IMPORTANT SAFETY INFORMATION
INSTALLATION
Place machine in a convenient location providing ample
support, draining and room for maintenance.
This machine is intended for indoor use. Machine
must be stored indoors when not in use.
PRESSURE WASHER
Follow the maintenance instructions
specified in the manual.
Location:
The location should protect the machine from damag-
ing 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 temperature, 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 pre-
vent 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.

OPERATING INSTRUCTIONS
PRESSURE WASHER
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 buildup, which affects the operation, and increases maintenance on the coil. If a stack must be
used, refrain form 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.
5. Insert quick coupler onto discharge nipple and
secure by pushing quick coupler collar forward.
6. Securely attach the desired high pressure nozzle
into wand coupler as described in steps 4 and 5.
7. Connect the power cord into the proper electrical
outlet, then push in the GFCI reset button (Refer
to serial plate for information.)
8. Grip spray gun handle securely and pull trigger.
Then turn variable pressure control handle counterclockwise.
9. Turn switch to pump position. When a steady
stream of water flows from the spray gun and wand,
the machine is ready for cold water cleaning by turn-
ing the variable pressure control handle clockwise
to raise the pressure.

PREVENTATIVE MAINTENANCE AND SERVICE
PREVENTATIVE MAINTENANCE
1. Use clean fuel - kerosene, No. 1 home hearing
fuel or diesel fuel. Clean or replace fuel lter 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 Procedures to prevent freeze
damage to pump coils.
4. Always neutralize and ush detergent from system
after use.
5. If water is known to be high in mineral content, use
a water softener in your water system or de-scale
as needed.
6. Do not allow acidic, caustic or abrasive uids to be
pumped through system.
7. Always use high grade quality cleaning products.
8. Never run pump dry for extended periods of time.
9. If machine is operated with smoking or eye burning
exhaust, coils will soot up, not letting water reach
maximum operating temperature. (See section on
Air Adjustments.)
10. Never allow water to be sprayed on or near engine
or burner assembly or any electrical component.
11. Periodically delime coils 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 this equipment clean and dry.
The areas around the pressure washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
MAINTENANCE AND SERVICE
Unloader Valves:
Unloader valves are preset and tested at the factory
before shipping. Occasional adjustment of the unloader
may be necessary to maintain correct pressure. Call
your local dealer for assistance.
Winterizing Procedure:
Damage due to freezing is not covered by warranty.
Adhere to the following cold weather procedures
whenever 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 machine in
a heated room. If this is not possible then mix a 50/50
9.800-191.0 • Rev. 04/09
solution of anti-freeze/water into a 5 gallon bucket.
Place a short section of garden hose into bucket and
connect it to machine. Elevate bucket and turn pump on
to siphon anti-freeze through 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 system.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a high limit
control switch. In the event that 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 30W non-detergent oil. Change oil after
the first 50 hours of use. Thereafter, change the oil
every three months or at 500 hour intervals. Oil level
should be checked by using the dipstick found on top
of the pump or 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 (part #9.804-
059.0) will remove lime and other deposits before coil
becomes plugged. (See Deliming Instructions for use
of Deliming Powder.)
Deliming Coils:
Periodic flushing of coils is recommended.
1. Fill a container or optional oat tank with 4 gallons
of water, then add 1 lb. of deliming powder. Mix
thoroughly.
2. Remove wand assembly from spray gun and put
spray gun into container. Secure the trigger on the
spray gun into the open position.
3. Attach a short section (3-5 ft.) of garden hose to
machine to siphon solution from an elevated container. Turn pump switch on, allowing solution to
be pumped through coils back into the container.
Solution should be allowed to circulate 2-4 hours.
4. After circulating solution ush entire system with
fresh water. Reinstall wand assembly to spray
gun.
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,
