WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could dam-
age the pump. Prepare detergent
solutionasrequired bythemanufac-
turer. Fill a container with pressure
washer detergent. Place the filter
end of detergent suction tube into
the detergent container.
STEP 2: Open detergent metering valve.
STEP 3: Detergentwill be drawn into
the pump and coil and discharged
under pressure. Never use anything
that will damage the pump and coil.
STEP 4: With the engine running,
pulltrigger to operatemachine.Liquid
detergent is drawn into the machine
and mixed with water. Apply detergent to work area.
Do not allow detergent to dry on surface.
IMPORTANT: You must flush the detergent from
your machine after each use by placing the suction
tube into a bucket of clean water and then running
the pressure washer for 1-2 minutes.
THERMAL PUMP
PROTECTION
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach high tem-
peratures. When the water reaches this temperature,
the pump protector engages and cools the pump by
discharging the warm water onto the ground. This
thermal device prevents internal damage to the pump.
CLEANINGTIPS
Pre-rinse cleaning surface with fresh water. Place de-
tergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
yourwork areatosections approximately6 feetsquare
and always apply detergent from bottom to top).Allow
detergent to remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. If surface appears
tobe drying, simply wetdown surfacewithfresh water.
If needed, use brush to remove stubborn dirt.Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
fromcleaning surface.Useoverlappingstrokesas you
clean and rinse any surface.For best surface cleaning
action spray at a slight angle.
Recommendations:
฀•฀Before cleaning any surface, an inconspicuous
areashouldbe cleaned to testspray patternand
distance for maximum cleaning results.
฀•฀฀If฀painted฀surfaces฀are฀peeling฀or฀chipping,฀use extreme caution as pressure washer may
remove the loose paint from the surface.
฀•฀฀Keep฀the฀spray฀nozzle฀a฀safe฀distance฀from฀the surface you plan to clean. High pressure
wash a small area, then check the surface for
damage. If no damage is found, continue to
pressure washing.
CAUTION - Never use:
฀•฀฀Bleach,฀chlorine฀products฀and฀other฀corrosive฀chemicals
฀•฀฀Liquids฀containing฀solvents฀(i.e.,฀paint฀thinner,฀gasoline, oils)
฀•฀฀Tri-sodium฀phosphate฀products฀•฀฀Ammonia฀products฀•฀฀Acid-based฀productsThese chemicals will harm the machine and will
damage the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desiredhigh pressure nozzle.NOTE:You can alsostop
detergent from flowing by simply removing detergent
siphon tube from bottle.

the spark plug hole, pull the starter grip several
times and replace the plug. Then pull the starter
grip slowly until you feel increased pressure which
indicatesthepiston is on itscompressionstrokeand
leave it in that position.This closes both the intake
and exhaust valves to prevent rusting of cylinder.
4. Cover pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks. NOTE:Use of a fuel additive, such as
STA-BIL®, or an equivalent, will minimizethe formu-
lationoffuel deposits duringstorage.Suchadditives
may beadded to the gasoline inthe fuel tank of the
engine, or to the gasoline in a storage container.
After Extended Storage
CAUTION:Prior to restarting,thaw out any
possible ice from pressure washer hoses,
spray gun or wand.
Engine Maintenance
During the winter months, rare atmospheric conditions
may develop which will cause an icing condition in the
carburetor. If this develops, the engine may run rough,
losepower and may stall.This temporary conditioncan
be overcome by deflecting some of the hot air from the
engine over the carburetor area. NOTE: Refer to the
engine manufacturer's manual for service and mainte-
nance of the engine.

MAINTENANCE AND SERVICE
UnloaderValves:
Unloader valves are preset and tested at the factory
before shipping.Occasional adjustment of the unloader
may be necessary to maintain correct pressure.
Adjusting UnloaderValves:
Tampering with the factory setting may cause
personal injury and/or property damage and will void
the manufacturer's warranty.
Winterizing Procedure:
Damage due to freezing is not covered by warranty.
Adheretothefollowingcoldweatherprocedures when-
ever the washer must be stored or operated outdoors
under freezing conditions.
During wintermonths,when temperatures drop below
32°F, protecting your machine against freezing is nec-
essary. Store the machine in a heated room. If this is
not possible then mix a 50/50 solution of anti-freeze
andwaterin the float tank.Turn the engine ontosiphon
the anti-freeze mixture through the machine. If com-
pressed air is available, an air fitting can be screwed
into the float tank by removing the float tank strainer
and fitting.Then inject the compressed air. Water will
be blown out of the machine when the trigger on the
spray gun is opened.
High Limit HotWaterThermostat:
For safety, each machine is equipped with a tem-
peraturesensitive highlimitcontrol switch.In theevent
thatthewatershould exceeditsoperatingtemperature,
the high limit control will turn the burner off until the
water cools then it will automatically reset itself. The
thermostat sensor is located on the discharge side of
the heating coil.The thermostat control dial is located
on the control panel.
Pumps:
Beforerunning thepumpcheckthepumpcrankcasefor
a proper oil level.A proper oil level is indicated by the
red dot in the sightglass or between the high and low
marks on thedipstick.Useonly SAE 30 non-detergent
oil. Change the initial oil after the first 50 hours and
then change the oil every 500 hours or every three
months.
Whendrainingoil,cleaninside of crankcase to remove
all impurities. CAUTION: When operating in damp
places or with high temperature fluctuations oil
must be changed immediately.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidlyinsidetheheating coil.Thisgrowthis increased
by the extreme heat build up in the coil. The best
preventative for liming conditions is to use high qual-
ity cleaning detergents.In areas where alkaline water
is an extreme problem, periodic use of Coil Condi-
tioner will remove lime and other deposits before coil
becomes plugged. (See Deliming instructions for use
of Coil Conditioner.)

MAINTENANCE
Deliming Coils:
Periodic flushing of coils or optional float tank is
recommended.
Step 1 Fill a container with 4 gallons of water, then .
add 1 lb. of deliming powder. Mix thoroughly.
Pour mixture into float tank.
Step 2 Remove wandassemblyfromspray gun and
put spray gun into float tank. Secure the trig-
ger on the spray gun into the open position.
Step 3 Turn engine on, allowing solution to be
pumped through coils back into the float tank.
Thesolutionshouldbeallowedtocirculate2-4
hours or until the color changes.
Step 4 After circulating solution, flush the entire
system with fresh water. Clean out float tank
andthenreinstallwandassemblytospraygun.
Removal of Soot from Heating Coil:
In the heating process, fuel residue in the form of soot
deposits may develop between the heating coil pipe,
and block air flow which will affect burner combustion.
When soot has been detected on visual observation,
the soot on the coil must be washed off after following
the coil removal steps (See Coil Removal section).
Fuel:
Use clean fuel oil that is not contaminated with water
anddebris.Replace fuel filterand draintank every100
hours of operation.
Use No.1 or No 2 Heating Oil (ASTM D306) only.
NEVERusegasolinein yourburnerfueltank.Gasoline
is more combustible than fuel oil and could result in a
serious explosion. NEVER use crankcase or waste oil
in your burner. Fuel unit malfunction could result from
contamination.
Fuel Control System:
This machine utilizes a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combus-
tion chamber.The solenoid, which is normally closed,
is activated by a flow switch when water flows through
it.When the operator releases the trigger on the spray
gun, the flow of water through the flow switch stops,
turning off the electrical current to the fuel solenoid.
The solenoid then closes, shutting off the supply of
fuel to the combustion chamber. Controlling the flow
of fuel in this way gives an instantaneous burn-or-no-
burn situation, thereby eliminating high and low water
temperatures and the combustion smoke normally
associated with machines incorporating a spray gun.
Periodic inspection, to insure that the fuel solenoid
valve functions properly, is recommended. This can
be done by operating the machine and checking to
see that the burner is not firing when the spray gun is
in the OFF position.
Fuel Pressure Adjustment:
To control water temperature, adjust fuel pressure
by turning the regulating pressure adjusting screw
clockwise to increase, counterclockwise to decrease.
NOTE: Whenchangingfuelpump, a bypassplugmust
be installed in return port or fuel pump will not prime.
Burner Nozzle:
Keep the tip free of surface deposits by wiping it with
a clean, solvent saturated cloth, being careful not to
plug or enlarge the nozzle. For maximum efficiency,
replace the nozzle each season.

it may be necessary to adjust the air band setting.Ad-
just air band for a #1 or #2 smoke spot on the Bacha-
rach scale.If a smoky or eye-burning exhaust is being
emitted from the stack, two things should be checked.
First,checkthefuel to becertainthat keroseneor No.1
home heating fuel is being used. Next, check the air
adjustment on the burner.An oily, smoky fire indicates
a lack of air and the air band should be moved to allow
the air to flow through the burner. Sharp eye-burning
fumes indicate too much air flowing through the com-
bustion chamber. The air band should be readjusted
to allow less air to flow through the burner.
To adjust, start the machine and turn burner ON.
Loosen two locking screws found in the air shutter
openings (see illustration) and close air shutter until
black smoke appears from burner exhaust vent. Note
air band position. Next, slowly open the air shutter
until white smoke just starts to appear.Turn air shutter
halfway back to the black smoke position previously
noted.Tighten locking screws.
If the desired position cannot be obtained using only
theair shutter, lockthe air shutter in as closea position
as can be obtained, then repeat the above procedure
on the air band setting.
