DETERGENTS AND GENERAL OPERATING TECHNIQUES
PRESSURE WASHER
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.
STEP 1: Connect detergent injector to discharge nipple
on machine. Connect high pressure hose to injector
with quick coupler. (Check to make sure locking coupler
sleeves are in proper position before applying water
pressure).

THERMAL PUMP PROTECTION
If you run the motor on your pressure washer for 1-2
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.
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 2: Use detergent designed
specifi cally 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
fi lter end of detergent suction tube
into the detergent container.
STEP 3: With safety latch on
spray gun engaged, secure black
detergent nozzle into quick coupler. NOTE: Detergent cannot be
applied using a pressure nozzle.
STEP 4: With the motor 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 fl ush the detergent injection
system after each use by placing the suction tube
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
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, other corrosive chemicals
• Liquids containing solvents (i.e., paint thinners,
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.
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 fl owing by simply removing detergent
siphon tube from bottle.

susceptible to permanent damage if
frozen.
FREEZE DAMAGE IS NOT COVERED B Y W A RRANTY.
If you must store your pressure washer in a location
where the temperature is below 32°F, you can minimize
the chance of damage to your machine by draining your
machine as follows:
1. Stop the pressure washer and detach supply hose
and high pressure hose. Squeeze trigger of spray
gun to drain all water from the wand and hose.
2. Restart pressure washer and let it run briefl y (about
5 seconds) until water no longer discharges from

PRESSURE WASHERS
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. General, AR, Liberty, 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 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
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.
