to low pressure mode. Slide the nozzle
backward to achieve high pressure.

Formost effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning sur-
face.
• If you get spray nozzle too close, especiallyusing
highpressure mode, you may damage the clean-
ingsurface.
APPLYING DETERGENT AND CLEANING WITH
ADJUSTABLE NOZZLE
IMPORTANT: Use soaps designed specifically for
pressure washers. Householddetergents coulddam-
age the pump.
IMPORTANT: You mustattach all hoses before you
startthe engine. Startingthe engine withoutall the
hoses connectedand withoutthe water turned ON
willdamage the pump.
To apply detergent follow these steps:
• Prepare the detergent solution as requiredby the
job.
Hang the detergent solutionon the "J" hook on
the wire form on the guide handle.
Place smallfilter on the clear, chemical injection
tube into the detergent container.
• Slide the adjustable nozzle forward to low pres-
sure mode. Detergent cannot be applied with
nozzle in high pressure position.
Note: The first step involvesapplying an appropriate
detergent/solvent solutionto penetrate and loosen
grime. The detergent is applied at low pressure to
avoid splashing,oversprayingand waste. Leave the
solutionon surface for 3 to 5 minutesto allowsolu-
tionto work.
Note: The second step involvescleaning the surface
you have preparedwith the pressurewasher and
then rinsingit clean.
Review the use of the adjustable nozzle.
Connect garden hose to waterinlet (see "TO
START PRESSURE WASHER"), checkthat high
pressure hose is connected to spray gun and
pump (see ASSEMBLY), and start engine.
For cleaning, start at lower portion of area to be
washed and work upward, usinglong, even over-
lapping strokes.
Allow the detergent to soak in between 3-5 min-
utes before washing and rinsing.
RINSING WITH THE PRESSURE WASHER
A
WARNING Be extremely careful if you must
use the pressure washer from ladder, scaf-
folding or any other relatively unstable loca-
tion. Pressure in a running washer builds in
the wand as you climb. When you press the
trigger, the recoil from the initial spray could
force you to fall, or ifyou are too close to the
cleaning surface, high pressure could force
you off a climbing apparatus.
D
Hook up the water supplyand startyour pressure
washer (see TO START THE PRESSURE WASHER).
Slide adjustable nozzle back to high pressure position
and wait for detergent to clear. Detergent will not flow
when in the high pressure mode.
When detergent has cleared you may wantto expand
the spray pattem for a more gentle rinsing action.
Start at top of area to be dnsed, working down with
same action as for cleaning.
You can also stop detergent from flowing by simply
removing siphon from bottle.
HOW TO STOP YOUR PRESSURE WASHER
• Move the Throttle ControlLever to the 'Slow' position,
Fast
Slow
Stop
• Wait for the engine to idle down.
• Move the Throttle Control Lever to the 'Stop' position.
• Simply shutting off the engine will not release
pressure in the system. Squeeze triggeron the
spray gunto relievepressure in the hose.
Note: A small amount of water will squirt out when
you release the pressure.
BEFORE STARTING THE PRESSURE WASHER
To operatethe engine youwillneedtodo the following:
ENGINE OIL
A 20 oz. bottle of SAE 30 weight oil is included in the
parts carton. Fill engine crankcase with recommended
oil until oil level is at FULL point on dipstick. Do not
overfill above that mark. POUR SLOWLY.
Note: When addingoilto the engine crankcase in the
future, use onlyhighquality detergent oil rated with API
service classificationSF or SG rated SAE 30 weight. Use
no specialadditives.
Select the oil's viscositygrade according to yourexpect-
ed operating temperature.
colder _ 32°F _ warmer
I
5W30 SAE 30
Although multi-viscosityoils (5W30, 10W30, etc.) improve
starting in cold weather, these multi-viscosity oils will
result in increasedoil consumption when used above
32°F. Check your engine oil level more frequently to
avoid possible damage from running low on oil.
• Place pressure washer on a level surface
• Clean area around oilfill and remove oil dipstick.
• Wipe dipstick clean.
• Pouroil from enclosed bottle into the oilfill opening
until oil reaches FULL mark on the dipstick. Stop and
check the oil level periodically. DO NOT OVERFILL.
• Installoildipstick, hand tightensecurely.
ADD GASOLINE
A
WARNING NEVER fill fuel tank indoors.
NEVER fill fuel tank when engine is running
or hot. DO NOT light a cigarette or smoke
when filling the fuel tank.
CAUTION: Do not overfill the fuel tank.
Always leave room for expansion.
Use regularUNLEADED gasolinewith the pressure
washer engine.Regular leaded gasoline may also be
used if UNLEADED is not available. Fuel tank capaci-
ty is 1.6 U.S. quart.
IMPORTANT: It isimportantto prevent gum deposits
from forming in essential fuel system parts such as the
carburetor,fuel filter,fuel hose ortank duringstorage.
Also, experience indicatesthat alcohol-blended fuels
(calledgasohol, ethanolor methanol) can attractmoisture
whichleads to separationand formation ofacids during
storage. Acidicgas can damage the fuel system of an
engine whilein storage.To avoid engine problems,the
fuel system shouldbe emptiedbefore storageof 30 days
or longer.See "Storage" on page 13. Never useengine
or carburetorcleaner productsin the fuel tank or perma-
nentdamage may occur.
• Clean area around fuel fill cap, remove cap.
• Add "UNLEADED" regulargasoline, slowly, to fuel
tank.
• Install fuel cap and wipe up any spilled gasoline.

Flush detergent hose by placing the injectorfilter into
a pail_f clear water while running Pressure Washer
with nozzle in low pressure mode. Flush until you can
see clear water runningthrough the tube.
Shut off the engine and let itcool, then remove all
hoses.
A
CAUTION: Be sure throttle lever is in
"STOP" position before you continue. If
you start engine without the proper water
supply connected, you can damage 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.
Coil the high pressurehose and inspectitfor damage.
Cuts inthe hose or fraying of itcould resultin leaks
and lossof pressure.Shouldany damage be found,
replace the hose. DO NOT attempt to repaira dam-
aged hose. Replace the hose with the genuine
Craftsman part.
It is importantto prevent gum depositsfrom forming in
essential fuel system parts such as the carburetor,fuel fil-
ter, fuel hose or tank duringstorage. Also, experience
indicatesthat alcohol-blendedfuels (calledgasohol,
ethanol or methanol) can attract moisturewhichleadsto .
separationand formation of acids duringstorage. Acidic
gas can damage the fuel system of an engine whilein
storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow these
instructions:
PROTECT FUEL SYSTEM
_k DANGER: Drain fuel into approved con-
tainer outdoors, away from open flame. Be
