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.
Locate this pressure washer in areas away from com-
bustible materials, combustible fumes or dust.
The high pressure equipment is designed to be used with Gen-
erac 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 protec-
tive housing or covers should NEVER be operated.
The muffler and air cleaner must be installed and in good con-
dition before operating the Pressure Washer. These
components act as spark arrestors if the engine backfires.
Check the fuel system for leaks or signs of deterio-
ration 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.
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 equip-
ment 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 acces-
sories 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
mask so you are certain the mask will provide the necessary protection against inhaling harmful vapors.
High pressure spray may damage fragile items includ-
ing glass. Do not point spray gun at glass when in the
jet spray mode.
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.
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 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.
High pressure hose can develop leaks from wear, kinking,
abuse, etc. Water spraying from a leak is capable of inject-
ing 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 condi-
tions exist, replace hose immediately. Never repair high
pressure hose. Replace it with another hose that meets min-
imum pressure rating of your pressure washer.
The engine exhaust from this product
contains chemicals known to the State
of California to cause cancer, birth
defects, or other reproductive harm.

PREPARING THE PRESSURE

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 top of the handle onto the bottom of the
handle already connected to the main unit making
sure the holes in the top align with the holes on the
bottom. (Figure 1)

Insert the carriage bolt through the right hole (look-
ing at the front of the pressure washer) and attach a
plastic knob. Tighten the knob by hand (Figure 2).
Insert the carriage hook through the left hole (look-
ing at the front of the pressure washer). Pull the
recoil handle out slowly. Place the recoil string
through the hook and attach the plastic knob.
Tighten the knob 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
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.
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 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.
Figure 3 Fit wire form on handle.
Figure 4 Add oil to engine crankcase. Do not
attempt to start engine without
adding oil.

The manufacturer recommends fresh, clean unleaded
automotive gasoline.
Use clean fuel and store in approved, clean, cov-
ered 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 (see Figure 8). Clean
the screen if it contains debris or have it replaced if
damaged. DO NOT RUN THE PRESSURE
WASHER IF THE SCREEN IS DAMAGED.
Connect garden hose to water inlet. Tighten by
hand. (Figure 8)
Turn ON the water (open valve completely).
Squeeze trigger on gun to purge pump system of
air and impurities.
CAUTION: Before starting the pressure
washer, be sure you are wearing adequate eye protection.
