SAFETY RULES

CAUTION! When setting up, transporting,

adjusting or making repairs to your high pressure
washer, always disconnect the spark plug wire from
the spark plug and place the wire where it cannot
contact spark plug.

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.

Read this manual carefully and become familiar
with your pressure washer. Know its applications,
its limitations, and any hazards involved.

• Locate this pressure washer in areas away from
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 property damage or
severe injury.

• Do Not allow CHILDREN to operate the pressure
washer at any time.

The engine exhaust from this product

contains chemicals known to the State

of California to cause cancer, birth

defects, or other reproductive harm.

WARNING:

Generac Portable Products 3,000 PSI High Pressure Washer

• 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
increase or decrease 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.

• Never operate units with broken or missing parts, or
without protective housing or covers.

• 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 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.

• 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 by–pass 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.

• Operate and store this unit on a stable surface.

• 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 meets 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 arrestor 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 arrestor, it
must be maintained in effective working order. You can
order a replacement spark arrestor through your
authorized Honda service dealer.

• Add oil to the engine.

• Add fuel to the fuel tank.

• Secure handle to the pressure washer using the four
provided flange nuts.

• Slowly tip the pressure washer back in place and insert
the multi–colored nozzles in the spaces provided in the
handle.

Add Engine Oil

Place the unit on a flat, level surface. See engine owner’s
manual for proper oil and fill technique.

NOTE: The pump is pre-lubricated and sealed, requiring
no additional lubrication for the life of the pump.

Add Gasoline

DANGER! 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 clean regular unleaded fuel 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 the area around the fuel fill cap, remove the cap.
Slowly fill tank to the bottom of the filler neck (Figure 2).

• Install the fuel cap and wipe up any spilled gasoline.

Connect Hose and Water Supply to

Pump

IMPORTANT: You must assemble the nozzle extension

to the spray gun and attach all hoses before you start the
engine. Starting engine without all hoses connected and
water supplied will damage the pump.

• Uncoil high pressure hose and attach quick connect end
of hose to the base of the spray gun (Figure 3). Pull
down on the collar of the quick connect, slide onto the
gun and let go of collar. Tug on hose to be sure of a tight
connection.

• Similarly, attach the other end of the high pressure hose
to the high pressure outlet on the pump. Pull down on
the collar of the quick connect, slide onto the pump and
let go of collar. Pull on hose to be sure of a tight
connection.

• Before you connect your garden hose to the water inlet,
inspect the inlet screen (Figure 4). Clean the screen if it
contains debris, replace it if it is damaged. DO NOT
RUN THE PRESSURE WASHER IF THE SCREEN IS
DAMAGED.

• Run water through your garden hose for 30 seconds to
clean out any debris. Turn off water.

Inspect inlet screen. Do Not
use if damaged, clean if dirty.
