DESCRIPTION:
KOMATSU 960E-1 DUMP TRUCK Operation & Maintenance Manual (SN :A30025 – A30026) KOMATSU 960E-1
- 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.
- 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. 960E).
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 identifies the original manufacturing 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 components. The vehicle design and application guidelines are sensitive to the maximum GVW. GVW is total weight: empty vehicle weight + fuel & lubricants + payload.
