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.
