Service Manual

This service repair manual is written for use by Authorized Toro Appliance Service Dealers.
Complete Trouble Shooting Guides, Wiring Diagrams and Service Instructions are included.
The manual
is divided into five sections. The first section concerns itself with the automatic
line feeding devices used in the four different trimmers. The second section deals with the
900 and 1100 Trimmers, the third with the 1200 and the fourth with the Cordless. The fifth
section contains an illustrated
Parts Catalog for each model.
The Trouble Shooting Guides
at the beginning of the first four sections follow a systematic
pattern which will enable you to find
a problem quickly. Each section of the Trouble
Shooting Guide
is numbered in the lower right hand corner. After finding the problem, you
need only refer to this same number in the service section for complete repair instructions.
