Two Braun Serial No./Series No. identification tags (shown below) are posted on the lift.
One I.D. tag is posted on the opposite pump side vertical arm. A second I.D. tag is located
on the opposite pump side tower. Both I.D. tags provide the product identification infor-
mation provided on the warranty/registration card. Record the information in the space
provided (or document on a copy). This information must be provided when filing a war-
ranty claim or ordering parts.
Warranty and Registration Instructions
Immediately upon receiving the lift, examine the
unit for any damage. Notify the carrier at once
with any claims.
Two warranty/registration cards (shown right) are
located in the lift-mounted manual storage pouch.
The sales representative must process one of the
cards. The consumer must fill out the other card
and mail it to The Braun Corporation. The warran-
ty is provided in this manual. The warranty cards
must be processed to activate the warranty.
Congratulations
We at The Braun Corporation wish to express our fullest appreciation
on your new purchase. With you in mind, our skilled craftsmen have designed and
assembled the finest lift available.
This manual provides service-related material. Refer to the FMVSS No. 403
Quick Reference Installation Sheet for installation instructions, operating instructions
and maintenance procedures.
Braun Century Series™lifts are built for dependability and will provide years of
pleasure and independence as long as the lift is installed and serviced as specified by
