The safety alert symbol indicates a potential
personal injury hazard. A signal word (DANGER,
WARNING, or CAUTION) is used with the alert symbol
to designate a degree or level of hazard seriousness.
A safety symbol may be used to represent the type of
hazard. The signal word NOTICE is used to address
practices not related to personal injury.

DANGER indicates a hazard which, if not avoided,
will result in death or serious injury.

WARNING indicates a hazard which, if not
avoided, could result in death or serious injury.

CAUTION indicates a hazard which, if not
avoided, could result in minor or moderate injury.

NOTICE address practices not related to personal
injury.

WARNING POISONOUS GAS HAZARD.

Engine exhaust contains carbon monoxide,
a poisonous gas that could 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 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.

• Install battery-operated carbon monoxide alarms or
plug-in carbon monoxide alarms with battery back-up
according to the manufacturer’s instructions. Smoke
alarms cannot detect carbon monoxide gas.

• DO NOT run this product inside homes, garages,
basements, crawlspaces, sheds, or other partially­enclosed 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 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, get to fresh air RIGHT AWAY. See a doctor. You
may have carbon monoxide poisoning.

• Use a respirator or mask whenever there is a chance that
vapors may be inhaled when using chemicals.

• Read all instructions with mask so you are certain the
mask will provide the necessary protection against
inhaling harmful vapors when using chemicals.

• It is a violation of California Public Resource Code,
Section 4442, to use or operate the engine on any forest­covered, brush-covered, or grass-covered land unless
the exhaust system is equipped with a spark arrester, as
defined in Section 4442, maintained in effective working
order. Other states or federal jurisdictions may have
similar laws.

Contact the original equipment manufacturer, retailer,

or dealer to obtain a spark arrester designed for the
exhaust system installed on this engine.

• Replacement parts must be the same and installed in the
same position as the original parts.

WARNING Use of pressure washer could

create puddles and 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

Lubricate O-Rings

Lubrication of o-rings is extremely important for
installation and operation. The use of a lubricant
(petroleum or synthetic grease) during assembly helps
seat o-rings properly and provides an improved seal. It
also helps protect the o-ring from damage by abrasion,
pinching or cutting and extends the life of the o-ring.

NOTICE ALWAYS apply a small amount of lubricant
on o-rings prior to assembling the garden hose to the
pump (H), high pressure hose (J), spray gun (K), and
nozzle extension (L).

Lubricate all connections shown below, following
these instructions:

1. Inspect and clean connecting surfaces prior to

lubrication and assembly.

2. Use lubricants sparingly during assembly; a light

film is all that is required.

directly to o-rings where they are not accessible
(QC fitting, M22 fitting).
