Please take time to read and understand this User's Guide and familiarize 
yourself  with  the  operating  and  maintenance  instructions  before  you  use  
the  product.  We  strongly  recommend  that  the  operator  read  the  Section 
titled “Safety Information” prior to operating the product.

This User's Guide should stay with the product to provide you and all future 
users and owners of the product with important operating, safety and other 
information.

We  identify  the  parts  to  which  you  need  to  pay  special  attention  in  the 
document  with  underscore.  Please  notice  those  information  to  avoid  the 
unnecessary damages.
