DANGER! Engine exhaust gases contain
DEADLY carbon monoxide gas. This dangerous
gas, if breathed in sufficient concentrations, can
cause unconsciousness or even death. Operate
this equipment only in the open air where
adequate ventilation is available.
DANGER! Gasoline is highly FLAMMABLE
and its vapors are EXPLOSIVE. Do Not permit
smoking, open flames, sparks or heat in the
vicinity while handling gasoline. Avoid spilling
gasoline on a hot engine. Allow unit to cool for
2 minutes before refueling. Comply with all laws
regulating storage and handling of gasoline.

combustible materials, combustible fumes or dust.
The high pressure equipment is designed to be
used with Generac authorized parts ONLY. If you
use this equipment with parts that do not comply
with minimum specifications, the user assumes all
risks and liabilities.
Some chemicals or detergents may be harmful if
inhaled or ingested, causing severe nausea, fainting
or poisoning. The harmful elements may cause

defects, or other reproductive harm.
WARNING:
Generac Portable Products 3,000 PSI High Pressure Washer
3
Operate engine only at governed speed. Running
the engine at excessive speeds increases the
hazard of personal injury. Do Not tamper with parts
which may change the governed speed.
Do Not wear loose clothing, jewelry or anything that
may be caught in the starter or other rotating parts.
Before starting the pressure washer in cold weather,
check all parts of the equipment and be sure ice has
not formed there.
Never use a spray gun which does not have a
trigger lock or trigger guard in place and in working
order.
Keep the hose connected to machine or the spray
gun while the system is pressurized. Disconnecting
the hose while the unit is pressurized is dangerous.
Units with broken or missing parts, or without
protective housing or covers, should NEVER be
operated.
Check the fuel system for leaks or signs of
deterioration, such as chafed or spongy hose, loose
or missing clamps, or damaged tank or cap. Correct
all defects before operating the pressure washer.
Do Not spray flammable liquids.
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.
Never aim the spray gun at people, animals or
plants. The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
Never allow any part of the body to come in contact
with the fluid stream. Do Not come in contact with a
fluid stream created by a leak in the high pressure
hose.
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.
Do Not operate the pressure washer above the
rated pressure.
Never move the machine by pulling on the high
pressure hose. Use the handle provided on the unit.
Operate and store this unit on a stable surface.
Always be certain the spray gun, nozzles and
accessories are correctly attached.
Do Not secure the spray gun in the (open) position.
High pressure spray may damage fragile items
including glass. Do Not point spray gun at glass
when in the jet spray mode.
Hold the spray gun firmly in your hand before you
start the unit. Failure to do so could result in an
injury from a whipping spray gun. Do Not leave the
spray gun unattended while the machine is running.
The cleaning area should have adequate slopes and
drainage to reduce the possibility of a fall due to
slippery surfaces.
Keep water spray away from electric wiring or fatal
electric shock may result.
Do Not bypass any safety device on this machine.
The muffler and engine heat up during operation
and remain hot immediately after shutting it down.
Avoid contact with a hot muffler or engine as you
could be severely burned.
High pressure hose can develop leaks from wear,
kinking, abuse, etc. Water spraying from a leak is
capable of injecting material into skin. Inspect hose
each time before using it. Check all hoses for cuts,
leaks, abrasions or bulging of cover, or damage or
movement of couplings. If any of these conditions
exist, replace hose immediately. Never repair high
pressure hose. Replace it with another hose that
exceeds maximum pressure rating of your unit.
The muffler and air cleaner must be installed and in
good condition before operating the pressure
washer. These components act as spark arresters if
the engine backfires.
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.
NOTE: If you equip the muffler with a spark arrester, it
must be maintained in effective working order. You can
order a spark arrester through your authorized Honda
service dealer.
