Important Operation Instructions and Precautions:
DANGER: POISONOUS GAS HAZARD
Engine exhaust contains carbon monoxide, a poisonous gas that WILL kill you
in minutes. You CANNOT smell it, see it, or taste it. Even if you do not smell
exhaust fumes, you could still be exposed to carbon monoxide gas. Some chemicals or
detergents could also be harmful if inhaled or ingested, resulting in death, serious injury,
nausea, fainting or poisoning.
• Operate this product ONLY outside far away from windows, doors and vents to
reduce the risk of carbon monoxide gas from accumulating and potentially being
drawn towards occupied spaces.
• DO NOT run this product inside homes, garages, basements, crawlspaces, sheds, or
other partially enclosed spaces, even if using fans or opening doors and windows for
ventilation. Carbon monoxide can quickly build up in these spaces and can linger for
hours, even after this product has been shut off.
• ALWAYS place this product downwind and point the engine exhaust away from
occupied spaces.
If you start to feel sick, dizzy, or weak while using this product, shut it off and get to
fresh air RIGHT AWAY. See a doctor, as you may have carbon monoxide poisoning.

WARNING: Fire / Hot Surface Hazard
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (1.5 m) of clearance on all sides of pressure washer including
overhead.
• Replacement part must be the same and installed in the same position as the original.
WARNING: Slip or Fall Hazard
Use of pressure washer
could create slippery
surfaces causing you to fall resulting in
death or serious injury.
• Kickback from spray gun could cause
you to fall resulting in death or serious
injury.
• Operate pressure washer from a
stable surface.
• The cleaning area should have
adequate slopes and drainage to
reduce the possibility of a fall due to
slippery surfaces.
• Be extremely careful if you must use
the pressure washer from a ladder,
scaffolding, or any other similar
location.
• Firmly grasp spray gun with both
hands when using high pressure
spray to avoid injury when spray gun
kicks back.
WARNING: Kickback Hazard
Starter cord kickback (rapid
retraction) will pull hand and
arm toward engine faster than you can
let go, which could cause fractures,
bruises, or sprains resulting in serious
injury.
•
NEVER pull starter cord without first
relieving spray gun pressure.
When starting engine, pull cord slowly
until resistance is felt and then pull
rapidly to avoid kickback.
After each starting attempt, where
engine fails to run, always point spray
gun in safe direction, disengage trigger
lock and squeeze spray gun trigger to
release high pressure.

WARNING: Fire / Explosion Hazard
Fuel and its vapors are extremely flammable and explosive which could
cause burns, fire or explosion resulting in death or serious injury.
Risk of fire and serious burns: Never remove fuel cap when unit is running. Shut off
engine and allow the unit to cool at least five minutes. Remove cap slowly.
WHEN ADDING OR DRAINING FUEL
• Turn pressure washer engine OFF and let it cool at least 2 minutes before removing
fuel cap. Loosen cap slowly to relieve any pressure remaining in tank.
• Fill or drain fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion.
• If fuel spills, wait until it evaporates before starting engine.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.
• Check fuel lines, tank, cap and fittings frequently for cracks or leaks. Replace if
necessary.
• DO NOT light a cigarette or smoke.
WHEN STARTING EQUIPMENT
• Ensure spark plug, muffler, fuel cap, and air filter are in place.
• DO NOT crank engine with spark plug removed.

WARNING: Fluid Injection
The high-pressure 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.
• If cut by fluid, call physician
immediately. DO NOT treat as a
simple cut.
• DO NOT allow CHILDREN to operate
pressure washer.
• NEVER repair high pressure hose.
Replace it.
• NEVER repair leaking connections
with sealant of any kind. Replace
o-ring or seal.
• NEVER connect high pressure hose
to nozzle extension.
• Keep high pressure hose connected
to pump and spray gun while system
is pressurized.
• ALWAYS point spray gun in safe
direction, disengage trigger lock and
squeeze spray gun trigger to release
high pressure, every time you stop
engine.
• NEVER aim spray gun at people,
animals, or plants.
• DO NOT secure spray gun in open
position.
• DO NOT leave spray gun unattended
while machine is running.
• NEVER use a spray gun which does
not have a trigger lock or trigger guard
in place and in working order.
