WARNING
Incorrect fuels shall not be used as they
may prove hazardous.
Fueling Instructions
WARNING
Fuel your pressure washer in well-
ventilated areas, outdoors. Always shut
off the engine and allow it to cool before
refueling. Gasoline vapor pressure may
build up inside the fuel tank depending
on the fuel used, the weather conditions
or other environmental conditions and
the use of the machine.
In order to reduce the risk of burns and
other personal injury from escaping gas
vapor and fumes, remove the fuel filler
cap on your pressure washer carefully
so as to allow any pressure build-up in
the tank to release slowly. Never remove
the fuel filler cap while the engine is
running.
Select bare ground for fueling and move
at least 10 feet (3 m) from the fueling
spot before starting the engine. Refuel
slowly. Avoid spilling fuel. Wipe off any
spilled fuel before starting your machine.
Gasoline is an extremely
flammable fuel. If spilled
and ignited by a spark or
other ignition source, it
can cause fire and seri
-
ous burn injury or
property damage. Use
extreme caution when
handling gasoline or fuel
mix. Do not smoke or
bring any fire or flame
near the fuel or the pres
-
sure washer. Note that
combustible fuel vapor
may escape from the fuel

thermal pressure relief valve, which
automatically lets hot water escape from
the high-pressure pump. Never use
water with a temperature more then
52 °C (125 °F) to run the pressure
washer. See the "Working" Chapter in
this manual for more information to the
thermal pressure relief valve.
Always comply with the water supply
requirements in the "Specifications"
chapter in this manual.
NOTICE
Insufficient water supply can damage
the high-pressure pump. Only start the
engine when the water hose is
connected and the water supply is
turned on and delivering the minimum
water requirements in the
"Specifications" chapter in this manual.
