MACHINE OPERATION WHEN SWINGING OR CHANGING DIRECTION OF TRAVEL Before operating the machine or the work equipment, always observe the following precautions to prevent serious injury or death. When changing the direction of travel from forward to reverse or from reverse to forward, reduce speed early and stop the machine before changing the direction of travel. Sound the horn to warn people in the area. HAOA190L Figure 17 Check that there is no one in the area around the machine. There are blind spots behind the machine, so if necessary, swing the upper structure to check that there is no one behind the machine before traveling in reverse.
When operating in areas that may be hazardous or have poor visibility, designate a person to direct work site traffic. Ensure that no unauthorized person can come within the turning radius or direction of travel. Be sure to observe the above precautions even if a travel alarm or mirrors are installed. TRAVEL PRECAUTIONS Never turn the starting switch to the "O" (OFF) position when traveling. It is dangerous if the engine stops when the machine is traveling. It will be impossible to operate the steering. Attachment control levers should not be operated while traveling. Do not change selected travel mode (FAST/SLOW) while traveling.
Fold in work equipment so that the outer end of the boom is as close to the machine as possible, and is 40-50 cm (16 - 20 in) above ground. Never travel over obstacles or slopes that will cause the machine to tilt severely. Travel around any slope or obstacle that causes the machine to tilt 10 degrees or more to the right or left, or 30 degrees or more from front to rear. Do not operate the steering suddenly. The work equipment may hit the ground and cause the machine to lose its balance, and this may damage the machine or structures in the area. When traveling on rough ground, travel at low speed, and avoid sudden changes in direction. Always keep to the permissible water depth.
Permissible water depth is to the centerline of the upper track rollers. When traveling over bridges or structures on private land, check first that the bridge or structure can withstand the weight of the machine. When traveling on public roads, check with the local authorities and follow their instructions. 1-24 Safety 022-00058E Operation and Maintenance Manual
