SERVICE MANUAL

Introduction

This manual details the steps necessary to replace many components on the LX810. It is not intended to

be a comprehensive manual for replacing all parts on the LX810. Instead it is broken down into modules or

assemblies. The manual explains how to replace the entire assembly, not specific parts on each assembly.

The assemblies included in the manual are the ones most likely to be damaged or need replacement after

extensive use.

You will need only a few tools to complete these repairs. A T10 Torx screwdriver, a Phillips #1 screwdriver

and a straight screwdriver are required. Long shank screwdrivers work best. For ease of use, the

screwdrivers should be magnetized.
