SAFETY RULES
DANGER! Always disconnect spark plug
wire and place wire where it cannot
contact spark plug to prevent accidental
starting when setting up, transporting,
adjusting or making repairs to your high
pressure washer.
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.
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.
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.
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.
Units with broken or missing parts, or without
protective housing or covers should NEVER be
operated.
The muffler and air cleaner must be installed
and in good condition before operating the
Pressure Washer. These components act as
spark arrestors if the engine backfires.
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.
Never aim the gun at people, animals or
plants.
High pressure spray can cause paint chips or
other particles to become airborne and fly at
high speeds.
The engine exhaust from this product
contains chemicals known to the State
of California to cause cancer, birth
defects, or other reproductive harm.

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.
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury
and possible amputation.
Always wear eye protection when you use this
equipment or when you are in the vicinity
where the equipment is in use.
Never move the machine by pulling on the high
pressure hose. Use the handle provided on the
top of the unit.
Always be certain the spray gun, nozzles and
accessories are correctly attached.
Never use a spray gun that does not have a
trigger lock or trigger guard in place and in
working order.
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.
High pressure spray may damage fragile items
including glass. Do not point spray gun at glass
when in the jet spray mode.
Keep all hoses connected to pressure washer
and the spray gun while the system is
pressurized. Disconnecting the hoses while the
unit is pressurized is dangerous.
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 secure gun trigger in the pullback
(open) position.
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 or 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
pressure washer.

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.
Note: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF,SG, SH or SH/CD rated SAE 30
weight.
Select the oils viscosity grade according to your
expected operating temperature:
Do Not Use SAE 10W40 Oil.
Although multiviscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multiviscosity
oils will result in increased oil consumption when used
above 32°F. Check your engine oil level more
frequently to avoid possible damage from running low
on oil.
Place pressure washer on a level surface.
Clean area around oil fill and remove oil dipstick
(Figure 4).
Wipe dipstick clean. Pour oil into oil fill opening until
oil reaches FULL mark on the dipstick. Stop
occasionally to check oil level. DO NOT OVERFILL.
Install oil dipstick, hand tighten securely.
Note: Check Oil Often During Engine Breakin.

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. Fill tank to about 1/2" below the bottom of
the filler neck to provide space for fuel
expansion. Wipe away any fuel spillage from
engine and equipment before starting.
The manufacturer recommends fresh, clean unleaded
automotive gasoline.
Use clean 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 area around fuel fill cap, remove cap.
(Figure 5).
Add UNLEADED regular gasoline, slowly, to fuel
tank. Use a funnel to prevent spillage.
Install fuel cap and wipe up any spilled gasoline.
Connect Hose and Water Supply
to Pump
IMPORTANT: You must assemble wand and attach
all hoses before you start engine. Starting engine
without all hoses connected and water supplied will
damage pump.
Uncoil high pressure hose and attach one end of
hose to the base of the spray gun (Figure 6).
Tighten by hand.
Attach other end of high pressure hose to the high
pressure outlet on the pump (Figure 7). Tighten by
hand.
Before you connect your garden hose to the water
inlet, inspect the Inlet Screen (Figure 8). Clean the
screen if it contains debris or have it replaced if
damaged. Do not run the pressure washer if the
inlet screen is damaged.
Connect garden hose to water inlet. Tighten by
hand (Figure 8).
