UNPACKING

 

As a part of our system of quality control,   
every STK product is carefully inspected   
before leaving the factory to insure flawless 
appearance.  
After unpacking, please inspect for any physical 
damage. Save the shipping carton and all 
packing materials, as they were carefully 
designed to reduce the possibility of 
transportation damage should the unit again 
require packing and shipping.   
In the event that damage has occurred, 
immediately notify your dealer so that a written 
claim to cover the damage can be initiated with 
the carrier. The right to any claim against a public 
carrier can be forfeited if the carrier is not 
promptly notified and if the shipping carton and 
packing materials are not available for inspection 
by the carrier. Save all packing materials until the 
claim has been settled.
