CHAPTER 1 INTRODUCTION AND GENERAL INFORMATION
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 oatplane, and to provide
technical data and servicing as specied to maintenance professionals charged with servicing the oats.
The service products referred to throughout this manual are described by their trade names and may be
purchased from the Wipaire Parts Department.
When performing standard repairs for Wipline Aluminum Floats, please refer to the “Structural Repair Manual For
Wipline Aluminum Floats” part number 1008274. It is available free of charge online at www.wipaire.com.
We, at Wipaire, welcome your purchase and look forward to years of satisfying exchanges with you. Your oats
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 oats in working order.
When a oat part is signicantly 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 specic to your oat model at each periodic inspection to be eligible.
Service Manuals and the installation prints included are also revised periodically and 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.
