Unsafe use of this machine may cause serious injury or death. Operators and maintenance per-
sonnel must read and understand this manual before operating or maintaining this machine.
This manual should be kept in or near the machine for reference, and periodically reviewed by all
personnel who will come into contact with it.
This material is proprietary to Komatsu America Corp (KAC), and is not to be reproduced, used, or dis-

It is the policy of the Company to improve products whenever it is possible and practical to do so. The
Company reserves the right to make changes or add improvements at any time without incurring any obli-
gation to install such changes on products sold previously.

NON-OEM PARTS IN CRITICAL SYSTEMS
For safety reasons, Komatsu America Corp. strongly recommends against the use
of non-OEM replacement parts in critical systems of all Komatsu equipment. Critical
systems include but are not limited to steering, braking and operator safety sys-
tems.
Komatsu is also aware of repair companies that will rework or modify an OEM part
for reuse in critical systems. Komatsu does not generally authorize such repairs or
modifications for the same reasons as noted above.
Use of non-OEM parts places full responsibility for the safe performance of the
Komatsu product on the supplier and user. Komatsu will not in any case accept
responsibility for the failure or performance of non-OEM parts in its products,
including any damages or personal injury resulting from such use.
FOREWORD
This manual is written for use by the operator and/or the service technician. It is designed to help these persons to
become fully knowledgeable of the truck and all of its systems in order to keep it operating safely and efficiently. All
operators and maintenance personnel should read and understand the information in this manual before operating
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 the truck or performing repairs on the truck.
The first section covers component descriptions, truck specifications and safe work practices, as well as other
general information. The major portion of the manual pertains to disassembly, service and reassembly. Each major
serviceable area is dealt with individually. For example, the disassembly, service and reassembly of the radiator
group is discussed as a unit. The same is true of the engine and engine accessories, and so on through the entire
mechanical detail of the truck. Disassembly should be carried only as far as necessary to accomplish needed
repairs.
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.
This manual shows dimensioning of U.S. standard and metric (SI) units throughout. All references to “right,” “left,”
“front,” or “rear” are made with respect to the operator's normal seated position unless specifically stated otherwise.
When assembly instructions are provided without references to specific torque values, standard torque values
should be used. Standard torque values are shown in torque charts in the General Information section of this
manual. Specific torques, when provided in the text, are in bold face type, such as 135 N•m (100 ft lbs). All torque
specifications have ±10% tolerance unless otherwise specified.
A product identification plate is located on the frame in front of the right side front wheel. It designates the Truck
Model Number, Product Identification Number (vehicle serial number), and Maximum GVW (Gross Vehicle Weight)
rating.
The KOMATSU truck model designation consists of three numbers and one letter (i.e. 930E).
The three numbers represent the basic truck model.
The letter “E” designates an Electrical wheel motor drive system.
The Product Identification Number (vehicle serial number) contains information which identifies several
characteristics of this unit. For a more detailed explanation, see the end of Section A4.
The Gross Vehicle Weight (GVW) is what determines the load on the drive train, frame, tires, and other
components. The vehicle design and application guidelines are sensitive to the maximum GVW.
GVW is total weight: empty vehicle weight + fuel & lubricants + payload.
To determine the allowable payload, fill all lubricants to the proper level and fill the fuel tank of an empty truck
(which includes all accessories, body liners, tailgates, etc.), and then weigh the truck. Record this value and
subtract it from the GVW. The result is the allowable payload.
NOTE: Accumulations of mud, frozen material, etc, become part of the GVW and reduces the allowable payload.
To maximize payload and to keep from exceeding the maximum GVW rating, these accumulations should be
removed as often as practical.
Exceeding the allowable payload will reduce the expected life of truck components.

GRADE/SPEED CHART
A grade/speed retard chart is located on the left front
post of the operator's cab. It provides the
recommended maximum speeds to be used when
descending various grades with a loaded truck.
Always refer to the decal in operator's cab. This
decal may change with optional truck equipment
such as wheel motor drive train ratios, retarding
grids, tire sizes, etc.
ROPS/FOPS
A plate attached to the right rear corner of the cab
states that the Rollover Protective Structure (ROPS)
and Falling Object Protective Structure (FOPS) meet
various SAE performance requirements.
The plate also contains a WARNING about making
modifications or repairs to the structure.
Unauthorized modifications or repairs will void the
certification.
LUBRICATION CHART
The lubrication chart is mounted on the right hand side of the radiator grille structure. Refer to Section P,
Lubrication and Service, in the shop manual for more complete lubrication instructions.

NOTE: Tables such as Table VIII, IX, X, and XI may be used as in the following example:
Example: Convert 975 psi to kilopascals (kPa). 3. Multiply by 10:
970 psi = 6688 kPa.
1. Select Table X.
4. Go to psi row 0, column 5; read 34.475
2. Go to psi row 90, column 7; read 668.8
psi = 34.47 kPa. Add to step 3.
97 psi = 668.8 kPa.
5. 970 + 5 psi = 6688 + 34 = 6722 kPa.
