Foreword - Komatsu 730E Operation & Maintenance Manual

OM1032.1 02/03
This manual is written for use by the operator and/or the service technician and is designed to help these persons
to become fully knowledgeable of the truck and all its systems in order to keep it operating safely and efficiently.
All operators and maintenance personnel should read and understand the materials in this manual before operat-
ing the truck or performing maintenance and/or operational checks on the truck. All safety notices, warnings and
cautions should be understood and followed when operating or accomplishing repairs on the truck.
The first section is an Introduction to the manual and contains a Table of Contents to locate specific areas of inter-
est. Other sections include Safety, Operation, Maintenance, Specifications, and Optional Equipment.
The illustrations used in this manual are TYPICAL of the component shown and may not be an exact reproduction
of what is found on the truck.
A product identification plate is located on the frame in front of the right side front wheel and designates the Truck
Model Number, Product Identification Number (vehicle serial number), and Maximum G.V.W. (Gross Vehicle
Weight) rating.
The KOMATSU Truck Model designation consists of three numbers and one letter (i.e. 730E).
The three numbers represent the basic truck model.
The letter "M", when present, designates a Mechanical drive system;
The letter "E", when present, designates an Electrical wheel motor drive system.
The Product Identification Number (vehicle serial number) contains information which will identify the original man-
ufacturing bill of material for this unit. This complete number will be necessary for proper ordering of many service
parts and/or warranty consideration.
The Gross Vehicle Weight (GVW) is what determines the load on the drive train, frame, tires, and other compo-
nents. The vehicle design and application guidelines are sensitive to the total maximum Gross Vehicle
Weight (GVW) GVW is TOTAL WEIGHT: the Empty Vehicle Weight + the fuel & lubricants + the payload.
To determine allowable payload: Service all lubricants for proper level and fill fuel tank of empty truck (which
includes all accessories, body liners, tailgates, etc.) and then weigh truck. Record this value and subtract from the
GVW rating. The result is the allowable payload.
NOTE: Accumulations of mud, frozen material, etc. become a part of the GVW and reduces allowable payload. To
maximize payload and to keep from exceeding the GVW rating, these accumulations should be removed as often
as practical.
Exceeding the allowable payload will reduce expected life of truck components.
