CHAPTER 1
INTRODUCTION AND
GENERAL INFORMATION
1.0 INTRODUCTION
This manual is provided for the owners of
Wipaire model 8750 Floats as installed on the
Cessna 208 Caravan and 208B Grand Caravan.
It has two main priorities:
To inform owners of the level and amount of
servicing required to properly maintain their
floatplane, and to provide technical data and
servicing as specified to maintenance
professionals charged with servicing the floats.
The service products referred to throughout this
manual are described by their trade names and
may be purchased from the Wipaire Parts
Department.
We, at Wipaire, welcome your purchase and
look forward to years of satisfying exchanges
with you. Your floats are built with pride and
attention to detail, but we want that care to
extend beyond your purchase. Our customer
service department is available for your
questions 24 hours a day, 7 days a week, where
ever you are in the world.

In this service manual we have worked hard to
include many repair scenarios in addition to the
recommended products, practices, and routine
maintenance required to keep your floats in
working order.
When a float part is significantly changed or
an additional inspection is recommended or
required, often a service letter and/or kit is
issued. If a warranty is issued, most
commonly it is for an 18 month time period,
so it is crucial to check for service letters
specific to your float model at each periodic
inspection to be eligible.
Service Manuals and the installation prints
included are also revised periodically and
also to be kept updated. Service letters,
Service Kits and Service Manuals are
available on our web site at no charge,
www.wipaire.com.
NOTE:
IT IS CRITICAL TO CHECK FOR
MANUAL UPDATES EACH TIME AN
INSPECTION IS EXECUTED.
