Operating Instructions
STEP 1: Check engine oil level. Oil level should be
level to the fill markings on the dipstick. Be sure the
machine is level when checking the oil level. (Refer to
the engine's operating manual included with machine.)
We recommend that the oil be changed after the first 5
hours of use, then once every 100 hours. Note:
Improper oil levels will cause low oil sensor to shut off
engine.
CAUTION: Do not run engine with high or low oil
levels as this will cause engine damage.
ATTENTION : Ne pas faire fonctionner le moteur si
le niveau d'huile est trop haut ou trop bas, car cela
risquerait d'endommager le moteur.
STEP 3: Connect garden hose to the cold water source
and turn water on completely. Never use hot water.
STEP 2: Fill gas tank with unleaded gasoline. Do not
use leaded gasoline.
STEP 4: Before installing pressure nozzle, trigger
spray gun to eliminate trapped pressure. Then run
machine, allowing water to flush through the system
until clear. Engage the safety latch before inserting
high pressure nozzle.

STEP 5: Pull the choke lever out to the "Choke"
position (on a warm engine, leave the choke lever in
the run position). Push the choke lever to the "Closed"
position. To restart a warm engine, leave the choke
lever in the "Open" position.
STEP 7: (Electric Start Models) Turn the engine
switch to "Start" position.
STEP 6: (Non-Electric Start Models) Pull the starter
grip. If the engine fails to start after 2 pulls, squeeze the
trigger gun to release pressure and repeat step. Return
starter gently. After the engine warms up enough to run
smoothly, move choke to run position and throttle to
fast position.
WARNING: Starter cord kickback (rapid retraction)
can result in bodily injury. Kickback will pull hand
and arm toward engine faster than you can let go.
Always relieve spray gun pressure before pulling
starter cord. Pull starter cord slowly until resis-
tance is felt, then pull rapidly
AVERTISSEMENT : Le retour du cordon de
lancement (rétraction rapide) peut causer des
lésions corporelles. La rétraction rapide de la
corde du démarreur (recul) attire la main et le bras
vers le moteur plus vite qu'il n'est possible de
lâcher la corde. Toujours réduire la pression du
pistolet pulvérisateur avant de tirer sur le cordon
de lancement. Tirer lentement sur le cordon de
lancement jusqu'à ce qu'une résistance soit sentie,
puis tirer rapidement.

STEP 8: (Electric Start Models) Turn the key to the
START position, and hold it there until the engine starts.
If the engine fails to start within 5 seconds, release the
key, and wait at least 10 seconds before operating the
starter again.
Using the electric starter for more than 5 seconds
at a time will over heat the starter motor and can
damage it.
When the engine starts, release the key, allowing it to
return to the ON position. If the choke knob has been
pulled to the CLOSED position to start the engine,
gradually push it to the OPEN position as the engine
warms up.
STEP 10: (Pump Steam Option)
a. Operate machine as instructed.
b. Open steam valve counterclockwise, which will
lower pressure.
c. Turn thermostat knob to 250°F.
d. When steam is no longer desired, Turn steam
valve clockwise and thermostat knob to 200°F.
STEP 9: Turn the burner switch “ON”. Turn thermostat
dial to the 210° mark.
WARNING! Never replace nozzle without engaging
the safety latch on the spray gun trigger.
AVERTISSEMENT : Ne jamais remplacer les buses
sans d'abord mettre le dispositif de sécurité sur la

Detergents & General Cleaning
Techniques
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. Read msds
before handling.
AVERTISSEMENT : Certains
détergents peuvent être
dangereux s'ils sont inhalés ou
ingérés, provoquant de fortes nausées, des
évanouissements et l'empoisonnement. Les
éléments dangereux peuvent causer des
dommages à la propriété ou des blessures graves.
Lire la fds avant la manipulation.
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: Open detergent metering valve.
STEP 3: Detergent will 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, 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 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 tempera-
tures. 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.
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 over-
lapping 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.

• Liquides contenant des solvants (c.-à-d. diluant
à peinture, essence, huiles, etc.)
• Produits à base de tripolyphosphate de sodium
• Ammoniac ou produits à base d'acide
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.

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 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 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.
ATTENTION : Avant de redémarrer, faire fondre la
glace se trouvant sur les boyaux, le pistolet pulvéri-
sateur ou la lance de la laveuse à pression.
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 mainte-
nance of the engine.

Maintenance
Preventative Maintenance
1. Check to see that water pump is properly lubri-
cated.
2. Follow winterizing instructions to prevent freeze
damage to pump and coils.
3. Always neutralize and flush detergent from system
after use.
4. If water is known to have high mineral content, use
a water softener in your water system, or de-scale
as needed.
5. Do not allow acidic, caustic or abrasive fluids to be
pumped through system.
6. Always use high grade quality cleaning products.
7. Never run pump dry for extended periods of time.
8. Use clean fuel: kerosene, No. 1 fuel oil, or diesel.
Clean or replace fuel filter every 100 hours of oper-
ation. 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
maximum operating temperature.
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.
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 flow of combustion and ventilating air to the burner
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
before shipping. Occasional adjustment of the unloader
may be necessary to maintain correct pressure.
Adjusting Unloader Valves:
Tampering with the factory setting may cause personal
injury and/or property damage and will void the manu-
facturer's warranty.
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
and water in the float tank. Turn the engine on to siphon
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 trigger
on the spray gun is opened.
High Limit Hot Water Thermostat:
For safety, each machine is equipped with a tempera-
ture sensitive high limit control switch. In the event 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 thermo-
stat 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-detergent
oil. Change the initial oil after the first 50 hours and then
change the oil every 500 hours or every three months.
When draining oil, clean inside of crankcase to remove
all impurities.
CAUTION: When operating in damp places or with high
temperature fluctuations oil must be changed immedi-
ately.
ATTENTION : Lorsque l'appareil est utilisé dans des
endroits humides ou où les températures fluctuent
fortement, l'huile doit être changée immédiatement.
Kärcher SSG Operator’s Manual 9.801-193.0 - BF

Maintenance
Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate
rapidly inside the heating coil. This growth is increased
by the extreme heat build up in the coil. The best
preventative 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
becomes plugged. (See Deliming instructions for use of
Coil Conditioner.)
Deliming Coils:
Periodic flushing of coils or optional float tank is recom-
mended.
1. Fill a container with 4 gallons of water, then add 1
lb. of deliming powder. Mix thoroughly. Pour
mixture into float tank.
2. Remove wand assembly from spray gun and put
spray gun into float tank. Secure the trigger on the
spray gun into the open position.
3. Turn engine on, allowing solution to be pumped
through coils back into the float tank. The solution
should be allowed to circulate 2- 4 hours or until
the color changes.
4. After circulating solution, flush the entire system
with fresh water. Clean out float tank and then
reinstall wand assembly to spray gun.
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
and debris. Replace fuel filter and drain tank every 100
hours of operation.
Use No.1 or No 2 Heating Oil (ASTM D306) only.
NEVER use gasoline in your burner fuel 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.
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 situ-
ation, thereby eliminating high and low water tempera-
tures 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.
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 disk ruptures it will need to be replaced.
The Rupture Disk should be replaced every two years.
Kärcher SSG Operator’s Manual 9.801-193.0 - BF

Maintenance
Fuel Pressure Adjustment:
To adjust fuel pressure, First install a pressure gage
into the port just after the pump fuel exit. Turn the
adjusting screw (located at the regulator port)
clockwise to increase, and counterclockwise to
decrease. Do not exceed 200 psi or lower the pressure
below 130 PSI, when checked at the post-pump
pressure port.
The fuel pressure may need to be adjusted due to
altitude. For every 500 ft altitude above sea level, the
boiling point of water goes down 1 °F. At high altitude
environments, this boiling point change may require the
heat input to be lowered so the water input does not
turn to steam earlier than at the factory settings and
activate the pressure sensors and pressure relief
equipment when the unit is operated and much higher
altitudes from factory settings or local dealer site
settings. Check with your dealer before making local
site fuel pressure adjustments.
Also, as ambient temperature changes seasonally, the
fuel temperature in the feed tank and air temperature
inlet can impact fuel flow. In more extreme tempera-
tures, this local-site adjustment may also require
different fuel nozzles for fuel inlet temperatures that are
at seasonal extremes (higher or lower) in locations
where the temperature changes are beyond moderate
temperatures of between 40°F and 90°F. Colder
temperatures will make for a thicker flow and less fine a
fuel spray while hotter temperatures will make for a
thinner flow a more fine spray with the same nozzle.
Consider alternate nozzle configurations from the
baseline factory-supplied nozzle for operating in such
temperature extremes if performance is not meeting
needs with air band and fuel pressure settings alone.
NOTE: When changing fuel pump, a by-pass plug
must be installed in return line 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.

Oil Burner
Burner Air Adjustment: The oil burner on this machine
is preset for operation at altitudes below 500 feet. If
operated at higher altitudes, it may be necessary to
adjust the air band for a #1 or #2 smoke spot on the
Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need to
be increased; for lower altitude, the .air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the .air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient tempera-
tures, the air band opening may need to be decreased.
Adjust to your operating location’s environment as-
needed for best smoke spot and performance
compliant with local, state, and federal regulations.
Caution: If white smoke appears from burner exhaust
vent during start-up or operation, discontinue use and
readjust air bands.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale.
