Assembling Your Pressure Washer

Your Craftsmanpressure washer will needassembly before

operation:

1. Fill out and sendin registration card.

2. Attach handle.

3. Add oil to engine crankcase.

4. Add fuel to fuel tank.

5. Verify pump oil dipstick (A) has beeninstalled into pump.

6. Connectpressure hose to spray gun and pump.

7. Connectwater supply to pump.

8. Attach nozzleextensionto spray gun.

9. Select/attach quick connect spray tip to nozzle

extension.

Attach Handle

1. Placehandle (B) onto handlesupports (C) connectedto

main unit. Makesure holes (D) in handle align with

holes (D) on handlesupports.

NOTICE It may be necessaryto move the handle supports

from side to side in order to align the handle so it will slide

over the handle supports.

2. Insert carriagebolts (E)through holesfrom outside of

unit and attach aplastic knob (F) from insideof unit.

Tighten by hand.

3. Insert multi-colored spray tips in spaces provided in

handle.

Add Engine Oil 1.

1. Placepressurewasher on a flat, levelsurface.

2. Cleanareaaround oil fill and remove oil fill cap/dipstick.

3. Using oil funnel (optional), slowly pour contents of both

provided oil bottles into oil fill opening to the point of

overflowing. 3.

NOTICE Improper treatment of pressure washer could

damage it and shorten its life.

• DONOTattemptto crank or startthe engine before it has been

properly servicedwith the recommended oil. This could result in

an engine failure.

4. Replaceoil fill cap/dipstick and fully tighten.

Add Fuel

,& WARNING Fueland its vapors areextremelyflammable

and explosivewhich could causeburns,

fire or explosionresulting in death,

serious injury and/orproperty damage.

WHENADDINGFUEL

• Turn pressure washerengine OFFandlet it cool at least2

minutes beforeremoving fuel cap. Loosencap slowly to relieve

pressure in tank.

• Fillfuel tank outdoors.

• DONOToverfill tank. Allow spacefor fuel expansion.

• If fuel spills, wait until it evaporatesbefore starting engine.

• Keepfuel awayfrom sparks, open flames, pilot lights, heat,and

other ignition sources.

• Checkfuel lines,tank, cap andfittings frequently for cracks or

leaks. Replaceif necessary.

• DONOTlight a cigarette or smoke.

Use clean,fresh, regular UNLEADEDfuel with a

minimum of 86 octanewith equipment. DONOTmix oil

with fuel.

Placepressure washer on a levelsurface. Cleanarea

around fuel fill cap, remove cap.

Slowly add regular unleadedfuel to fuel tank. Becareful

not to overfill. Allow about 1" of tank space for fuel

expansion,as shown here.

MaximumFuelLevel

4. Install fuel capand wait for any spilled fuel to evaporate.

CAUTION! Alcohol-blendedfuels (calledgasohol, ethanol or

methanol) can attract moisture, which leadsto separation and

formation of acids during storage.Acidic gascan damagethe

fuel system of an enginewhile in storage.

To avoidengine problems, the fuel system should betreated

with a fuel preserver or emptied before storageof 30 days or

longer. If adding a fuel preserver,fill thefuel tank with fresh

fuel. If only partially filled, air in the tank will promote fuel

deterioration during storage. If fuel preserver is not used,

drain the fuel tank, start the engine and let it run until the fuel

lines and carburetor are empty. Usefresh fuel next season.

SeeStoragefor additional information.

NEVERuseengine or carburetor cleanerproducts in the fuel

tank as permanent damagemay occur.

Lubricate O-Rings

Lubrication of o-rings is extremely important for installation

and operation. The useof a lubricant (petroleum or synthetic

grease)during assembly helpsseat o-rings properly and

provides an improved seal. It also helps protect the o-ring

from damageby abrasion, pinching or cutting and extends

the life of the o-ring.

NOTICE ALWAYSapplya small amount of lubricant on

o-rings prior to assemblingthe garden hoseto the pump

inlet (A), high pressure hoseto pump outlet (B), high

pressure hose(C), spray gun (D), and nozzleextension(E).

Lubricateall connectionsshownbelow, followingthese

instructions:

1. Inspect and clean connecting surfaces prior to

lubrication and assembly.

2. Uselubricants sparingly during assembly;a light film is

all that is required.

3. Usea small brush or cotton swab to applygrease

directly to o-rings wherethey are not accessible (QC

fitting, IVI22fitting).

ConnectHoseandWater Supplyto Pump

NOTICE DONOTrun the pump without the water supply

connectedand turned on.

• Damagetoequipmentresultingfrom failuretofollowthis

instructionwillvoidwarranty.

4. Run water through garden hose for 30 seconds to clean

out any debris. Turn off water.

NOTICE DONOTsiphon standing water for the water

place.

UsageTips

• For most effective cleaning, keepspray tip from 8 to

24 inches (20 to 61 cm) awayfrom cleaning surface.

CleanDebris

Daily or beforeuse, cleanaccumulated debris from pressure

washer. Keeplinkage, spring and controls clean. Keeparea

around and behind muffler free from anycombustible debris.

Inspect cooling air slots and openings on the pressure

washer.These openings must be kept cleanand

unobstructed.

Pressurewasher parts should be kept clean to reducethe

risk of overheating and ignition of accumulated debris.

• Usea damp cloth to wipe exterior surfaces clean.

NOTICE Improper treatment of pressurewasher could

damageit and shorten its life.
