EQUIPMENT
DESCRIPTION
Read this manual carefully and become familiar
with your pressure washer. Know its applications,
its limitations and any hazards involved.
Every effort has been made to ensure that information in
this manual is accurate and current. However, Generac
reserves the right to change, alter or otherwise improve the
product and this document at any time without prior notice.
SAFETY RULES
The safety alert symbol ( ) is used with a signal word
(DANGER, CAUTION, WARNING), a pictorial and/or a
safety message to alert you to hazards. 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, might
result in minor or moderate injury. CAUTION, when
used without the alert symbol, indicates a situation that
could result in equipment damage. Follow safety messages
to avoid or reduce the risk of injury or death.
WHEN ADDING FUEL
• Turn pressure washer OFF and let it cool at least 2 minutes
before removing gas cap.
• Fill fuel tank outdoors.
• Do not overfill tank. Allow space for fuel expansion.
• Keep gasoline away from sparks, open flames, pilot lights, heat,
and other ignition sources.
• Do not light a cigarette or smoke.
WHEN OPERATING EQUIPMENT
• Do not tip engine or equipment at angle which causes
gasoline to spill.
• Do not spray flammable liquids.
WHEN TRANSPORTING OR REPAIRING EQUIPMENT
• Transport/repair with fuel tank EMPTY or with fuel shutoff
valve OFF.
WHEN STORING GASOLINE OR EQUIPMENT WITH
FUEL IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers or other appliances that have pilot light or other
ignition source because they can ignite gasoline vapors.
Gasoline and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• Never aim the spray gun at people, animals or plants.
• Do not allow CHILDREN to operate the pressure washer.
• Never repair high pressure hose. Replace it.
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
WARNING
• Keep water spray away from electric wiring or fatal electric
shock may result.
Spray contact with electrical wiring can result in
electrocution.
WARNING
In the State of California a spark arrester is required by law
(Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply on
federal lands. If you equip the muffler with a spark arrester,
it must be maintained in effective working order.
The engine exhaust from this product contains
chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
WARNING

• Operate pressure washer ONLY outdoors.
• Use a respirator or mask whenever there is a chance that
vapors may be inhaled.
• Read all instructions with mask so you are certain the mask will
provide the necessary protection against inhaling harmful vapors.
Running engine gives off carbon monoxide, an
odorless, colorless, poison gas.
Some chemicals or detergents may be harmful if
inhaled or ingested, causing severe nausea,
fainting or poisoning.
Breathing carbon monoxide will cause nausea,
fainting or death.
DANGER
• Do not touch hot surfaces.
• Allow equipment to cool before touching.
Running engines produce heat. Temperature of
muffler and nearby areas can reach or exceed
150°F (65°C).
Severe burns can occur on contact.
WARNING
• Keep spray nozzle between 8 to 24 inches away from cleaning
surface.
• Be extremely careful if you must use the pressure washer from
a ladder, scaffolding or any other relatively unstable location.
• The cleaning area should have adequate slopes and drainage to
reduce the possibility of a fall due to slippery surfaces.
• Operate this unit on a stable surface.
The high pressure spray could also cause you to
fall if you are too close to the cleaning surface.
Pressure in a running washer builds as you
climb. When you press the trigger, the recoil
from the initial spray could cause you to fall.
Use of pressure washer can create puddles and
slippery surfaces.
WARNING
• Do not tamper with governed speed.
• Do not operate the pressure washer above the rated pressure.
Excessively high or low operating speeds increase risk
of injury and damage to pressure washer.
CAUTION
• Do not point spray gun at glass when in the jet spray mode.
• Never aim the spray gun at plants.
High pressure spray may damage fragile items including
glass.
CAUTION
• Do not wear loose clothing, jewelry or anything that may be
caught in the starter or other rotating parts.
• Tie up long hair and remove jewelry.
Starter and other rotating parts can entangle
hands, hair, clothing, or accessories.
WARNING
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR
PRESSURE WASHER
• Disconnect the spark plug wire from the spark plug and place
the wire where it cannot contact spark plug.
Unintentional sparking can result in fire or
electric shock.
WARNING
• Always wear eye protection when you use this equipment or
when you are in the vicinity where the equipment is in use.
High pressure spray can cause paint chips or
other particles to become airborne.

• Place the handle onto the handle supports already
connected to the main unit. Make sure the holes in the
handle align with the holes on the handle supports

• Insert the carriage bolt through the right hole (facing the
front of the unit) and attach a plastic knob. Tighten by
hand (Figure 2).
• Insert the wire support with the longer arm positioned
on the left. From the rear of unit, the hook should
resemble a “J” (Figure 3).
Add Engine Oil
IMPORTANT: Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine failure.
• Place pressure washer on a level surface.
• Refer to the engine owners manual to add recommended
oil to engine.
NOTE: Check oil often during engine break–in. Refer to
engine owner’s manual for recommendations.
Add Gasoline
WARNING! Never fill fuel tank indoors. Never
fill fuel tank when engine is running or hot. Do Not
smoke when filling fuel tank.
WARNING! Never fill fuel tank completely full.
Provide space for fuel expansion. Wipe away any
fuel spillage from engine and equipment before
starting.
•
Use fresh, clean unleaded automotive gasoline and store in
approved, clean, covered containers. Use clean fill
funnels. Never use “stale” gasoline left over from last
season or gasoline stored for long periods.
• Clean area around fuel fill cap, remove cap.
• Slowly add "UNLEADED" regular gasoline to fuel tank.
Use a funnel to prevent spillage. Slowly fill tank to about
1.5" below the bottom of the filler neck (Figure 4).
• Install fuel cap and wipe up any spilled gasoline.
Connect Hose and Water Supply to
Pump
IMPORTANT: You must attach all hoses before you start
the engine. Starting engine without all hoses connected and
water supplied will damage the pump.
• Uncoil the high pressure hose and attach one end of the
hose to the base of the spray gun (Figure 5). Tighten by
hand.
