Craftsman 580.752840 Operator's Manual page 22

Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect for
damage or carbon blockage. If replacement parts are required,
make sure to use only original equipment replacement parts.
WARNING Exhaust heat/gases could ignite
combustibles, structures or damage fuel
tank causing a fire, resulting in death,
serious injury and/or property damage.
Contact with muffler area could cause burns resulting in
serious injury.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (152 cm) of clearance on all sides of
pressure washer including overhead.
• It is a violation of California Public Resource Code, Section
4442, to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land unless the exhaust
system is equipped with a spark arrester, as defined in Section
4442, maintained in effective working order. Other states or
federal jurisdictions may have similar laws.
Contact the original equipment manufacturer, retailer, or dealer
to obtain a spark arrester designed for the exhaust system
installed on this engine.
• Replacement parts must be the same and installed in the same
position as the original parts.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a qualified Sears
service dealer clean the cooling system per recommended
intervals (see Maintenance Schedule). Equally important is to
keep top of engine free from debris. See Clean Debris.
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve. Top speed has been
set at the factory. If adjustment is required, see an authorized
service dealer.
CAUTION Excessively high operating speeds could
result in minor injury and/or pressure washer damage.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governor spring, links or other parts to
increase engine speed. Pressure washer supplies correct rated
pressure and flow when running at governed speed.
• DO NOT modify pressure washer in any way.
AFTER EACH USE
Water should not remain in the unit for long periods of time.
Sediments or minerals can deposit on pump parts and
"freeze" pump action. Follow these procedures after every
use:
1. Shut off engine, turn off water supply, point gun in a
safe direction, press red button and squeeze trigger to
relieve trapped pressure and let engine cool.
WARNING The high pressure stream of water that
this equipment produces could cut through skin
and its underlying tissues, resulting in serious
injury and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which could result in
serious injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction, press red button
and squeeze spray gun trigger to release high pressure, every
time you stop engine.
2. Disconnect hose from spray gun and high pressure
outlet on pump. Drain water from hose, gun, and nozzle
extension. Use a rag to wipe off the hose.
3. Empty pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most liquid in
pump.
4. Coil high pressure hose on hook provided on handle.
5. Store unit in a clean, dry area.
6. If storing for more than 30 days see Long Term Storage
on next page.
WARNING Fuel and its vapors are extremely flammable
and explosive which could cause burns,
fire or explosion resulting in death,
serious injury and/or property damage.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers, or other appliances that have pilot light or other ignition
source because they could ignite fuel vapors.
