Craftsman 580.751781 - Manual (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.
Test the pressure washer by operating with nozzle in
the high and in the low position.
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.
A CAUTION: BE SURE THE THROTTLE LEVER IS IN
“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
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.
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.
A CAUTIONI AVOID SPRAY FROM SPARK PLUG
HOLE WHEN CRANKING ENGINE SLOWLY.
If you do not plan to use the Pressure Washer for more than
30 days, you must prepare the engine for long term storage.
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.
