Carburetor Adjustment; After Each Use - Briggs & Stratton 80018646 Manual Del Operador

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 or serious injury.
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 ft. (1.5 m) 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 service dealer clean the cooling system per
recommended intervals (see Maintenance Schedule in
beginning of Maintenance section). 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.
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. Flush detergent from pump by running pressure
washer for one to two minutes with a high pressure
spray tip.
2. 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.
3. Disconnect hose from spray gun and high
pressure outlet on pump. Drain water from hose,
spray gun, and nozzle extension. Use a rag to
wipe off the hose.
4. Place the spray gun, nozzle extension and spray
tips in the accessory tray. Hang high pressure
hose on hook of accessory tray.
5. Empty pump of all pumped liquids by pulling recoil
handle about six times. This should remove most
liquid in pump.
6. Store unit in a clean, dry area.
7. 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 or serious injury.
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.
