TABLE OF CONTENTS

Table Caption: This table outlines the chapter headings of a service or repair manual, covering a wide range of motorcycle components from general information and tools to specific engine parts, chassis systems, and electrical components. It appears to be a comprehensive guide for maintaining and repairing a vehicle.

INTRODUCTION

Introduction

This manual is designed primarily for use by trained technicians in a properly equipped workshop. However, it contains enough detail and basic information to make it useful to the owner who desires to perform his own basic maintenance and repair work. The work can only be carried out if the owner has the necessary hand and special service tools to complete the job.

A basic knowledge of mechanics, including the proper use of tools and workshop procedures is necessary in order to carry out maintenance and repair work satisfactorily. Whenever the owner has insufficient experience or doubts regarding his ability to do the work, an authorised Triumph dealer must undertake all adjustments, maintenance, and repair work.

In order to perform the work efficiently and to avoid costly mistakes, read the text and thoroughly familiarise yourself with procedures before starting work.

All work should be performed with great care and in a clean working area with adequate lighting.

Always use the correct special service tools or equipment specified. Under no circumstances use makeshift tools or equipment since the use of substitutes may adversely affect safe operation.

Where accurate measurements are required, they can only be made using calibrated, precision instruments.

For the duration of the warranty period, an authorised Triumph dealer must perform all repairs and scheduled maintenance.

To maximise the life of your motorcycle:

• Accurately follow the maintenance requirements of the periodic maintenance chart in the Service Manual.
• Do not allow problems to develop. Investigate unusual noises and changes in the riding characteristics of the motorcycle. Rectify all problems as soon as possible (immediately if safety related).
• Use only genuine Triumph parts as listed in the electronic parts catalogue (EPC).
• Follow the procedures in this manual carefully and completely. Do not take short cuts.
• Keep complete records of all maintenance and repairs with dates and any new parts installed.
• Use only approved lubricants, as specified in the Owner's Handbook, in the maintenance of the motorcycle.
