LANDA LIMITED NEW PRODUCT WARRANTY

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, gas-

kets, 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, im-

proper 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 com-
pleted 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 war-
ranty gives you specific legal rights and you may also have other rights which vary from state to state.
