BEFORE STARTING THE ENGINE

To operate the engine you will need the following:

ENGINE OIL

IMPORTANT: ANY ATTEMPT TO CRANK OR START

THE ENGINE BEFORE iT HAS BEEN PROPERLY SERV-

ICED WITH THE RECOMMENDED OIL RESULTS IN AN
ENGINE FAILURE,

A 27 oz.,bottle of SAE 30 weight oil is included in the parts
carton,,

OPERATION

NOTE: When adding oil to the engine crankcase in the
future, use only high quality detergent oil rated with API

service classification SF, SG or SH rated SAE 30 weight.
Use no special additives. Select the oil's viscosity grade

according to your expected operating temperature.

Although mutti-viscosity oils (5W30, 10W30, etc.) improve

starting in coldweather, these multi-viscosityoils will result
in increased oil consumption when used above 32°F.

Check your engine oil level more frequently toavoid possi-
ble damage from running low on oiloOil sump capacity is

20 ounces.

• Position pressure washer so engine islevel.
. Clean area around oil fill plug and remove oil fill plug

(Fig. 18)_.

I_G. 18

° Fill oil crankcase to point of overflowing. Oil sump

capacity is 20 U.S_ ounces..

IMPORTANT: THE MOTOR OIL INCLUDED IN THE
CARTON CONTAINS 27 OUNCES. IT IS NOT NECES-

SARY TO USE THE ENTIRE AMOUNT OF OIL IN THE
OIL CONTAINER°

IMPORTANT: IT IS IMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYS-
TEM PARTS SUCH AS THE CARBURETOR, FUEL FIL-

TER, 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 SYS-

TEM OF AN ENGINE WHILE IN STORAGE. TO AVOID

ENGINE PROBLEMS, THE FUEL SYSTEM SHOULD BE
EMPTIED BEFORE STORAGE OF 30 DAYS OR

LONGER. SEE "STORAGE" ON PAGE 17. NEVER USE

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 these instructions:
, Shut off the engine and turn off the water supply,

° Separate the wand from the gun.
° Remove nozzle from the end of the wand using a 2mm

or 5/64 allen wrench (like the one included in the kit).

"freeze" pump action. Follow these procedures after every

use:

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 for five min-

utes,,
Shut off the engine and let it cool, then remove awl

hoses.

A CAUTION; BESURE THE THROTTLE LEVER ISIN

. "STOP" POSITION BEFORE YOU CONTINUE. IF

YOUSTART THE ENGINE WITHOUTTHE PROPER
WATER SUPPLY CONNECTED, YOU CAN DAM-
AGETHE PUMP.

o Empty the pump of all pumped liquids by pulling recoil

handle about 6 times, This should remove most ofthe

liquid in the pump.

o Coil the high pressure hose and inspect it for damage.

Cuts in the hose or fraying of itcould result in leaks and
loss ofpressure° 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_

LONG TERM STORAGE

WARNING: NEVER STORE ENGINEWITHFUEL IN

TANK INDOORS OR INENCLOSED, POORLYVEN-
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.

Ifyou do not plan to use the Pressure Washer for more than

30 days, you must prepare the engine for long term storage..

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 attractmoisture whichleads

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. Followthese
instructions:

Protect Fuel System: Engines stored over 30 days need
to be protected or drained of fuel to prevent gum deposits
from forming infuel system oron essential carburetor parts°

,, For engi,_e protection use a fuel stabilizer (such as

STA-BIL'_')oMix stabilizer with fuel in fuel tank and run
engine for short time to circulate stabilizer through

carburetor.

,_ If you did use "gasohot", run engine until engine stops

from lack of fuelo 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.

i _ CAUTION, AVOIDSPRAYFROM SPARKPLUG I

HOLE WHEN CRANKING ENGINE SLOWLY.

° Install spark plugo Do not connect spark plug wire.

OTHER

,_ Do not store gasoline from one season to another.
o Replace your gasoline can if your can starts to rusL

Rust and/or dirt in your gasoline will cause problems°

= If possible, store your unit indoors and cover it to give

protection from dust and dirt..

o Cover your unit with a suitable protective cover that

does not retain moisture°
