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
A
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 for five min­
utes.
o Shut off the engine and let it cool, then remove all
hoses.
...... CAUTION: BE SURE THE THROTTLE LEVER IS IN
"STOP" POSITION BEFORE YOU CONTINUE. IF
YOU START THE ENGINE WITHOUT THE PROPER
WATER SUPPLY CONNECTED, YOU CAN DAM-
AGETHE PUMP.
_______________
e Empty the pump of alt pumped liquids by pulling recoil
handle about 6 times . This should remove most of the
liquid in the pump.
<» Coll the high pressure hose and Inspect it for damage.
Cuts in the 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 connected to the inlet
adapter and pulling the recoil handle twice.
« Store in a clean, dry area.
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 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
instriictions:
A WARNING: NEVER STORE ENGINE WITH FUEL IN
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
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.
o For engine protection use a fuel stabilizer (such as
STA-BIL®). Mix stabilizer with fuel in fuel tank and run
engine for short time to circulate stabilizer through
caiburetor.
o If you did use “gasohol”, mn 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
}lug hole with rag. Crank slowly to distribute oil
A CAUTION I AVOID SPRAY FROM SPARK PLUG
HOLE WHEN CRANKING ENGINE SLOWLY.
• Install spark plug. Do not connect spark plug wire.
OTHER
o Do not store gasoline from one season to another
o Replace your gasoline can if your can starts to rust.
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.
• Cover your unit with a suitable protective cover that
does not retain moisture.
