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.

Pressure Washer Operation
WARNING: Eye protection / Fluid Injection hazard
ALWAYS wear approved safety glasses when operating Pressure
Washers. Spray can splash back or propel objects, including incorrectly
attached accessories. The high-pressure stream of water that this equipment produces
can cut through skin and its underlying tissues, leading to possible amputation. The
spray gun traps high water pressure, even when the motor is stopped and water source
is disconnected, which can cause injury.
• Do not direct spray from the Pressure Washer at any persons or animals.
Keep children and pets away from the work area.
Keep work area clean of loose rocks, glass and debris.
The high pressure water stream could cause serious injury.
•
•
•
WARNING: Asphyxiation Hazard
Use the Pressure Washer only outside in a fully ventilated area.
• Operate this product ONLY outside far away from windows, doors and vents.
• DO NOT run this product inside homes, garages, basements, crawlspaces, or sheds.
• 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.
1. Selecting the Right Nozzle for the job.
Your product is supplied with a selection
of quick connect nozzle tips. The nozzles
are sized specifically to give you maximum
pressure at all times. Each nozzle is
marked and rated in degrees of fan. They
are also color coded (see chart on opposite
page). The higher the number of the fan
degree, the wider the fan pattern is. The
tighter the spray fan the more impact on
the surface, which is good for cleaning
tough jobs. The wider the spray fan, the
more spread out the impact on the surface,
so they are better for easy jobs, or soft
surfaces. Finding the correct nozzle for the
job at hand make take some experimenting.
Always start with the widest fan degree and
continue to the lower degree fans until the
best work result is achieved. Always test
the nozzle on an area that is not noticeable.
NOTICE: Not all models come with all nozzles described in this section. Use only the
information pertaining to the nozzles supplied with your product.
(Nozzle selection Chart)

0° Nozzle . Red: This nozzle delivers a pinpoint stream of pressurized water and is
extremely powerful. Use it for the toughest cleaning jobs, although It covers only a
small area. This nozzle should only be directed at surfaces that can withstand intense
high pressure such as metal or concrete. Do not use this nozzle to clean wood or soft
surfaces.
25° Nozzle - Green: This nozzle delivers a 25-degree spray pattern for general tasks. It
should only be used on surfaces that can withstand pressure from this nozzle.
65° Chemical Nozzle - Black: This nozzle is used to apply special chemicals and
cleaning solutions. This nozzle produces the weakest pressure stream of the nozzles.

in contact with engine exhaust system
which can cause damage to the hose.
Damaged hoses can burst and can
cause injection injuries.
4.6
For most effective cleaning, keep
spray nozzle from 8 to 24 inches
away from cleaning surface. If you
get spray nozzle too close, you may
damage surface being cleaned. It is
not recommended to get closer than 6
inches when cleaning tires.
5. Pressure Adjustment
5.1 Vary your distance: To change the
effect of the pressure on the surface
being cleaned, vary the distance
between spray nozzle and the surface
being cleaned. The closer to the
surface the higher the effect of the
pressure. As you pull away from
the surface, the pressure effect will
reduce. For most effective cleaning,
keep the nozzle between 8 to 24
inches from surface being cleaned.
6.Using Chemicals
NOTICE: Use only soaps and chemicals
designed for use with a Pressure Washer.
DO NOT USE CHLORINE BLEACH,
ACIDS OR INDUSTRIAL SOLVENTS.
Chemicals, soaps and cleaning solvents
will not siphon when a high-pressure nozzle
is used. Only use the Black (low pressure)
Nozzle when spraying detergents. Fill
Detergent Tank (if so equipped) with
prepared detergent solution and close the
cap. The Pressure Washer will draw one
gallon of detergent for every seven gallons
of water.
