Do not attempt to assemble this machine until you read and understand the assembly procedure. Improper procedures could result in injury or death.
Before unloading the chassis and components, read the following suggestions, which will make the assembly easier.Previous assembly experience has shown that choosing the correct area is the first step to a smooth, quick assembly.Remove the paint from all contacting surfaces. This is necessary for a good solid joint. Unless specified, all torques are without thread lubricant.Preparation Before Assembly of Machine
A flat, smooth, well-drained area 30 m × 24 m (100 ft. wide × 80 ft. long) is needed. Use the center of the area to set the chassis.Keep the area around the chassis free for the movement of the cranes.As the components are unloaded, set them in a position near the chassis; but not in the way of the cranes. They will not have to be handled again except for installation on the chassis.Set the large wooden boxes of smaller components, sheet metal, mud flaps, and hardware aside and out of the way. Open the boxes to familiarize yourself with their contents. Do not open the bags of hardware. The bags are well marked as to where the contents are used. Place all the bagged hardware in one of the large wooden boxes close to the machine area.As the components are installed, remove the bagged hardware marked for that component from the box.By organizing the hardware as described, the risk of lost hardware is reduced, as well as the time spent searching for parts.The use of these suggestions, the tools and equipment recommended, and a thorough understanding of the Special Instruction will help ensure a smooth, organized assembly.Reference: Parts Manual, Operation and Maintenance Manual, Tool Guide, Truck Service Manual SENR3334 (Air Conditioning & Heating Service Manual, SENR4621 (3500 Vehicular Engines) SENR4705 (Automatic Ether Injection System) and Special Instruction SMHS7867.
Do not let any dirt or foreign material get into the hydraulic system.
Clean all surfaces and remove burrs from all areas where parts are to be installed. Use warm water and detergent to remove the protecting material.Weights
