INSTALLATION
PRESSURE WASHER
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
Remove bolts from pallet to foot bracket. Install rubber
feet provided as shown in exploded view.
Location:
The location should protect the machine from damaging environmental conditions, such as; wind, rain, and
freezing.
1. This machine should be run on a level surface
where it is not readily influenced by outside sources such as strong winds, freezing temperatures,
rain, etc. It should be located to allow accessibility
for refilling of fuel, adjustments and maintenance.
Normal precautions should be taken by the operator of the machine to prevent moisture from
reaching the electrical controls.
2. It is recommended that a partition be made between the wash area and the machine to prevent
water spray from coming in contact with the
machine. Excess moisture reaching any electric
components or electrical controls will reduce machine life and may cause electrical shorts.
3. During installation of the machine, beware of
poorly ventilated locations or areas where exhaust
fans may cause an insufficient supply of oxygen.
Sufficient combustion can only be obtained when
there is a sufficient supply of oxygen available for
the amount of fuel being burned. If it is necessary
to install a machine in a poorly ventilated area, outside fresh air may have to be piped to the burner
and a fan installed to bring air into the machine.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor
and walls. (Two feet away from walls should be adequate.)
Water Source:
The water source for the pressure washer should be
supplied by a minimum 5/8” I.D. garden hose with a
city water pressure of not less than 30 PSI. If the water
supply is inadequate, or if the garden hose is kinked,
the attached pressure washer will run very rough and
the burner will not fire.
Connection:
See Component Identification.
Venting:
Adding exhaust vent pipe to your oil fired burner is
not recommended because restricted air flow causes
carbon build-up, which affects the operation, and increases maintenance on the coil. If a stack must be
used, refrain from using 90° bends. If the pipe can not
go straight up then use only 45° bends and go to the
next size pipe. The overall pipe length must not exceed
6 feet in length. The burner air adjustment must be
performed after vent pipe is installed. Use a smoke
tester for proper air setting.
OPERATOR’S MANUAL
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter.

WARNING
DETERGENTS AND GENERAL OPERATING TECHNIQUES
PRESSURE WASHER
WARNING: Some detergents
may be harmful if inhaled or
ingested, causing severe nausea, 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 damage the pump. Prepare detergent
solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the
filter end of detergent suction tube
into the detergent container.
STEP 2: With the motor running,
pull trigger to operate machine.
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 injection system after each use by placing the suction
tube into a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
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
to be drying, simply wet down surface with fresh 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
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
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 and other corrosive chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Trisodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.
OPERATOR’S MANUAL
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
desired high pressure nozzle. NOTE: You can also stop
detergent from flowing by simply removing detergent
siphon tube from bottle.

switch off and continue
spraying water, allowing
the water to cool. After
water has cooled to less
than 100°F, turn the attached pressure washer
off.
CAUTION: Always store your pressure washer in a
location where the temperature will not fall below
32°F (0°C). The pump in this machine is susceptible
to permanent damage if frozen. FREEZE DAMAGE
IS NOT COVERED BY WARRANTY.
1. Stop the pressure washer, squeeze spray gun
trigger to release pressure.
2. Detach water supply hose and high pressure
hose.
3. Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately.
4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become
kinked.
6. Store the machine and accessories in a room
which does not reach freezing temperatures.
CAUTION: Failure to follow the above directions will
result in damage to your pressure washer.
When the pressure washer is not being operated or is
being stored for more than one month, follow these
instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve
and carburetor.
3. Pour about one teaspoon of engine oil through
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 indicates
the piston is on its compression stroke and leave
it in that position. This closes both the intake and
10
exhaust valves to prevent rusting of cylinder.
STEP 3: Turn garden hose
water off. Open the spray
gun to relieve remaining
pressure.
STORAGE
4. Cover the pressure washer and store in a clean, dry
place that is well ventilated away from open flame
or sparks. NOTE: The use of a fuel additive, such
as STA-BIL®, or an equivalent, will minimize the
formulation of fuel deposits during storage. Such
additives may be added to the gasoline in the 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,
lose power and may stall. This temporary condition can
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 maintenance of the engine.

PREVENTATIVE MAINTENANCE
PRESSURE WASHER
1. Use clean fuel - kerosene, No. 1 home heating
fuel or diesel. Clean or replace fuel filter every
100 hours of operation. Avoid water contaminated
fuel as it will seize up the fuel pump. De-soot coils
monthly. Use an additive if diesel is being used.
2. Check to see that the attached pressure washer
water pump is properly lubricated.
3. Follow winterizing instructions to prevent freeze
damage to pump and coils.
4. Always neutralize and flush detergent from system
after use.
5. If water is known to be high in mineral content, use
a water softener on your water system, or de-scale
as needed.
6. Do not allow acidic, caustic or abrasive fluids to
be pumped through system.
7. Always use high grade quality cleaning products.
8. Never run attached pressure washer pump dry for
extended periods of time.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Maintenance and Service).
10. Never allow water to be sprayed on or near the
motor or burner assembly or any electrical component.
11. Delime coils as per instructions.
It is advisable, periodically, to visually inspect the
burner. Check air inlet to make sure it is not clogged
or blocked. Wipe off any oil spills and keep equipment
clean and dry.
The areas around the machine should be kept clean
and free of combustible materials, gasoline and other
flammable vapors and liquids.
The flow of ventilating air to the burner must not be
blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Winterizing Procedure:
Damage due to freezing is not covered by warranty.
Adhere to the following cold weather procedures whenever the washer must be stored or operated outdoors
under freezing conditions.
During winter months, when temperatures drop below 32°F, protecting your machine against freezing
is necessary. Store the machine in a heated room. If
this is not possible use compressed air on the short
hose end. By injecting compressed air, all water will
be blown out of the system. Run anti-freeze through
the system.
97-6133 • Rev. 5/07
Rupture Disk:
For safety, each machine is equipped with a rupture
disk. In the event the pressure of the water should exceed 8000 PSI, the rupture disk will release pressure
and water on to the ground.
When the disk ruptures, it will need to be replaced.
NOTE: Turn burner switch off. Then open spray
gun to cool heating coil or rupture disk will burst
over time.
Adjustable Thermostat:
The adjustable thermostat can be set between 100°F
to 225°F (37.8° to 108°C). The temperature is depen-
dent on water flow and ambient water temperature.
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the coil pipes. This growth is increased
by the extreme heat build up in the coil. The best
prevention for liming conditions is to use high quality
cleaning detergents. In areas where alkaline water is
an extreme problem, periodic use of Deliming Powder will remove lime and other deposits before coil
becomes plugged.
Deliming Coils With A Pressure Washer:
Periodic flushing of coils or optional float tank is recommended.
Step 1 Fill a 5 gallon bucket with 4 gallons of water,
then add 1 lb. of deliming powder. Mix thoroughly.
Step 2 Remove the high pressure nozzle from the
pressure wand and put the wand into the
bucket. Secure the trigger on the spray gun
in the open position.
Step 3 Attach a short section (3-5 ft.) of garden hose
to the attached pressure washer to siphon
solution from the elevated bucket. Start up
pressure washer, allowing solution to be
pumped through pressure washer and into
coils and back into the bucket. Solution should
be allowed to circulate 2-4 hours.
Step 4 After circulating solution flush entire system
with fresh water.
Removal of Soot In Heating Coil:
In the heating process fuel residue, in the form of soot
deposits, may develop between the heating coil pipes
and block air flow which affects burner combustion.
When soot has been detected on visual observation,
the soot on the coil must be cleaned off.

MAINTENANCE AND SERVICE
Fuel:
Use clean fuel oil that is not contaminated with water
and debris. Replace fuel filter and drain tank every
100 hours of operation. Use Kerosene No. 1 or No.
2 Heating Fuel (ASTM D306) or diesel only. NEVER
use gasoline in your burner tank. Gasoline is more
combustible than fuel oil and could result in a serious
explosion. NEVER use crankcase or waste oil in your
PRESSURE WASHER
burner. Fuel machine malfunction could result from
contamination.
Ignition Circuit:
Periodically inspect wires, spring contact and electrodes for condition, security and proper spacing.

Electrodes Check : Periodically check wiring connections.
If necessary to adjust electrodes, use diagram.
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. Select nozzle size
based on the pressure washer you will be using:
Nozzle Pressure Washer GPM
1.50 2 - 3
1.75 3 - 4
2.00 - 2.25 4 - 5
All nozzles should be 45° W
Fuel Control System:
The machine utilizes a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combustion chamber. This solenoid, which is normally
closed, is activated by a flow switch when water is
flowing through it. When an operator releases the
trigger on the spray gun, the flow of water through the
flow switch stops, turning off the current to the fuel
solenoid. The solenoid then closes, shutting off the
14
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 combustion smoke normally
associated with machines incorporating a spray gun.
Periodic inspection is recommended to insure that
the fuel solenoid valve functions properly. This can be
done by operating the machine and checking to see
that when the trigger on the spray gun is in the off
position, the burner is not firing.
Fuel Pressure Adjustment:
To adjust fuel pressure, turn the adjusting screw with
a 5/32” allen wrench (located on the fuel pump) clockwise to increase, counterclockwise to decrease. Do
not exceed 200 PSI.
FIELD REPAIR
INSTRUCTIONS
Fuel Pump:
1. Remove the screws 10/32” Allen Head from the
machine hood.
2. Remove louvered hood.
3. With a 9/16” wrench, loosen (DO NOT REMOVE)
the two 3/8” x 3/4” HH NC serrated flange bolts
that secure the front panel.
4. With a 2.5 mm hex head wrench (Allen Wrench),
loosen the three set screws that hold the fuel pump
