INSTALLATION
Place machine in a convenient location providing ample
support, draining and room for maintenance.
This machine is intended for outdoor use. Machine
must be stored indoors when not in use.
Location:
The location should protect the machine from damaging environmental conditions, such as wind, rain, and
PRESSURE WASHER
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 be-
OPERATOR’S MANUAL
tween 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.
Avoid small locations or areas near exhaust fans.
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter.
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:
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon tape
to avoid water leaks. (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*.
*Note: After vent pipe installation test burner using a
smoke tester and adjust air setting to achieve a #3 or
below results.

STEP 2: 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 4: With the engine 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.
THERMAL PUMP
PROTECTION
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal device prevents internal damage to the pump.
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)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These 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
desired high pressure nozzle. NOTE: You can also
stop detergent from flowing by simply removing detergent siphon tube from bottle.
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 temperatures. When the water reaches this temperature, the

Unloader valves trap pressure in the line when a shutoff spray gun is closed. Machines with unloader valves
are preset and tested at the factory before shipping.
Occasional adjustment of the unloader may be necessary to maintain correct pressure.
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 then mix a 50/50 solution of anti-freeze/
water or windshield washer fluid with water in a 5 gallon bucket. Place a short section of garden hose into
the bucket and connect it to the machine. Elevate the
bucket and turn the pump on to siphon the anti-freeze
through the machine. If compressed air is available, an
air fitting can be screwed into the inlet connector and
by injecting compressed air, all water will be blown out
of the system.
If you have an optional float tank, pour the antifreeze
into this tank and run machine until antifreeze exits discharge nipple.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event the temperature of the water should exceed its operating temperature, the high
limit control will turn the burner off until the water cools.
Pumps:
Use only SAE 30 weight non-detergent oil. Change oil
after first 50 hours of use. Thereafter, change oil every
three months or at 500 hour intervals. Oil level should
be checked by using the dipstick found on the top of
the pump or by the red dot visible through the oil gauge
window. Oil should be maintained at that level.
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 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
into 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

MAINTENANCE
PRESSURE WASHER
through pressure washer and into HPB 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 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 coil has
been removed using the following steps:
1. Remove the tank head assembly by unscrewing
the three tek screws and lifting the tank head off.
2. Remove the two pipe nipples and associated fittings.
3. Lift the coil out of the outer wrap.
CAUTION: The coil weighs about 80 lbs. Use proper
lifting techniques.
4. Clean, repair and replace the coil by reversing the
above steps.
Coil Reinstallation
Reinstall by reversing the above steps 4 through 1.
Rupture Disk
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst, allowing
high pressure to be discharged through hose to ground.
When the disk ruptures, it will need to be replaced.
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 gaso-
line 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 burner. Fuel
unit malfunction could result from contamination.
Ignition Circuit:
Periodically inspect wires, spring contact and electrodes
for condition, security and proper spacing. For trans-
former test (CAUTION 10,000 VOLTS) use defect free
97-6068, 97-6131 • REV. 3/06
insulated screwdriver and keep fingers off blade! Lay
blade across one contact: OK if arc will span 1/2" between end of blade and other contact.

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.
Fuel Control System:
This machine utilizes a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combustion chamber. This solenoid is activated by a pressure
switch located on the unloader valve. When an operator
releases the trigger on the spray gun, the pressure drops,
allowing the pressure switch to activate 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 combustion smoke normally associated
with machines incorporating a spray gun. Periodic inspection is recommended to insure that the fuel solenoid valve
OPERATOR’S MANUAL

MAINTENANCE
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
standard screwdriver (located on the fuel pump) clockwise to increase, counterclockwise to decrease. Do not

exceed 200 PSI.
Air Adjustment
Machines are preset and performance tested at the
factory — elevation 100' above sea level. A one time
correction for your location will pay off in economy, performance and extended service life. If a smoky or eyeburning exhaust is being emitted from the stack, two
things should be checked.
First, check the fuel to be certain that kerosene or No.
OPERATOR’S MANUAL
1 home heating fuel is being used.
Next, check the air adjustment on the burner. An oily,
black, 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 white fumes indicate too much air
flowing through the combustion chamber. The air band
should be moved to allow less air to flow through the
burner.
To adjust: start machine and turn burner ON. Loosen
the two locking screws found in the air shutter openings
(refer to illustrations) 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 the
air shutter, lock the air shutter in as close a position as
can be obtained, then repeat the above procedure on
the air band setting.
