Manaras warrants its operators to be free from defects in material and workmanship under 
normal and proper use for a period of two years from date of invoice. Mechanical, electrical and 
electronic accessories are warranted for one year from date of invoice. Wearing parts such as 
clutch pads, v-belts, and brake bands are excluded from warranty. 
 
Manaras’ only obligation shall be to repair or replace defective equipment which does not 
conform to the warranty. Manaras shall not be liable for any injury, loss or damage, direct or 
consequential, arising out of the inability to use the equipment. Before using, Buyer and/or the 
ultimate User shall determine the suitability of the product for its intended use, and User 
assumes all risks and liability in connection therewith. The foregoing may not be changed 
except by an Agreement signed by an authorized representative of Manaras.  
 
The articles that are replaced pursuant to the terms of this warranty shall be retained by 
Manaras, and the User is responsible for any freight costs relating to repair or replacement. 
 
The foregoing warranty is exclusive and in lieu of all other warranties of quality, whether written, 
oral or implied (including any other warranty of merchantability or fitness for purpose). 
 
The following are exclusions from warranty: 
•  If usage, product modification, adaptation or installation are not in accordance with our 

installation and operating instructions. 

•  If the product has been opened, dismantled or returned with clear evidence of abuse or 

other damage. 

•  If our written specifications are not properly applied by the Buyer when selecting the 

equipment. 

•  If our written instructions for installation and wiring of the electrical connections have not 

been followed. 

•  If our equipment has been used to perform functions other than the functions it was 

designed to handle. 

•  If Manaras equipment is used with electrical accessories (switches, relays, etc.) that have 

not been previously approved in writing by the Manaras Engineering Department. 

•  If electrical accessories and other components have been used in disregard of the basic 

wiring diagram for which they were designed. 

 
All costs related to installation and reinstallation of the Manaras equipment covered by this 
warranty are not the responsibility of Manaras. Manaras will not be responsible for any 
consequential damages during the following installation procedures. If the Buyer resells any 
Manaras products to another Buyer or End-user, it shall include all of the terms and provisions 
of this warranty in such resale. Manaras’ responsibility to any such Third Party shall be no 
greater than Manaras’ responsibility under the warranty to the original Buyer. 
 

Returns

 

No returns will be accepted without prior written authorization by Manaras. All returns must be 
accompanied by a Return Authorization Number issued by Manaras, and all unauthorized 
returns will be refused. The return shipment is to be freight prepaid by the Buyer, and under no 
circumstances shall the Buyer deduct the value of the returned merchandise from any 
remittance due. A restocking fee of 15% of Manaras sale price will be charged.
