tions carefully before using.
1. Read the owner’s manual
thoroughly. Failure to follow
instructions could cause a
malfunction of the machine
and result in death, serious
bodily injury and/or property
damage.
2.Know how to stop the machine and bleed pressures quickly. Be thoroughly familiar with the
controls.
3. Stay alert - watch what you are doing.
4.All installations must comply with local codes.

operating.
DO NOT USE WITH
FLAMMABLE LIQUIDS. 6.On starting, make sure that
the engine is as horizontal
as possible and observe the following steps in
running this pressure washer:
(a) become familiar with how to stop the engine;
(b) never start the engine in a closed space or
where there is insufficient ventilation. Combustion creates carbon monoxide, an odorless and highly poisonous gas. Lengthy stays
in places where the engine freely exhausts
this gas can lead to unconsciousness and
death;
(c) do not operate machine in places containing flammable materials, in explosive atmospheres, or where there is dust that can
easily catch fire unless specific, adequate and
clearly indicated precautions have been taken
and have been certified for the machine;
(d) to prevent fire hazards, always keep the machine at least one meter from buildings or from
other machinery;
(e) to reduce the risk of injury, close supervision
is necessary when a product is used near
children. Do not allow children to operate the
pressure washer. This machine must be attended during operation.
(f) fuel is flammable. The tank must only be filled
when the engine is off. Thoroughly dry any
spilled fuel and move the fuel container and
any rags soaked in fuel or oil. Make sure that
the ground or floor on which the machine is
standing has not soaked up any fuel or oil;
OPERATOR’S MANUAL

OPERATOR’S MANUAL
(g) fully tighten the tank cap each time after refueling. Do not fill the tank to the top but leave an
adequate space for the fuel to expand;
(h) fuel vapor is highly toxic. Only refuel outdoors
or in a well ventilated place;
(i) do not smoke or use open flames when refueling;
(j) the engine must be started in compliance
with the specific instructions in the operation
manual of the engine and/or machine itself.
Do not use auxiliary starting aids that were
not installed on the original machine (e.g.
Startpilot);
(k) before starting, remove any tools that were
used to service the engine and/or machine.
Make sure that all safety guards are in
place;
(l) during operation, the surface of the engine
can be dangerously hot. Avoid touching the
exhaust system in particular;
(m)before proceeding with any operation on the
engine, stop the engine and allow to cool.
Never carry out any operation while the engine
is running;
(n) the oil must be drained while the engine is hot
(176°F). Particular care is required to prevent
burns. Do not allow the oil to come into contact
with the skin;
(o) make sure the drained oil, oil filter and the oil
it contains are disposed of in the correct way
in order to safeguard the environment;
(p) pay attention to the temperature of the oil filter
when the filter itself is replaced;
(q) during operations that involve access to moving parts of this machine and/or removal of
rotating guards, disconnect and insulate the
positive wire of the battery to prevent accidental short-circuits and to stop the starter motor
from being energized;
(r) only check belt tension when engine is off;
(s) only use the eyebolts installed by Lombardini
to move the engine. These lifting points are
not suitable for the entire machine;

STEP 2: 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 after
each use by placing the suction tube into a bucket
of clean water, open detergent valves then run the
pressure washer for 1-2 minutes.
THERMAL PUMP
PROTECTION
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 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.
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.
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.
PRESSURE WASHER
DETERGENTS AND GENERAL OPERATING TECHNIQUES
RINSING
It will take a few seconds for the detergent to clear. Apply safety latch to spray gun and close detergent valve.
Select and install the desired high pressure nozzle.
If you run 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 pump protector
engages and cools the pump by discharging the warm
water onto the ground. This thermal device prevents
internal damage to the pump.

PRESSURE WASHER
OPERATOR’S MANUAL
MAINTENANCE & SERVICE
PREVENTATIVE
MAINTENANCE
1.Check to see that water pump is properly lubricated.
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 be high in mineral content,
use a water softener on 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
operation. 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 the
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.
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 temperature 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 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:
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 the red dot visible through the oil gauge
window. Oil should be maintained at that level.
Cleaning of Coils:
The area around the Landa washer should be kept
clean and free of combustible materials, gasoline and
other flammable vapors and liquids.
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 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.)
MAINTENANCE AND SERVICE
Deliming Coils:
The flow of combustion and ventilating air to the burner
must not be blocked or obstructed in any manner.
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.
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.
Periodic flushing of coils or optional float tank is recommended.
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 trigger
on the spray gun into the open position.
Step 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.
16
Landa PDHW • 8.913-938.0 • Rev. 2/13
Step 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 and Heating Coil:
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:
Diesel fuel must be clean, fresh, meet fuel specifications and be sourced from a known and reputable
supplier. Clean, fresh and properly specified diesel
fuel will provide assurances of maximum engine performance and maximum fuel injection system longevity.
The use of out-of-spec, dirty or questionable quality
diesel fuel will result in engine performance and startability problems as well as reductions in engine and
fuel injection system life.
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.
All burner combustion system designs are geared
toward the use of commercial grade diesel fuels. As
such, use of fuels other than those designated “DF”,
i.e. DF2 (No. 2 Diesel Fuel), will result in degradation
of performance and/or reduction in component life. It
is understood that applications in certain situations
require the use of fuels other than No. 2 diesel fuel.
Below is a list of various fuels and comments pertaining to each.
Diesel engines are designed to operate on No. 2 diesel
fuel. However, some geographical areas, by virtue of
cold winter temperatures, change the diesel fuel supply
depot to No. 1 diesel fuel in winter months. No. 2 diesel
fuel provides maximum viscosity and lubricity but can
have ‘waxing’ problems at lower temperatures. We expressly recommend the use of No. 2 diesel fuels when
temperatures are at or above 14°F. We recommend
We do not recommend the use of ‘heating oil’, blended
fuel/waste engine oil, or low grade diesel fuel of any
kind. The use of aviation fuels - JP4, JP5 or JP8 must
be approved on an application basis and is not recommended for broad range commercial applications.
Fuel Quality/Storage:
No. 1 and No. 2 diesel fuel degrades with time. No 2 diesel fuel has a storage life of approximately one (1) year.
No. 1 diesel fuel has a maximum storage life of two (2)
years. Further, storage of diesel fuel in contaminated
storage tanks can lead to excessive impurities within
the stored fuel. As such, aged or contaminated diesel
fuel should not be consumed by Lombardini diesel
engines. Aside from the specifications listed above,
fuel measured to have total insolubles >1mg/100mg,
organic matter > 1mg/100ml or rust/mineral matter >
2mg/ml should not be consumed in diesel engines.
Fuel Grade/Type OPERATOR’S MANUAL
In the heating process, fuel residue in the form of soot
deposits, may develop between heating coil pipes
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 on the following page.
that No. 1 diesel fuel be used when temperatures are
at or below 14°F. The use of either EPA - high sulfur,
off-highway diesel fuel or EPA - low sulfur, on-highway
fuel for non-CARB certified engines is allowed. CARB
certified engines must consume only EPA - low sulfur
diesel fuels conforming to EPA 40 CFR 86-113-94.

OPERATOR’S MANUAL
ELECTRODE SETTING
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. The solenoid, which is normally closed,
is activated by a N/O pressure switch. This pressure
will not activate the fuel solenoid until the pressure
washer is being used in the high pressure mode
spraying water. When the trigger on the spray gun is
not compressed or the soap nozzle is in use, the fuel
solenoid is inactive, shutting off the supply of fuel to
the combustion chamber.
Controlling the flow of fuel in this way gives an instantaneous burn-no-burn situation, thereby eliminating high
and low water temperatures, and 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.
Fuel Pressure Adjustment:
To control water temperature, adjust fuel pressure
by turning the regulating pressure adjusting screw
clockwise to increase, counterclockwise to decrease.
Do not exceed 200 psi. NOTE: When changing fuel
pump, a bypass plug must be installed in return port
or fuel pump will not prime.

Burner Air Adjustment:
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. 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.
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.
For additional burner component information, see
Burner Assembly Exploded View page. It is recommended
that the oil burner be serviced yearly or as needed.
Contact your local service center.

To adjust, start the machine and turn burner ON.
Loosen two locking screws found in the air shutter
openings (see illustration) 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.

WHAT THIS WARRANTY COVERS
All LANDA pressure washers are warranted by LANDA to the original purchaser to be free from defects in materials
and workmanship under normal use, for the periods specified below. This Limited Warranty is subject to the exclusions
shown below, is calculated from the date of the original purchase, and applies to the original components only. Any parts
replaced under this warranty will assume the remainder of the part’s warranty period.
SEVEN YEAR PARTS AND ONE YEAR LABOR WARRANTY:
Components manufactured by LANDA, such as frames, handles, top and bottom wraps, float tanks, fuel tanks, belt guards,
and internal components on the oil-end of Landa manufactured pumps. Pro-Duty units (PD Series) have a three-year
warranty against material defects and workmanship. General, AR, Legacy, Comet and swash and wobble plate pumps
have a one year warranty. Heating coils have a five year warranty from date of original machine purchase.
ONE YEAR PARTS AND ONE YEAR LABOR WARRANTY:
All other components, excluding normal wear items as described below, will be warranted for one year on parts and
labor. Parts and labor warranty on these parts will be for one year regardless of the duration of the original component
manufacturer’s part warranty.
WARRANTY PROVIDED BY OTHER MANUFACTURERS:
Motors, generators, and engines, which are warranted by their respective manufacturers, are serviced through these
manufacturers’ local authorized service centers. LANDA is not authorized and has no responsibility to provide warranty
service for such components.
WHAT THIS WARRANTY DOES NOT COVER
This warranty does not cover the following items:
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
protectors.
2. Damage or malfunctions resulting from accidents, abuse, modifications, alterations, incorrect installation, improper servicing, failure to follow manufacturer’s maintenance instructions, or use of the equipment beyond its
stated usage specifications as contained in the operator’s manual.
3. Damage due to freezing, chemical deterioration, scale build up, rust, corrosion, or thermal expansion.
4. Damage to components from fluctuations in electrical or water supply.
5. Normal maintenance service, including adjustments, fuel system cleaning, and clearing of obstructions.
6. Transportation to service center, field labor charges, or freight damage.
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 manufacturers, 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
IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF
MERCANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY LIMITED TO THE DURATION
OF THIS WRITTEN WARRANTY. LANDA does not authorize any other party, including authorized LANDA Dealers, to
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.
