CAUTION: 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.
Use 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.
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.
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury.
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.

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 which 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 the mask so you are certain it
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 high pressure spray mode.
Keep the hose connected to machine and the
spray gun while the system is pressurized.
Disconnecting the hose while the unit is
pressurized is dangerous.
Hold the spray gun firmly in your hands 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 trigger gun in the pull-back (open)
position.
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 or you
could be severely burned.
Operate and store this unit on a stable surface.
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.
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 minimum pressure rating
of your pressure washer.

PREPARING THE
PRESSURE WASHER
FOR USE
If you have any problems with the assembly of your
pressure washer or if parts are missing or damaged,
call the Pressure Washer Helpline at 1-800-270-1408.
To prepare your pressure washer for operation you
will need to perform these tasks:
Attach the handle and attach the wire form that
holds high pressure hose and spray gun.
Connect high pressure hose to the spray gun and
the pump and connect water supply to the pump.
Add oil to engine crankcase.
Add fuel to fuel tank.
Attach the Handle
Place the handle onto the bottom the handle
supports already connected to the main unit. Make
sure the holes in the handle align with the holes in
the handle supports (Figure 1).
Note: It may be necessary to move the handle
supports from side to side in order to align the handle
so it will slide over the handle supports.
Figure 1 — Attach the top of the handle to the
bottom of the handle.
Make sure
the holes in
the handle

ASSEMBLY
Insert the carriage bolts from the outside through
the holes on the handle and attach the plastic
knobs on the inside. Tighten the knobs by hand
(Figure 2).
Insert the wire support with the longer arm positioned
on the left. From this view (from rear of unit), the hook
resembles a J

Add Engine Oil
IMPORTANT: Any attempt to crank or start the
engine before being properly serviced with the
recommended oil will 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 multi-viscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multi-viscosity
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 yellow oil fill
cap (Figure 4).
Pour oil into the oil fill opening until it reaches the
top of the oil fill hole. DO NOT OVERFILL.
Install yellow oil cap, 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 containers.
Use clean fill funnels. Never use stale gasoline
left over from last season or gasoline stored for long
periods.
Figure 3 — Fit wire form on handle.
Figure 4 — Add oil to engine crankcase. Do not
attempt to start engine without
adding oil.

without all hoses connected and water supplied will
damage pump.
Uncoil high pressure hose and attach the end of the
hose with the threaded end 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
