After Each Use - Briggs & Stratton PowerBoss Operator's Manual

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 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. Flush detergent system by turning its cleaning tanks
shut-off valves to "Off" position and run pressure
washer with black spray tip. Flush for one to two
minutes.

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
attached to 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,
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.
