terms and conditions:
Only Service Centers authorized by Alto Professional in writing are authorized to perform service

thereof, any and all warranties of Alto Professional as to that product and any service contract
with Alto Professional for that product shall be voided and shall no longer apply for such product,

and Alto Professional shall have no liability for any such repairs or service work. All such service or
repairs are performed at the sole risk of the person performing the service or repairs. You agree
that all such work will be performed in a competent, professional and safe manner at all times and to
indemnify and fully hold Alto Professional and its successors and assigns harmless in the event of
any failure to so perform.
Your purchase of the Manual shall be for your own ultimate use and shall not be for purposes of
resale or other transfer.
As the owner of the copyright to the Manual, Alto Professional does not give you the right to copy
the Manual, and you agree not to copy the Manual without the written authorization of Alto
Professional. Alto Professional has no obligation to provide to you any correction of, or supplement
to, the Manual, or any new or superseding version thereof.
Alto Professional shall have the right to refuse to sell or otherwise transfer repair parts or materials
to you in its sole discretion. You shall not use, sell or otherwise transfer spare or replacement parts
supplied by Alto Professional to you (i) to repair or be used in products manufactured for or by third
parties or (ii) to any third parties for any purpose.
You shall not make any warranties or guarantees with respect to the products of Alto Professional
or the use thereof on behalf of Alto Professional or in your own name.

other terms shall apply unless in a writing signed by an authorized representative of Alto Professional.
