BLAST POT WARRANTY

MMLJ, INC. LIMITED WARRANTY

IMPORTANT: Terms of Warranty

MMLJ, Inc. warrants that the product you have purchased is free from defects in materials or workmanship under normal use during the 
warranty period. Your sales receipt, showing the data of purchase for this product, is your proof of the date of purchase. This warranty 
is valid only if the product is assembled/installed according to the instructions included with the product. This warranty extends only to 
you, the original purchaser. It is not transferable to anyone who subsequently purchased the product from you.

During the warranty period, MMLJ, Inc. will repair or replace (at MMLJ, Inc.’s option) the product if it becomes defective or otherwise 
fails to conform to this Warranty under normal use. In repairing the product, MMLJ, Inc. may replace defective part with new, or at the 
option of MMLJ, Inc., serviceable used parts that are equivalent to new parts in performance. MMLJ, Inc. reserves the right to change 
manufacturers of any part to cover any existing warranty. This extends to items normally covered by a manufacturer other than MMLJ, 
Inc. used on this product within the first calendar year of purchase. 

This warranty does not cover shipping charges; export taxes, custom duties and taxes, or any other charges associated with 
transportation of the parts or products. To obtain warranty service, you must contact MMLJ, Inc.’s customer service representative. 
Any parts determined to be defective must be brought to the attention of MMLJ, Inc. within 6 months of delivery of equipment. You 
must prepay any shipping charges, export taxes, custom duty taxes, or any other charges associated with transportation of the parts or 
product. In addition, you are responsible for insuring any parts or product shipped or returned. You assume the risk of loss during the 
shipment. You must present MMLJ, Inc. with proof-of-purchase documents (including the date of purchase). Any evidence of alteration, 
erasure, or forgery of proof-of-purchase documents will be cause to void this warranty. 

The warranties listed above do not extend to any product that has been damaged or rendered defective (a) as a result of accident, 
misuse, or abuse (b) by the use of parts not manufactured or sold by MMLJ, Inc. and/or (c) by modification or improper installation of 
the product. Product on which the serial number has been defaced or removed is not eligible for warranty service. Should any product 
submitted for warranty service be found ineligible, an estimate of repair cost will be furnished and the repair will be made if requested 
by you upon MMLJ receipt of payment or acceptable arrangements for payment. Except, as expressly set forth in this warranty, MMLJ 
makes no other warranties, expressed or implied. This is the only express warranty applicable to Dustless Blasting® branded products. 
MMLJ does not assume, nor authorize anyone to assume for it any other express warranty. 

BLAST POT, LIMITED LIFETIME WARRANTY:

This warranty applies only to pressure vessels manufactured by MMLJ, Inc. under the Dustless Blasting® brand name. This product is 
backed by a limited lifetime warranty, excluding only expendable parts such as gauges and valves (which are covered by manufacturer 
other than MMLJ, Inc.) and paint.  

This Limited Warranty does not extend to any product that has been damaged or rendered defective (a) as a result of lack of 
maintenance, accident, misuse, or (b) abuse by the use of parts not manufactured or sold by MMLJ, Inc. and/or (c) by modification or 
improper installation of the product.
