TRANSPORTATION 3.4 TRANSPORTATION When transporting the machine, observe all related laws and regulations, and be careful to assure safety. 3.4.1 TRANSPORTATION PROCEDURE As a basic rule, transport the machine by trailer. Select the trailer to match the weight and dimensions given in "5.1 SPECIFICATIONS". Note that the value for the weight and transportation dimensions given in SPECIFICATIONS may differ according to the type of shoe or type of arm or other attachments. 3.4.2 LOADING AND UNLOADING WITH TRAILER When loading or unloading, check that travel speed boost monitor (1) is off, and always travel at low speed.
If the monitor is on, the speed is set to high-speed trav- el, so press travel speed selector switch (2). Monitor (1) goes out and the speed is shifted to low- speed travel. Always keep the one-touch deceleration switch (if equipped) at the OFF position during loading or unload- ing operations. When loading or unloading, run the engine at low speed, travel at low speed, and operate slowly. When loading or unloading the machine, park the trailer on a flat firm road surface. Keep ample distance between the road shoulder and the machine. Use ramps with ample width, length, thickness, and strength, and install them at a maximum slope of 15°.
When using piled soil, compact the piled soil fully to prevent the slope face from collapsing. Remove the mud from the undercarriage to prevent the machine from slipping to the side on the ramps. Remove any water, snow, grease, oil, or other substanc- es stuck to the ramps. Never change the direction of travel when the machine is on the ramps. There is danger that the machine may tip over. Return the machine to the road surface or the trailer platform, then change the direction of travel. It is dangerous to use the work equipment for the loading or unloading operation. Never operate any lever other than the travel lever on the ramps.
The center of gravity of the machine will change suddenly at the joint between the ramps and the truck or trailer, and there is a hazard of the machine losing its balance. Travel slowly over this point. When swinging the upper structure on the trailer or truck, the machine is unstable, so pull in the work equipment and swing slowly. On machines with the cab specification, always check that the sliding door is locked in position, both when it is open and when it is closed. If the door is open or closed on the ramps or on the platform of the trailer, there is danger that the operating effort will suddenly change. Do not open or close the door on the ramps or trailer platform. 134 WARNING
