than 18 months after shipment from the factory or storage warehouse”, whichever comes first. In case of repair, overhaul 
or other maintenance by Toyo Denki or a company designated by Toyo Denki, the warranty period for the parts concerned 
shall be for 1 year from the date of acceptance inspection. 

 

2. Warranty scope 

(1) Problem diagnosis 

As a general rule, initial diagnosis in the event of product failure should be performed by your company. However, if you 
request initial problem diagnosis, it can be performed on your behalf by Toyo Denki or a member of our service network. 
Please note that if Toyo Denki is not responsible for the cause of the failure, a fee will be charged for the initial diagnosis. 

(2) Repair 

Repair,  part  replacement,  and  onsite  repair  shall  be  provided  free  of  charge.  However,  this  shall  not  apply  in  the 
following cases: 

  When the problem is a result of improper product handling, conditions, environment, usage method, etc., by you or 

your customer 

  When the problem was caused by a system designed by you or your customer 

  When the problem was caused by deficiencies in a program created by you or your customer 

  When the problem originated in something other than the delivered product 

 

  When the problem was caused by modification performed without the prior approval of Toyo Denki 

 

  When the problem was caused by repair or modification performed by someone other than Toyo Denki or a company 

designated by Toyo Denki 

  When the problem was caused by a force majeure such as a natural disaster, fire, or accident. 

  Other cases where Toyo Denki is not responsible for the cause of the problem 

  The free of charge warranty period has expired 

 

3. Disclaimer 

Irrespective of  whether  the  free  of  charge  warranty  period  is  in  effect,  this  warranty shall  not compensate you  or  your 
customer for any damages that are not the responsibility of Toyo Denki, or for any lost opportunity, lost profit, secondary 
damages, or accident due to the failure of the Toyo Denki product concerned. Moreover, compensation shall not be provided 
relating to articles other than the Toyo Denki product concerned. 

 

4. Repair period after product discontinuation 

Once the product has gone out of production, Toyo Denki will continue to provide repair service for the product for a period 
of seven years. However, please note that the procurement of electronic components for the product may become difficult 
during that time, and repair may not be possible. 

 

5. Delivery conditions 

In the case of standard products ordered without test operation and adjustment, delivery shall take place upon product 
arrival at your company, and Toyo Denki shall not be responsible for onsite test operation and adjustments.
