GENERAL SAFETY RULES
!
DANGER
NEVER operate the pressure washer
in an enclosed area. Engine exhaust
contains carbon monoxide. Only
operate the pressure washer outside
and away from windows, doors and
vents.
!
WARNING
Gasoline and gasoline vapors are
extremely fl ammable and explosive
under certain conditions.
• ALWAYS refuel the pressure washer
outdoors, in a well-ventilated area.
• NEVER remove the fuel cap with the
engine running.
• NEVER refuel the pressure washer
while the engine is running. Always
turn engine off and allow the
pressure washer to cool before
refueling.
• Only fi ll fuel tank with gasoline.
• Keep sparks, open fl ames or other
form of ignition (such as match,
cigarette, static electric source) away
when refueling.
• NEVER overfi ll the fuel tank. Leave
room for fuel to expand. Overfi lling
the fuel tank can result in a sudden
overfl ow of gasoline and result in
spilled gasoline coming in contact
with HOT surfaces. Spilled fuel
can ignite. If fuel is spilled on the
pressure washer, wipe up any
spills immediately. Dispose of rag
properly. Allow area of spilled fuel
to dry before operating the pressure
washer.
• Wear eye protection while refueling.
• NEVER use gasoline as a cleaning
agent.
• Store any containers containing
gasoline in a well-ventilated area,
away from any combustibles or
source of ignition.
• Check for fuel leaks after refueling.
Never operate the engine if a fuel leak
is discovered.
!
WARNING
This equipment produces a stream
of water with enough high pressure
to penetrate skin and its underlying
tissues, which could result in
amputation or other serious injury.
Spray gun traps high-pressure water,
even when engine is stopped and
water is disconnected. Leaks caused
by loose fi ttings or worn or damaged
hoses can result in injection injuries.
DO NOT TREAT FLUID INJECTION
AS A SIMPLE CUT! See a physician
immediately!
• NEVER aim spray gun at people,
animals or plants. Direct spray away
from self and others.
• NEVER place hands in front of nozzle.
• ALWAYS point spray gun in safe
direction while spraying and when
relieving retained high pressure after
stopping engine.
• DO NOT allow CHILDREN to operate
pressure washer.
• NEVER leave spray gun unattended
while machine is running.
• NEVER secure spray gun in open
position.
• DO NOT twist nozzle while spraying.
• NEVER repair a high-pressure hose.
ALWAYS replace it.
• NEVER repair leaking connections
with sealant of any kind. ALWAYS use
factory-recommended repair parts.
• NEVER hold onto the hose or fi ttings
during operation.
• DO NOT allow high-pressure hose to
contact muffl er or other extremely
hot surfaces.
• ALWAYS be certain spray gun,
nozzles and hoses are correctly
attached and in working order.
• NEVER use spray gun if trigger lock
is not in working order.
• ALWAYS use spray gun, hoses and
connections rated for pressure
higher than your pressure washer’s
psi.
• NEVER attach or remove spray gun,
nozzles or hoses while system is
pressurized.

SAFETY
!
WARNING
• NEVER modify spray equipment.
• ALWAYS wear protective clothing to
protect eyes and skin from contact
with sprayed materials.
NEVER aim spray in the direction of
power source. Contact with power
source can cause electric shock or
burn.
Unexpected kickback while spraying
can cause you to fall.
• Use of pressure washer can create
slippery surfaces and puddles. The
operating area of this equipment
should have adequate drainage to
reduce the possibility of a fall due to
slippery surfaces.
• Be extremely careful if necessary
to use the pressure washer from
a ladder, scaffolding or any other
similar location.
• Use both hands to fi rmly gasp the
spray gun while in use to avoid injury
from high-pressure kickback.
NEVER use acids, toxic or corrosive
chemicals, poisons, insecticides, or
any kind of fl ammable solvent with
this equipment. Only use detergents,
cleaners and degreasers recommended
for use in this pressure washer.
ALWAYS wear chemical splash safety
goggles that comply with ANSI Z87.1
when operating or in the vicinity of this
equipment.
ALWAYS remove any tools or other
service equipment used during
maintenance from the pressure washer
before operating.
NOTICE
NEVER operate pressure washer with damaged or
missing parts.
NEVER modify any feature or component of pressure
washer.
NEVER spray at glass when using the high-pressure
nozzle (red). High-pressure spray may damage fragile
items including glass.
DO NOT exceed rated pressure when operating
pressure washer.
NEVER move pressure washer by pulling on any
hoses. Always use handle to move pressure washer.
Check components for ice forming on components
when operating in cold weather.
Remove the protective shipping caps from the pump’s
water inlet and outlet.
Be sure the water supply is connected and turned
on before starting the engine. Damage to the pump
could occur and will void the warranty.
Water supply must deliver a minimum of 3.8 gal
(14.3 L) per minute and at least 30 psi (2 bar). Do
not siphon standing water for the water supply. Water
temperature must not exceed 100°F (37.7°C).
DO NOT install a one-way valve, vacuum breaker or
check valve at the pump’s water inlet. Installing one of
these devices at the pump’s water inlet could cause
damage to the pump and will void the warranty. Allow
at least 10 feet (3 m) of unrestricted hose length
between the pump’s water inlet and a one-way valve,
vacuum breaker or check valve.
