WARNING
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.
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.
OPERATOR’S MANUAL
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.

THERMAL PUMP
PROTECTION
• 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 products 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.

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 through use of dipstick found on top of
pump or red dot visible through oil gauge window. Oil
should be maintained at that level.

Fuel Control System:
Ignition Circuit:
Periodically inspect wires, spring contact and electrodes for condition, security and proper spacing.
Transformer test: (CAUTION 10,000 VOLTS) use
defect free 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.
(See illustration.)
These machines utilize a fuel solenoid valve located on
the fuel pump to control the flow of fuel to the combustion chamber. This solenoid valve, 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 supply of fuel to
the combustion chamber. Controlling the flow of fuel in
this way allows for 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.
16
LANDA SEHW • 8.913-932.0 • Rev. 02/12a
CAUTION: 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.

AIR SHUTTER
LOCKING SCREW
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.
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.
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 preventative for liming conditions is to use high quality
cleaning detergents. In areas where alkaline water is an
extreme problem, periodic use of Landa Deliming Powder (Landa Part #9-028008) will remove lime and other
deposits before coil becomes plugged. (See Deliming
Instructions for use of Landa Deliming Powder.)

LOCKING SCREW
The oil burner on this machine is preset for operation at altitudes below 1000 feet. If operated at higher
altitudes, it may be necessary to adjust the air band
setting. Adjust air band for a #1 or #2 smoke spot on
the Bacharach scale. A one-time initial correction for
your location will pay off in economy, performance,
and extended 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 kerosene or No. 1 home heating fuel is being
used. Next, check the air adjustment on the burner. An
oily, 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 fumes indicate too much air
flowing through the combustion chamber. The air band
should be readjusted to allow less air to flow through
the burner.
To adjust: start machine and turn burner ON. Loosen
two locking screws found in the air shutter openings
(refer to illustration on page 8) 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.
OPERATOR’S MANUAL
To adjust fuel pressure, turn the pressure adjusting
screw clockwise to increase, counterclockwise to decrease. Do not exceed 200 psi. NOTE: When changing
fuel pump, a by-pass plug must be installed in return
line port or fuel pump will not prime. (See illustration)
as can be obtained, then repeat the above procedure
on the air band setting.

MAINTENANCE & SERVICE
Deliming Coils:
Periodic flushing of coils is recommended.
Step 1
Step 2
Step 3
Step 4
Fill the float tank with 4 gallons of water, then add 1 lb. of deliming powder.
Mix thoroughly.
Remove nozzle from the wand assembly and put the wand and spray gun into float tank. Attach a nylon stocking to the end of the wand to collect debris.
Turn pump switch on, allowing solution to be .
pumped through coils and back into the float .
tank. Solution should be allowed to circulate .
2 - 4 hours.
After circulating solution, clean and drain float tank and flush entire system with fresh water. Replace nozzle in wand.
Spray Nozzles:
Each machine is equipped with one spray nozzle. Different spray nozzles are calibrated for each machine
depending on the flow and pressure of that particular
model. Spray nozzles vary in bore size and angle of
spray. Popular spray angles are 0°, 15°, 25°, 40°. When
ordering, please specify size and angle of nozzle.
Nozzle size for each machine is located on the serial
plate.
If the desired position cannot be obtained using only
the air shutter, lock the air shutter in as close a position

MAINTENANCE & SERVICE
Unloader Valve:
Coil Removal:
The unloader valve traps pressure in the line when the
spray gun is closed. Machines with unloader valves
are preset and tested at the factory before shipping.
Tampering with the factory setting may cause personal injury and/or property damage, and will void the
manufacturer's warranty. Occasional adjustment of the
unloader may be necessary to maintain correct pressure. Consult your local Landa Dealer for the correct
procedure in adjusting the unloader valve.
Removal of the coil, because of freeze breakage or to
clean soot from it, can be done quickly and easily.
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. Siphoning a small amount of antifreeze into the
system is recommended. This is done by pouring a
50/50 mix of antifreeze and water into the float tank and
then siphoning 100% antifreeze through the detergent
line with the pump on. If compressed air is available,
an air fitting can be screwed into float tank strainer fitting and, by injecting compressed air, all water will be
blown out of the system.
Low Pressure Diagnosis:
Refer to Troubleshooting Chart for low pressure. If, by
referring to the chart, the trouble is found to be either
the unloader or pump, your next step is to determine
which is the problem. This can be done by eliminating
the unloader from the system and attaching the discharge hose directly to the pump. If high pressure is
present, then the unloader needs repairing.
1.Disconnect hose from pump to inlet side of the coil.
2.Carefully disconnect thermostat sensor, making
sure you do not crimp capillary tube.
3.Remove all the fittings from the inlet and discharge
side of coil.
4.Remove the burner assembly from the combustion
chamber.
5.Remove the 3-3/8" bolts from each side of coil and
tank assembly (these bolts are used to fasten tank
and handles to chassis).
6.Remove the two bolts which are underneath the
bottom wrap (to keep the coil from moving).
7.R emove tank top wrap exposing insulation
and coil.
8. Bend back insulation tabs.
9.C arefully fold back the insulation and remove
insulation retainer plates and coil.
10.Replace or repair any insulation found to be torn
or broken.
11.To reinstall new or cleaned coil, reverse steps 9
through 1.
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.
CAUTION: The thermostat uses a capillary tube. Do
not bend or strike with any object.
CAUTION: When using this procedure to test components, keep spray gun open at all times.
Removal of Soot and 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 which follow.

3.
4.
5.
Remove lock nut (Item 19).
Remove adjustment knob (Item 18).
Loosen the two (2) nuts (Item 15), move them upward on stem (Item 8) until you see 4 or more threads below the nut.
Re-attach adjusting knob (Item 18).
Start machine. Open the trigger of the spray gun. Increase pressure by turning adjustment knob (Item 18) clockwise
until pressure is at the desired operating pressure.
6. Remove the adjustment knob (Item 18), tighten the lower nut (Item 15) tightly against the upper nut (Item 15). Reattach adjustment knob (Item 18) and screw down until contact is made with the nuts (Items 15). Screw down lock nut
(Item 19) onto the stem (Item 8) until the threads cut into the nylon insert of the lock nut (Item 19).
*If adjustment knob (Item 18) DOES NOT make contact with upper nut (Items 15), remove adjusting knob (Item 18), re-adjust
(raise) nuts (Items 15) on stem (Item 8) and re-attach adjustment knob (Item 18), then repeat step #6.
**If adjustment knob (Item 18) DOES make contact with upper nut; release the trigger of the spray gun and watch the pressure gauge for the pressure increase (“spike”). This “spike” SHOULD NOT exceed 500 psi above the operating pressure. If
“spike” pressure exceeds the 500 psi limit, remove the adjusting knob (Item 18) and re-adjust (lower) the nuts (Items 15) on
the stem (Item 8). Re-attach the adjusting knob (Item 18), then repeat step #6.

SEVEN YEAR PARTS AND ONE YEAR LABOR WARRANTY:

manufacturers’ local authorized service centers. LANDA is not authorized and has no responsibility to provide warranty
service for such components.

1. Normal wear items, such as nozzles, spray guns, discharge hoses, wands, quick couplers, seals, filters, gaskets, O-rings, packings, pistons, pump valve assemblies, strainers, belts, brushes, rupture disks, fuses, pump

5. Normal maintenance service, including adjustments, fuel system cleaning, and clearing of obstructions.

WHAT YOU MUST DO TO OBTAIN WARRANTY SERVICE
While not required for warranty service, we request that you register your LANDA pressure washer by returning the completed registration card. In order to obtain warranty service on items warranted by LANDA, you must return the product
to your Authorized LANDA Dealer, freight prepaid, with proof of purchase, within the applicable warranty period. If the
product is permanently installed, you must notify your Authorized LANDA Dealer of the defect. Your Authorized LANDA
Dealer will file a claim with Landa, who must subsequently verify the defect. In most cases, the part must be returned
to LANDA freight prepaid with the claim. For warranty service on components warranted by other manufacturer’s, your
Authorized LANDA Dealer can help you obtain warranty service through these manufacturers’ local authorized service
centers.
LIMITATION OF LIABILITY
LANDA’S liability for special, incidental, or consequential damages is expressly disclaimed. In no event shall LANDA’S
liability exceed the purchase price of the product in question. LANDA makes every effort to ensure that all illustrations
and specifications are correct, however, these do not imply a warranty that the product is merchantable or fit for a
particular purpose, or that the product will actually conform to the illustrations and specifications. Our obligation under
this warranty is expressly limited at our option to the replacement or repair at a service facility or factory designated by
us, of such part or parts as inspection shall disclose to have been defective. THE WARRANTY CONTAINED HEREIN

make any representation or promise on behalf of LANDA, or to modify the terms, conditions, or limitations in any way.
It is the buyer’s responsibility to ensure that the installation and use of LANDA products conforms to local codes. While
LANDA attempts to assure that its products meet national codes, it cannot be responsible for how the customer chooses
to use or install the product. Some states do not allow limitations on how long an implied warranty lasts or the exclusion
or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
