FOREWORD
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 operating
thetruckorperforming maintenance and/oroperationalchecksonthe truck.Allsafetynotices,warningsand 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 interest.
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.
This manual shows dimensioning of metric and (U.S. standard) units throughout. All references to ‘‘Right’’, ‘‘Left’’,
‘‘Front’’,or‘‘Rear’’ aremadewithrespect totheoperator’snormalseatedposition,unless specificallystatedotherwise.
Standard torque requirements are shown in torque charts in the Introduction section and individual torques are
provided in the text in bold face type, such as 723 kg.m (100 ft.lbs.) torque. All torque specifications have ±10%
tolerance unless otherwise specified.
A Product Identification plate is normally located on the truck frame upright in front of the left 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 Haulpak Model designation consists of three numbers and one letter (i.e. 530M). The three numbers represent
thebasic truck model. The letter ‘‘M’’ designatesaMechanicaldrivesystem,andtheletter‘‘E’’ designates an Electrical
wheelmotor drive system.
The Product Identification Number (vehicle serial number) contains information which will identify the original
manufacturingbillofmaterial forthisunit.Thiscompletenumber willbenecessaryforproper ordering of manyservice
parts and/or warranty consideration.
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 total maximum Gross Vehicle Weight (GVW) and
this means the 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.

that most closely describes the specific area of interest to find a page number and go to that page.
Section Numbers and Page Numbers are located at the top, outside corner of the page.
At the top, inside corner of the page is a document (module) number. If there is ever a question regarding the

latest revision date of that page.
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 metric and (U.S. standard) units throughout. All references to ‘‘Right’’, ‘‘Left’’,
‘‘Front’’,or‘‘Rear’’ aremadewithrespect totheoperator’snormalseatedposition,unless specificallystatedotherwise.
When assembly instructions are provided without references to torque values, standard torque values should be
assumed. Standard torque requirements are shown in torque charts on the following pages of this section, and in the
General Information section of the truck service manual. Individual torques when provided in the text are in bold face

STANDARD TABLES
This manual provides dual dimensioning for many specifications. Metric units are specified first, with U.S. standard
units in parentheses. References throughout the manual to standard torques or other standard values will be to one
of the following Tables.
For values not shown in any of the charts or tables, standard conversion factors for most commonly used
measurements are provided in TABLES I and .
NOTE: Portions of this truck may be assembled with SAE (U.S.) hardware.

NOTE: Tables such as Table VI, VII, VIII, IX, and X may be used as in the following example:
Example: Convert 955 kg.m to foot pounds (ft.lbs.).
1. Select Table VI.
2. Go to kg.m row 90, column 5; read 931.7
95 kg.m = 931.7 ft.lbs.
3. Multiply by 10:
950 kg.m = 9317 ft.lbs.
4. Go to kg.m row 0, column 5; read 49.0
5 kg.m = 49 ft.lbs. Add to step 3.
5. 950 +5 kg.m = 9317 +49 = 9366 ft.lbs.

Unless instructions specifically recommend oth-
erwise, these standard torque values are to be
used with simple lithium base chassis grease
(multi-purpose EP NLGI) or a rust- preventive
grease (see list, this page) on the threads.
•Torques are calculated to give a clamping force
of approximately 75% of proof load.
•The maximum torque tolerance shall be ±10% of
the torque value shown.

GENERAL SAFETY
This safety section also contains precautions for optional equipment and attachments.
SAFETY RULES
•ONLY trained and authorized personnel can operate and maintain the machine.
•Follow all safety rules, precautions and instructions when operating or performing maintenance on the machine.
•When working with another operator or a person on worksite traffic duty, be sure all personnel understand all
hand signals that are to be used.
SAFETY FEATURES
•Be sure all guards and covers are in their proper position. Have guards and covers repaired if damaged.
(See Walk-Around Inspection, Operating Instructions - Section 3)
•Learn the proper use of safety features such as safety locks, safety pins, and seat belts, and use these safety
features properly.
•NEVER remove any safety features. ALWAYS keep them in good operating condition.
•Improper use of safety features could result in serious bodily injury or death.
CLOTHING AND PERSONAL PROTECTIVE ITEMS
•Avoid loose clothing, jewelry, and loose long hair. They can catch on controls or in moving parts and cause
serious injury or death. Also, do not wear oily clothes because they are
flammable.
•Wear a hard hat, safety glasses, safety shoes, mask or gloves when
operating or maintaining the machine. Always wear safety goggles, hard
hat and heavy gloves if your job involves scattering metal chips or minute
materials----this is so particularly when driving pins with a hammer and
when cleaning the air cleaner element with compressed air. Check also
that there is no one near the machine.
UNAUTHORIZED MODIFICATION
•Any modification made without authorization from Komatsu can create hazards.
•Before making a modification, consult your Komatsu distributor. Komatsu will not be responsible for any injury
or damage caused by any unauthorized modification.
Read and follow all safety precautions. Failure to do so may
result in serious injury or death.
