to dry on surface.
IMPORTANT:Youmustflushthe detergentfromyour
machineafter each useby 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
minuteswithoutpressingthetriggeronthespraygun,
circulatingwaterinthe pump can reach high tempera-
tures.When the water reaches this temperature, the
pump protector engages and cools the pump by dis-
chargingthewarmwaterontothe ground.Thisthermal
devicepreventsinternal 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
yourworkarea to sections approximately 6feetsquare
and always apply detergent from bottom to top). Allow
detergenttoremain on surface 1-3 minutes. Do not al-
low 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
fromcleaningsurface.Use overlapping strokesasyou
clean and rinse any surface.For best surface cleaning
action spray at a slight angle.
Recommendations:
• Beforecleaninganysurface,aninconspicuousarea
should be cleaned to test spray pattern and dis-
tance for maximum cleaning results.
• Ifpaintedsurfaces are peeling or chipping, use ex-
tremecautionas pressure washermayremove the
loose paint from the surface.
• Keepthespraynozzle asafedistance from the sur-
face you plan to clean.High pressure wash a small
area,thencheckthesurfacefordamage.Ifnodam-
age is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquidscontainingsolvents(i.e.,paint thinner,gaso-
line, oils)

Clean or replace fuel filter every 100 hours of op-
eration. Avoid water contaminated fuel as it will
damage the fuel pump.
9. If machine is operated with smoky or eye burning
exhaust, coils will soot up, not letting water reach
maximumoperatingtemperature.
10. Never allow water to be sprayed on or near engine
or burner assembly or any electrical component.
11. Periodically delime coils as per instructions.
12. Check to see that engine is properly lubricated.
Itisadvisable,periodically,tovisuallyinspecttheburner.
Check air inlet to make sure it is not clogged or blocked.
Wipeoff anyoilspills and keepequipment cleanand dry.
Theflowofcombustionandventilatingair totheburner
must not be blocked or obstructed in any manner.
The area around the pressure washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
MAINTENANCE AND SERVICE
Unloader Valves:
Unloader valves are preset and tested at the factory
beforeshipping.Occasionaladjustmentof theunloader
may be necessary to maintain correct pressure.
Winterizing Procedure:
Damage due to freezing is not covered by warranty.
Adhereto thefollowing cold weatherprocedures when-
ever the washer must be stored or operated outdoors
under freezing conditions.
During wintermonths, when temperaturesdrop 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
and water in the float tank. Turn the engine on to si-
phon the anti-freeze mixture through the machine. If
compressed 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 trig-
ger on the spray gun is opened.
High Limit HotWaterThermostat:
For safety, each machineis equippedwith atempera-
turesensitivehighlimitcontrolswitch.In theevent that
the water should exceed its operating temperature,
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:
Before running the pump check the pump crankcase
for 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 the dipstick.Use only SAE 30 non-de-
tergentoil.Changetheinitialoilafterthefirst50 hours
andthen change theoilevery500hours or every three
months.
Whendrainingoil,clean inside ofcrankcasetoremove
all impurities. CAUTION: When operating in damp
places or with high temperature fluctuations oil must
be changed immediately.
Cleaning of Coils:
Inalkalinewaterareas,limedepositscanaccumulate
rapidlyinsidethe heating coil.Thisgrowthis increased
by the extreme heat build up in the coil.The best pre-
ventative for liming conditions is to use high quality
cleaning detergents.In areas where alkaline water is
an extreme problem, periodic use of Coil Conditioner
will remove lime and other deposits before coil be-
comes plugged.(See Deliming instructions for use of
CoilConditioner.)
Deliming Coils:
Periodic flushing of coils or optional float tank is rec-
ommended.
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 wand assembly from spray 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 throughcoilsbackinto the float tank.
The solution should be allowed to circulate
2- 4 hours or until the color changes.
Step 4 After circulating solution, flush the entire sys-
tem with fresh water.Clean out float tank and
then reinstall wand assembly to spray gun.

PRESSURE WASHER OPERATOR’S MANUAL
MAINTENANCE
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).
Rupture Disk:
If pressure from pump or thermal expansion should
exceed safe limits, the rupture disk will burst allowing
highpressure tobedischarged throughhoseto ground.
When disk ruptures it will need to be replaced.
Fuel:
Use clean fuel oil that is not contaminated with water
anddebris.Replacefuelfilteranddraintank every100
hours of operation.
Use No.1 or No 2 Heating Oil (ASTM D306) only.
NEVER use gasoline in your burner fuel tank. Gaso-
line is more combustible than fuel oil and could result
inaserious explosion.NEVERuse crankcaseorwaste
oil in your burner. Fuel unit malfunction could result
fromcontamination.
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.
Thesolenoidthen closes,shuttingoffthesupply of fuel
tothecombustionchamber.Controllingthe flowoffuel
inthis waygivesan instantaneousburn-or-no-burnsitu-
ation,therebyeliminating high and lowwatertempera-
tures and the combustion smoke normally associated
with machines incorporating a spray gun. Periodic in-
spection, to insure that the fuel solenoid valve func-
tions 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 clock-
wisetoincrease,counterclockwiseto decrease.Donot
exceed 200 psi. NOTE: When changing fuel pump, a
bypassplug mustbeinstalledinreturnportor fuelpump
will not prime.
Burner Nozzle:
Keepthetipfreeofsurfacedepositsbywiping it with a
clean,solventsaturatedcloth,being careful nottoplug
orenlarge thenozzle.Formaximumefficiency, replace
the nozzle each season.
Air Adjustment:
Machines are preset and performance tested at the fac-
tory - elevation100'.A one-time initial correction for your
location will pay off in economy, performance, and ex-
tended service life.If a smoky or eye-burning exhaust is
being emitted from the stack, two things should be
checked. First, check the fuel to be certain that kero-
sene or No. 1 home heating fuel is being used. Next,
check the air adjustment on the burner.
To adjust, start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings (re-
fer to illustration) and close air shutter until black smoke
appears from burner exhaust vent. Note air band posi-
tion. 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.
